The Wellness Shop Unseen Sunscreen

DESCRIPTION

What It Does: Provides a dry, weightless application vehicle that evaporates cleanly leaving actives and non-volatile silicones deposited on skin — eliminating the residual heaviness of conventional liquid carrier solvents.

Why It's Used: Cyclosiloxanes are the unique volatile silicone solvents that dissolve non-volatile silicones (dimethicone, cyclomethicone), organic uv filters, and lipophilic actives, providing the sensory-superior dry-touch application experience in premium formulations.

How It Works: Cyclosiloxane vapour pressure (d5 cyclopentasiloxane ~0.3 mmhg at 25°c) provides clean evaporation at body temperature. the cyclic ring structure provides lower boiling point than equivalent linear dimethicone, enabling faster evaporation while the ring conformation maintains the silicone's low surface energy for smooth application.

DESCRIPTION

What It Does: Provides the specific b-vitamin's characteristic skin and hair benefits: brightening and barrier reinforcement (niacinamide), keratin structural support (biotin), deep conditioning humectancy (panthenol).

Why It's Used: B-vitamins operate through fundamental cellular biochemistry pathways — nad⁺ for niacinamide, carboxylase cofactor for biotin, coa synthesis for panthenol — providing multi-benefit activity from essential metabolic chemistry.

How It Works: Acts as coenzyme or substrate in essential metabolic pathways: niacinamide → nad⁺/nadp⁺ → ceramide synthesis, melanosome transfer inhibition; biotin → carboxylase → fatty acid synthesis for ceramide; panthenol → pantothenic acid → coa → lipid metabolism.

Typically Found In: Multi-function skin care,b-vitamin formulas

DESCRIPTION

What It Does: Niacinamide strengthens the skin barrier, reduces visible pore size, regulates sebum production, fades dark spots, and improves skin texture and tone.

Why It's Used: It is used because it addresses multiple skin concerns at once without irritation, making it suitable for all skin types. it is stable in formulations and pairs well with most other actives.

How It Works: Niacinamide inhibits the transfer of melanosomes (pigment packets) to skin cells, reducing hyperpigmentation. it also stimulates ceramide synthesis to strengthen the skin barrier and reduces inflammation by modulating cytokine activity.

Typically Found In: Serums,moisturizers,toners,cleansers,eye creams,sunscreens,primers

TECHNICAL DETAILS

Primary Category: Active ingredient – vitamin

Secondary Functions: Barrier repair,brightening,anti-inflammatory

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 2%–10% (typical: 5%; higher concentrations may cause flushing in some individuals)

SOURCING & ETHICS

Vegan Status: Yes – synthetically produced

Halal Status: Yes – synthetic origin

Source Notes: Commercially produced via synthesis from nicotinic acid or 3-cyanopyridine. no animal-derived sources used in cosmetic-grade niacinamide.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low; concentrations above 10% may cause temporary flushing in sensitive individuals

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: At concentrations >10%, some users experience niacin flush (transient redness/tingling). generally very well-tolerated.

Safe for Sensitive Skin: Yes – one of the best-tolerated actives for sensitive skin

SAFETY & COMPATIBILITY

Safety Profile: Extensively studied and considered very safe. ewg hazard score: 1. no significant systemic toxicity concerns at topical concentrations.

Works Well With: Retinol,peptides,ahas/bhas,hyaluronic acid,ceramides,zinc,vitamin c,spf

Avoid Combining With: High concentrations of vitamin c (ascorbic acid) may theoretically convert to niacin – use at different times if using pure l-ascorbic acid above 15%

SCIENTIFIC NOTE

Niacinamide is a precursor to nad+ and nadp+, coenzymes vital to cellular energy metabolism. its benefits for dna repair and mitochondrial function make it a key ingredient in anti-aging strategies.
