Ingredient review
Zinc Glycinate
INCI: Zinc Glycinate
Zinc glycinate is a well-tolerated, chelated zinc that offers antioxidant protection and soothing benefits without the irritation of other zinc forms.
In plain English
Zinc glycinate is a form of zinc that is chemically bonded to the amino acid glycine. This bond makes it easier for your skin to absorb and use the zinc without irritation. In skincare, it acts as a gentle antioxidant that helps protect skin from environmental damage and can calm redness or sensitivity. Unlike some other zinc compounds, it is less likely to cause stinging or dryness, making it a good choice for sensitive or reactive skin.

Quick decision guide
Easy yes for most routines
Zinc Glycinate 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 Zinc Glycinate.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Zinc glycinate is a chelated mineral compound where zinc is bound to glycine, an amino acid naturally found in the body. This chelation improves stability and skin absorption compared to unbound zinc salts like zinc oxide or zinc sulfate.
How it works
Once applied, zinc glycinate releases zinc ions that can neutralize free radicals, support skin barrier function, and reduce inflammation. The glycine component helps the zinc penetrate the upper layers of skin more effectively, while also providing mild moisturizing and soothing effects.
Pros
Gentle on sensitive skin
Unlike zinc oxide or zinc sulfate, zinc glycinate is chelated, which reduces the chance of irritation, stinging, or dryness. This makes it suitable for those with rosacea, eczema, or easily irritated skin.
Better absorption for antioxidant effect
The glycine bond helps zinc penetrate the skin more effectively, potentially boosting its ability to neutralize free radicals and support skin repair compared to non-chelated zinc forms.
Cons and cautions
Less studied than other zinc forms
While zinc itself is well-researched, zinc glycinate in topical skincare has fewer clinical studies than zinc oxide or zinc PCA, so its long-term benefits are less documented.
Not a primary sunscreen ingredient
Zinc glycinate does not provide significant UV protection on its own, unlike zinc oxide. It is not a substitute for sunscreen, so you still need a dedicated SPF product.
Best for
- People with sensitive or reactive skin looking for a gentle antioxidant
- Those with mild acne or redness who want a soothing, non-drying zinc option
Use caution if
- Individuals with known zinc allergy (rare)
Usage tips
Safety summary
Zinc glycinate is considered safe for topical use in cosmetics at typical concentrations (0.1–1%). It has low irritation and comedogenic potential, making it suitable for most skin types. Allergic reactions are rare. Avoid contact with eyes and broken skin.
Research notes
Research on topical zinc glycinate is limited but promising. Studies on zinc in general support its antioxidant, anti-inflammatory, and wound-healing properties. The chelation with glycine may improve skin penetration and tolerability, but more human trials are needed to confirm specific benefits over other zinc forms.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Zinc glycinate is not specifically regulated as a cosmetic ingredient in the US or EU, but zinc compounds are generally recognized as safe for topical use. It is not a drug ingredient and does not require FDA approval for cosmetic use.
- Common uses
- Serums, Moisturizers, Sunscreens, Soothing treatments
- Environmental note
- Zinc is a naturally occurring mineral, and zinc glycinate is typically produced through a chemical reaction between zinc salts and glycine. Its environmental impact is low compared to some synthetic preservatives, but sourcing and manufacturing practices vary by supplier.
Good to know
- Zinc glycinate is often listed as 'Zinc Glycinate' or 'Zinc bisglycinate' on ingredient labels.
- It is generally considered safe for use during pregnancy and breastfeeding when used topically, but always consult a doctor for personal advice.
