Use sunscreen daily; a broad-spectrum SPF 30â50, fragrance-free and moisturising, is suitable for dry skin, with reapplication outdoors. Apply the prescribed cream only as a thin layer to the marks, not over a large area. Red blisters suggest irritation or allergyâstop it until your dermatologist reviews it, and do not apply on broken skin. Moisturise regularly and avoid picking or scrubbing.
Next Steps
Please contact the prescribing dermatologist about the blisters before restarting the cream. You may also book a consultation with me on Practo if the irritation persists or the pigmentation is spreading.
