EUK 134 0.1% — Reddit Reviews
by The Ordinary
Updated September 26, 2026
Antioxidant serum for night use; pre/post sun exposure and redness support.
What the community says
A barebones antioxidant serum in propanediol, usually used at night or before sun exposure. Best for people who want extra antioxidant support and a non-oily hydration boost. Don’t expect a dramatic visible payoff, and some avoid it with acids or copper peptides.
