There are many opinions on the combination of fruit acid and glycolic acid
, and the combination of fruit acid (AHA) and glycolic acid. If you want to understand the reason, you should study its properties and uses in detail.

Fruit acid, a general term for a family of acidic compounds, originates from natural fruits, and has a wide range of types and characteristics. Glycolic acid, a genus of fruit acid, has the characteristics of small molecules and can quickly penetrate the surface of the skin.

The consideration of mixed use is first in the skin's tolerance. Both have the ability to exfoliate, and if used together, it will increase the strength. However, for those with delicate skin, if you use this mixture suddenly, you may experience discomfort, such as redness, tingling, and desquamation. Therefore, before using it, you should conduct a skin test. Take a little mixture, apply it to the wrist or behind the ear, and wait for two or three days. If there is no abnormality, it can be used on the face and neck.

Furthermore, the concentration is required. Low concentration can gradually start the process of skin adaptation; high concentration, although the effect is obvious, the risk is also high. For beginners, choose a low concentration, and wait for the skin to get used to it, and then increase the concentration. And the concentration of mixed use should be lower than that of single use to ensure skin safety.

The order of use is also exquisite. After cleansing, moisturize it with toner to hydrate the skin. Next, take the mixture and apply it lightly to the face to avoid the eyes and lips. If you feel unwell, wash it with water as soon as possible.

As for the frequency, it should be sparse for the first time, once or twice a week. When the skin tolerates it, it can be gradually increased to three or four times. However, it should not be too frequent, so as to avoid damage to the skin barrier, water loss, and allergies.

To sum up, if fruit acid is mixed with glycolic acid, if it is used according to the quality of the skin, and the concentration, duration, and frequency of use are observed, it can rejuvenate the skin, making the skin smooth and shiny. If it is not used with caution, the harm will outweigh the benefit. It is the user who should be careful and act according to the rules to obtain the benefits of skin beauty.
