The Ordinary·Serum
See alternativesCopper-peptide anti-aging cocktail
- Key actives: Copper Peptides 1%
The why
A peptide serum with copper peptides, humectants, and allantoin for people chasing hydration, bounce, and fine-line support. Reddit mostly treats it as a long-game add-on; the sticky texture and occasional irritation make it a YMMV pick.
One minus
Sticky texture that can pill
Both recommended for Anti-Aging.
“The peptides might just help a lot with hydration, but I noticed more "bounce" to my skin after using that for several months, even when compared to retinoids.”

#3

- Key actives: Argireline Solution 10%
- Size: 30 ml
- Price per ml: $0.32/ml (original $0.41/ml)
The why
A watery peptide serum that people use on forehead, 11s, and crow’s feet. It suits folks chasing temporary softening or a stopgap before Botox. Don’t expect permanent wrinkle reversal, and some users break out.
One minus
Results are mostly temporary, not lasting
Both recommended for Anti-Aging.
“I use the ordinary matrixyl and argireline under my frownies and find that the combo works really well for my fine lines.”
