What Is Dihydroquercetin?
Dihydroquercetin is a plant based flavonoid most often extracted from the wood of the Siberian larch tree, though it can also be sourced from onions, grapes and other fruits. Chemically it belongs to the flavanonol family and features several hydroxyl groups that let it interact easily with free radicals. While it has been studied for decades in food science, skin care brands began adding it to formulas in the early 2000s as awareness of antioxidant protection grew. Commercial production usually involves water or alcohol extraction from finely ground larch chips, followed by purification and spray drying to yield a light yellow powder that dissolves in water-alcohol blends. You will spot it in serums, anti-aging creams, day moisturizers, sheet masks and after-sun treatments where product developers want to shore up the formula’s defense against everyday environmental stress.
Dihydroquercetin’s Cosmetic Benefits/Uses
Its main job in skin care is as an antioxidant. By neutralizing free radicals created by UV light and pollution, dihydroquercetin helps slow the look of premature aging, supports a more even skin tone and protects delicate ingredients like vitamins from breaking down inside the bottle.
Who Can Use Dihydroquercetin
Dihydroquercetin is considered gentle enough for most skin types. Dry and mature skin appreciate its protective antioxidant boost while oily and combination complexions benefit from its lightweight, non-occlusive nature that will not feel greasy. Sensitive skin generally tolerates it well because it lacks fragrance and known irritants, though those with severe plant allergies should check the full ingredient list in case other botanicals are present.
The compound is sourced from plants and no animal-derived processing aids are required, making it suitable for vegans and vegetarians.
Current research has not flagged any special concerns for pregnant or breastfeeding women when the ingredient is applied topically. Still, this is not medical advice and expectant or nursing mothers should review any new skincare product with their healthcare provider.
Dihydroquercetin does not increase photosensitivity so users can apply it day or night. It can also be paired with common actives such as vitamin C or niacinamide without stability issues.
Potential Side Effects/Adverse Reactions
Responses to topical dihydroquercetin differ from person to person. The points below outline potential side effects, but these are uncommon when the ingredient is formulated and used correctly.
- Mild redness or warmth shortly after application
- Temporary stinging on very compromised or freshly exfoliated skin
- Allergic contact dermatitis in individuals sensitive to larch or similar plant compounds
- Eye irritation if the product accidentally migrates into the eyes
If any of these reactions occur discontinue use and seek guidance from a healthcare professional
Comedogenic Rating
Rating: 0 (non-comedogenic)
Dihydroquercetin is a small, water-friendly molecule that does not form an oily film on the skin or clog pores, which is why it earns the lowest score on the comedogenic scale. It sits lightly on the surface, delivers antioxidant activity, then rinses away without leaving residue. This makes it suitable for people who are prone to acne or breakouts.
Keep in mind the finished product still depends on the full formula. Heavy oils, waxes or rich butters paired with dihydroquercetin can raise the overall pore-clogging potential, so always consider the product as a whole.
Summary
Dihydroquercetin is mainly prized for its antioxidant power, mopping up free radicals created by sunlight and pollution before they can age the skin or degrade other active ingredients. By shielding cells and stabilizing formulas it supports a smoother, more even complexion over time.
While not as famous as vitamin C or green tea, dihydroquercetin has carved out a modest following in niche serums, after-sun gels and anti-aging creams where formulators want a gentle plant-based antioxidant that plays well with most actives.
The ingredient is generally safe for all skin types with side effects rarely reported. As with any new skincare product it is wise to perform a quick patch test first to confirm personal tolerance.
