Compare Products: C-Firma Fresh Day Serum vs Vitamin C Serum for Face
Ingredient Analysis
Drunk Elephant C-Firma Fresh Day Serum carries a stronger, more bioavailable vitamin C form with proven penetration enhancers and a richer supporting cast of actives. TruSkin Vitamin C Serum for Face uses a gentler, more stable vitamin C derivative with botanical extracts, suiting sensitive or reactive skin better.
Drunk Elephant C-Firma Fresh Day Serum uses pure Ascorbic Acid, the gold-standard form. TruSkin Vitamin C Serum for Face uses Sodium Ascorbyl Phosphate, which is gentler but less potent.
TruSkin Vitamin C Serum for Face's vitamin C derivative is far less likely to sting. Drunk Elephant C-Firma Fresh Day Serum's low-pH Ascorbic Acid may irritate sensitive skin.

Drunk Elephant C-Firma Fresh Day Serum includes crosslinked Sodium Hyaluronate plus standard Sodium Hyaluronate, offering layered moisture. TruSkin Vitamin C Serum for Face relies on a plant-derived film former.
