Retinal
also known as Retinaldehyde, retinol
The fastest-acting OTC retinoid — smooths lines, evens tone, and unclogs pores with less irritation than retinol.
What it is
The aldehyde form of vitamin A. One conversion step from retinoic acid (tretinoin), which makes it more potent than retinol but gentler than prescription retinoids.
What it actually does
Retinoids speed up cell turnover, increase collagen production, and normalize how your pores shed dead cells. Your skin has to convert each retinoid up the chain — retinyl ester → retinol → retinal → retinoic acid (the active form). Retinal is one step from active, so it works faster than retinol with comparable irritation. Korean formulas tend to encapsulate it for stability and tolerance.
Why K-beauty uses it
Korean retinal formulas (Medicube, Numbuzin, Beauty of Joseon) are usually encapsulated at 0.05–0.1% — lower on paper than Western retinol serums, but often better tolerated at the same visible effect.

Use with care
Not "avoid at all costs" — most K-beauty routines get away with these combos by splitting AM/PM or alternating nights. The caution is about how you layer, not whether you use them.
Routine placement
- Where it lives
- Serum
- AM/PM
- PM
- Frequency
- Every 3rd night → nightly
Pregnancy note: Avoid during pregnancy and breastfeeding. Use bakuchiol instead.
How to use it
Evening only, on dry skin, after cleansing — a pea-sized amount for the whole face. Always pair with daily SPF in the morning; without it you're moving backwards.
The Plug verdict
The best value in anti-aging right now. Korean encapsulated retinal at 0.1% out-performs most Western 0.5% retinols on tolerance.
