"On whether glycolic acid and nicotinamide can be shared"

In recent times, the way of skin care has attracted much attention, and the combination of many skin care ingredients has also become a hot topic. Among them, the combination of glycolic acid and nicotinamide has different opinions.

Glycolic acid is a fruit acid, which has the effect of promoting the renewal of the stratum corneum, improving the roughness and dullness of the skin, and making the skin more delicate and shiny. Niacinamide can effectively improve the skin barrier function, reduce skin moisture loss, and has a considerable effect on inhibiting melanin production and even skin tone.

However, the combination of the two needs to be treated with caution. Glycolic acid is acidic, and niacinamide may react under specific acidic conditions to produce niacin, niacin may cause skin discomfort, such as redness, tingling and other allergic symptoms.

Therefore, if you want to use glycolic acid and niacinamide in combination, you should first check your own skin tolerance. Those with strong skin tolerance may be tried in a small range and at a low concentration. If the skin has no adverse reactions, you can gradually increase the scope and concentration of use. For sensitive skin, in order to avoid skin damage, you should make a prudent choice or consult a professional skin care professional for advice.

In summary, the combination of skin care ingredients is related to skin health. If used properly, it will beautify the skin and nourish the face; if used inadvertently, it will be counterproductive. It is necessary to choose skin care products scientifically and rationally according to your own skin characteristics to achieve the ideal skin care effect.
