- •Neither list discloses vitamin C concentration. Efficacy depends heavily on percentage and pH, neither of which is shown here.
- •Ascorbic Acid stability varies by formulation pH and packaging. Opaque or airless packaging matters but cannot be assessed from an ingredient list.
- •Drunk Elephant C-Firma Fresh Day Serum's curcumin derivatives (tetrahydrodiferuloylmethane analogues) have emerging but limited clinical data compared to L-Ascorbic Acid.
- •Dimethyl Isosorbide in Drunk Elephant C-Firma Fresh Day Serum enhances penetration of all ingredients, not just actives. This could amplify irritants too.
- •Timeless 20% Vitamin C + E Ferulic Acid Serum's identified resemblance to SkinCeuticals C E Ferulic is inferred from formula pattern, not confirmed branding.
- •Ferment extracts in Drunk Elephant C-Firma Fresh Day Serum provide conditioning benefits but standardization varies by manufacturer.
- •Hydrolyzed Wheat Protein appears relatively late in Drunk Elephant C-Firma Fresh Day Serum's list, suggesting a low concentration.
