For safe and effective use of exfoliants, it is important to gradually introduce them into your daily care routine. Start with low concentrations and use the products 1-2 times a week, gradually increasing the frequency if necessary. Pay attention to skin reactions and avoid overuse to prevent irritation. It is also important to apply sunscreen every morning, as exfoliating acids increase the skin's sensitivity to UV radiation. Combining different types of acids can be beneficial, but always consult a dermatologist or esthetician before starting a new treatment.
