Your feed is full of K-beauty serums, pads and mists. Here are five worth a look, sorted by skin goal, not hype.
Some of these are strong actives, so how you use them matters as much as which one you pick. We haven't tested these hands-on. Picks are based on Amazon listings, brand info, published reporting and buyer reviews.
This is general info, not medical advice.
For redness and post-breakout marks, the Anua Azelaic Acid 10 serum is our pick. For fine lines, try the celimax Retinal Shot at night. For oily pores, the medicube Zero Pore Pad. Don't start them all at once.
Pick by skin goal
- Redness and marks: Anua Azelaic Acid 10
- Fine lines and texture: celimax Retinal Shot (night only)
- Oily skin and clogged pores: medicube Zero Pore Pad 2.0
- Instant glow: d'alba White Truffle First Spray Serum
- Calm, breakout-prone skin: Dr.Althea 345 Relief Cream
Why everyone's talking about them
Vogue named the celimax Retinal Shot the best Korean pick in its retinal serum roundup. LookFantastic's 2026 sales data put medicube's Zero Pore Pad 2.0 up about 920% year over year (published Oct 2026). And Olivia Culpo's makeup artist used the d'alba spray serum to prep her skin for the 2026 NFL Honors (per Page Six).
Don't start them all at once
Retinal, exfoliating acids and azelaic acid can all irritate, and stacking them is the fastest way to a red, flaky face. Add one new product every couple of weeks. Use retinal and the exfoliating pads on different nights, never together. If you use azelaic acid with retinal, try azelaic acid in the morning and retinal at night. Wear SPF every morning.
Over-exfoliation signs: stinging, tightness, flaking or a shiny, raw look. Stop the acids and retinal, keep it to a gentle cleanser, moisturizer and SPF until your skin settles.
Retinal safety
- Use it at night only, and wear sunscreen the next day (per celimax).
- New to retinoids? Start every other night for two weeks (per celimax).
- Don't use retinoids, including retinal, if you're pregnant, trying to get pregnant or breastfeeding, unless your doctor says it's OK.
Buying Dr.Althea? Avoid fakes
Dr.Althea has warned fans about counterfeit 345 Relief Creams sold online. The listing we link was sold by Dr.Althea and shipped by Amazon when we checked (Oct 23, 2026). Be wary of much cheaper offers, odd packaging or a strong scent: Ver.2 is fragrance-free (per Dr.Althea).
Patch-test first: try each new product on a small spot, like along your jaw, for a few days before using it all over. Add one new product at a time.

FAQ
Can I use azelaic acid and retinal together?
Many people do, but not on day one. Start one at a time. Once your skin is used to both, try azelaic acid in the morning and retinal at night, and ease off if you sting or peel.
Can I use the medicube Zero Pore Pads every day?
Start a few times a week. They contain lactic and salicylic acid, so daily use can over-exfoliate. Skip them on retinal nights, wear SPF by day, and stop if you sting, flake or turn red.
Is the celimax Retinal Shot safe during pregnancy?
Retinoids, including retinal, are generally avoided during pregnancy and breastfeeding. Ask your doctor before using it.
How do I avoid a fake Dr.Althea 345 Relief Cream?
Buy from the Dr.Althea brand store. The listing we link was sold by Dr.Althea and shipped by Amazon when we checked (Oct 23, 2026). Watch for much cheaper offers, odd packaging or a scent: Ver.2 is fragrance-free.
Does the d'alba spray serum replace moisturizer?
For most people, no. It's a light, glowy mist. Follow with moisturizer if your skin is dry, and patch-test first, since it contains fragrance.
What does azelaic acid do?
Azelaic acid helps with redness, bumps and the look of post-breakout marks. Anua's serum pairs 10% azelaic acid with hyaluronic acid and panthenol and suggests starting 1 to 2 times a week.
