PCA SKIN Intensive Anti-Aging Retinol Serum 0.5% - Pure Retinol Face Treatment for Fine Lines & Wrinkles - 1 fl oz - Dermatologist Recommended for Nighttime Skin Renewal

I'll be 40 this year I'm seeing the beginning signs of aging, specifically wrinkling/sagging btwn my brows. I usually get botox but that doesn't really fix the problem. I used this product 5 years ago and remember it working magically. I bought it again, but hesitated btwn this and HA. Well, after only 3 applications, I can honestly say I see a difference. Yes, it is expensive, BUT IT WORKS (for me) I am partial to PCA brand to begin with but I think this is my new, regular skin care purchase product.
