When I want to mess around with smells, I try a variety of essential oils. Lavender oil works really well and gets me lots of compliments from people who think it's my perfume. Orange oil works okay-- not bad at all but not as strong and long lasting. I've tried less flowery ones for when I've been sick and so didn't mind smelling strongly herbal. I would just say to be careful and make sure you're not applying something like basil essential oil full strength since that would burn. See what is okay straight, or add to your baking soda or coconut oil, and spot test. I use it straight just fine but I've also used these in other applications so I know what my personal skin to essential oil level I'm comfortable with.
I'll likely use up my 10% glycolic acid stuff and then eventually get a $25 bottle of 20% glycolic acid and use that once a week or so. Since it's an acid, I wouldn't recommend using it everyday or even close to that--maybe twice a week tops.
