01 · THE STARTING POINT
The niacinamide paradox
Powerful biology — yet inseparable from the water phase.
Niacinamide — the amide form of vitamin B3 — is one of the best-documented multifunctional cosmetic actives, driving epidermal energy metabolism as a precursor of the NAD+/NADP+ coenzymes. Its physicochemical nature, however, makes it extremely hydrophilic:
· Readily soluble in water, almost insoluble in non-polar oils (logP≈−0.4)
· No molecular affinity for lipid phases — whenever water is present, it partitions into the water phase
· Once deprived of an aqueous environment, it re-crystallizes
· Traditional formulas must therefore carry a water phase or solubilizers
Physicochemical data: PubChem CID 936 (Niacinamide).
Formats that conventional niacinamide struggles to enter
Facial oil serums & oil essences · Anhydrous concentrates & balms · Lipid-rich barrier-repair formulas · Oil-continuous emulsions · Functional cleansing oils · Premium scalp & hair oils
The limitation is not biological — it is a delivery-engineering problem.
02 · MARKET CONTEXT
The rise of active oil-based beauty
Oil-based skincare is moving beyond simple emollience and occlusion. Barrier science, anhydrous formats and the “skinification” of scalp care are redefining what lipid-based products are expected to deliver.
01Barrier-first skincare — lipid replenishment becomes a core claim
02The facial-oil renaissance — from finishing step to efficacy step
03Scalp & hair “skinification” — facial-grade actives move to the scalp
04Anhydrous formulation — concentrated, minimalist architectures
05Premium sensorial textures — lipid richness as a signifier of efficacy
THE EMERGING PRODUCT ARCHITECTURE
Lipid base + functional actives + advanced delivery technology
A new generation of oil-based skin, scalp and hair care.
The long-missing link — a water-soluble active that can work in the oil phase.
PURIPHARM · PRODUCT LAUNCH
A water-soluble active — new possibilities in the oil phase.
NanoActive OleoNia™
An oil-compatible niacinamide delivery system: through a lipid-associated form, it re-engineers how a classic water-soluble active exists — allowing facial oil serums, anhydrous concentrates, balms and oil-rich scalp care to carry niacinamide biology for the first time.

Nano-lipid vesicle structure — the delivery core of NanoActive OleoNia™.
INCI name Niacinamide
Technology platform PURISOME® FlexVes™ liposome technology
Product line NanoActive™
03 · THE TECHNOLOGY
From water-soluble to oil-compatible
Constraints of the conventional route
· Hydrophilic molecules dissolve only where a water phase exists
· In anhydrous oils they persist as undissolved crystalline solid
· Phase separation and uneven distribution follow
· No inherent affinity for the lipid environment of skin or formula
The OLEONIA™ approach
· Skin-affine phospholipids build an amphiphilic vesicle structure
· The hydrophilic active is compartmentalized inside the vesicle core
· A lipid-compatible outer interface allows dispersion in the oil phase
· Uniform incorporation in oil-continuous systems

Schematic: the hydrophilic active resides inside a lipid-assembled carrier, turning a water-dependent molecule into an oil-dispersible system.
03 · THE TECHNOLOGY
Vesicle architecture — PURISOME® FlexVes™ technology

1. Amphiphilic bilayer membrane.Skin-affine phospholipids self-assemble into a closed bilayer, following the same organizing principle as epidermal barrier lipids.
2. Active compartmentalization.Hydrophilic niacinamide is located in the vesicle core — physically separated from the surrounding oil-continuous phase.
3. Lipid-compatible outer interface.The outer membrane presents a non-polar surface, letting the carrier disperse uniformly in oils and lipid-rich bases.
4. Flexible-vesicle engineering.The FlexVes™ membrane design optimizes vesicle deformability and stratum-corneum affinity — properties the literature links to enhanced skin deposition.
FOUR PLATFORM FUNCTIONS
Active protection → enhanced skin deposition → sustained availability → formula & sensory compatibility

04 · ACTIVE BIOLOGY
Skin barrier — rebuilding the lipid “mortar”
As an NAD+/NADP+ precursor, niacinamide powers keratinocyte energy metabolism and epidermal differentiation — the engine of barrier-lipid synthesis.
Ceramide biosynthesis.Niacinamide promotes de novo synthesis of ceramides and other stratum-corneum lipids in human keratinocytes, improving epidermal permeability-barrier function.
Less water loss.Topical 2% niacinamide reduced transepidermal water loss (TEWL) in atopic dry skin, outperforming a white-petrolatum control.
Delivery synergy.The lipid carrier echoes the barrier’s own chemistry — ceramides, free fatty acids and cholesterol arranged in lamellae.

Tanno O et al. Br J Dermatol. 2000;143(3):524–531. · Soma Y et al. Int J Dermatol. 2005;44(3):197–202. · Brick-and-mortar schematic: PuriPharm.
An active that builds barrier lipids — delivered in a carrier built from barrier-like lipids.
04 · ACTIVE BIOLOGY
Brightening — blocking melanosome transfer
A downstream mechanism.Niacinamide does not inhibit tyrosinase; it acts on pigment distribution — the transfer of melanosomes from melanocytes to keratinocytes. In melanocyte–keratinocyte co-culture models, melanosome transfer was inhibited by 35–68%.
Reversible and cell-safe.The inhibition is reversible and non-cytotoxic — physiological tone modulation, not melanocyte toxicity.
Clinically visible.After 4 weeks of use, hyperpigmentation was significantly reduced and skin brightness improved versus vehicle control.
Hakozaki T et al. Br J Dermatol. 2002;147(1):20–31. · Greatens A et al. Exp Dermatol. 2005;14(7):498–508.
Split-face randomized controlled trial in melasma (n = 27, 8 weeks)

Navarrete-Solís J et al. Dermatol Res Pract. 2011;2011:379173. Depigmenting efficacy comparable to hydroquinone, with fewer adverse effects.
Tone correction that respects melanocyte biology.
04 · ACTIVE BIOLOGY
Anti-aging — energy, elasticity, even tone
The key aging study
Design.Double-blind, left–right randomized split-face trial; 50 women with clinical signs of photoaging; 5% niacinamide versus vehicle, twice daily for 12 weeks; imaging and instrumental measurements every 4 weeks.
Mechanistic basis.NAD+/NADP+ coenzymes sustain cellular energy and repair; antioxidant defense counters the protein glycation linked to sallow tone; epidermal renewal is supported for refined texture.
Endpoints significantly improved
Fine lines & wrinkles · hyperpigmented spots · red blotchiness · skin sallowness · elasticity (cutometry)
All endpoints significant versus vehicle control.

One gentle active improving five signs of facial aging.
04 · ACTIVE BIOLOGY
Sebum, pores and acne-prone skin
Sebum regulation.2% niacinamide significantly lowered sebum excretion rate after 2–4 weeks (Japanese cohort) and reduced skin-surface sebum after 6 weeks (Caucasian cohort).
Pore appearance.Less sebum output means less follicular distension — the mechanical driver of enlarged pores.
Acne-prone skin.4% niacinamide gel showed anti-inflammatory efficacy comparable to 1% clindamycin gel in moderate inflammatory acne — without antibiotic-resistance concerns.
Draelos ZD et al. J Cosmet Laser Ther. 2006;8(2):96–101. · Shalita AR et al. Int J Dermatol. 1995;34(6):434–437.
Double-blind randomized controlled trial in inflammatory acne (n = 76, 8 weeks)

Shalita AR et al. Int J Dermatol. 1995;34(6):434–437. No statistically significant difference between groups — equivalent efficacy.
Oil control and soothing — without the antibiotic route.
04 · ACTIVE BIOLOGY
Soothing and skin resilience
Barrier improvement and anti-inflammatory activity converge here — niacinamide matters as much for reactive, redness-prone skin as for aging or oily skin.
Red blotchiness — after 12 weeks of topical 5% niacinamide, facial red blotchiness was significantly reduced.
Bissett et al. Dermatol Surg. 2005
Rosacea-prone skin — a niacinamide-containing facial moisturizer improved barrier function and clinical signs in these subjects.
Draelos et al. Cutis. 2005;76(2):135–141
Inflammatory-cell infiltrate — topical 4% niacinamide reduced mast-cell infiltrate and improved solar elastosis in melasma-skin histology.
Navarrete-Solís et al. Dermatol Res Pract. 2011
Stress signaling — mitigates environment-induced, senescence-associated inflammatory signaling in epidermal keratinocytes.

Oxidative defense — supports endogenous antioxidant capacity via NADPH-linked redox pathways.

06 · DELIVERY SCIENCE
Why lipid delivery matters

A note on the evidence
This page presents platform-level vesicle literature — the delivery rationale behind the engineering of NanoActive OleoNia™, not product-specific measurements.
Vesicle–skin interaction — phospholipid vesicles adsorb onto and intermix with stratum-corneum lipid domains, promoting intimate carrier–skin contact.
Bouwstra JA, Honeywell-Nguyen PL. Adv Drug Deliv Rev. 2002;54(Suppl 1):S41–S55
Size determines depth — liposome particle size directly influences dermal delivery depth; smaller vesicles deposit their payload into deeper skin layers.
Verma DD et al. Int J Pharm. 2003;258(1–2):141–151
The follicular reservoir — particulate carriers preferentially accumulate in hair follicles, persisting far longer than on the skin surface and extending local availability.
Lademann J et al. Eur J Pharm Biopharm. 2007;66(2):159–164
Delivery engineering turns a soluble molecule into a depositable active.
06 · DELIVERY SCIENCE
Stability and formulation advantages
The fragility of free niacinamide
· Amide hydrolysis: converts to nicotinic acid under acidic pH and heat — causing transient flushing and stinging
· Direct, unprotected contact with reactive co-ingredients in the water phase
· Crystallization and local concentration gradients in low-water systems
The engineered response
· A compartmentalized core isolates the active from the continuous phase
· The lipid microenvironment buffers interfacial pH exposure at the molecular scale
· Uniform dispersion eliminates crystallization pathways
· A structural barrier against oxidation and interfacial stress during storage

The occlusive effect.Fine lipid carriers form a closely adherent film on the skin surface, reducing evaporative water loss and supporting stratum-corneum hydration — a further formulation-level delivery advantage. Image: PuriPharm technical library.

07 · FORMULATION CONCEPT
From “passive oils” to “active lipid systems”

08 · SCALP & HAIR
Scalp and hair — niacinamide beyond the face
Scalp is skin.Barrier-lipid synthesis, sebum dynamics and oxidative stress follow the same biology as facial skin — exactly what niacinamide targets.
Follicular targeting.Particulate carriers preferentially deposit in hair follicles and persist as long-lived reservoirs — a natural entry route for oil-based scalp products.
Follicle-cell evidence.In cultured human dermal papilla cells, niacinamide lowered oxidative-stress markers and down-regulated DKK-1, a signal associated with follicle regression (in vitro).
Honest evidence positioning.Facial benefits are clinically established; scalp-specific benefits are mechanistic and still emerging — a credible basis for “barrier-first” scalp care, not a hair-growth claim.
