Peptides in short
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.
Tretinoin in short
The prescription-strength retinoid, and the gold standard for acne and photo-ageing, with decades of evidence. It works directly (no conversion needed), so it is stronger and more irritating than retinol or retinal.
