Alpha hydroxy acids (AHAs) for the skin are a group of acids derived from plants and animals that are used in a variety of skin care products. They include daily anti-aging and skin-lightening products, such as serums, toners, and creams, as well as concentrated products that are used in chemical peels from time to time. There are seven types of fruit acids that are commonly used in the manufacture of skin care products. They include: • Citric acid (from citrus fruits) • Glycolic acid (from sugar cane) • Hydroxycaproic acid (from royal jelly) • Hydroxycaprylic acid (from animals( • Lactic acid (from lactose or other carbohydrates( • Malic acid (from the fruit( • Tartaric acid (from grapes ( There is extensive research into the uses and efficacy of fruit acids for the skin. However, of all the available AHAs, glycolic and lactic acids are the most promising and most researched. These two compounds are also unlikely to cause irritation. For this reason, most over-the-counter fruit acids contain glycolic or lactic acid. Fruit acids are used primarily for exfoliation. They can also help with: • Promote collagen and blood flow • Correcting pigmentation caused by scars and age spots • Improving the appearance of surface lines and wrinkles • Prevent acne breakouts • Lighten your skin • Increase product absorption 1- Exfoliation Fruit acids are primarily used to exfoliate the skin. In fact, this is the basis for all the other benefits that fruit acids offer. Exfoliation refers to a process in which skin cells on the surface of the skin shed. This helps remove dead skin cells but also generate new skin cells. As you age, the normal skin cell cycle slows down, which can lead to a buildup of dead skin cells. When you have a lot of dead skin cells, they can build up and make your skin look dull. The buildup of dead skin cells can also promote other underlying skin problems, such as: • wrinkles • Pigmentation • Acne However, not all fruit acids have the same exfoliating power. The amount of exfoliation is determined by the type of fruit acid you use. As a general rule, the more AHAs in a product, the stronger the exfoliating effects will be. Get soft and healthy skin with KUO'S Renewal Biological Paraben-free Ampoules that exfoliate and moisturize the skin with ingredients proven by scientific research and rich in the highest quality alpha hydroxy acids such as lactic acid, glycolic acid and citric acid. 2- Skin lightening When these acids exfoliate your skin, dead skin cells are dissolved. The new skin underneath appears brighter and more vibrant. Alpha hydroxy acids combined with glycolic acid can help break down skin cell buildup, while products containing citric acid can increase your complexion's radiance. KUO'S Renewal Serum is enriched with fruit acids to regenerate skin cells without causing irritation or sensitivity to the skin and helps to form new cells that are even-toned for a brighter complexion. It is free of harmful parabens. 3- Reduce and correct discoloration Your risk of skin discoloration increases with age. For example, brown spots, known as pigmentations, may appear as a result of exposure to sunlight. They tend to appear on areas of the body that are exposed to the sun most often, such as your chest, hands, and face. Discoloration may also result from: • Melasma • Post-inflammatory hyperpigmentation • acne scars Skin Fruit Acids promote skin cell renewal. New skin cells are uniform in color. In theory, long-term use of fruit acids may reduce skin discoloration by encouraging the regeneration of old, non-uniform skin cells. The American Academy of Dermatology recommends the use of glycolic acid for discoloration. KUO'S Renewal Cleansing Gel is a blend of the highest quality alpha-hydroxy fruit acids, lactic acid and glycolic acid. Each of them strengthens the effect of the other, as we get a more effective result than if each one is used separately. 4- Promote collagen production Collagen is a protein-rich fiber that helps keep your skin plump and smooth. As you age, these fibers break down. Exposure to sunlight may also accelerate collagen destruction. This can lead to pale and sagging skin. Collagen itself is found in the middle layer of your skin (the dermis). When the top layer is removed, products such as fruit acids can act on the dermis. Fruit acids help boost collagen production by getting rid of old collagen fibers to make room for new ones. Scrub with fruit acids from Dolcevita promotes a gentle and deep cleansing of the skin by stimulating cell renewal and the production of collagen and elastin. It gives the face skin a brighter and uniform aspect. 5- Promotes blood flow to the skin Fruit acids for the skin contain anti-inflammatory properties that can help promote blood flow to the skin. This can help correct dull skin. Healthy blood flow also ensures that the skin cells get the necessary nutrients they need via the oxygen-rich red blood cells. KUO'S Renewal Oxygenating Cream, with fruit acids and hyaluronic acid, gives the skin the oxygen needed to breathe, removes spots, moisturizes the skin, increases skin elasticity, and visibly hides wrinkles. 6- Acne treatment and prevention You may be familiar with benzoyl peroxide and other acne-fighting ingredients for stubborn pimples. Fruit acids for the skin may also help treat and prevent acne recurrence. Acne pimples appear when your pores become clogged with a mixture of dead skin cells, oil (sebum), and bacteria. Exfoliating the skin with fruit acids can help loosen and remove blockages. Continued use may also prevent any future blockages from forming. AHAs may also reduce the size of enlarged pores, which are commonly seen in acne-prone skin. The regeneration of skin cells caused by exfoliation of glycolic and lactic acids can reduce acne scars. Some acne products also contain other fruit acids, such as citric and malic acids, to help soothe inflamed skin. Fruit acids are not only for your face! You can use their products on other acne-prone areas, including the back and chest. According to the Mayo Clinic, it may take two to three months before you start seeing significant improvement in your acne. It's important to be patient while the products work to treat your acne over time. You also need to use the products regularly – not sticking to your daily treatment plan makes it take longer for the ingredients to work. KUO'S Renewal Serum has a therapeutic effect on enlarged pores and acne as it gently exfoliates the skin and helps pores breathe. 7- Reduces the appearance of wrinkles Skin fruit acids are known for their anti-aging effects, and include expressive skin lines. One 2015 study reported that 9 out of 10 volunteers who used fruit acids over a three-week period experienced a significant improvement in overall skin texture. However, it is important to remember that AHAs work on surface lines and wrinkles only, not deep wrinkles. Fillers from a doctor, as well as other procedures such as laser peels, are the only methods that work on deep wrinkles. Dolcevita Fruit Acid Scrub promotes gentle and deep cleansing of the skin, stimulates cell renewal and collagen and elastin production, giving facial skin a brighter, more even appearance and treating wrinkles. 8- Increase the absorption of other products In addition to their distinctive benefits, fruit acids for the skin can make your existing products work better by increasing their absorption by the skin. For example, if you have too many dead skin cells, your daily moisturizer stays on top without wetting the new skin cells underneath. Fruit acids like glycolic acid can penetrate this layer of dead skin cells, enabling your moisturizer to hydrate new skin cells more effectively. To increase the absorption of your daily product, try a toner before using a serum or moisturizer, such as KUO'S Renewal Toner with AHAs. What is the required amount of fruit acids? As a general rule, the FDA recommends fruit acid products with a total concentration of less than 10 percent. This helps prevent their side effects. You should not use products that contain more than 15 percent fruit acids. Daily use products — such as serums, toners, and moisturizers — contain lower concentrations of AHAs. For example, a serum or toner might contain a 5 percent concentration of it. Are side effects possible? If you haven't used fruit acids for the skin before, you may experience minor side effects as your skin adjusts to the product. Temporary side effects may include: • sensitive • blisters • Dermatitis (eczema) To reduce the risk of irritation, he recommends using fruit acid products day in and day out. When your skin gets used to it, you can then start using it every day. Also, be careful when going out in the sun. The exfoliating effects of highly concentrated AHAs may make your skin more sensitive to UV rays for up to a week after use. You should wear sunscreen daily and reapply frequently to prevent sunburn.
