@dr_ingky: Yes, you can use both in your skincare routine, but it's best to start by using them at different times to reduce irritation. Morning: Apply Vitamin C to help protect your skin against free radical damage, followed by sunscreen. Night: Use Adapalene (Differin Gel 0.1%) to treat acne and support skin cell turnover. Start twice a week and increase gradually as your skin tolerates it. If your skin starts stinging or becoming irritated, pause the active ingredients until it settles. Introduce products slowly, especially if you're a beginner. Save this for later!
