10 most popular skin care acids you should update right away
Among about 30 skin care acids, glycolic acid is the most common form and is recommended by doctors for those who have never tried acid in facial skin care. Glycolic acid is a small molecule of AHA that helps reverse the signs of aging, balance collagen and improve uneven skin tone.
The second most common type after glycolic acid is salicylic acid, a member of the BHA group that is very effective in treating acne. Salicylic acid penetrates into the skin to cleanse the pores, preventing acne from multiplying. You can choose salicylic acid if you want the pores to shrink.
Hyaluronic acid is a very effective moisturizer thanks to the ability to keep water 1,000 times its own density. By the age of adulthood, the amount of natural hyaluronic acid in our body decreases, leading to aging and less healthy skin. Therefore, hyaluronic acid is not only good in moisturizing but also a way to keep youthful.
Lactic acid also belongs to the AHA group as glycolic acid and has the same yet less effective effect. Often, lactic acid is found in common with other skin-nourishing acids in many products. However, for this reason lactic acid is a safe choice for sensitive skin.
Kojic acid is prepared from mushrooms or appears in the fermentation of fermented rice and sake. This acid inhibits the production of melanin, which causes dark spots. Kojic acid is a more recommended ingredient than hydroquinone, another active ingredient that has similar effects but is more active and should not be applied on sensitive skin.
Found in cereal cells and seeds of some fruits, ferullic acid is a skin-nourishing acid that helps reverse the signs of aging by preventing free radicals from being broken down by sunlight and by impacts from the environment. In addition, ferulic acid will be better if used together with other antioxidants such as vitamin C and vitamin E.
Azelaic acid is also capable of exfoliating as the AHA and BHA acids, but the effect is somewhat even better than those two. Besides the ability to clear pores, acne and dark spots, azelaic acid improves the skin surface very well. In addition, sensitive skin after taking azelaic acid for a while will be stronger with less risk of irritation when using cosmetics.
Derived from almonds, mandelic acid is a skin acid in the AHA group with strong antioxidant effect. Like glycolic and lactic acid, mandelic acid also improves skin texture. In addition, this acid clears sebum and acne due to its ability to dissolve well in oil.
Retinoic acid is an acid that has been transformed from active antioxidant the retinol. This transformation helps retinoic acid work better on the skin surface, dramatically improving the signs of aging skin. Dermatologists recommend starting using retinoic acid before reaching the age of 30.
Linoleic acid is a fatty acid found in many vegetable oils. The main effect of this acid is healing and fighting inflammatory, maintaining the normal development of skin cells. Therefore, the use of oils containing linoleic acid as primrose oil, cactus seed oil, argan oil, rosehip oil... can also support the treatment of acne.
