On the impact of daily application of fruit acid
Fruit acid has attracted much attention in the way of skin care. However, if fruit acid is applied daily, the advantages and disadvantages of its effects are mutually apparent, and it cannot be ignored.

Daily use of fruit acid, the first to bear the brunt, is the change of the stratum corneum. Fruit acid has the ability to exfoliate. If it is done every day, the skin can be seen to be rejuvenated and brightened in the short term. Due to the rapid removal of old and waste exfoliation on the surface, the skin is temporarily tender. However, in the long run, the stratum corneum may become thinner. The stratum corneum is also the barrier of the skin. If it is thin, the skin's ability to resist external evil will decrease, and it will be easily disturbed by external stimuli, such as wind blowing, sun exposure, dust haze, etc., which can cause sensitive skin, redness, itching or present.

Skin hydration is also affected by it. Moderate application of fruit acid can increase skin hydration and moisturize the skin. However, when used daily, the skin is overhydrated, the intercellular space or disorder, and the loss of moisture increases, resulting in dry skin. And excessive hydration may damage the normal metabolism of the skin, imbalance of oil secretion, drier dry skin, and oily skin is prone to acne.

Furthermore, the skin's immunity and repair function are related to the daily application of fruit acid. In the early stage, fruit acid stimulation can promote the skin's metabolism and stimulate the repair mechanism. However, frequent stimulation, immune cells are tired of responding, and the repair ability is gradually weakened. Once the skin is damaged, it is difficult to repair in time, inflammation breeds, and skin problems multiply.

In summary, although daily application of fruit acid has short-term benefits, its potential drawbacks should not be underestimated. For long-term skin health, the application of fruit acid should be done with caution. According to skin characteristics, tolerance, and reasonable planning of frequency and dosage, it is the best policy to maintain the skin.
