Hello ..Thanks for your query.
You have used a steroid on face for long.there are several side effects like:
1)Skin Atrophy: thinning of the epidermis
and changes in the connective tissue
of the dermis.
2)Hypopigmentation:lighter colored skin, giving a sense of skin becoming clearer.
3)Acne resulting from steroid use continuously.
Most of these are reversible by stopping the application which you have already done.But it requires sometime for the skin to come back to its normal form.
If you see a lot of whiteheads/blackheads ,as is common on use of steroid ,it is best to get it extracted by a dermatologist
.Else ,they take long to heal and the scars are bothersome.You can start with application of Clindamycin
gel twice daily on face .Do not use Retinoids
at this stage on your face as they might cause skin irritation and dryness.Do not touch or attempt to squeeze out pimples as they will aggravate scarring.
Hope this helps.Take care!
