Niacinamide is one of the most useful all-rounders in skincare. Also known as nicotinamide, this form of vitamin B3 has been widely studied for its ability to support the skin barrier while improving the appearance of uneven tone, texture, redness and visible signs of ageing. It is also easy to combine with other skincare ingredients, which makes it particularly valuable in a simple routine where every product needs to earn its place.
At Krī, niacinamide is at the heart of Illume Niacinamide Serum. Illume combines 5% niacinamide with glycerin and sodium hyaluronate, so it is not only a treatment serum for tone and texture but an effective hydrating step too.
What does niacinamide do for skin?
One of niacinamide's most important benefits is its support for the skin barrier. Research suggests that topical niacinamide can improve the skin's ability to retain moisture and influence its lipid and ceramide content. In practical terms, that matters because a well-supported barrier helps skin feel more comfortable, supple and resilient. In Illume Niacinamide Serum, that barrier-focused benefit sits alongside glycerin and sodium hyaluronate, which provide immediate lightweight hydration.
Niacinamide is equally interesting for the way skin looks. Clinical research has reported improvements in fine lines and wrinkles, hyperpigmented spots, texture, redness and sallowness with regular topical use. This makes it far more than an ingredient for oily or blemish-prone skin; it is particularly relevant to mature skin, where several of those concerns often appear together.
Niacinamide for uneven tone and texture
Uneven pigmentation and rough texture can make the complexion look duller and less refined. Niacinamide has been studied for both, including research into its effect on melanosome transfer within the skin and clinical studies reporting improvements in hyperpigmented spots. Alongside its effects on texture, the result we are interested in is straightforward: skin that looks smoother, brighter and more even.
Is niacinamide good for mature skin?
Very much so. As skin ages, hydration, barrier function, pigmentation and texture can all become more noticeable concerns. Niacinamide addresses several of these areas at once, which is why we consider it such a useful everyday active. A hydrating niacinamide formula such as Illume Niacinamide Serum is especially easy to incorporate because it gives mature skin additional water-based hydration without adding heaviness.
What percentage of niacinamide is best?
Higher percentages are not automatically better. Niacinamide has demonstrated benefits at relatively modest concentrations, including clinical research using 5% formulations. We use 5% in Illume Niacinamide Serum because it gives us a meaningful level of niacinamide within a balanced hydrating formula rather than turning skincare into a competition over the largest number on the label.
Can you use niacinamide with Vitamin C?
Yes. The old idea that niacinamide and Vitamin C should not be used together does not reflect the way modern skincare is formulated. In fact, they make a very useful pairing: niacinamide supports hydration, barrier function, tone and texture, while Vitamin C adds focused antioxidant and brightening care.
A simple morning routine could therefore begin with Unveil Oil-to-Milk Cleansing Oil, followed by Illume Niacinamide Serum and then Vitamin C + Bakuchiol Serum. Follow with moisturiser if needed and finish with sunscreen.
Can you use niacinamide every day?
Niacinamide is well suited to regular use and can be used morning, evening or both. There is no need to layer several niacinamide products simply because the ingredient is beneficial; one well-formulated product used consistently is enough. Illume Niacinamide Serum is designed to cover both treatment and hydration in a single lightweight step, which is precisely why it is one of our hero products.
Why we use niacinamide at Krī
Niacinamide earns its place because it does several useful things exceptionally well. It supports the barrier, helps skin retain moisture, and has good evidence behind improvements in tone, texture and visible signs of ageing. In Illume Niacinamide Serum we pair it with glycerin and sodium hyaluronate so those treatment benefits come with meaningful hydration too. The result is a serum that fits easily into almost any routine and leaves skin feeling hydrated while looking smoother, brighter and more even.
