On the Timing of Using Fruit Acid
Fruit acid is used in the way of skin care and at the right time, and the effect is very different. Knowing when is appropriate can make good use of its effect and avoid its drawbacks.

In the morning, the sun is gradually rising, and the skin needs to resist external evil. Fruit acid has the ability to exfoliate, but it is used in the morning. After the skin is acted on by fruit acid, the stratum corneum becomes thinner and its resistance to ultraviolet rays decreases. If you go out and expose to sunlight during the day, it is easy to cause sunburn, tanning, and even induce skin inflammation. Therefore, it is not best to use fruit acid in the morning.

When night falls, the skin's metabolism becomes active. At this time, using fruit acid can, firstly, take advantage of the metabolism trend to help fruit acid penetrate deep into the skin and exert its effect of improving keratin metabolism, so that the waste keratin falls off smoothly, and the skin is rejuvenated and rejuvenated; secondly, there is no sunlight intrusion at night, avoiding the risk of skin photosensitivity caused by fruit acid. And after fruit acid care, adequate rest at night can allow the skin to better repair and adjust. It is a good time to use fruit acid at dusk.

At the same time as the skin state is different, the timing of fruit acid use is also different. If the skin is in the acute stage of allergies and inflammation, redness, swelling, itching, and tingling are obvious. At this time, the skin barrier is damaged and the tolerance is poor. The stimulation of fruit acid is like adding cream to the snow, aggravating skin discomfort and delaying recovery. Only when the skin inflammation has subsided and the condition is stable can it be used with caution.

As for dry skin, it is easy to lack water and dry every day, and the stratum corneum is often fragile. When using fruit acid, it is advisable to choose the one with low concentration, and the interval is slightly longer, such as once a week or once every two weeks. Due to high concentration or frequent use, it is easy to exfoliate excessively, resulting in increased moisture loss and drier skin. For oily skin, oil secretion is strong, and keratin accumulation is very high. The frequency of fruit acid use can be appropriately increased, such as twice a week, but it also needs to be adjusted according to skin tolerance.

In general, the timing of using fruit acid needs to be clear, depending on day and night changes, skin condition and skin type differences. In this way, the fruit acid can be used for skin maintenance, achieving twice the result with half the effort, and achieving skin moisturization, smoothness and health.
