Our Pick
Mediheal
Higher editor rating (9 vs 8.7)
iS Clinical
iS Clinical is the cosmeceutical brand dermatologists' offices actually stock — the line that sits next to ZO Skin Health and SkinCeuticals on the recommendation card. Founded in 2003 by Bryan Johns and Alec Call out of a research background in pharmaceutical and oncology applications, the brand built its reputation on the Active Serum (a multi-acid + arbutin + bilberry serum that handles acne, pigmentation, and aging in one bottle) and Pro-Heal Serum Advance+ (the post-procedure recovery formulation that aestheticians dispense after laser, micro-needling, and chemical peels). Distribution stays selective — dermatologist offices, medical spas, and authorized retailers — which keeps the brand premium but limits casual discovery.
Pros
- ✓ dermatologist-and-aesthetician channel pedigree
- ✓ Active Serum is a genuinely versatile multi-active hero
- ✓ Pro-Heal Serum Advance+ is the gold-standard post-procedure formulation
- ✓ iron-oxide mineral SPF (Eclipse) is one of the cleanest in the market
Cons
- ✗ pharmaceutical pricing tier ($95-170 per product)
- ✗ selective distribution makes purchase harder than DTC brands
- ✗ marketing aesthetic feels dated next to modern cosmeceutical brands like Augustinus Bader
- ✗ INCI complexity makes it harder for casual users to understand
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.
