Arbutin

Bio-Activity Analysis
Tyrosinase Inhibition (Skin Whitening Effect)
SCIENTIFIC DATA VISUALIZATION
Health Benefits & Sources
Why You Need It
- Skin Brightening: Helps reduce the appearance of dark spots and hyperpigmentation.
- Antioxidant Protection: Fights free radicals that damage skin cells and cause premature aging.
- Urinary Tract Health: Acts as a mild antiseptic in the bladder (traditional use).
- Enzyme Inhibition: Stops the enzyme responsible for excess melanin production.
Deep Dive
Arbutin's superpower is its ability to inhibit tyrosinase, the enzyme your body uses to produce melanin (pigment). By temporarily 'turning down' this enzyme, it prevents new dark spots from forming while fading old ones. Unlike pure hydroquinone, Arbutin releases slowly, effectively whitening the skin without the risk of irritation or 'unwanted white spots' (leukoderma).
Natural Food Sources
While cosmetic Arbutin is extracted from Bearberry, dietary Arbutin is found in the skin and seeds of certain fruits. However, concentrations in food are generally low compared to what is used for skin benefits.
| Food | Amount | % DV |
|---|---|---|
| Bearberry (Uva Ursi) | Very High | N/A |
| Pear Skin | Moderate | ~2% |
| Wheat Sprouts | Moderate | ~1% |
| Cranberries | Low | <1% |
Supplementation
Dietary Use: Often found in 'detox' or urinary support blends (usually 300-600mg daily). Skin Care: Usually applied topically (serums/creams) at 1-7% concentration for maximum effect.

Safety & Side Effects
Arbutin is generally considered safe for topical and oral use in moderate amounts. Important: Because it metabolizes into hydroquinone, high oral doses should be cycled (e.g., 2 weeks on, 1 week off) to avoid strain on the liver. Pregnant or breastfeeding women should avoid concentrated supplements. Those with kidney disease should consult a doctor before using Uva Ursi or Arbutin supplements.
