Beauty Tips For Body Care
What's my miracle cure? I've read that a glycolic acid product could work well. I've used REN Glycol Lactic Radiance Renewal Mask and it's seemed to be a very temporary aid. I'm also considering microdermabrasion to get rolling on a better routine. Advice please!Also, I'm going to South Korea soon, any suggestions on what products should I buy there? (Doesn't necessarily have to be related to above question)
