Not sure if you’re applying your skincare products in the right order? Skincare layering can make or break your routine. When done right, it ensures each ingredient absorbs properly and works effectively—especially if you’re using multiple serums or actives like retinol, niacinamide, or acids. In this guide, we break down the science-backed skincare routine order so your products can work smarter, not harder.

Key Points

• Skincare layering affects absorption and product efficacy.
  

• General rule: apply from thinnest to thickest texture.
  

• AM and PM routines differ based on ingredient sensitivity.
  

• Certain actives (like acids and retinol) need careful placement.
  

• Proper waiting times between layers improve results.
  
  

Why Skincare Layering Matters

Layering isn’t just about aesthetics—it’s chemistry. Ingredients need to be absorbed in the right environment to work their best. For example, humectants like hyaluronic acid draw moisture into your skin, but if sealed incorrectly, they can backfire. Similarly, applying retinol after the wrong product can cause irritation.

The Golden Rule of Skincare Order: Thinnest to Thickest

Start with water-like consistencies (toners, essences), move on to serums, and finish with thicker creams or oils. This maximises absorption and keeps active ingredients close to the skin.

Morning vs. Night Skincare Routine Order

Morning Skin Care Routine Order

1. Cleanser – Gentle, non-stripping to refresh the skin.
   

2. Toner (optional) – Hydrating or balancing formula.
   

3. Antioxidant Serum – Like vitamin C to protect against free radicals.
   

4. Moisturizer – Locks in hydration.
   

5. Sunscreen – A non-negotiable final layer to protect your skin.
   
   

Night Skin Care Routine Order

1. Double Cleanse – Use an oil-based cleanser, then follow with a gentle foaming cleanser.
   

2. Hydrating Toner/Essence – Preps the skin and adds moisture.
   

3. Targeted Serums – Think retinol, AHAs, BHAs, peptides.
   

4. Moisturizer or Oil – Supports the skin barrier overnight.
   

5. Spot Treatment (if needed) – Only on affected areas after moisturizer.
   
   

How to Layer Serums Like a Pro

Yes, you can layer multiple serums—but stick to 2–3 at most to avoid overwhelming your skin. Start with the thinnest serum first and give each layer time to absorb (about 30 seconds to 1 minute).

The Right Order to Apply Popular Ingredients

Niacinamide and Hyaluronic Acid

Apply hyaluronic acid first (it's thinner and helps hydrate the skin), then follow with niacinamide. These two are very compatible.

Retinol and Hyaluronic Acid

Use hyaluronic acid before and after retinol. It cushions the skin, reducing dryness and irritation.

Glycolic Acid and Niacinamide

Avoid layering these in the same session. Alternate nights, or apply glycolic acid first, wait 20–30 minutes, then apply niacinamide to soothe.

Salicylic Acid and Niacinamide

Can be layered. Use salicylic acid first (to unclog pores), then niacinamide to calm and strengthen the barrier.

How Long to Wait Between Layers

For most routines, wait 30 seconds to 1 minute between steps. When using actives like acids or retinol, wait 10–20 minutes to minimize pH conflicts and reduce irritation.
