PhilosophyLife Plankton — a thermal-spring microorganism — is the signature active, with a deep marine-based product architecture.Pharmaceutical-grade EGF, made gentle.

Biotherm

The French pharmacy brand most people forget exists. Life Plankton Essence is a legitimate hero serum that's been consistently reformulated since 1952. Aquasource gel moisturizer is a classic. L'Oréal ownership has watered down the 'prestige pharmacy' positioning a bit. Still a reasonable pick for hydration-forward routines.

Pros

✓ Life Plankton has real research behind it
✓ Strong hydration-focused lineup
✓ Widely available globally
✓ Reasonable premium-pharmacy pricing

Cons

✗ Brand energy has dipped in 2020s
✗ Formulations less distinctive than they used to be
✗ Not really a pharmacy brand — sold mostly at Sephora/department stores

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.
