How to Layer Skincare Serums: Vitamin C, Niacinamide, Retinol & Peptides
Serum layering can become complicated very quickly. The goal is not to fit every active ingredient into one routine. A better approach is to choose products for your main concern, layer compatible textures sensibly and keep enough space in the routine to notice how your skin responds.
Start with your main goal
Before deciding on order, decide what you actually want from the routine. Brightening and even-looking tone, fine-line care, hydration and skin comfort may lead to different product choices. You can compare formulas in the Ammuri Face Serums collection.
A practical layering rule
When product directions do not specify otherwise, lighter water-based textures usually go before richer creams or oils. But ingredient compatibility and skin comfort matter more than blindly following “thinnest to thickest”.
Vitamin C
Vitamin C is often used in the morning as part of a brightening routine, followed by moisturiser and SPF. It can also appear in evening formulas. If your routine already contains several active products, keeping vitamin C to one part of the day can simplify things.
Niacinamide
Niacinamide is flexible and can fit into morning or evening routines. It is commonly paired with hydrating products and can be used alongside many other cosmetic ingredients.
Peptides
Peptide serums are often easy to position after cleansing and before moisturiser. They can be useful on mornings when you want a simpler anti-ageing routine without retinol.
Retinol
Retinol is usually an evening step. Rather than stacking it with every other strong active, many people get a simpler routine by keeping selected retinol nights and using other serums on alternate nights or in the morning.
Example morning routine
- Cleanser
- Vitamin C or niacinamide serum
- Peptide serum if your routine benefits from another layer
- Moisturiser
- SPF
Example evening routine
- Cleanser
- Niacinamide or peptide serum
- Retinol on appropriate nights
- Moisturiser
When should you stop layering?
If products pill, the routine feels heavy, or your skin becomes persistently uncomfortable, reduce the number of layers. Consistency with a few suitable products is more useful than an overloaded routine.
Frequently asked questions
Do I need more than one serum?
No. One well-chosen serum can be enough. Additional products should have a clear role.
Can I use vitamin C and retinol in the same routine?
Some users do, but separating vitamin C into the morning and retinol into the evening is often a simpler starting point.
What comes last in the morning?
Broad-spectrum SPF should be the final skincare step before makeup.
