Thanks for the query. Allergic contact dermatitis is a common problem with people who have sensitive skin. New product can cause problems and should be used after applying it in small quantities on the forearm for few days and deciding if any allergies are developing to it. For the present problem, use OTC anti-allergic medications and consider seeing a Dermatologist for better diagnosis and treatment. Hope it helps. Dr MK Agarwala Dermatologist New Delhi
