As we age, the body’s metabolism slows down, and so does the skin’s metabolism. In addition, keratin, which should be metabolized naturally, is affected by skin aging, makeup, incomplete cleansing, sun exposure, oil, chaotic work and rest, weather changes, etc., and becomes unable to peel off properly. These old keratin accumulates on the surface of the skin, making the skin dull and rough, fine lines and wrinkles appear, makeup is more difficult to apply, even the best absorption of the essence feels like floating on the face is not fully absorbed, the weather becomes dry and cold, the situation becomes more and more serious. After the age of 25, skin metabolism slows down and keratin accumulates, what should I do? Proper exfoliation is important. However, over-exfoliation may again encounter the skin getting drier and drier, or even let the new keratinocytes buckle due to dehydration. So, the key step in fall and winter skincare is to revitalize the skin and remove old keratin while keeping fresh keratinocytes hydrated and well-fitted. Exfoliation is not just about “scrubbing off the dead skin”, it’s about peeling off the old while promoting keratin renewal. In order to achieve this goal, do not use the rough “scrub” method, use a more gentle way to treat cuticles! Chemically Gentle Exfoliation: Fruit Acid Resurfacing What is fruit acid? Fruit acids are ingredients extracted from natural fruits (grapes, apples, lemons, sugar cane, including milk, etc.), which are mildly acidic and non-irritating to the human skin, and have the miraculous effect of moisturizing the skin and slowing down the aging process. How does fruit acid resurface the skin? Chemical exfoliation refers to skin resurfacing by dissolving keratin with fruit acids, such as citric acid, glycolic acid, salicylic acid, and gluconolactone (PHA), to smooth skin and improve roughness and dullness. The four layers of effects of fruit acids on exfoliation Fruit acids have an improving effect on all layers of the skin, penetrating layer by layer to create healthy skin from the inside out. Layer 1 Promotes the exfoliation of old keratin for a smoother feel. Fruit acids work by loosening the bridges between keratinocytes and gradually exfoliating the skin’s surface to reduce the burden on the skin, while quickly increasing the skin’s ability to absorb nutrients. Layer 2 Accelerates melanin metabolism, lightens spots and brightens skin. By activating the metabolism of skin cells and accelerating the skin cycle, Fructo acid can accelerate the metabolism of pigment cells, reducing pigmentation and discoloration. It also stimulates the production of new cells, reducing the appearance of superficial fine lines and wrinkles. Layer 3 Stimulates collagen regeneration to lift elasticity and anti-wrinkle. Collagen loss is a major cause of sagging skin and wrinkles. Fruit acids penetrate deep into the skin to stimulate collagen regeneration in the dermis, effectively improving the elasticity and tone of the skin, making the skin firmer and improving deep wrinkles. Layer 4 Activates hyaluronic acid synthesis, moisturizing and nourishing. Hyaluronic acid (HA), another core component of the dermis, is also lost with age, causing skin dryness, dimpling and wrinkles. Fruit acids accelerate the production of mucopolysaccharides in the dermis to synthesize hyaluronic acid, which effectively improves the skin’s hydration capacity and doubles its moisturization. The choice of fruit acid products mild keratin The choice of fruit acid products should pay attention to the concentration, the concentration is too low keratin conditioning effect is not good, the concentration is too high and easy to hurt the skin. Experts suggest that you should go to a professional medical institution to choose a fruit acid peel. In the choice of home fruit acid products conditioning keratin, small beauty recommended cleansing + moisturizing products with the use, and it is best to choose a simple and effective formula, and the same acidic ingredients to complement the product, because only acid-acid combination, will not offset their respective effects, and acid-base combination, the results are either neutralized, or also add acid-base buffer, causing unnecessary burden to the skin.
