Hello. Thank you for writing to us.
I will keep a possibility of
Pityriasis alba. Patches of Pityriasis Alba are common on dry skin.
First of all, I would like to assure you that Pityriasis Alba is not a serious condition. It is only of cosmetic concern.
These light colored patches can be somewhat scaly as well, the light color being actually due to
post-inflammatory hypopigmentation.
I usually recommend using a good moisturizer to may patients, to be applied once or twice daily, all over the face.
Avoid soaps. Rather use a gentle cleanser for face wash e.g
cetaphil cleansing lotion, twice daily.
You may also use an OTC
topical steroid e.g 1% Hydrocortisone twice daily, for patches, over and above moisturizer, for 3-4 weeks.
Alternatively a topical immunomodulator e.g tacrolimus 0.03% ointment works even better than 1%
hydrocortisone cream. Use it only over the patches.
Tacrolimus is a prescription drug and I suggest you to talk to your doctor for the needful.
The response usually takes 3-4 weeks to become evident.
Regards
