Ingredient review
Sodium Ursolate
INCI: Sodium Ursolate
Sodium Ursolate is a gentle plant-derived antioxidant that may help calm skin and fight signs of aging, but research is still early.
In plain English
Sodium Ursolate is a salt form of ursolic acid, a compound found in plants like rosemary and apples. In skincare, it works as an antioxidant to protect skin from environmental damage and as an anti-inflammatory to soothe irritation. Think of it as a gentle helper that supports your skin's natural defenses, though it's not as well-studied as more common ingredients like vitamin C or niacinamide.

Quick decision guide
Useful, but context matters
Sodium Ursolate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Ursolate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Sodium Ursolate is the sodium salt of ursolic acid, a naturally occurring triterpenoid found in many plants, including rosemary, thyme, and apple peels. It is created by neutralizing ursolic acid with sodium hydroxide, making it more water-soluble and easier to formulate into skincare products.
How it works
In a cosmetic product, Sodium Ursolate works primarily as an antioxidant, neutralizing free radicals that can damage skin cells and accelerate aging. It also has anti-inflammatory effects, helping to reduce redness and swelling. Some early research suggests it may support collagen production and inhibit enzymes that break down collagen, but these effects are not yet confirmed in human skin.
Pros
Gentle antioxidant
Sodium Ursolate provides antioxidant protection without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.
Calming properties
Its anti-inflammatory action can help reduce redness and soothe skin after sun exposure or other irritants, offering a dual benefit in one ingredient.
Cons and cautions
Limited research
Most studies on ursolic acid are lab-based or on animals; human skin studies are scarce, so its real-world benefits are not fully proven.
Lower potency
As a salt form, Sodium Ursolate may be less potent than ursolic acid itself, and it may require higher concentrations to achieve noticeable effects.
Best for
- People looking for a gentle antioxidant to add to their routine
- Those with sensitive or reactive skin who want anti-aging support
Use caution if
- Individuals with known allergies to ursolic acid or related plant compounds
Usage tips
Safety summary
Sodium Ursolate is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic risk, but individuals with plant allergies should patch-test first. Avoid use on broken or damaged skin.
Research notes
Research on Sodium Ursolate is emerging. In vitro and animal studies show antioxidant and anti-inflammatory effects, and some suggest collagen-supporting activity. However, robust human clinical trials are lacking, so evidence is preliminary.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Sodium Ursolate is not specifically regulated by the FDA as a cosmetic ingredient, but it is generally considered safe for topical use in concentrations typical for cosmetics.
- Common uses
- Anti-aging serums, Soothing creams, Acne treatments
- Environmental note
- Sourcing from plant materials like rosemary or apple peels is generally sustainable, but check for organic or responsibly harvested sources if environmental impact is a concern.
Good to know
- Sodium Ursolate is often derived from rosemary or apple extracts, making it appealing for natural skincare fans.
- It is water-soluble, so it can be used in gel-based or lightweight formulas without oiliness.
