is it bad to not use it? the problem is many of moisturizer would make me get acne like a teen. I'm 24 by the way. I tried Garnier, biore, and other local products. and those made me have acne. by the way I didn't change the products often. I just used a moisturizer a few times, and then I stopped using any moisturizer for a few months until I found other moisturizer that I want to try..
