Ingredient review
Gallium Maltolate
INCI: Gallium Maltolate
Gallium maltolate is an experimental ingredient with promising antimicrobial and anti-inflammatory properties, but it is not yet widely used or proven safe in everyday skincare.
In plain English
Gallium maltolate is a man-made compound that combines the metal gallium with maltol, a natural flavor enhancer. In lab studies, it has shown the ability to fight certain bacteria and reduce inflammation, which could be useful for acne or other skin conditions. However, it is still very new to cosmetics, and there is not enough research to confirm its safety or effectiveness in regular skincare products.

Quick decision guide
Read the cautions before using
Gallium Maltolate can be useful, but watch for some irritation potential.
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 Gallium Maltolate.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
Gallium maltolate is a coordination complex of gallium (a metal) and maltol (a naturally occurring compound found in some plants). It is synthesized in a lab and has been studied primarily for medical applications, such as treating infections and inflammation.
How it works
In skincare, gallium maltolate is thought to work by disrupting bacterial iron metabolism, which can inhibit the growth of certain bacteria (like Cutibacterium acnes, linked to acne). It may also reduce inflammation by modulating immune responses, potentially calming redness and swelling.
Pros
Antimicrobial potential
May target acne-causing bacteria without the dryness or irritation of traditional treatments like benzoyl peroxide.
Anti-inflammatory properties
Could help calm redness and swelling associated with breakouts or skin conditions.
Cons and cautions
Lack of cosmetic safety data
There are no long-term studies on gallium maltolate in skincare, so its safety for repeated use is unknown.
Potential for irritation
As a metal compound, it may cause stinging, redness, or allergic reactions, especially on sensitive skin.
Best for
- People with acne looking for alternative antimicrobial ingredients
- Those interested in cutting-edge, experimental skincare
Use caution if
- Anyone with sensitive or reactive skin
- Pregnant or nursing individuals (due to lack of safety data)
Usage tips
Safety summary
Gallium maltolate is an experimental ingredient with promising lab results but very limited safety data for cosmetic use. It may cause irritation or allergic reactions, and its long-term effects are unknown. Caution is advised.
Research notes
Research on gallium maltolate is primarily in medical contexts (e.g., antimicrobial and anti-inflammatory effects). A few studies show it can inhibit Cutibacterium acnes and reduce inflammation, but no peer-reviewed cosmetic safety or efficacy studies exist.
Common label clues
- Typical concentration
- Not established for cosmetics; typically studied at low percentages (e.g., 0.1–1%) in research
- Regulatory status
- Not specifically regulated as a cosmetic ingredient in the US or EU; no established safety assessment by the Cosmetic Ingredient Review (CIR) panel.
- Common uses
- Experimental skincare formulations
- Environmental note
- Gallium is a rare metal, and its mining and processing can have environmental impacts. However, the amounts used in cosmetics would be very small.
Good to know
- Gallium maltolate is not approved by the FDA for cosmetic use; it is still considered experimental.
- Maltol is a common flavor enhancer in foods, but gallium is a metal not typically found in skincare.
