I broke out a little bit….

Well it is my time of the month right now, and think that might be why I broke out a bit on my chin and cheeks. It’s not bad, just groups of small bumps.
I have SUPER sensitive skin by the way. Here is what I use nightly:
Almay Cleansing Lotion For normal skin, Noxzema Skin Cream, and a dermatologist acne gel.
