I'm 31. Live in a hot, windy, dry, high elevation desert climate with DRY winters and HOT summers. Aging from sun exposure is a concern. I have ridiculously sensitive skin bordering on very mild dermatitis. And, I love this product. It's a lot like a collagen essence and is EXACTLY what I wanted.
COOL THING ABOUT THIS - It contains palmitoyl tripeptide-1 which is a skin conditioning 3 amino acid peptide which tricks your skin into thinking collagen is breaking down and it needs to create new collagen. TRICK. YOUR. SKIN. It pays off.
PROS - super lightweight, good for layering in a routine; non-skin irritating; no fragrance; easy to mix with other products; VEGAN; affordable; makes you look less aged out and haggard (that's just me); good sized bottle.
CONS - oober lightweight, you may not like that. I'm not a fan of container, it's simple with a little snap open lid that gets a bit messy. Personally, I put mine in a small glass dropper bottle and am a much happier less wrinkled camper.
Hope that helps!
