Please stop using Melrio cream immediately, as the redness and irritation indicate skin sensitivity or a mild chemical burn. Do not apply Betnovate-N cream to your face; it contains a strong steroid and antibiotic which can cause skin thinning, steroid acne, and worsen the irritation when used inappropriately. Instead, allow your skin to heal by using a gentle, fragrance-free cleanser and a soothing moisturizer containing ceramides or hyaluronic acid. Always apply a broad-spectrum SPF 30+ sunscreen during the day to protect the healing skin. Please consult a dermatologist for a proper assessment and a safer treatment plan for your dark spots.
