What's In Your Wrinkle Cream? by jerry brown What's In Your Wrinkle Cream?Anti-aging skin-care products promise to get rid of wrinkles, sun damage and age spots. Do alpha-hydroxy acids, retinoids or vitamin C make a difference? Every year, Americans spend millions on creams and lotions that promise younger-looking skin. But along with the promise of a fabulous face, do you know what else is in the bottle? Here are some of the terms you'll see in beauty products available in your grocery or drug store, or through a dermatologist. Alpha-hydroxy acids (AHA) Alpha-hydroxy acids are made from fruit and milk sugars. They're used to exfoliate the outer layer of the skin in an attempt to reduce fine lines, skin discoloration, age spots and large pores. But their effectiveness in treating wrinkles has not been proven. While using AHA products - and for a week after - you'll need to wear sunscreen and stay out of the sun as much as you can. When you first use AHA, your skin may become irritated. You may want to use only AHA products every other day at first. AHA may be listed on the label as glycolic acid or lactic acid. Antioxidants Antioxidants help your cells repair damage from the sun, smoking and radiation. You'll find them in products containing vitamins A and C. Their effectiveness as topical agents in treating wrinkles has not been proven, but studies are being done. Beta-hydroxy acid This ingredient also exfoliates skin, but is less irritating than alpha-hydroxy acid. It works by penetrating hair follicles. It's a common ingredient in acne products, and is available in over-the-counter products or by prescription. Look for salicylic acid on the label. Collagen Collagen is a protein found in all human and animal tissue. It makes up 75 percent of your skin, and gives firmness and structure to the skin. The collagen used in skin treatments is often made from cow protein. People who are allergic to cow-derived collagen can use self-donated or tissue-donor collagen. Collagen is used to temporarily improve scars, and for wrinkles such as smile and frown lines and crow's feet. Collagen injections are also used to make lips fuller. The effects of collagen last for three to 12 months. Shots are given in a series of treatments. Some people may have severe allergic reactions that can lead to pain and scarring. Comedogenic These are cosmetics that cause blackheads and whiteheads. Products that are noncomedogenic are less likely to cause breakouts. However, no single product is noncomedogenic for everyone. Someone who has very oily skin may still get breakouts from a product that might be fine for another person with mildly oily skin. If you are acne-prone or have oily skin, look for a moisturizer that is noncomedogenic. You may not need a moisturizer if you live in a humid climate. Copper Peptide Copper peptides help the body make collagen and elastin. Sun damage and aging cause the body to make less of these proteins. Thus, some think that copper peptides may help repair sun-damaged skin. Some skin care products that contain copper peptide are sold over the counter. Other forms of copper are toxic and should not be used. Elastin This is a protein found in the second layer of skin. It makes skin elastic. Along with collagen, elastin gives structure to your skin. Repeated sun exposure breaks down elastin. As skin becomes less elastic, it also becomes drier and its fat padding disappears. With the loss of that underlying support, the skin may sag and look less supple. Exfoliants These are products that exfoliate, or remove, dead skin cells. Chemical exfoliants include: Alpha-hydroxy acid (AHA)Beta-hydroxy acidPolyhydroxy acid Physical exfoliants are facial scrubs that contain small, rough particles to remove the top layers of cells. Eye creams Your eye area is often the first place where the signs of aging appear. The skin is thinner in the eye area and is affected by smiling and squinting. Dry skin highlights wrinkles and fine lines. Eye creams lessen the appearance of fine lines, but they can't erase them. Take care to use products made specifically for the eye area around your eyes. Do not use general facial moisturizers. They may be too strong for the fragile eye area. Free radicals These are the natural byproducts made by the oxidation of cells. Left unchecked, they can damage your skin, and cause it to age quickly. They may even cause skin cancer. Antioxidants mop up the free radicals, but it is not known how this affects the formation of wrinkles. Glycolic acid (See alpha-hydroxy acids) Humectant These are ingredients in moisturizers that attract water from air into the skin. Humectants, especially glycerin and alpha-hydroxy acids, are the main ingredients in moisturizers. Most dry skin lacks moisture rather than oil, so humectants and moisturizers are used instead of creams or oils. The most effective humectants are alpha-hydroxy acids, especially lactic acid. Other humectants are propylene glycol, sorbitol, hyaluronic acid and urea. L-Ascorbic Acid This is the form of vitamin C most often found in skin care products. (See vitamin C) Retinol (See vitamin A) Salicylic acid (See beta-hydroxy acid) Sun Protection Factor (SPF) Keep in mind that the best way to fight aging skin and skin cancer is to limit your time in the sun. Every day, wear sunscreen that protects your skin from both UVA and UVB rays. Sunscreen should have a sun protection rating of 15 or higher. Every sunscreen product is assigned a number from 2 to 50, representing how much protection it gives you. If you can usually stay in the sun for 10 minutes before you burn, a product labeled SPF 8 is presumed to let you stay in the sun for eight times longer - 80 minutes - before burning. Keep in mind, though, that many factors are involved. Some of these include your skin type, moisture, activities like swimming, and how much and how often you apply the sunscreen. Higher SPF products contain more chemical sunscreens, which could irritate sensitive skin. The best SPFs, especially for the face, are between 15 and 25. Always follow directions on the product about when, where and how much to put on. Vitamin A Vitamin A is also known as retinol. When used topically, it is the most scientifically proven product to reduce roughness and fine lines caused by sun damage. Retinoids, the prescription versions of vitamin A, are rubbed on the skin. Many over-the-counter skin care products in the grocery store contain retinol. Tretinoin, one of the retinoids, is the strongest. It is the active ingredient in the prescription medications Retin-A, Avita and Renova. Bear in mind that this is not a miracle drug that will erase all your sun damage. All of these vitamin A products are for external use only. Tretinoin Tretinoin, a retinoid, is a prescription medicine applied to the skin. It's used to treat sun-damaged skin, wrinkles and rough skin. It has been shown to be effective in improving the appearance of fine wrinkles. Other forms of tretinoin are used for acne.Ressource:https://healthlinerx.helpsite.com/articles/111074-acheter-tadalafil-en-ligne Vitamin C The benefits of vitamin C, an antioxidant, are harder to get from a cream. This is because when it is exposed to the air, its effectiveness decreases. Studies are being done to see how well some of these preparations work in preventing sun-damage and wrinkles. Vitamin E This is another antioxidant. However, its topical use has not been proven to prevent wrinkles or other sun damage.Ressource: https://chinnurology.com/accutane/
