Ingredient review
Hydrolyzed Conalbumin
INCI: Hydrolyzed Conalbumin
Hydrolyzed conalbumin is a gentle egg-derived protein that forms a light film on skin to help retain moisture and temporarily smooth fine lines.
In plain English
Hydrolyzed conalbumin is made by breaking down a protein found in egg whites into smaller pieces. When applied to skin, it leaves a thin, invisible layer that helps hold in moisture and makes the skin feel smoother. It is not a strong active ingredient but works as a supportive, soothing component in moisturizing and anti-aging products.

Quick decision guide
Useful, but context matters
Hydrolyzed Conalbumin 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 Conalbumin.
- 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
Hydrolyzed conalbumin is a protein derived from egg white (conalbumin, also called ovotransferrin) that has been broken down through hydrolysis into smaller peptides, making it easier for the skin to absorb and use.
How it works
In a cosmetic product, hydrolyzed conalbumin forms a flexible film on the skin's surface. This film reduces water loss (transepidermal water loss, or TEWL) and temporarily tightens the skin, giving a short-term smoothing effect. The peptides may also provide some antioxidant activity by binding iron, which can help protect skin from environmental stress.
Pros
Gentle moisture lock
Forms a light, breathable film that helps reduce water loss from the skin, making it a good option for dry or sensitive skin types.
Temporary smoothing effect
The film can give a short-term, visible smoothing of fine lines and texture, which is helpful before makeup or for a quick skin boost.
Cons and cautions
Limited research
There is very little published scientific evidence specifically on hydrolyzed conalbumin in skincare, so its long-term benefits are not well established.
Potential allergen
Since it is derived from egg white, it may cause allergic reactions in people with egg allergies, though the risk is low in well-processed cosmetic ingredients.
Best for
- People with dry or dehydrated skin looking for extra moisture retention
- Those who want a gentle, non-irritating film-forming ingredient in their routine
Use caution if
- Individuals with a known allergy to eggs or egg-derived ingredients
Usage tips
Safety summary
Hydrolyzed conalbumin is considered safe for topical use in cosmetics at typical concentrations. The main safety concern is for individuals with egg allergies, though the risk of a reaction is low due to the high degree of processing. Always patch test a new product if you have known sensitivities.
Research notes
Research on hydrolyzed conalbumin in skincare is very limited. Most evidence comes from general knowledge about egg proteins and film-forming agents. While it has plausible benefits for moisture retention and temporary smoothing, there are no large-scale clinical studies confirming its efficacy compared to other ingredients.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets as a safe ingredient when used as directed. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Anti-aging serums, Moisturizers, Eye creams
- Environmental note
- Egg-derived ingredients are a byproduct of the food industry, which can help reduce waste. However, sourcing and processing methods vary, so eco-conscious consumers may want to look for brands that disclose sustainable practices.
Good to know
- Hydrolyzed conalbumin is often listed alongside other egg-derived proteins like hydrolyzed egg white or hydrolyzed ovomucoid in ingredient lists.
- The hydrolysis process breaks the protein into smaller peptides, which may improve how well the skin can use it compared to whole egg white.
