Niacinamide, Vitamin C and retinol are three of the most searched-for skincare ingredients — and one of the most common questions we hear is whether they can all be used together, and in what order. Here's a considered, straightforward answer, and how we've built La Lei's own routine around it.
Why Start With Niacinamide
Niacinamide (Vitamin B3) is widely regarded as one of the more gentle, well-tolerated actives in skincare, which is exactly why it makes a sensible foundation step. It's formulated to help support the skin's moisture barrier — the outer layer that keeps hydration in and everyday irritants out — which matters because a well-supported barrier is generally what allows the rest of a routine, including stronger actives like Vitamin C and retinol, to be tolerated more comfortably.
La Lei's Barrier B is built around 10% Niacinamide and Hyaluronic Acid, alongside the patented, botanically sourced L22 lipid complex — a considered starting point for exactly this reason.
Can You Use Niacinamide With Vitamin C?
Yes. Modern, stable formulations of niacinamide and Vitamin C are broadly considered compatible with one another, and many routines use both — niacinamide for barrier support, Vitamin C for brightening and antioxidant benefits. Older advice that the two shouldn't be combined largely reflects outdated ingredient stability issues that don't generally apply to the way these actives are formulated today.
Can You Use Niacinamide With Retinol?
Yes, generally — niacinamide is often recommended alongside retinol specifically because it can help make a retinoid routine more comfortable, given its role in supporting the skin barrier. Retinol itself should still be introduced gradually, regardless of what else is in your routine — starting a few evenings a week and building up as your skin adjusts, rather than using it nightly from the first application.
A Simple Layering Order
There's no single correct order that works for everyone, but a sensible general approach looks like this:
Morning: Cleanse, niacinamide serum, Vitamin C serum or oil, moisturiser, SPF.
Evening: Cleanse, niacinamide serum, retinol treatment (on the evenings you're using it), moisturiser.
The general rule is lightest, most water-based formulas first, richer or oil-based formulas last — and if you're introducing more than one active at a time, it's worth slowing down rather than layering everything on at once.
Building Up Gradually
If you're new to actives, or introducing several at once, start with one new product at a time and patch-test before applying it to your full face. This is particularly worth doing with retinol, which is typically introduced a few nights a week before building up frequency, rather than niacinamide or Vitamin C, which are generally better tolerated from the outset.

FAQs
Can I use niacinamide, Vitamin C and retinol all in the same routine?
Yes — many routines include all three, typically with niacinamide as a year-round foundation, Vitamin C in the morning, and retinol in the evening (introduced gradually). They're generally considered compatible with one another in modern formulations.
Should I apply niacinamide before or after Vitamin C?
A common approach is niacinamide first, followed by Vitamin C — but formulation and personal preference both play a role, and there's no single rule that applies to every product.
Will niacinamide reduce irritation from retinol?
Niacinamide's role in supporting the skin barrier is part of why it's often paired with retinol, but it isn't a substitute for introducing retinol gradually. Build up frequency slowly regardless of what else is in your routine.
How long should I wait between applying different actives?
Most water-based serums can be layered within a minute or two of each other, allowing each to absorb before the next. If you're combining several new actives for the first time, introducing them one at a time over a few weeks is a more considered approach than layering everything at once.
