[PSA] If you tear a callous while lifting, be super careful with your Niacinamide!

Beauty Tips For Body Care
Tore a callous while doing deadlifts and forgot all about it while I was running through my routine in the evening. At least I forgot about it until I reached my TO Niacinamide + Zinc. Holy mother of ouch! I thought it stung when it went over any broken skin on my face... I knew nothing of stinging!
