O3+ Volcano Scrub Normal To Oily Skin For Blackheads & Instant Brightening

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 – 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%–20% (effective range: 10–20%; ph must be below 3.5 for activity)

SOURCING & ETHICS

Vegan Status: Yes – 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 – low to moderate; low ph formulations can cause initial tingling or stinging, especially at concentrations above 15%

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Acidic ph can irritate sensitive or compromised skin barriers. highly unstable – 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 – start at lower concentrations (5–10%). 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) – synergistic antioxidant effect,ferulic acid – stabilizing and boosting,spf,hyaluronic acid,niacinamide (use at different times if concentrations are high)

Avoid Combining With: Retinol (use at separate times – 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.

DESCRIPTION

What It Does: Provides antioxidant protection from reactive oxygen species, reduces inflammatory cytokine production in skin, and conditions skin surface through the plant's secondary metabolite complex.

Why It's Used: Chosen for its natural origin narrative, traditional use heritage, and multi-functional phytochemical profile that supports several concurrent skin care claims from one ingredient.

How It Works: Polyphenols, terpenoids, and alkaloids in the extract scavenge ros via hydrogen atom transfer, inhibit nf-kb or cox-2 inflammatory pathways, and interact with skin surface proteins for conditioning.

Typically Found In: Botanical skin care,natural products

TECHNICAL DETAILS

Primary Category: Active ingredient – antioxidant

Secondary Functions: Free radical scavenging,anti-aging

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%–10%

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Plant-derived extract or synthetic.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Non-irritating; well-tolerated.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

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

Works Well With: Vitamin c,vitamin e,ferulic acid,spf,other antioxidants

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Plant secondary metabolites evolved as uv photoprotectants and antimicrobial agents — mechanisms that directly translate to cosmetic antioxidant and anti-inflammatory activity in human skin.

DESCRIPTION

What It Does: Exfoliates dead skin cells, attracts and retains moisture, brightens skin tone, and improves texture.

Why It's Used: Dual exfoliant and humectant – uniquely hydrating vs other ahas. gentler and suitable for normal-to-sensitive skin.

How It Works: Disrupts desmosomes to promote exfoliation at low ph. acts as humectant. also stimulates ceramide synthesis at lower concentrations for barrier support.

Typically Found In: Chemical exfoliants,toners,serums,professional peels

TECHNICAL DETAILS

Primary Category: Active ingredient – alpha hydroxy acid (aha)

Secondary Functions: Humectant,brightening,barrier support,ceramide synthesis

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 2%–10% (daily); 20%–90% (professional); active at ph ≤3.9

SOURCING & ETHICS

Vegan Status: Yes – synthetic or fermentation-derived

Halal Status: Yes

Source Notes: Fermentation-derived from carbohydrates or synthetically produced. both l-form and dl-form used.

SKIN COMPATIBILITY

Irritancy Rating: 2/5 – low to moderate

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Photosensitizing – spf required. better tolerated than glycolic acid for most skin types.

Safe for Sensitive Skin: Use with caution – spf required

SAFETY & COMPATIBILITY

Safety Profile: Safe at otc concentrations. eu: ≤10% leave-on at ph ≥3.5. mandatory spf advisory.

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

Avoid Combining With: Retinol in same step; multiple exfoliants simultaneously

SCIENTIFIC NOTE

Lactic acid's role as a natural moisturizing factor (nmf) component makes it uniquely hydrating among ahas. ceramide synthesis stimulation at 2% provides barrier benefits complementing exfoliating activity.
