What Peptides does

Short chains of amino acids that signal skin to support collagen and repair. They are gentle, a good anti-ageing option for people who cannot tolerate retinoids, and they layer easily.

What Retinal does

Retinaldehyde is one conversion step closer to retinoic acid than retinol, so it works faster than retinol while usually being gentler than tretinoin. It also has a mild antibacterial effect useful for acne.

Frequently asked questions

Can I use Peptides and Retinal together?

Yes, it is safe. There is no known chemical conflict between Peptides and Retinal, and neither makes the other less effective. They share a goal (aging), so together they reinforce each other.

Which goes first, Peptides or Retinal?

Apply Peptides first, then Retinal. The general rule is thinnest to thickest texture, and lowest pH first.

Should I use Peptides in the morning or at night?

Peptides: works morning or night. Use morning and night after water-based serums. Low-pH acids applied at the same time can break some peptides down.
