Calming Mask Pack 10 Sheets

DESCRIPTION

What It Does: Hyaluronic acid draws and locks moisture into the skin at multiple depths (surface and deeper layers depending on molecular weight), creating a plumping, smoothing, and hydrating effect.

Why It's Used: It is used because it is endogenous to human skin, making it exceptionally biocompatible and non-irritating. its unparalleled moisture-binding capacity makes it the most effective hydrating ingredient available.

How It Works: Ha binds water molecules through its many hydroxyl and carboxyl groups, creating a gel-like matrix. high molecular weight ha (>500 kda) hydrates the skin surface; low molecular weight ha (<50 kda) penetrates deeper to provide interior hydration.

Typically Found In: Serums,moisturizers,sheet masks,toners,eye creams,lip treatments,dermal fillers (injectable)

TECHNICAL DETAILS

Primary Category: Active ingredient – humectant/hydrator

Secondary Functions: Barrier repair,plumping,anti-aging

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%–2% (effective at very low concentrations; multi-weight ha provides superior results)

SOURCING & ETHICS

Vegan Status: Yes – biotechnology-derived (microbial fermentation of streptococcus equi or b. subtilis); vegan-certified versions widely available

Halal Status: Yes

Source Notes: Originally extracted from rooster combs; now predominantly produced via biotechnology (bacterial fermentation), which is vegan and more sustainable.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low; one of the gentlest skincare ingredients known

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: In very dry environments, high-molecular-weight ha on the surface can potentially draw moisture out of the skin if not sealed with an occlusive. apply to damp skin and seal with moisturizer.

Safe for Sensitive Skin: Yes – ideal for all skin types including rosacea, eczema, and post-procedure skin

SAFETY & COMPATIBILITY

Safety Profile: Exceptional safety profile. endogenous molecule – no toxicity concerns. ewg hazard score: 1. safe during pregnancy.

Works Well With: Virtually all ingredients; especially ceramides,glycerin,peptides,retinol (reduces irritation),niacinamide,vitamin c

Avoid Combining With: No significant incompatibilities; high concentrations of alcohol in a formula may reduce its efficacy

SCIENTIFIC NOTE

Hyaluronic acid naturally degrades in skin (half-life ~1–2 days). the skin produces it endogenously, but production decreases with age. multi-molecular-weight ha formulas provide hydration at both surface and deeper skin levels.

DESCRIPTION

What It Does: Panthenol deeply moisturizes skin and hair, soothes irritation, accelerates wound healing, strengthens the skin barrier, and improves hair elasticity and shine.

Why It's Used: It is used because it is exceptionally versatile, working in both skin and hair formulations. it is gentle enough for sensitive and post-procedure skin, and converts to the active vitamin b5 within the skin.

How It Works: Panthenol penetrates skin and hair, where it is oxidized to pantothenic acid (vitamin b5), a coenzyme a precursor essential to metabolism. in skin, it acts as a humectant and stimulates fibroblast proliferation. in hair, it coats the shaft, improving manageability.

Typically Found In: Moisturizers,serums,toners,after-sun products,wound healing products,shampoos,conditioners,hair masks,beard care

TECHNICAL DETAILS

Primary Category: Active ingredient – provitamin b5

Secondary Functions: Anti-inflammatory,wound healing,hair conditioning

DESCRIPTION

What It Does: Provides humectant moisture retention with antimicrobial preservative-boosting activity.

Why It's Used: The balanced multifunctional diol — pentylene glycol provides the ideal balance of humectancy and antimicrobial activity for clean beauty preservation systems with excellent sensory compatibility.

How It Works: C5 diol: longer chain than propylene glycol providing better antimicrobial activity but shorter than 1,2-hexanediol (slightly lower membrane activity). two oh groups provide humectant water binding. solvent for fragrances and some actives. synergistic with phenoxyethanol reducing required phenoxyethanol concentration.

Typically Found In: Clean beauty products,natural preservation systems,moisturisers

TECHNICAL DETAILS

Primary Category: Functional ingredient – multifunctional pentanediol

Secondary Functions: Tewl reduction,skin plumping

Application Areas:

Facial Skincare

SAFETY & COMPATIBILITY

Safety Profile: Excellent safety profile. ewg score: 1.

Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Pentylene glycol's position in clean beauty preservation is due to a regulatory quirk: 1,2-pentanediol is not classified as a preservative in eu cosmetics regulations (unlike phenoxyethanol which requires preservative listing), so it can provide antimicrobial activity while not requiring the 'contains preservative' designation — enabling cleaner labels in natural-positioned formulations.

DESCRIPTION

What It Does: Provides hyaluronic acid hydration in the most formulation-stable and compatible form.

Why It's Used: The standard form of ha used in cosmetics – more stable than free ha, better solubility, and equivalent skin hydration benefits.

How It Works: Sodium salt reduces the polyelectrolyte repulsion of ha chains, allowing better packing in formulations. on skin, sodium ions dissociate and the ha chain unfolds to its full water-binding conformation. provides full ha humectant and barrier benefits equivalent to free ha.

Typically Found In: Hydrating serums,toners,moisturizers,sheet masks,anti-aging products
