On the burning sensation of fruit acid and niacinamide
The feeling of the skin is related to the things used. Since modern times, fruit acid (Glycolic Acid) and niacinamide (Niacinamide) have been used in skin care products, but sometimes users feel the burning of the skin.

Fruit acid has the power of rejuvenating the skin, can exfoliate, promote skin metabolism, and make the skin glow. Niacinamide can inhibit melanin transport, brighten the skin and shrink pores, and is also a good choice for skin care. The combination of the two has a synergistic effect.

However, it can be used in combination to generate a burning sensation. Why? The acid of the cover fruit is strong, which can cause short damage to the skin barrier and make the skin sensitive but intolerant. Although nicotinamide is mild, it may cause discomfort when the skin is damaged. And the combination of the two is applied, or it may increase the irritation to the skin and cause burning.

To solve this dilemma, it should be done step by step. Use low-concentration fruit acid or nicotinamide products first, and wait for the skin to adapt, and then increase the concentration. And you can do a skin test before use, and apply a small amount in the wrist or behind the ear to see if it is uncomfortable. When using, it is also advisable to avoid sensitive areas such as the eye area and the mouth area. If the burning sensation is severe, stop using it immediately, wash the skin with water, and consult a doctor if necessary.

In general, the way of skin care is to know the nature of the skin, choose the products that suit you, and gradually protect the health of the skin and avoid burning.
