NAD+ Retinal Serum.

"This has been around for like three years, but in the original form it was retinol as the key active, now it's retinal, one letter different but a game changer because retinal is much more effective than retinol and less sensitizing, so it's perfect for the under eye. It's got NAD, which is pro-collagen and helps with dark circles, and fifty different peptides which boost collagen and elastin production and plump out fine lines. The retinal over time boosts collagen to smooth everything out and eliminate crow's feet, it's a powerhouse. It used to come in a really clunky faux-needle style packaging which I hated, now it comes in a tube, so much better, better formulation, better ingredient profile and much better packaging. It went from an 8 out of 10 to a full 10 out of 10. Shop around because I've seen quite a variance in price and availability across sites. This is a great option if you're looking primarily for anti-aging, it's great for all round anti-aging. Absolutely love it."
