That's quite a bit of comedonal acne. If it's really that irregular for you to breakout like this, my thoughts are that it has to do with the allergic reaction and subsequent Desonide cream. The allergic reaction could have really helped clear your follicles as it seemed to have induced an exfoliant effect (Like a chemical peel). This essentially reset your pores, which was great for a couple weeks. Then you applied the comedogenic Desonide cream all over your face, consistently for 2 weeks. Now with all of your pores clear from the peeling, this led to a hyper-breakout all over your skin, of non-inflammatory acne (whiteheads, in your case).
A couple of things to consider:
- Read the side-effects/ingredients of anything you put on your face. Mild side effects of Desonide cream include breaking out.
- Stop using the Desonide cream immediately, start using some benzoyl peroxide once/twice a day
- Wait it out, it may take a while for this to totally go away, but you'll get through it.
Good luck and don't pick!!
