I've been enjoying using this product. I use it as my 5th step, after using an ampoule and before using a sheet mask. This is light weight enough to use as a moisturizer in spring and summer, and use as a serum in the fall and winter. 3 drops of this is enough for the full face. Also this product is fragrance free, which I like. The only thing I don't like is when putting the glass dropper back into the bottle, the product bubbles out and creates a mess. Other than that, its a 5/5. Would recommend.
