Bis-Ethylhexyl Hydroxydimethoxy Benzylmalonate

Also-called-like-this: RonaCare AP, HDBM
What-it-does: antioxidant


A clear, colorless liquid that gives advanced protection for the skin lipids and truly photostabilizes UV filters, at least according to its manufacturer. It's as effective of an antioxidant as pure Vitamin E, aka tocopherol and as stable as its esterified version tocopheryl acetate.

It's claimed to efficiently and continuously work over 24 hours by a continuous three-phase mechanism: it dims oxidative stress, builds up protection from ROS (evil free radicals) and prevents the formation of further reactive species.

If that would not be enough, it also seems to be a promising ingredient for acne prevention. In an in-vivo test on 22 volunteers, a 2% Bis-Ethylhexyl Hydroxydimethoxy Benzylmalonate formula decreased skin oiliness by 20% after 8 weeks of treatment, and skin inflammation and redness also improved by 25%.

Show me some proof
