Our Pick
MartiDerm
Higher editor rating (8.8 vs 8.7)
MartiDerm
MartiDerm is the brand built around a single iconic format: the snap-top glass ampoule. Founded in 1952 as a pharmacy in Cervelló, just outside Barcelona, the modern brand was born when pharmacist José Martí Tor formalised the pharmacy's house formulations into commercial dermocosmetics in 1989. The signature is the proteoglycan ampoule — nitrogen-flushed glass vials of 5% pure L-ascorbic acid + proteoglycans + hyaluronic acid, sealed to keep vitamin C from oxidising until the moment of use. In Spain the ampoule before a wedding is a literal cultural ritual — and MartiDerm's Photo-Age HA+ is the ampoule. The newer DSP-Bright and Proteos Hydra Plus extend the format to pigmentation and pure plumping. The format itself is the differentiator: every dose is fresh, every ml is delivered through a system that the air can't oxidise.
Pros
- ✓ nitrogen-flushed glass ampoule format — solves vitamin C oxidation that ruins most C serums
- ✓ 5% pure L-ascorbic acid + proteoglycans — clinical-tier dose, fresh per use
- ✓ the ampoule-before-event ritual is a Spanish cultural anchor
- ✓ proteoglycan technology adds plumping that pure HA doesn't
Cons
- ✗ glass ampoules are not travel-friendly and produce more waste than a pump
- ✗ snapping the ampoule requires care — sharp glass risk if mishandled
- ✗ premium per-ml cost vs. equivalent serum bottles
- ✗ the ampoule format is unfamiliar to non-EU shoppers
EasyDew
EasyDew is built on real medical chemistry — the brand was founded by Daewoong Pharmaceutical and uses pharmaceutical-grade EGF (Epidermal Growth Factor), an ingredient most OTC skincare can't legally formulate with at this concentration. Olive Young named them their #1 'slow aging' brand in 2025, and Marie Claire flagged them as one of the K-beauty brands to watch.
