Niacinamide in Skincare
Clinical Evidence, Mechanisms of Action, and Why It Is One of the Most Versatile Actives in Skincare Formulation
Niacinamide — also known as nicotinamide or vitamin B3 — is one of the most thoroughly researched and widely used actives in skincare. It addresses multiple formulation objectives including barrier support, pigmentation, photoaging, sebum regulation and skin tolerance.
Its broad formulation compatibility and established clinical evidence make it particularly useful for multi-benefit skincare systems. This page explores the science behind niacinamide and the rationale for evaluating it in the EVIK™ LyoPearl freeze-dried bead format.

Clinical studies and reviews have investigated topical niacinamide across multiple skin parameters. Five major mechanisms are particularly relevant to skincare formulation.
Skin Barrier Enhancement & Ceramide Synthesis
Niacinamide is involved in cellular NADH and NADPH metabolism, which supports processes involved in epidermal lipid and protein synthesis. Topical niacinamide has been associated with increased production of ceramides and barrier-related proteins including keratin, involucrin and filaggrin.
Clinical studies have reported reductions in transepidermal water loss (TEWL) and improvements in barrier function, with additional evidence suggesting improved tolerance to potentially irritating skincare ingredients.
Skin Brightening & Melanosome Transfer
Niacinamide can inhibit the transfer of melanosomes from melanocytes to keratinocytes. This mechanism differs from direct inhibition of tyrosinase, the enzyme involved in melanin synthesis.
Clinical research has reported improvements in hyperpigmentation, sallowness and uneven skin tone with topical niacinamide.
Anti-Aging & Photoaging Improvement
Niacinamide contributes to cellular NAD+ metabolism, which is relevant to cellular energy, oxidative stress and age-associated skin changes.
Studies using topical niacinamide have reported improvements in fine lines, wrinkles, skin texture and the appearance of photoaged skin. Reviews have also described effects related to barrier function, pigmentation and oxidative stress.
Sebum Regulation & Pore Appearance
Topical niacinamide has been studied for its ability to reduce sebum excretion. This makes it relevant to oily, acne-prone and combination skin formulations where oil control is combined with other objectives such as brightening or anti-aging.
Anti-Inflammatory Activity & Tolerance Enhancement
Niacinamide has demonstrated anti-inflammatory activity relevant to several dermatological and cosmetic applications. Its profile is associated with reduced redness and irritation and has also made it useful as a supporting ingredient alongside potentially irritating actives.
This includes formulation systems containing retinoids, exfoliating acids and other high-efficacy ingredients where barrier support and tolerability are important development objectives.
Why Niacinamide Works Across So Many Formulations
One of niacinamide's most practically valuable characteristics is its broad formulation compatibility. It can be incorporated into many multi-active skincare systems and evaluated alongside commonly used cosmetic ingredients.
Hyaluronic Acid
A complementary combination pairing hydration support with niacinamide's barrier, brightening and multi-benefit activity.
Peptides
Niacinamide can be incorporated into peptide-containing skincare systems for multi-functional formulation evaluation.
Retinoids
Niacinamide is commonly paired with retinoid systems where barrier support and improved tolerability are formulation goals.
Ascorbic Acid
Historical concerns around niacinamide and acidic vitamin C systems have been investigated extensively. Actual compatibility depends on concentration, pH, temperature and formulation design.
AHAs & BHAs
Niacinamide can be evaluated alongside exfoliating systems where barrier support is an important formulation objective.
Multi-Active Systems
A pure niacinamide bead can be evaluated in an existing carrier to investigate compatibility and additive contribution.
Why Freeze-Dried Niacinamide Beads?
EVIK™ LyoPearl provides niacinamide in a dry, precisely dosed bead format designed for research, formulation evaluation and single-dose skincare development.
Pure Dry-State Active
Niacinamide is supplied in a dry bead rather than pre-dissolved into a liquid carrier.
Precise Single Dose
Each bead contains a defined amount of niacinamide for controlled formulation and evaluation.
Preservative-Free Dry Format
The dry bead format avoids the need for a liquid preservative system within the bead itself.
Defined Reconstitution
The bead can be dissolved into a defined volume of water or suitable carrier to target a specific concentration.
Multi-Active Evaluation
Useful for investigating niacinamide alongside existing skincare actives and carrier systems.
Custom Bead Specifications
Custom niacinamide content and formulation specifications can be discussed with the Evik Diagnostics team.

Preservative-Free Multi-Active Systems
Explore single-dose niacinamide delivery concepts for waterless, clean-beauty and free-from formulation development.
A Note on Concentration and Dissolution
The final application concentration depends on the niacinamide content of the bead and the volume of carrier used for reconstitution.
Clinical studies demonstrating niacinamide efficacy have commonly evaluated topical concentrations in the 2–5% range, while consumer products may use a broader range depending on the product concept.
EVIK™ LyoPearl Niacinamide contains 12.8 mg of niacinamide per bead at 100% dry weight. The final concentration after dissolution depends on the volume of water or carrier used.
The large bead size and defined active content make the format suitable for concentrated single-dose treatment concepts or for dissolution into a controlled volume of carrier serum.
Contact the Evik Diagnostics team to discuss dissolution protocols, target use concentration or custom niacinamide content per bead.
EVIK™ LyoPearl Niacinamide
EVIK™ LyoPearl Niacinamide is available for research and evaluation. Each bead contains 12.8 mg of niacinamide at 100% dry weight in a 30 μL bead. Supplied as 10 LyoPearls per vial.
