Ingredients Details

Beta-glucan

Common Name(s): Beta-1,3/1,6-glucan,yeast beta-glucan,oat beta-glucan

CAS Number: 9041-22-9

DESCRIPTION

What It Does: Reduces inflammation, deeply hydrates, stimulates collagen synthesis, accelerates wound healing.

Why It's Used: Used in anti-aging, sensitive skin, post-procedure, and eczema care for multi-action anti-inflammatory, moisturizing, and regenerative benefits.

How It Works: Binds to dectin-1 and cr3 receptors on macrophages and keratinocytes activating tgf-beta and collagen synthesis pathways. also activates macrophage phagocytosis for wound healing. humectant from polysaccharide hydroxyl groups.

Typically Found In: Anti-aging serums,sensitive skin products,post-procedure care,eczema treatments

TECHNICAL DETAILS

Primary Category: Active ingredient โ€“ polysaccharide / immunomodulator

Secondary Functions: Immunomodulator,wound healing,collagen stimulation

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%โ€“5%

SOURCING & ETHICS

Vegan Status: Yes โ€“ yeast or oat-derived

Halal Status: Yes

Source Notes: Derived from saccharomyces cerevisiae yeast (1,3/1,6-linked) or avena sativa oats (1,3/1,4-linked). molecular weight affects penetration โ€“ lower mw for skin penetration vs high mw for surface hydration.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 โ€“ very low

Comedogenicity Rating: 0/5 โ€“ non-comedogenic

Sensitivity Concerns: Non-irritating; ideal for reactive and sensitive skin.

Safe for Sensitive Skin: Yes โ€“ particularly recommended for sensitive skin

SAFETY & COMPATIBILITY

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

Works Well With: Ceramides,panthenol,allantoin,hyaluronic acid,centella asiatica

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Yeast beta-1,3/1,6-glucan receptor binding to dectin-1 on keratinocytes activates tgf-beta1, the key pro-collagen cytokine, stimulating fibroblast collagen production. this makes beta-glucan one of the few non-retinoid, non-peptide ingredients with direct receptor-mediated collagen stimulation.

Betaine Salicylate

Common Name(s): Betaine salicylate,trimethylglycine salicylate

CAS Number: 24077-28-9

DESCRIPTION

What It Does: Provides bha exfoliation and pore clearing with improved gentleness vs free salicylic acid.

Why It's Used: Salicylic acid alternative for sensitive or reactive skin where standard bha causes excessive irritation; popular in korean skincare.

How It Works: Betaine salt form provides buffered release of salicylate ions, moderating the rate of keratolytic activity for gentler exfoliation vs free salicylic acid.

Typically Found In: Sensitive acne treatments,korean bha toners,gentle exfoliants

TECHNICAL DETAILS

Primary Category: Active ingredient โ€“ bha derivative

Secondary Functions: Anti-acne,pore clearing,gentle exfoliation

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.5%โ€“4%

SOURCING & ETHICS

Vegan Status: Conditional โ€“ betaine may be plant-derived

Halal Status: Yes

Source Notes: Synthetic via kolbe-schmitt reaction or from willow bark extract.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 โ€“ very low; gentler than free salicylic acid

Comedogenicity Rating: 0/5 โ€“ anti-comedogenic

Sensitivity Concerns: Can cause dryness, peeling. follow with moisturizer. not for use in pregnancy.

Safe for Sensitive Skin: Yes โ€“ preferred over salicylic acid for sensitive skin

SAFETY & COMPATIBILITY

Safety Profile: Safe at otc concentrations (0.5โ€“2%). avoid in pregnancy at high concentrations.

Works Well With: Niacinamide,zinc,hyaluronic acid,ceramides

Avoid Combining With: Multiple exfoliating acids simultaneously; avoid in pregnancy at high concentrations

SCIENTIFIC NOTE

Betaine salt modification provides buffered, slower release of salicylate ions compared to free salicylic acid, reducing peak irritant concentration at the skin surface while maintaining keratolytic and anti-acne efficacy.

Crithmum Maritimum Extract

Common Name(s): Crithmum maritimum extract

DESCRIPTION

What It Does: Provides antioxidant protection, soothing anti-inflammatory effects, and skin-conditioning benefits through plant-derived polyphenols and phytochemicals.

Why It's Used: Plant extracts concentrate bioactive phytochemicals evolved for environmental protection โ€” uv, microbial, and oxidative stressors โ€” that translate to skin benefits.

How It Works: Polyphenols (flavonoids, phenolic acids) inhibit nf-ฮบb-mediated inflammatory signaling, scavenge reactive oxygen species through electron donation, and chelate pro-oxidant metal ions to reduce oxidative skin damage.

Typically Found In: Serums,toners,moisturizers,masks,essences

TECHNICAL DETAILS

Primary Category: Botanical extracts

Secondary Functions: Antioxidant,anti-inflammatory

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1โ€“10%

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Plant-derived extract; no animal components.

SKIN COMPATIBILITY

Irritancy Rating: 1

Comedogenicity Rating: 0

Sensitivity Concerns: Low sensitization potential at recommended use concentrations.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.

Works Well With: Niacinamide,hyaluronic acid,vitamin c,ceramides

Avoid Combining With: Strong oxidizing agents

SCIENTIFIC NOTE

Plant secondary metabolites (flavonoids, terpenes, phenolic acids) are biosynthesized as defense compounds against uv, herbivores, and pathogens. their anti-inflammatory activity typically derives from competitive inhibition of cox-2 and 5-lox enzymes (ic50 1โ€“50 ยตm), while antioxidant activity involves single electron transfer (set) and hydrogen atom transfer (hat) mechanisms with structure-dependent rate constants.
