On the effect of benzoyl peroxide and glycolic acid
There are two substances today, called benzoyl peroxide (Benzoyl Peroxide) and glycolic acid (Glycolic Acid), which have their own abilities in the treatment of the skin, and are often discussed by doctors and beauty lovers.

Benzoyl peroxide has strong oxidative properties. It has significant effect on acne. When acne is covered, it is mostly due to the blockage of the sebaceous glands of the hair follicle, and the growth of propionibacterium. Peroxybenzoyl can break the wall of this bacterium, kill its reproduction, and can solve the plug of the hair follicle mouth, so that the sebum flows smoothly, so it can relieve the redness, swelling and papules of acne. However, its nature is strong, if used improperly, the skin may feel dry, desquamation, and tingling, especially for sensitive skin, so be careful.

Glycolic acid is a fruit acid and the like. Its molecules are small and can quickly penetrate the surface of the skin. It can loosen the connection between keratinocytes, make old waste keratin fall off, make the skin smooth and delicate, and have a uniform color. And it can promote the production of collagen in the dermis, increase the elasticity of the skin, and reduce the appearance of wrinkles. However, when first used, the skin may have a short-term itching and redness, and excessive use will also damage the skin barrier.

If compared with the two, benzoyl peroxide is highly targeted in the treatment of acne and can see its effect immediately; glycolic acid is more effective in the overall quality of the skin, such as whitening and anti-aging. Each has its own strengths and disadvantages. Users should choose the right one according to the nature of their own skin, or according to the doctor's advice, in order to achieve the best state of skin care and avoid the risk of skin damage.
