The Difference Between Yellow and Ivory Shea Butter

 Shea Butter

I am often asked what is the difference between Yellow or White Shea Butter, which is better yata yata… First shea butter comes in those small nuts and the color is an off white or biegey or ivory kind of color. They parboil the shea nuts and then it goes to a milling process. You can actually search for videos of women making the shea butter in a more detailed process (google or U tube). I am not going that far into the details just briefly to explain the yellow coloring.  So the yellow and white come from the same Shea Nuts but are processed differently. For the yellow shea butter, a root from the borututu tree is added in the milling process, and gives it that tumeric yellow color.  Some think palm oil is added to give it that yellow color but no palm oil is required to make yellow shea butter, it goes through the same process as the white shea butter. Therefore they both have same qualities. FYI some african make a tea from the bark of the borututu trea that is said to help with liver functions.

So again, the yellow and white shea butter are from the same Karite Tree but are procesed differently.  The Karite tree is grown in Central and Western Africa. Some people confuse Kpangnan African Butter with Shea Butter because it is also yellow.  You will find some vendors selling this butter under the name Yellow Shea Butter, most don’t know the difference but some do, but will tell you it is the same because of the popularity of Shea Butter.  Kpangyan Butter is grown in Central Togo and is used for skin care.

Now Shea Butter also has different grades, Grade A is usually reffered as the white unrefined 100% Raw Shea Butterit can be consumed and used in the comestic arena. It contains more shea nuts than grade B sheabutter. Now Grade B shea butter comes in white and yellow but has *less shea nuts ( I know kind of hard to explain), it actually seems softer than grade A. Grade B shea butter can not be used for consumption only in cosmetics. * I think the meaining of less nuts is that through the process the Shea Butter Nuts get smaller. So that is what’s meant by it has less shea butter. Remember they parboil the nuts, let them dry, sort them, mill them, boil them, cover and let them sit again, so as the process goes on the butter balls get smaller.( Sorry trying to explain as simple as possible.)

Refined Shea Butter – cleaned, bleached, and deorderized – can not be used in cold process soap but can is usually added to cosmetics such as lotions and creams.
Unrefined Shea Butter – as it is smells nutty and is off whitish, can be used in cosmetics and cold process soap.

There is even Organic Shea Butter, this where some might disagree with me which is fine, I think that’s a bunch of Hooplah. If its is 100% Raw Shea Butter then it is just the same quality as Organic, it is the same Karite tree. I feel its just another reason to charge you extra money.

In some cultures, the condition of one’s skin is the ultimate sign of one’s beauty. Learn how to keep your skin soft, smooth, and vibrant at home without expensive luxury products.

Instructions
1

Purchase an ample sized bottle of lotion. It does not have to be expensive lotion from the mall- lotion from the Dollar Store will work just as well. Look for lotions with cocoa butter, vitamin E, and aloe. All of these are good for hydrating your skin.

2

Several times a week in the shower, exfoliate your skin using a loofah and some soap or body wash. Within 5 minutes of getting out of the shower, apply lotion all over your body. Make sure to stay in the hot and steam filled bathroom – this will keep your skin supple and in optimal condition for being moisturized.

3

When exfoliating, rub your loofah in circular motions on areas such as your legs or arms. On tougher areas, such as your elbows and knees, exfoliate with a back-and-forth motion.

4

Drink 4 to 8 glasses of water per day. Eat foods rich in vitamins and minerals (such as fresh fruits or vegetables). Take a multivitamin or a vitamin E supplement.

5

It is difficult to receive completely smooth skin with body hair. If desired, shave your arms and legs (and other areas, if necessary). This will make your skin smooth and soft. However, shaving is not for everyone, and it is hard to stop once you get started.

Overnight Treatments For Razor Bumps

Overnight Treatments for Razor Bumps thumbnail Aloe Vera can soothe razor bumps.

article-new_ehow_images_a07_o0_gk_overnight-treatments-razor-bumps-800x800
Razor bumps occur after shaving the face, pubic area and armpits due to irritation on the skin from the type of razor or frequency of shaving. Those with sensitive skin are most prone to razor bumps. As they can be unsightly and uncomfortable, you likely want to get rid of razor bumps as quickly as possible. There are overnight treatments that can help.

Witch Hazel

Witch hazel is useful for treating razor bumps in all areas. It is appropriate even if the skin is irritated. Witch hazel has astringent and skin healing properties. To use it as an overnight treatment for razor bumps, dip one to three cotton balls in witch hazel and gently dab it on the bumps. Do not rub it on.

Hydrocortisone Cream

A commercial product to use on razor bumps is hydrocortisone cream, which is effective for even the most severe and irritated razor bumps. It also soothes the skin and relieves discomfort. Apply a moderate amount of hydrocortisone cream to the razor bumps by dabbing it on with your finger.

Aloe Vera

Aloe vera is a natural remedy for razor bumps. Apply it overnight to reduce them. It’s best to use the aloe vera gel straight from the plant. To do so, cut open a leaf from the aloe vera plant and squeeze out the gel. Apply the gel directly to the razor bumps. If you don’t have access to a plant, purchase a commercial aloe vera gel. Make sure to choose pure aloe vera with no alcohol added.

Oils

Essential oils soothe razor bumps and the skin around them. They work well on both the face and the body. Some essential oils that work well are tea tree oil, lavender and chamomile oils. Tea tree oil is quite strong and should be mixed with at least one of the other oils. Mix all of the oils together for an extra smoothing treatment. Apply directly to razor bumps.

Three Fundamental Skin Care Techniques No Woman Should Skip


(1) Cleanse skin no more than twice daily with a mild cleaner that doesn’t over dry your skin. Be sure to use a cleanser meant for your skin type (2) Gently exfoliate your skin on a daily basis to remove dead skin cells and expose newer, healthier glowing skin underneath.(3)Apply a moisturizer. A moisturizer with sunscreen of at least SPF 15 should be applied during the day.

If you want your skin to look brighter and better, exfoliation can certainly help! While most people understand exfoliating treatment processes and a routine skin care regimen including exfoliation can buff your dead skin cells off and give you silky results, very few people know how to properly do it. Exfoliation is often something people think they can only get at a dermatologist’s office or in a spa. However, you can get similar results right in your own home, every week. All you need to do is know which products to use and what techniques work best. Use these helpful tips to help you learn how to use the best technique, reduce irritation and get smooth results.

  • Try Exfoliating Gloves:The first step to getting great exfoliation results is to learn how to do it. To get the best results and to softly remove dead skin cells, don’t use a hard sponge to exfoliate. A sponge can create breeding ground for bacteria, because they tend to stay damp. You can get great results for dead skin removal by using exfoliating gloves. Simply lather a cleanser on them and lightly scrub your skin. Just be sure to rinse the gloves well after each use and let them air dry. Some people prefer to use the most costly methods, like microdermabrasion, but you can get great results using these techniques and a good cleansing product.
  • Don’t Scrub Everyday if Skin is Irritated:Remember, you should only be exfoliating two to three times a week. When you exfoliate more than this, you can end up with irritated skin. Most people are terrified of exfoliating because they do it too often, use harsh products during the process or just don’t know what technique to use. To avoid getting bad results, you can also choose to use a soft rag when exfoliating as well, instead of a hard sponge. Of course, if your climate is warmer and you frequently experience more oily skin issues and oil production or perspiration, you’ll have more dead skin cells and may need to exfoliate more often.
  • Use Specialize Facial Scrubs Only:Be sure to use exfoliate skin products that are specifically designed to be used on the facial areas. If you’ve struggled with irritation after using an exfoliating product on your face, it may be because you’re using a body exfoliant cream instead of a cream designed specifically for the sensitive areas of the face. If you’re confused about which products will work best for you, simply visit your nearest Clinique or Sephora counter for assistance.
  • Don’t forget to moisturize! Exfoliation can leave your skin extremely smooth and can even give you a healthy glow. To ensure you get the silky results you desire, always use moisturizer several times a day if you exfoliate regularly. When you exfoliate, the dead skin cells are indeed removed. However, your skin can begin to dry out and get flaky if you don’t keep moisturizer on it at all times and can even bring on more wrinkles. When you do so, exfoliating can make your skin brighter and your skin tone will be more even. It can also lead to smaller pores and reduce the occurrence of pimples.
  • Botox is incredibly popular, but although Botox is a bargain in comparison to other injectables or traditional plastic surgery, it still carries a pretty hefty price tag – at least $10 a unit, with most people requiring between 20 and 40 units every four or six months to “erase” their wrinkles. This year, though, the FDA has approved another botulinum toxin, Xeomin. It’s very similar to Botox, but one small factor could make it much cheaper.Xeomin is a version of botulinum toxin that has already been available to doctors for years. It helps stop muscle spasms, so it’s become a common treatment for people who have chronic neck or eyelid twitching. It’s similar to Botox in effectiveness, lasting time, and safety. Where it differs however, is in storage and preparation. Xeomin could start a price war simply because it’s powdered and doesn’t need to be refrigerated. Botox and previously approved alternative Dysport are both liquids that must be refrigerated at all times, so shipping and storing them isn’t easy. Xeomin, on the other hand, can sit on shelves for years and is simple to mix into saline for injection. And Xeomin’s creator, Merz Pharmaceuticals, just lowered its price by 20 percent, making it even more competitive. It’s a lot less effort and expense for providers, and the hope is that they’ll pass the savings along to consumers.

 

How To Cover Tattoos

Kat_Von_D_Tattoo_Concealer

Instructions
1

Test different concealers or foundations on the tattoo to be covered. The makeup must match perfectly with skin tone. It might take a combination of several colors to get the right match.

2

Prepare the skin by shaving off any hair covering the tattoo. Make up will stick to the hair possibly drawing more attention to the area than the tattoo would.

3

Apply one thin coat of the matched concealer to the tattoo. The makeup should extend over the edges of the tattoo and blend with the skin so there is no defined line between the makeup and the skin. Blend with fingers, a foam wedge or a flat makeup brush. Allow the layer to dry completely.

4

Repeat step three. Apply one very thin coat of concealer, blend and allow it to dry completely. Once it is dry, apply one more coat, blend and allow it to dry.

5

Use the powder brush to reduce shininess by dusting a translucent powder over the tattoo. The powder should be slightly lighter than your natural skin tone. Not only will this tone down the shininess, it will help to set the make up underneath making for a longer lasting finish.

Eye Shadow Tips…

shunblondehairCream eye shadows have emerged in recent years, yet the most common complaint is that they crease and fade quickly. The easy fix is a primer, which preps the skin, allowing the color to act more like a powder. Cream-to-powder formulations, English said, “Start out fluid and amorphous but dry down to set themselves,” so you get both the pigment and longevity. Some cream eye shadows come in a stick and can be applied directly to the eyelid and blended with your fingers. Powder eye shadows can be applied with a brush or your fingertips and are especially good for creating a smoky eye.

Daytime Eye Makeup

Brazen liner, glamorous glitter and mega-lush lashes are a few of our very favorite things, but we know—much to the dismay of our drama-loving hearts—that they’re not always appropriate for daytime settings. To help us walk the fine line between what’s suitable and what’s overkill for the office, we got the five rules of daytime eye makeup from professional makeup artist Lashundra Easton.

beautymakeup

1. Avoid Black & Glitter

“First, I believe makeup should be fun and highlight your beauty. However, if you work in a corporate or conservative setting, ‘too-much’ eye makeup is not work appropriate. For example, a dark smoky eye is a no-go for everyday wear at the office. Avoid using colors like black, dark blue or anything glittery,” SHUN advises.

2. Master Subtle Liner

If you love liner, but don’t want to look overly done Shun has two great techniques for subtle liner. “Dash the eyeliner pencil into the lash line—it will make the lashes look fuller,” or “use a cake eyeliner (a water activated, usually potted liner) with a stiff, flat brush. Apply the eyeliner under the lash line for a ‘non-eyeliner’ look.”

3. Lighten Up Your Smoky Eye

If you love yourself a pretty smoky eye, don’t feel like they’re completely banished for daytime. If you opt for “more subtle tones like plums, greys or browns you can create a lovely daytime smoky look. Apply the darkest tone close to the lash line then blend upward toward the crease. You want to create a sunset effect. Then finish it off with a couple of coats of black mascara,” SHUN says.

4. Keep it Simple

If you need inspiration for the perfect daytime eye makeup, Lashundra shared her recipe. “First, I apply a skin tone eye base to brighten my eye. Second, I apply eyeliner under the lash line to make my lashes look fuller. Third, I fill in my eyebrows. The eyebrows frame your eyes, so never forget to define them. Lastly, apply several coats of mascara. It’s a clean, fresh look for everyday.”

5. Wear What You Love  

The most important rule to keep in mind? “Never wear anything you are not confident in. Makeup should bring out our inner confidence. If you love bright shadows go for it, but be sure all colors suit your skin tone and compliment your eye color,” SHUN says. When in doubt, tone down the glamorous looks you love to interpret them for day, and do you, girlfriend.

Understated Makeup For Brown Eyes

One of the favorite makeup tips that professional makeup artists use to make beautiful brown eyes stand out is to use an eye shadow with subtle shimmer and tint of champagne color. It provides contrast so that your eyes really pop out. At the same times it’s neutral which makes it perfect for everyday wear.
When used in combination with dark eyeliner and mascara, the champagne color contrasts more sharply with the lines to create a more dramatic look. You’ll want to try these:

Bobbi Brown’s Metallic Eye Shadow in Champagne Quartz –This is a pinkish kind of champagne that has a lot of shimmer. It is also very easy to blend and stays on for a long time for maximum appeal. It’s $20. Find it at Amazon.com

Du Wop Eyes Eyeshadow Set in Rose has a nice color that works well, too.  Check it out below.

How To Create A Versatile Look

Makeup for brown eyes can easily move beyond neutral. Eye shadow colors in pink and plum create a striking contrast to brown eyes.  It’s like mauve makeup – it’s perfect, but it contains more tint that works for your eye color. The warm hues in pink and plum also make brown eyes even more radiant. There are 3 makeup tips you can use right away to make these eyeshadow shades work for you:

Makeup Tip 1.  Go wild and playful by using eye shadow colors in neon or bright pink.

Makeup Tip 2.  For a more subdue tone, use lighter shades of mauve.

Makeup Tip 3.  Dark plums purples can be used to create smokey eyes and elegant-looking lids.

If you want to experiment with the different shades of purple and pink, an eyeshadow palette like the one above is a great choice.  You can use the Du Wop Eyes eyeshadowsets in either Rose or Violet. Each palette set consists of five colors – three powder shades of the same color, a metallic shade for highlight and a matching cream liner. This way you can try out different variations of plum or pink depending on your mood or the occasion. For $32 you’ll be able to mix and match your makeup. Find it at Dermstore.com

Striking Makeup For Brown Eyes

makeup for brown eyes 3If you love green then you’re in luck! Khaki green or forest green eye shadow work perfectly with brown eyes.  Mother Nature attests to the wonderful combination that is brown and green – just think of succulent palm trees.
Makeup artists love to use green eye shadow to liven up brown eyes and give it a hint of playfulness. You can have your pick between earthy greens for a more subdued look and bright, neon greens for a more wild makeup look. This is also a favorite for doing fantasy makeup looks like fairy makeup.

More adventurous souls can try Scott Barnes Eye Ice in Goddess. Developed by the makeup guru Scott Barnes, it’s a shimmery loose powder eye shadow that comes in a jar with a brush applicator. It’s also ultra fine and silky so that blending and smoothing it on is a breeze.

You can even go all out with dramatic eye makeup tips for bold, beautiful and slightly wicked eyes.

Blue Eyeshadow Makeup For Brown Eyes

makeup for brown eyes 4To create a cool gaze pick a blue eyeshadow.  It works for most eye colors and brown eyes are no exception. These makeup tips explain why: Blue eyeshadow, more so bright blues, creates a stark contrast to the neutral brown of the eyes. It can make the eyes more radiant while also giving it a cool, relaxing glow. It is best to choose darker blue eyeshadow for darker-brown colored eyes. For a more playful look, opt for aquamarine or neon blues.  Ready to try one?

A must-have for blue eyeshadow is Urban Decay’s Deluxe Eyeshadow in Electric Blue.  It’s a really intense shade of blue eyeshadow powder that can be blended to create subtle to smokey eyes. It’s very, very smooth on the eyes and feels light and velvety on skin. $18

Even if brown is the most common eye color in the world, a whole plethora of shadows to use as makeup for brown eyes are at your disposal to enhance the natural beauty of your eyes. Just remember this makeup tip – the right eyeshadow can spell the difference between boring brown to captivating chocolate. So don’t be afraid to experiment with different eyeshadow colors until you come up with that shade that is just perfect for you.

What Is Disulfide Bond?

In chemistry, a disulfide bond is a covalent bond, usually derived by the coupling of two thiol groups. The linkage is also called an SS-bond or disulfide bridge. The overall connectivity is therefore R–S–S–R. The terminology is widely used in biochemistry. In formal terms, the connection is a persulfide, in analogy to its congener, peroxide, but this terminology is obscure and is no longer used.

On hydrolysis at pH 7 it yields about 8000 calories per mole, in contrast to the 3000 calories yielded byphosphate esters. The bond stores energy that is used to drive biochemical processes, such as the synthesis of macromolecules,contraction of muscles, and the production of the electrical potentials for nerve conduction.
high-energy sulfur bond an energy-rich sulfur linkage, the most important of which occurs in the acetyl-CoA molecule, the main sourceof energy in fatty acid biosynthesis.
hydrogen bond a weak, primarily electrostatic, bond between a hydrogen atom bound to a highly electronegative element (such asoxygen or nitrogen) in a given molecule, or part of a molecule, and a second highly electronegative atom in another molecule or in adifferent part of the same molecule.
ionic bond a chemical bond in which electrons are transferred from one atom to another so that one bears a positive and the other anegative charge, the attraction between these opposite charges forming the bond.
peptide bond the —CO—NH— linkage formed between the carboxyl group of one amino acid and the amino group of another; it is anamide linkage joining amino acids to form peptides.
