Brand Comparison
Isoi vs MEDI-PEEL
A head-to-head comparison of two popular K-beauty brands. Which one is right for your skin?
Our Pick
MEDI-PEEL
Larger product range
Isoi
Isoi has been quietly excellent for nearly two decades, but 2025 is its breakout year. The Blemish Care Up Serum picked up multiple Hwahae nods, and dermatology-leaning K-beauty fans have been quietly recommending it for fading post-acne marks for years. Premium-leaning but worth it.
Pros
- โ Long track record on PIH and dark spots
- โ Damask rose hero ingredient
- โ Hwahae 2025 award winner
Cons
- โ Premium pricing
- โ Heavier rose scent
MEDI-PEEL
MEDI-PEEL is the K-beauty brand Korean dermatologists actually stock in their clinic shops. Built around three flagship technologies โ Peptide 9 (a peptide-stack treatment line), Red Lacto Collagen (a lactobacillus-ferment line), and PDRN/salmon-DNA (their Bio-Tox category) โ the brand consistently overdelivers on actives at the $25โ45 price point. The Peptide 9 Volume Bio Tox Ampoule is the entry point most people meet first; the Red Lacto Collagen Cleansing Balm has quietly become one of the most-recommended balm cleansers in K-beauty forums. Not a magazine brand and not trying to be one โ the visual identity is clinical, the claims lean medical, and the formulations are dense. Buy MEDI-PEEL when you want results without the SKII or Sulwhasoo price tag.
Pros
- โ high-concentration peptide and PDRN formulations at affordable pricing
- โ clinical-leaning packaging and claims that match actual ingredient density
- โ broad global distribution (YesStyle, Stylevana, Olive Young, Amazon)
- โ Korean dermatology clinic shelf presence
