Is the product suitable for sensitive skin, and how can you check your reaction before first use? — Cosmetic product "Altai Celandine", 1.5 ml - MedicalFort

The formula contains celandine extract and alkaline components to adjust the pH — both ingredients have a pronounced local effect on the keratinised layer, so for thin, easily irritated skin such a product calls for particular caution. The manufacturer expressly states that a sensitivity test is needed before first use.

The standard approach: apply a minimal amount of the product to a small area of hardened skin and leave it on for the time stated in the instructions. Then rinse it off and watch for a reaction over 24 hours. If severe burning, swelling or redness spreading beyond the treated area appears, this is a sign that the product is not suitable for you.

Slight tingling directly on the hardened area during exposure is considered an expected reaction for products of this type, but intense pain or a reaction on healthy skin is a reason to stop using it. During pregnancy, for children or if you have a history of skin conditions, consult a dermatologist before use.
