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: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.

Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.

How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.

Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners

DESCRIPTION

What It Does: Provides skin surface hydration through hydroxyl group water binding, supports beneficial skin microbiome organisms as a selective fermentation substrate, and forms a conditioning film that reduces tewl.

Why It's Used: Natural polysaccharides combine humectant function with microbiome prebiotic activity — a dual benefit unavailable from synthetic humectants like glycerin, important for microbiome-conscious formulation.

How It Works: Hydroxyl groups on the polysaccharide backbone bind water through hydrogen bonding (5–7 h₂o molecules per sugar unit) providing hygroscopic moisture retention. fructans and inulins are selectively fermented by beneficial lactobacillus skin commensals providing a prebiotic microbiome benefit.
