Power Pairing: Vitamin C + Tretinoin
Vitamin C + Tretinoin: Use With Caution
Vitamin C with Tretinoin can be effective, but skin tolerance determines success. This can be effective but is often better tolerated when split across AM and PM routines.
The Synergy
The pair can still be part of one regimen when scheduled carefully (for example alternating nights or splitting AM/PM). The key is controlled frequency and strong barrier support.
