On the frequency of use of common fruit acid
For fruit acid, it is also a common ingredient in skin care. However, the frequency of use is related to the adaptation and efficacy of the skin, which cannot be ignored.

For those who use fruit acid for the first time, the skin is delicate and weakly tolerated. It is advisable to start with a low frequency, such as once every seven days. It is necessary to adapt to the stimulation of fruit acid when covering the skin. If used rashly and frequently, it may cause skin discomfort, such as redness, itching, tingling, etc.

When the skin gradually adapts to fruit acid, the frequency can be increased according to the specific situation. If the skin is in good condition and well tolerated, it can be gradually adjusted to once every five days. At this point, the effect of fruit acid is gradually apparent, such as exfoliating the skin, making the skin smooth and delicate, and also helping to improve uneven skin tone.

However, even if the skin adapts well, do not use fruit acid too frequently. Excessive use may damage the skin barrier and reduce the skin's water retention ability, which can easily lead to dryness, sensitivity and other problems. Therefore, once every three days is almost the limit, and it is necessary to pay close attention to the skin's reaction.

Furthermore, different skin types have different tolerances to the frequency of fruit acid use. For oily skin, with strong sebum secretion, or more dry and sensitive skin, which can tolerate the stimulation of fruit acid, the frequency of use can be moderately higher; for sensitive skin, even after adaptation, it is recommended to maintain a lower frequency, such as once every six or seven days, to prevent allergic reactions.

In short, the frequency of use of ordinary fruit acid should be based on skin tolerance, step by step, and be cautious. In this way, the power of fruit acid can be used to achieve the best condition of skin care without the risk of damaging the skin.
