Glycolic acid is one of the most preferred and effective AHA (alpha hydroxy acid) types in skin care. It supports skin renewal by gently peeling dead skin cells, cleans pores, reduces blackhead formation and provides a smoother skin texture. It plays an important role in equalizing skin tone, lightening acne scars and eliminating blemishes. When serum, tonic and peeling products containing glycolic acid are used regularly, the skin brightens and gains a more vibrant appearance. It is also effective in anti-aging care by reducing the appearance of fine lines and wrinkles. It is quite suitable for combination skin, oily skin and acne-prone skin types thanks to its pore tightening and sebum balancing properties. Glycolic acid peeling accelerates cell renewal when applied 1-2 times a week. The effect of the skin care routine increases when used with ingredients such as vitamin C, niacinamide and hyaluronic acid. However, since it can increase skin sensitivity, it should definitely be supported with sunscreen. Glycolic acid targets many problems such as acne, blemishes, dullness and skin tone inequalities with its skin rejuvenating effect. The best glycolic acid products should generally be selected with the advice of a dermatologist. For those who do their skin care at home, glycolic acid toners and serums offer effective and practical solutions. Glycolic acid is an indispensable ingredient for those looking for effective content in skin care.
