Hello and welcome to healthcaremagic If I was the treating doctor I would suggest that you use a gel based sunscreen, that which offers both UV A and UV B protection, throughout the day. Once daily azaleic acid cream can be used at night, at the start of therapy. Azaleic acid works for both acne and pigmentation. Other skin lightening ingredients that are effective for post acne hyperpigmentation are kojic acid, glycolic acid, hydroquinone etc Elocon is a steroid and should not be used on face for long since it can itself cause acne. regards
