Rosacnil Gel is usually prescribed for acne and post‑acne marks. However, if your skin is already sensitive, showing redness and heat, it is not advisable to start this gel on your own. Sensitive, inflamed skin can react strongly to acne treatments, leading to more irritation or worsening redness. The safest step is to consult a dermatologist, who can examine your skin, confirm whether Rosacnil is suitable, and guide you on the correct way to use it, or suggest gentler alternatives if needed.
