What Niacinamide Actually Does for Your Skin

Niacinamide has become one of the most commonly listed ingredients in skincare. It appears in toners, serums, moisturizers, and eye creams — often at different concentrations, without much explanation of what it actually does or why it's included. Here is a clear, honest answer.

What Niacinamide Is

Niacinamide is a form of Vitamin B3, a water-soluble vitamin with a well-documented role in cellular metabolism. In topical skincare, it has been studied for several distinct functions — which is part of why it appears so frequently. It is a genuinely versatile ingredient with a strong safety profile across most skin types.

What the Evidence Says It Does

Supports the skin barrier. Niacinamide plays a role in the synthesis of ceramides — lipids that are integral to the skin's protective barrier. A stronger barrier means better moisture retention, reduced sensitivity, and improved resilience to environmental stressors.

Reduces the visible appearance of pores and uneven texture. At concentrations typically between 2% and 5%, niacinamide has been shown to reduce the appearance of enlarged pores and improve skin texture with consistent use over several weeks.

Addresses uneven skin tone. Niacinamide interrupts the transfer of melanin — the pigment responsible for dark spots — to the surface of the skin. It does not lighten skin overall. It helps even out areas of hyperpigmentation, including post-acne marks and sun-related discoloration.

Regulates sebum production. Studies have found that niacinamide can reduce sebum excretion, making it useful not just for dry or combination skin, but also for those prone to oiliness or congestion.

Soothes and calms. Niacinamide has documented anti-inflammatory properties, which makes it one of the few actives that is well-tolerated across a wide range of skin types — including sensitive and reactive skin.

What to Look for

Concentration. Most studies on niacinamide have used concentrations between 2% and 5%. Below 2%, visible effects may be limited. Above 5%, some individuals with very sensitive skin may experience temporary flushing — though this is uncommon at standard topical usage levels.

Stability. Niacinamide is water-soluble and relatively stable in formulas. It does not degrade quickly with light or air exposure the way some actives do, which makes it appropriate for both day and evening use.

Pairing with Vitamin C. There is a longstanding myth that niacinamide cannot be used alongside Vitamin C. This has been largely refuted by modern formulation science. The two can coexist in a well-formulated product without issue — and stabilized forms of Vitamin C, like Ascorbyl Glucoside, are particularly compatible.

How We Approach This at Clique Beauty

In the Radiance Face Cream

We use 2% Niacinamide — a concentration appropriate for daily use across most skin types. It works alongside stabilized Vitamin C (Ascorbyl Glucoside), Sodium Hyaluronate, Squalane, and Organic Shea Butter to support both hydration and barrier integrity. The formula also includes Jojoba Oil and a botanical complex (Alchemilla Vulgaris, Malva Sylvestris, Melissa Officinalis, Mentha Piperita, Veronica Officinalis, Primula Veris) to support overall skin comfort.

In the Illuminate Advanced Eye Cream

The eye area presents a specific set of challenges: skin is thinner, more delicate, and more prone to fluid accumulation than the rest of the face. Our Illuminate Advanced Eye Cream includes 5% Niacinamide — a higher concentration appropriate for tone-evening and barrier support in the periorbital zone. It is combined with 1% Caffeine, Sodium Hyaluronate, Squalane, Avocado Oil, Tocopherol, and Chamomile Flower Water. The formula is both dermatologically and ophthalmologically tested, and has demonstrated +37% improvement in eye area hydration in independent testing.

In both formulas, niacinamide is included for functional reasons — not as a label claim or a trend ingredient. Every active in a Clique Beauty formula is there because it serves a purpose.

A Note on Expectations

Niacinamide is not an overnight fix. Its effects — particularly on pore appearance and skin tone — build gradually with consistent use. Studies typically measure outcomes at four, eight, and twelve weeks. That is not a limitation of the ingredient; it is how skin physiology works. The timeline is longer than marketing often suggests, and worth knowing before you start.

✦  Both the Radiance Face Cream and the Illuminate Advanced Eye Cream include niacinamide as part of their active ingredient profiles. If barrier support and a more even complexion are priorities in your routine, they may be worth exploring together.
