Rash on your face may be due to acne.
They have occurred since you have applied clobetasol
,humidus,sunscrren.All these causes blockage of ducts leading to acne.Do not apply anything on face now.
For dry skin
use a good moisturizing soap like dove.You also need to apply a good moisturizer on face which is non comedogenic and a mild steroid like hydrocortisone
You can continue treatment with antioxidants and teczine.You can also apply clindamycin
gel over face for few days .
I hope this will solve your problem.Take care.
