Can a serum with vitamin C be used while using Tetralysal?

Yes, you can. Using vitamin C serum in combination with Tetralysal is generally considered safe because vitamin C is an ingredient that can help improve skin condition and is used in many skin care products.

Vitamin C is known for its antioxidant effect and ability to improve collagen in the skin, which can help reduce acne scars and discoloration. However, to avoid possible allergic reactions or irritation, I encourage you to carry out a skin reaction test for the new product. This can be done by applying a small amount of the serum to a small area of skin (e.g. on the wrist) and observing for a few days for adverse reactions such as redness, itching or burning.

Please also remember to exercise caution when using skin care products when treating acne. Please avoid aggressive treatments or products that may irritate the skin, as the skin may be more sensitive when using antibiotics.

If you have doubts or concerns about the use of vitamin C serum in combination with Tetralysal, it is worth consulting a dermatologist. If you are not able to take advantage of the advice, I enclose a link to online teleadvice, e.g. via the Gdziepolek.pl portal:
