On the compatibility of fruit acid and niacinamide
The way of skin care, the combination of ingredients, is related to efficacy and skin feel, and cannot be ignored. Today, there are glycolic acid and niacinamide, both of which have attracted much attention in the skin care industry, but whether they can be mixed and used, there are different opinions, and it is necessary to study in detail.

Fruit acid has the ability to exfoliate, which can make the old and waste exfoliation on the surface of the skin fall off, rejuvenate, make the skin delicate and smooth, and can promote the metabolism of the skin and improve the absorption of subsequent skin care products. Niacinamide can regulate oil secretion, improve skin dullness, brighten skin tone, and maintain skin stability.

However, the two are mixed, and the advantages and disadvantages coexist. In theory, fruit acid is acidic, and niacinamide may undergo a hydrolysis reaction in an acidic environment to generate niacin. Niacin not only stimulates the skin, but also loses the skin care effect of niacinamide. If the two are mixed in an improper ratio, the concentration of acid is too high, and the effect of niacinamide may make the skin intolerant, resulting in redness, tingling, itching and other uncomfortable symptoms.

However, there are also opinions that if properly blended, the two can also work together. For example, low-concentration fruit acid is mixed with niacinamide, which promotes skin metabolism, and niacinamide strengthens the skin barrier, or can improve skin quality while maintaining skin stability. And with the development of modern technology, the formula process is becoming more and more perfect, and some products have been specially treated to ensure that the two can coexist stably.

Therefore, if you want to mix ordinary fruit acid with nicotinamide, you must be cautious. First of all, if you want to carefully observe the skin type and sensitive skin, you should try it on a small scale before local skin to observe its reaction. If there is no discomfort, you can gradually expand the use area. In addition, you need to control the mixing ratio, starting from a low concentration and gradually. And during use, pay close attention to the skin condition, and stop using it immediately if there is any discomfort.

In short, skin care should be based on scientific understanding and your own skin type, and the mixture of ingredients should be carefully treated to achieve safe and effective skin care purposes.
