It has a professional saying: chemical peels. Need to go to a hospital/professional institution to be operated by professionals.
Chemical peels can be divided into very shallow, shallow, medium and deep peeling according to the depth of peeling. The most commonly used exfoliants for chemical peels are fruit acids (alpha-hydroxy acids, AHA) and salicylic acids (beta-hydroxy acids, BHA).
You’ve probably heard of salicylic acid countless times, but many people still don’t understand it. Let’s talk about it today.
1.For acne
Salicylic acid is an exfoliative drug that is lipophilic. It can penetrate the hair follicles and sebaceous glands to achieve the effect of dissolving acne. Can effectively treat acne. Salicylic acid is also an option for those who cannot tolerate tretinoin or benzoyl peroxide.
Of course, salicylic acid can also be used in combination with benzoyl peroxide, an antibacterial drug. Because they play complementary roles in the mechanism of acne treatment.
2.For post-inflammatory hyperpigmentation
Post-inflammatory hyperpigmentation (PIH) is a common condition that includes problems such as acne marks and melasma.
Clinically, chemical peeling usually uses salicylic acid at a concentration of 20% to 30% (requires professional operation). Controls exfoliation of epidermal keratinocytes to accelerate melanin excretion. Improves pigmentation to remove acne marks and blemishes.
Since superficial chemical peels are well tolerated by most patients, this approach is a good option for the treatment of PIH. However, strict sun protection before and after treatment is important to reduce the risk of adverse postoperative effects.
3.Other functions
In addition, salicylic acid also has a certain improvement effect on rosacea (rosacea), solar lentigo, and mild to moderate photoaging. All in all, salicylic acid is a treasure as long as it is used well.
However, even if the peeling effect of salicylic acid is good, it needs to be treated according to the diagnosis and recommendation of the doctor. Don’t do it yourself at home. Improper use will lead to a bad complexion and even disfigurement.
