Medical Grade Skin Care:  what does it actually mean??  

Medical grade products are different as they contain much higher doses of "active ingredients" such as biologically active Vitamin A and antioxidants like Vitamin C, which make "changes" in your skin.  In order to make changes in skin we need to slough off the outer surface to get to new skin.  Some products are more aggressive than others, but the bottom line is to keep skin exfoliated so product can penetrate and do their job.
