How to Layer Your Skincare Products the Right Way

The general rule for layering skincare is: lightest texture first, heaviest last. But there are nuances — some products are pH-dependent, some should never be mixed, and the gap between applications can matter.

The Core Principle: Thinnest to Thickest

Water-based products with small molecules (like serums) need to penetrate before thicker film-forming products (like moisturisers and sunscreen) seal them in. If you apply a heavy cream first, serums can't penetrate properly.

Morning Routine

• Cleanser — remove overnight sebum and residue
• Toner — balance pH and prep skin
• Vitamin C serum — antioxidant protection pairs with sunscreen
• Moisturiser — lock in hydration
• SPF 30+ — always the final step

Evening Routine

• Double cleanse — oil cleanser first, then water-based
• Exfoliant or treatment (AHA/BHA) — 2–3 nights per week
• Niacinamide serum — for pore refinement and brightening
• Retinol or peptide serum — for anti-ageing (alternate nights)
• Rich moisturiser or face oil — seal everything overnight

Applying products in the wrong order isn't just ineffective — it can actively reduce the potency of your actives and irritate your skin barrier.

Combinations to Avoid

Retinol + AHAs: both are potent exfoliants that can over-irritate when used simultaneously. Vitamin C + Retinol: different pH requirements reduce efficacy — use Vitamin C in the morning and retinol at night.

Wait Times Matter

Vitamin C and AHA/BHA products have lower pH formulations. Give them 20–30 minutes before your next step so they can work at the correct pH. For most other products, 60 seconds is sufficient.
