Actives Combo Cheat Sheet (Short + Complete)

3 rules: 1) One main active per routine. 2) Keep acids away from retinol. 3) AM = Sunscreen first (Vitamin C is optional).

Fast plan: AM Hydration + SPF / PM Retinol (or Niacinamide) / Acids 1–2× per week.

⚠️ Sensitive skin notice:
If you have sensitive skin, rosacea, eczema, or you’re new to actives, start with one active only and use it 2–3 times per week. Vitamin C and retinol are optional, not mandatory.

If irritation occurs: pause actives for 3–7 days and focus on hydration + moisturizer.

Safe vs Avoid

✅ SAFE

Mini FAQ

Should I use Vitamin C in the morning?
Only if your skin tolerates it and your goal is brightening. The non-negotiable is sunscreen.

How often should I use AHA/BHA?
Start 1×/week → then 2×/week if your skin is okay.

What if I get irritation?
Stop actives, hydrate, and restart slowly (lower frequency).

Conclusion

The simplest “correct” plan: Keep mornings simple (hydration + SPF). At night, choose one main active (retinol or niacinamide), and use AHA/BHA on separate nights 1–2×/week.
