Although these substances can complete the above functions, the chemical synthetic substances and preservatives they use have strong effects on the skin. Irritant, prone to adverse reactions such as allergies, and worsen damaged skin conditions, may also make consumers dependent on the product, long-term use may even affect the user's hormone secretion, and then damage the user's health
Due to the limitation of the anti-acne repair efficacy evaluation method, the existing anti-acne repair products also generally have limitations in the anti-acne repair function
