On the day when fruit acid takes effect
fruit acid, everyone has a certain period of effect on the skin. However, the number of days it takes effect is actually controlled by many factors.

First, it is related to the characteristics of the individual skin. For those with tender and sensitive skin, fruit acid may be effective quickly when used for the first time. Cover this kind of skin, the cell metabolism is relatively active, and fruit acid is involved, which is easy to promote its renewal. For those with rough skin and strong tolerance, it may take a little longer to see the work of fruit acid. Because of its thick stratum corneum of the skin, the penetration of fruit acid is slightly slow, but once it takes effect, the effect is also good.

Second, the concentration of fruit acid is greatly related. Low-concentration fruit acid, gently nourishing the skin, is often selected by those who use fruit acid for the first time. Although it is less irritating, it may take a long time to take effect. If a low-concentration fruit acid of 2% to 5% is applied to the skin, it may only feel slightly moist at first, and it may take two to three weeks to see a significant skin rejuvenation effect. High-concentration fruit acid has a strong effect, and it needs to be operated by professionals. If a high-concentration fruit acid of more than 20% is applied to suitable skin, within a week, it can be seen that the skin's luster will improve and fine lines will fade. However, such high-concentration fruit acids are also risky and should not be used by non-professionals.

Third, daily skin care is also related to the effect of fruit acid. If you pay attention to moisturizing and sun protection when using fruit acid to create a good environment for the skin, the power of fruit acid can be quickly demonstrated. On the contrary, if the skin is dehydrated and often exposed to ultraviolet light, the effect of fruit acid may be suppressed, and the onset time will be prolonged.

In general, the number of days when fruit acid takes effect, your mileage may vary, depending on the concentration, depending on skin care. It can take as little as a few days, as much as a few weeks. To get the good effect of fruit acid, when you use it carefully, choose the appropriate concentration according to your skin condition, and perform appropriate skin care, you can achieve the desired effect.
