Retinol has never been as popular in Korea as it is in western countries. And to get a little Carrie Bradshaw about it, I couldn’t help but wonder… if not retinol, then what?
Make no mistake: retinol exists in K-beauty (in 2025 more than ever) but Korea was a much later adopter than the West. Instead, Koreans have long-since championed low-irritation, MFDS-recognized wrinkle-care ingredients like adenosine and niacinamide rather than higher-strength actives.
While retinol is no longer as rare in Korea as it once was, the local approach does still prioritise skin barrier support and soothing co-actives, with retinols available at a range of strengths.
If retinol doesn’t work for you for whatever reason OR you’re just after some other options, below we’ll explore some of the Korean go-tos you can sub in (or pair) with retinol. Think of it like choosing between Aidan’s dependable Golden Retriever vibes vs Big’s drama: both can work, but timing and tolerance matter.
Collagen (Topical for comfort & bounce)
Topical collagen hydrates and gives an instant “bouncy” feel, which is great for drier and more mature skin. It doesn’t replace vitamin A/C for remodeling, but it’s a comforting layer in a well-aging routine.
Note: Topical collagen does not replace your skin’s intrinsic collagen. Because native collagen molecules are large, topical formats mainly support the surface—helping with hydration and reducing transepidermal water loss.
Vitamin C (brightening & firmness)
Vitamin C is well-regarded as a powerful antioxidant for well-aging in Korea. Not only can it help the appearance of uneven tone, it also supports collagen. In fact, some Korean researchers even believe Vitamin C is the key to barrier recovery, and that skin with a lower pH is associated with faster barrier repair. The trick however is to find a stable formula that works well for your skin and layer it under SPF for complementary photoprotection. Some people find that high-strength Vitamin C irritates their skin, so if that's you try and stick to 5% or under.
Niacinamide (the K-beauty workhorse)
Some people complain that its almost impossible to find Korean beauty products without niacinamide (and if that's you, we've got you). But there's a very good reason for that. Not only is it recognised as a functional cosmetic ingredient by Korea's MFDS (if used at approved levels), with benefits like balancing, brightening, minimising visible pores and calming who wouldn't want it in their routine? You’ll find a functional amount of niacinamide in:
Peptides (signal & support)
Short chains that help with a firmer, bouncier-looking complexion. Korea often combines peptide complexes with humectants for cushiony textures.
Adenosine (MFDS-recognized wrinkle-care)
Adenosine is a long-standing K-beauty favorite for everyday, low-irritation wrinkle care. In cosmetics, it’s used to help skin look smoother and more refined. It's so effective that it is recognised as a functional cosmetic ingredient for wrinkle care by Korea's MFDS. It is acknowledged to:
- Help improve the appearance of fine lines and wrinkles
- Support a more refined, supple look
- Pair well with barrier-supporting routines. It's commonly used alongside niacinamide, humectants and emollients for everyday wear.
