Combination application of nicotinamide and glycolic acid

There is a way of skin care in the world, which is related to the combination of ingredients. The combination of nicotinamide and glycolic acid is quite popular.

Niacinamide is also a good agent for skin care. Its mild nature can adjust the oil of the skin and make the skin even. And it can increase the toughness of the stratum corneum, protect the skin's barrier, and block external disturbances. It can also promote the production of collagen, slow down the aging of the skin, and make the skin firm and elastic.

Glycolic acid is a fruit acid and the like. Its molecules are tiny and can enter the deep layers of the skin, loosen the connection of keratinocytes, promote keratin renewal, and make the skin smooth and delicate. And it can increase the brightness of the skin, light pigmentation and dullness.

However, when the two are used in combination, be careful. The pH value of nicotinamide is alkaline, and glycolic acid is acidic. When mixed, it may cause a change in pH value, which affects the effect. And glycolic acid thins the stratum corneum of the skin and increases the sensitivity of the skin. If it is matched with nicotinamide, it may cause discomfort, such as redness, tingling, etc.

If you want to use a combination of these two ingredients, you should first test the tolerance of the skin. Take a small amount of the product containing these two ingredients and apply it behind the ear or on the inside of the forearm. After a few days, observe whether there is any adverse reaction. If not, it can be gradually used on the face. When using it for the first time, the frequency should be low, such as once or twice a week, and then it will gradually increase according to the skin's adaptation.

When using it, it should also be heavily protected from the sun. Glycolic acid makes the skin more sensitive to light. If it is not protected from the sun, it is easy to cause sunburn and pigmentation. It is advisable to use high-multiple sunscreens when going out, and physical sunscreen such as umbrellas and hats are also essential.

In short, the combination of nicotinamide and glycolic acid, if used properly, can bring many benefits to the skin. However, the way of skin care, your mileage may vary, you need to follow your own skin characteristics and be careful to achieve the desired effect.
