Moisture barrier saving grace!!

I ruined my skin 2ish years ago from misinformation and over exfoliation. I had skin so dry that it felt like it would peel if I smiled. Since using this in my regimen regularly, my skin has significantly gotten brighter, it’s hydrated, and it’s great for those who have sensitive skin such as me. Skin is so supple, the product has been so effective that I think it’s worth every penny.

FAB for mature skin!

Love love LOVE this product. In my late 60's now, my term recommended I find serum with hyaluronic acid listed among the first few ingredients. After searching dozens of brands/ingredients this was the only one with HA listed in the first sentence of ingredients. I've now been using for over a year and constantly get compliments on my skin/complexion. Not heavily scented and honestly I had to get used to the particular scent of this...but WELL WORTH IT FO THE RESULTS.
