Separate routines: excessive low-pH burden
Pharmacological Mechanism
Pure L-ascorbic acid requires an acidic pH (approx. 3.0) for cutaneous penetration. Stacking it with chemical exfoliants (glycolic or salicylic acid) compounds acid stress on the acid mantle.
Miko Routine Guidance
Dedicate Vitamin C to AM photoprotection routines and reserve AHA/BHA exfoliants for PM.
