Ingredient review
Hydrolyzed Tomato Skin
INCI: Hydrolyzed Tomato Skin
A gentle, antioxidant-rich ingredient from tomato skins that helps protect skin from environmental stress while providing light hydration.
In plain English
Hydrolyzed tomato skin is made by breaking down tomato skins into smaller, water-soluble pieces that can be easily used in skincare. Tomatoes are rich in lycopene, a powerful antioxidant that helps neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. This ingredient also contains natural sugars and amino acids that help attract and hold moisture in the skin, making it a dual-action ingredient for protection and hydration.

Quick decision guide
Useful, but context matters
Hydrolyzed Tomato Skin 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 Hydrolyzed Tomato Skin.
- 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
A processed derivative of tomato skins, where the natural proteins and polysaccharides are broken down (hydrolyzed) into smaller, water-soluble components. This makes it easier for the skin to absorb and use the beneficial compounds, particularly lycopene and other carotenoids.
How it works
When applied to the skin, hydrolyzed tomato skin delivers antioxidants that neutralize free radicals generated by UV exposure and pollution. The hydrolyzed peptides and sugars also form a light film on the skin's surface, helping to reduce water loss (transepidermal water loss, or TEWL) and keep the skin feeling soft and hydrated.
Pros
Gentle antioxidant protection
Hydrolyzed tomato skin provides a mild, non-irritating way to defend skin against free radicals from sun and pollution, making it suitable for sensitive skin types.
Lightweight hydration
Unlike some heavy oils, this ingredient adds moisture without clogging pores or leaving a greasy residue, ideal for layering under makeup or sunscreen.
Cons and cautions
Modest antioxidant potency
Compared to concentrated antioxidants like vitamin C or ferulic acid, hydrolyzed tomato skin may offer less dramatic protection, so it's best used as part of a broader antioxidant strategy.
Limited research in skincare
While tomato-derived compounds are well-studied in nutrition, fewer peer-reviewed studies specifically examine hydrolyzed tomato skin's effects when applied topically in cosmetic formulations.
Best for
- People with normal to dry skin looking for gentle antioxidant protection
- Those with sensitive skin who want a low-irritation antioxidant option
Use caution if
- Individuals with a known allergy to tomatoes or nightshade plants should avoid this ingredient
Usage tips
Safety summary
Hydrolyzed tomato skin has a low irritation and comedogenic risk, making it safe for most skin types. As with any plant-derived ingredient, patch testing is recommended for those with known allergies to tomatoes or nightshade plants.
Research notes
Research on tomato-derived compounds, particularly lycopene, shows strong antioxidant activity in vitro and in some human studies. However, specific studies on hydrolyzed tomato skin in topical skincare are limited, and most evidence comes from general knowledge of tomato antioxidants.
Common label clues
- Typical concentration
- 0.5% to 5% of the formula
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU, with no specific restrictions beyond standard cosmetic ingredient regulations.
- Common uses
- Serums, Moisturizers, Anti-aging creams, Sunscreens
- Environmental note
- Using tomato skin byproducts helps reduce food waste and supports a circular economy in the beauty industry.
Good to know
- Hydrolyzed tomato skin is often derived from food industry byproducts, making it a more sustainable ingredient choice.
- The hydrolysis process makes the tomato compounds water-soluble, so they work well in gel-based and lightweight formulas.
