Ingredient review
Calcium Fructoborate
INCI: CALCIUM FRUCTOBORATE
A mineral-derived complex that may help calm skin and fight free radicals, but research in cosmetics is still early.
In plain English
Calcium Fructoborate is a combination of calcium, the sugar fructose, and the trace mineral boron. In skincare, it's used as an antioxidant to help protect skin from environmental damage and as a soothing ingredient to calm irritation. Think of it as a gentle helper that supports your skin's natural defenses, though it's not as widely studied as more common antioxidants like vitamin C.

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 Calcium Fructoborate.
- 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
Calcium Fructoborate is a semi-synthetic compound formed by binding calcium and boron to fructose. It is often marketed as a bioavailable source of boron for dietary supplements, but in cosmetics it is used for its antioxidant and anti-inflammatory potential.
How it works
In a cosmetic product, Calcium Fructoborate is thought to neutralize free radicals (unstable molecules that can damage skin cells) and reduce the production of inflammatory signals in the skin. This may help calm redness and support a more even skin tone over time.
Pros
Gentle on skin
Calcium Fructoborate has a low irritation and comedogenic risk, making it suitable for sensitive skin types.
Dual action
It offers both antioxidant and anti-inflammatory benefits, which can help protect and calm the skin simultaneously.
Cons and cautions
Limited research
Most studies on Calcium Fructoborate focus on oral supplementation for joint health, not topical skincare. Its cosmetic benefits are not yet well-established.
Less common
This ingredient is not widely used in mainstream skincare, so finding products that contain it may be difficult.
Best for
- People with sensitive or easily irritated skin looking for a gentle antioxidant
- Those interested in trying newer, less common skincare ingredients
Use caution if
- Anyone with a known allergy or sensitivity to boron or calcium compounds
Usage tips
Safety summary
Calcium Fructoborate is considered safe for topical use at typical concentrations. It has low irritation and comedogenic potential. However, long-term safety data specific to cosmetic use is limited.
Research notes
Research on Calcium Fructoborate in skincare is emerging. Most evidence comes from oral supplement studies for bone and joint health. A few in vitro studies suggest antioxidant and anti-inflammatory activity, but human clinical trials on skin are lacking.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Generally recognized as safe for use in cosmetics in the EU and US, though not specifically approved as a cosmetic active ingredient.
- Common uses
- Anti-aging serums, Moisturizers, Eye creams
- Environmental note
- Boron is a naturally occurring element, but mining and processing can have environmental impacts. The small amounts used in cosmetics are unlikely to cause significant harm.
Good to know
- Calcium Fructoborate is sometimes listed as a 'mineral complex' on labels.
- It is stable in most formulations and does not require special packaging like some antioxidants.
