Dermafirm Soothing Repair Toning Serum

Glutathione isn't just for injections and pills anymore — Dermafirm packed it straight into a toning serum.

Dermafirm's R4 Soothing Repair line is built around nanoparticle-stabilized Glutathione, a lab-verified antioxidant that inhibits tyrosinase activity and helps convert stubborn dark eumelanin into lighter pheomelanin — the mechanism behind the serum's tone-evening claim. Niacinamide backs it up with extra brightening support, while natural Azulene calms flushed, stressed-out skin.

Bakuchiol and a peptide complex work alongside Eucalyptus and Perilla Leaf extracts to rebuild barrier function without the sting of harsher actives — this formula is designed for skin that's reactive from pollution, masks, or sun, not just skin that wants to look brighter.

As a toning serum, it slots in right after cleansing, prepping skin before the rest of your routine. Lightweight and fast-absorbing, it's for anyone dealing with uneven tone and easily irritated skin at the same time.
