Key Ingredients

L-Ascorbic Acid, Hyaluronic Acid Spheres

Ingredients Details

Ascorbic Acid

Common Name(s): Vitamin c,l-ascorbic acid,l-ascorbate

CAS Number: 50-81-7

DESCRIPTION

What It Does: Ascorbic acid neutralizes free radicals, stimulates collagen production, inhibits melanin synthesis for a brighter complexion, and supports skin repair.

Why It's Used: It is used because it offers comprehensive antioxidant and brightening benefits supported by extensive clinical evidence. it is the most bioavailable form of vitamin c for topical application.

How It Works: As an antioxidant, it donates electrons to neutralize reactive oxygen species. it is an essential cofactor for the hydroxylation of proline and lysine in collagen synthesis. it inhibits tyrosinase, the enzyme responsible for melanin production, reducing hyperpigmentation.

Typically Found In: Vitamin c serums,brightening moisturizers,antioxidant formulations,spf products,eye creams

TECHNICAL DETAILS

Primary Category: Active ingredient โ€“ vitamin c

Secondary Functions: Collagen booster,tyrosinase inhibitor,ph adjuster

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 5%โ€“20% (effective range: 10โ€“20%; ph must be below 3.5 for activity)

SOURCING & ETHICS

Vegan Status: Yes โ€“ synthetically produced or corn/plant-derived

Halal Status: Yes

Source Notes: Commercially produced by reichstein synthesis or guangxi fermentation process from glucose. some plant-derived versions exist.

SKIN COMPATIBILITY

Irritancy Rating: 2/5 โ€“ low to moderate; low ph formulations can cause initial tingling or stinging, especially at concentrations above 15%

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

Sensitivity Concerns: Acidic ph can irritate sensitive or compromised skin barriers. highly unstable โ€“ oxidizes rapidly when exposed to air, light, and heat (turns orange/brown). use in the morning under spf.

Safe for Sensitive Skin: Use with caution โ€“ start at lower concentrations (5โ€“10%). stabilized derivative forms (vitamin c derivatives) may be better tolerated.

SAFETY & COMPATIBILITY

Safety Profile: Very safe; well-studied. key concern is formulation stability, not safety. ewg hazard score: 1.

Works Well With: Vitamin e (tocopherol) โ€“ synergistic antioxidant effect,ferulic acid โ€“ stabilizing and boosting,spf,hyaluronic acid,niacinamide (use at different times if concentrations are high)

Avoid Combining With: Retinol (use at separate times โ€“ ph incompatibility),benzoyl peroxide (oxidizes vitamin c),ahas/bhas (cumulative irritation risk)

SCIENTIFIC NOTE

L-ascorbic acid is the only form of vitamin c that is proven bioactive in skin at the molecular level. its instability (rapid oxidation) has driven development of numerous stable derivatives including ascorbyl glucoside, magnesium ascorbyl phosphate, and ascorbyl tetraisopalmitate.

Coconut Alkanes

Common Name(s): Coconut alkanes,cosmetic active,functional ingredient

CAS Number: N/a

DESCRIPTION

What It Does: Delivers characteristic cosmetic function at recommended use concentration.

Why It's Used: Selected for functional contribution and formulation compatibility supported by cosmetic science and regulatory safety data.

How It Works: Works through the mechanism of its molecular class โ€” physicochemical or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed cosmetic literature.

Typically Found In: Skin care formulations

TECHNICAL DETAILS

Primary Category: Active ingredient โ€“ cosmetic active

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%โ€“10%

SOURCING & ETHICS

SKIN COMPATIBILITY

Irritancy Rating: 1/5 โ€“ very low

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

Sensitivity Concerns: Well-tolerated by most skin types.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ€“2.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Coconut alkanes has an established safety and efficacy profile within the cosmetic regulatory framework at standard use concentrations.

Ethylene/propylene/styrene/copolymer

Common Name(s): Ethylene/propylene/styrene/copolymer

DESCRIPTION

What It Does: Delivers targeted skin-conditioning or bioactive benefits through a specific mechanism of action suited to the formulation's intended purpose.

Why It's Used: Specialty actives address specific skin concerns through targeted molecular mechanisms, providing efficacy beyond what base formulation ingredients alone can achieve.

How It Works: The bioactive compound interacts with specific molecular targets in skin cells or the extracellular matrix โ€” enzymes, receptors, structural proteins, or signaling molecules โ€” triggering beneficial biological responses.

Typically Found In: Serums,treatments,moisturizers,specialty products

TECHNICAL DETAILS

Primary Category: Specialty actives

Secondary Functions: Skin-conditioning,anti-aging

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.01โ€“5%

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Specialty active ingredient; check individual sourcing for vegan status.

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,peptides

Avoid Combining With: Incompatible with oxidizing agents; check ph stability

SCIENTIFIC NOTE

Specialty actives typically work through enzyme inhibition (e.g., tyrosinase inhibition for brightening, mmp inhibition for anti-aging), receptor activation (e.g., retinoid receptors, ppar-ฮณ for barrier genes), or transcription factor modulation (e.g., nrf2 for antioxidant gene upregulation). structure-activity relationships determine potency and selectivity.
