Our Pick
Mediheal
Higher editor rating (9 vs 8.6)
Su:m37°
Su:m37° bet its entire identity on one idea: ferment everything, for exactly 365 days, and don't add synthetic preservatives. The Secret Essence is what happens when that philosophy actually works — a naturally-fermented essence with legitimate cult status. Not cheap, not preachy, and the formulas have held up for 15+ years.
Pros
- ✓ Serious fermentation science
- ✓ Minimal synthetic preservatives
- ✓ Cult Secret Essence
Cons
- ✗ Luxury pricing
- ✗ Heavy natural fragrance
- ✗ Spa-lady packaging
Mediheal
Mediheal is the top-selling skincare brand at Olive Young for two years running — beating more than 3,000 brands. Their sheet masks created the modern sheet mask category, and their Madecassoside Blemish Pad saw 820% year-over-year growth. If you only add one new sheet mask brand to your routine, make it this one.
Pros
- ✓ #1 selling brand at Olive Young
- ✓ Clinical-grade sheet mask formulations
- ✓ The Madecassoside line is category-defining
- ✓ Affordable daily-use pricing
Cons
- ✗ Sheet masks are single-use and generate waste
- ✗ Some older lines contain fragrance
- ✗ Huge catalog can be overwhelming
