stars plus [SEP] i purchased aurora cure pure hyaluronic acid serum because i am currently testing out alot of different vitamin c serums to see which ones work the best what i have discovered is that most all of them tend to dry out your skin when you use them on a regular basis when you combine hyaluronic acid serum along with your vitamin c serum it is like your skin is getting radiant hydration from one bottle your skin feels so soft moisturized i love the fact that hyaluronic acid also aids in smoothing out diminishing fine lines wrinkles i love aurora skin care products
