Key Ingredients in Niacinamide Skincare for Skin Barrier Support
Niacinamide is the anchor ingredient in this collection, and it works best alongside a few well-chosen partners. Here is what each one does, and where to find it across these formulas.
Niacinamide: What Vitamin B3 Does for Your Skin
Niacinamide, also called vitamin B3, is a water-soluble ingredient that helps skin look smoother, brighter, and more even. It supports the skin barrier by boosting ceramide production, so skin holds onto moisture better and the complexion feels balanced and comfortable rather than tight. Many people also notice a minimized look in the appearance of pores, smoother skin texture, and improvement in uneven texture with consistent use, which can also help skin tone look more refined and support the look of dark spots fading over time.
Niacinamide also helps regulate oil production and sebum production, which makes it especially useful for oily skin, acne prone skin, and blemish-prone skin. It can also reduce inflammation and visible redness, and it is generally well tolerated across many skin types, including sensitive skin and other prone skin. Because it is gentle and plays well with other ingredients, niacinamide is one of the most flexible additions you can make to a routine.
Most serums use a niacinamide concentration of 5-10%; 10% formulas are often chosen for excess oil, while stronger 10%+ options may cause redness for sensitive skin. You will find it in Reti-XO, where it sits alongside retinol, and in the Advanced TX Lightening Gel Elixir, a lightweight gel that helps support the look of an even, radiant complexion. As with any active, the results build gradually rather than overnight, so give it a few weeks of steady use before you judge it.

Retinol, Exosomes, and Pairing Niacinamide with Other Actives
Niacinamide and retinol pair well together, and so do niacinamide and vitamin C. The old idea that you cannot mix these actives does not hold up for most people. Niacinamide also layers well with hyaluronic acid and exfoliating acids when the rest of the routine stays gentle.
In fact, niacinamide can make stronger ingredients feel more comfortable, which is helpful if retinol has ever felt like too much for your skin. Reti-XO makes this simple, since it combines retinol and niacinamide in one evening step, so you get two well-studied ingredients without layering two separate products. Exosomes round out the formula as a modern delivery ingredient, chosen to help the actives feel at home on the skin.
If you prefer to build your own combination, a niacinamide serum layers cleanly under or over a vitamin C serum, and you can ease into options like glycolic acid slowly while it still sits comfortably beneath a moisturizer. The key is easing in slowly, keeping the rest of your routine gentle, and giving your skin time to adjust before adding anything new.
How to Build Your Niacinamide Routine
A good niacinamide routine is less about how many products you own and more about order and consistency. Niacinamide products generally go on after cleansing and before heavier creams, from thinnest to thickest texture, morning or night. For a deeper look at sequencing, see our layering guide.
A Dermatologist-Designed Routine for Morning and Evening
Here is a simple sequence you can follow, whether you are just starting out or refining an existing routine. Knowing how to use a niacinamide serum comes down to one idea: clean skin first, heavier products after.
- Cleanse. Start with a niacinamide cleanser or face wash like the Bubble Foaming Oxygenating Cleanser to remove the day without stripping the skin.
- Apply your serum to clean skin. Smooth a few drops over clean skin first. Use Reti-XO in the evening for retinol plus niacinamide, or reach for the Advanced TX Lightening Gel Elixir, a niacinamide gel, when you want a lighter step.
- Finish the morning with the B.B. Cream for a smooth, even-looking tint, then apply a broad-spectrum sunscreen, which dermatologists recommend every morning.
By day, the B.B. Cream works as a light, tinted finish. If you would rather use a dedicated niacinamide cream or niacinamide moisturizer, apply it after your serum and before sunscreen. In the evening, you can skip the tint and let your serum do the work under a simple moisturizer. Explore all our cleansers if you want to swap the first step for a different texture.
Layering Niacinamide with Retinol and Vitamin C
Layering sounds complicated, but the rules for niacinamide are forgiving. You can use niacinamide and retinol together, and Reti-XO already combines them in one step, so there is nothing extra to think about. You can also use niacinamide with vitamin C, and a common approach is vitamin C in the morning with niacinamide either time of day.
When people talk about medical-grade skincare, they usually mean higher-quality, well-formulated actives designed for comfort, not prescription-strength drugs, so there is no need to rush or overload your routine. Start with a serum a few times a week, then build up as your skin adjusts and tells you what it can handle.
