What Is Glycine Tomentella Root Extract?
Glycine Tomentella Root Extract comes from the roots of Glycine tomentella, a climbing legume related to the soybean. The roots are naturally rich in polyphenols, isoflavones and other plant antioxidants that help protect the plant against stress. Long valued in East Asian herbal traditions, the root was first adopted by the beauty industry for its ability to guard skin against everyday damage caused by the environment.
To make the cosmetic grade extract, farmers harvest mature roots, then clean, dry and mill them into a coarse powder. The powder is soaked in a food grade solvent such as water or ethanol to pull out the active compounds. After filtration the liquid is concentrated and dried, leaving either a fluid extract or a fine brownish powder that can blend easily into creams, gels or serums.
You will typically see Glycine Tomentella Root Extract in antioxidant serums, anti-aging creams, daily moisturizers, sheet masks, after-sun lotions and city defense products aimed at countering pollution.
Glycine Tomentella Root Extract’s Cosmetic Benefits/Uses
This plant extract supports skin care formulas in two main ways:
- Antioxidant: The root’s polyphenols neutralize free radicals created by UV light, pollution and normal cell activity. By reducing oxidative stress the extract helps keep skin looking brighter and more even while also helping other delicate ingredients stay stable in the jar.
- Skin protecting: Formulas containing the extract form a light shield that limits the impact of external aggressors. Regular use can help maintain a healthy skin barrier which in turn supports softness and comfort throughout the day.
Who Can Use Glycine Tomentella Root Extract
The extract suits most skin types including normal, dry, combination and oily since it is lightweight and non-occlusive. Sensitive skin usually tolerates it well thanks to its soothing antioxidant profile, though anyone with a known legume or soybean allergy should approach with caution as the plant is a close relative of soy.
Because the ingredient is derived solely from plant roots and no animal derivatives or by-products are involved in its production, it is appropriate for vegans and vegetarians.
Current research shows no specific warnings for topical use during pregnancy or while breastfeeding. That said, the root does contain natural isoflavones, a class of phytoestrogens, so anyone who is pregnant or nursing should check with a healthcare professional before adding new products to their routine. This information is for educational purposes only and not medical advice.
The extract is not known to increase photosensitivity. Standard daytime sun protection practices remain advisable when using any skincare regimen.

Comedogenic Rating
Rating: 1 (very low likelihood of clogging pores)
Glycine Tomentella Root Extract is a water-soluble botanical with no heavy oils or waxes, so it rarely blocks pores. Its main components are polyphenols and isoflavones, which are lightweight and easily absorbed, leaving little residue on the skin.
This low rating means the extract is generally suitable for people who are prone to acne or breakouts.
No special concerns have been reported about the extract worsening blackheads or whiteheads, though the final product formula and other ingredients will always matter.
Summary
Glycine Tomentella Root Extract works as an antioxidant and skin-protecting agent. Its polyphenols mop up free radicals created by sunlight and pollution while also helping to keep the skin barrier comfortable and resilient.
The ingredient is still relatively niche compared with better-known plant extracts like green tea or vitamin C derivatives, but it is showing up more often in modern “urban defense” creams, serums and masks.
Overall it is considered safe for most users, with only rare reports of irritation or allergy linked to legume sensitivity. As with any new skincare ingredient it is wise to perform a quick patch test before full-face use just to be sure your skin agrees with it.
