On the matter of applying moisturizer before using fruit acid
In the way of skin care, people have different opinions on applying moisturizer before applying fruit acid.

Or you can apply moisturizer first. Those who cover moisturizer can moisturize the skin, make it smooth, and slow down the dry state of the skin. Applying it before using fruit acid can form a protective film on the surface of the skin to reduce the irritation of fruit acid to the skin. For those with delicate skin, or those who use fruit acid for the first time and are not resistant to its irritation, apply moisturizer first, just like building a barrier to protect the skin from the irritation of fruit acid, which can prevent skin discomfort, such as redness and tingling.

Of course, it is also said that it is impossible. The properties of fruit acid can exfoliate, clear the old and waste exfoliation of the skin, and promote the metabolism of the skin. If a moisturizer is used first, its ingredients may form a film on the surface of the skin to prevent the fruit acid from fully contacting the skin and reduce the effect of fruit acid. If you want to achieve the effect of fruit acid rejuvenating and brightening the skin, this barrier may become an obstacle, so that fruit acid cannot do its best.

It stands to reason that if the skin is well tolerated and wants the maximum effect of fruit acid, you should not apply a moisturizer first; if the skin is sensitive, it is also a good strategy to apply a moisturizer to prevent excessive irritation. Users should weigh the advantages and disadvantages according to their own skin conditions and choose the most suitable method to achieve the best skin care.
