Skin Fx Superfood Firming Night cream, Best Night Cream for Glowing Skin, Night Cream for Men & Women, Best for Dry Skin & Pigmentation, 50 gm

DESCRIPTION

What It Does: Provides maximum aha efficacy from the smallest most penetrating alpha-hydroxy acid.

Why It's Used: The most potent aha — glycolic acid's smallest molecular size provides the deepest penetration and highest efficacy of any alpha-hydroxy acid for exfoliation and anti-aging.

How It Works: Smallest aha (mw 76) provides deepest stratum corneum penetration. disrupts corneodesmosomes reducing cohesion. stimulates fibroblast collagen i and iii synthesis. efficacy is ph-dependent — free acid fraction determines activity.

Typically Found In: Chemical peels,body lotions,anti-aging serums,exfoliating toners

TECHNICAL DETAILS

Primary Category: Active ingredient – primary aha

Secondary Functions: Brightening,collagen stimulation

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 1%–10% cosmetic; higher professional

SOURCING & ETHICS

Vegan Status: Yes – synthetic or fermentation-derived

Halal Status: Yes

Source Notes: Fermentation-derived or synthetic. ph must be ≤4.0 for aha activity.

SKIN COMPATIBILITY

Irritancy Rating: 2/5 – low to moderate

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Photosensitizing – mandatory spf use. start at low frequency.

Safe for Sensitive Skin: Use with caution – spf required

SAFETY & COMPATIBILITY

Safety Profile: Eu cosmetics: max 10% leave-on, ph ≥3.5, mandatory sun protection advisory. professional peel concentrations regulated separately.

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

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

SCIENTIFIC NOTE

Glycolic acid's ph-dependent efficacy is critical: at ph 3.0 ~100% is in the free acid (membrane-permeable) form; at ph 3.5 ~70%; at ph 4.0 ~50%. the eu ph ≥3.5 requirement reduces free acid proportion, lowering efficacy but also reducing irritation — why professional peel concentrations at lower ph are far more active than equivalent cosmetic concentrations.

DESCRIPTION

What It Does: Provides potent antioxidant protection, activates anti-aging sirtuin pathways, and reduces inflammation.

Why It's Used: Premium anti-aging antioxidant targeting sirt1-mediated longevity pathways alongside strong direct antioxidant and anti-inflammatory activity.

How It Works: Direct free radical scavenging via hydroxystilbene phenolic groups. activates sirt1 deacetylase, promoting mitochondrial biogenesis and dna repair. inhibits nf-kb for anti-inflammatory effects. may block tyrosinase for mild brightening.

Typically Found In: Premium anti-aging serums,antioxidant complexes,anti-inflammatory products

TECHNICAL DETAILS

Primary Category: Active ingredient – stilbene antioxidant

Secondary Functions: Sirtuin activation,anti-inflammatory,longevity pathway

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%–1%

SOURCING & ETHICS

Vegan Status: Yes – plant-derived or synthetic

Halal Status: Yes

Source Notes: Extracted from japanese knotweed (polygonum cuspidatum), grape skins, or synthesized. trans-form is bioactive; cis-form less active.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Generally well-tolerated; rare reports of contact sensitization at high concentrations.

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

Resveratrol's sirt1 activation promotes mitochondrial biogenesis via pgc-1α, potentially reversing age-related mitochondrial dysfunction in skin cells – the same longevity pathway activated by caloric restriction in model organisms.
