Ingredient review
Zinc Linolenate Hydroxide
INCI: Zinc Linolenate Hydroxide
A gentle zinc-based ingredient that helps condition skin and may offer mild oil-control benefits without common irritation.
In plain English
Zinc Linolenate Hydroxide is a combination of zinc and linolenic acid (an omega-3 fatty acid). In skincare, it works as a mild astringent, meaning it can help tighten pores and reduce excess oil, while also providing some conditioning to keep skin feeling soft. It is generally well-tolerated and less drying than traditional zinc compounds like zinc oxide.

Quick decision guide
Useful, but context matters
Zinc Linolenate Hydroxide 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 Linolenate Hydroxide.
- 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
A semi-synthetic compound formed by reacting zinc with linolenic acid, creating a salt that is used in cosmetics for its skin-conditioning and mild astringent properties.
How it works
When applied to the skin, Zinc Linolenate Hydroxide gently binds to surface proteins and lipids, helping to temporarily tighten the skin's surface (astringent effect) and reduce the appearance of pores. It also provides a light film that can help retain moisture and soothe minor irritation.
Pros
Gentle oil control
Unlike harsh astringents like alcohol, Zinc Linolenate Hydroxide reduces shine and tightens pores without stripping the skin's natural moisture barrier.
Skin conditioning
The linolenic acid component provides essential fatty acids that help maintain skin softness and suppleness, making it suitable for daily use.
Cons and cautions
Limited research
There are few peer-reviewed studies specifically on Zinc Linolenate Hydroxide, so its long-term benefits and safety profile are not as well-established as more common ingredients.
Potential for dryness
Although milder than many astringents, it can still cause dryness or tightness in those with already dry or sensitive skin, especially if used in higher concentrations.
Best for
- People with oily or combination skin looking for gentle oil control
- Those with enlarged pores who want a mild astringent without harsh alcohol
Use caution if
- Individuals with very dry or compromised skin barriers, as astringents may exacerbate dryness
Usage tips
Safety summary
Zinc Linolenate Hydroxide is generally recognized as safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, but individuals with very dry or sensitive skin should patch test first.
Research notes
Research on Zinc Linolenate Hydroxide is limited. Most evidence comes from general knowledge of zinc salts and linolenic acid, which are both well-studied individually. More studies are needed to confirm its specific benefits and long-term safety.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets as a skin-conditioning agent. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Serums, Acne treatments
- Environmental note
- Zinc compounds can accumulate in aquatic environments, but the concentrations used in cosmetics are very low and considered safe when rinsed off.
Good to know
- Zinc Linolenate Hydroxide is often found in formulations targeting oily or acne-prone skin.
- It is considered a milder alternative to zinc oxide in some leave-on products.
