On the principle of using fruit acid and salicylic acid together
The principle of skin care is that if you want to be smooth, delicate, transparent and flawless, you often rely on various skin care methods. Among them, the use of fruit acid and salicylic acid is quite crucial, but the rule of using both cannot be ignored.

Fruit acid has the power of exfoliating, which can make the old and waste exfoliation on the surface of the skin fall off, make the skin renewed, more uniform in color, and can stimulate the production of collagen in the dermis, and increase the elasticity and luster of the skin. Salicylic acid is good at penetrating deep into the pores, dissolving oils, and clearing blockages. It is especially effective for skin problems such as acne and acne. It can also resist inflammation and relieve skin inflammation.

If you want to use both fruit acid and salicylic acid, you should first be cautious. The tolerance of the skin varies from person to person. When using it for the first time, it is advisable to start with a low concentration. Take fruit acid as an example. The concentration can be found to be about 5%. After a few days, wait for the skin to get used to it, and then try to increase the amount. The same is true for salicylic acid. It is appropriate to initially choose a concentration of 0.5% - 1%. When applying, the method should be gentle and evenly applied to the face, avoiding sensitive areas such as the eyes and lips.

Furthermore, the timing of use should also be paid attention to. The two can be used together, and it can be carried out at night. Because the skin's metabolism is strong at night, it is more conducive to absorption and repair. And you need to pay attention to sun protection during the day. Both can make the skin more sensitive to ultraviolet rays. If there is no protection, it is easy to cause tanning and sunburn.

The skin may react after use. If you only feel slight tingling and redness, this is a sign of skin adaptation. You can apply a cold compress to relieve symptoms, and then use it to prolong the interval appropriately. If the reaction is severe, such as redness, swelling, itching, severe desquamation, etc., stop using it immediately and seek medical attention.

In short, the combination of fruit acid and salicylic acid needs to be used step by step, with the tolerance of the skin as the degree, and with caution, in order to achieve the beauty of skin care and achieve the transformation of the skin.
