Ingredient review
Hydrolyzed Eggshell Membrane
INCI: HYDROLYZED OVUM SHELL MEMBRANE
A natural, protein-packed ingredient that helps hydrate and support skin barrier function, with low irritation potential.
In plain English
Hydrolyzed eggshell membrane is made by breaking down the thin layer inside an eggshell into smaller, skin-friendly proteins. These proteins help attract and hold moisture to your skin, and they can form a light, breathable film that makes your skin feel smoother and more supple. Think of it as a gentle, natural helper for keeping your skin's barrier strong and hydrated.

Quick decision guide
Useful, but context matters
Hydrolyzed Eggshell Membrane 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 Eggshell Membrane.
- 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
Hydrolyzed eggshell membrane is a natural ingredient sourced from the thin membrane between the eggshell and the egg white. Through a process called hydrolysis, the membrane's proteins (including collagen, elastin, and glycoproteins) are broken down into smaller peptides that can be more easily absorbed by the skin.
How it works
When applied to the skin, the peptides from hydrolyzed eggshell membrane help attract water molecules, boosting hydration. They also form a thin, flexible film on the skin's surface that reduces water loss (transepidermal water loss, or TEWL — the amount of water that evaporates from your skin). This film can temporarily smooth fine lines and improve skin texture, while the amino acids support the skin's natural repair processes.
Pros
Natural moisture magnet
The peptides in hydrolyzed eggshell membrane attract water to the skin, helping to keep it hydrated and plump without a greasy feel.
Gentle barrier support
It forms a light film that reduces moisture loss, making it a good option for those with sensitive or compromised skin barriers.
Cons and cautions
Allergen consideration
Although the hydrolysis process reduces allergenic proteins, people with severe egg allergies may still want to patch test or avoid it.
Variable efficacy
The quality and effectiveness depend heavily on how the ingredient is processed, so not all products with this ingredient will perform the same.
Best for
- People with dry or dehydrated skin looking for extra moisture
- Those interested in natural, protein-based skincare ingredients
Use caution if
- Individuals with a known egg allergy should patch test first or consult a dermatologist
Usage tips
Safety summary
Hydrolyzed eggshell membrane is considered safe for topical use in cosmetics. It has a low irritation and comedogenic risk. However, individuals with egg allergies should exercise caution and perform a patch test before use.
Research notes
Studies suggest that hydrolyzed eggshell membrane can improve skin hydration and reduce fine lines when used consistently. Most evidence comes from in vitro and small clinical studies, indicating moderate support for its benefits.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Anti-aging serums, Moisturizers, Eye creams, Sheet masks
- Environmental note
- Using eggshell membrane helps reduce waste from the egg industry, as it is a byproduct that might otherwise be discarded.
Good to know
- Hydrolyzed eggshell membrane is often listed as 'Hydrolyzed Ovum Shell Membrane' on ingredient labels.
- It is a byproduct of the egg industry, making it a more sustainable ingredient choice.
