What Is Hydrolyzed Morus Alba Leaf Extract?
Hydrolyzed Morus Alba Leaf Extract comes from the leaves of the white mulberry tree, Morus alba, a plant long valued in Asia for sericulture and traditional skincare. The “hydrolyzed” part means the large leaf proteins and polysaccharides have been broken down through acid or enzymatic hydrolysis into smaller, water-soluble fragments. These lighter molecules absorb more easily into cosmetic formulas and onto skin, making the extract especially useful for hydration.
The process starts with harvested mulberry leaves that are cleaned, dried and milled into a fine powder. The powder is then mixed with water and treated with food-grade acid or specific enzymes that cut the large molecules into smaller pieces. After filtration and concentration the liquid is dried or kept as a solution, ready for use in personal care products.
The ingredient first appeared in modern cosmetics as companies searched for plant-based hydrators that could rival synthetic humectants. Its natural origin, long cultural history and mild profile helped it gain popularity in Korean and Japanese beauty products before spreading worldwide.
Today you will most often see Hydrolyzed Morus Alba Leaf Extract in moisturizers, hydrating toners, sheet masks, soothing gels, anti-aging serums and after-sun treatments, where it teams up with other humectants to keep skin comfortably moist.
Hydrolyzed Morus Alba Leaf Extract’s Cosmetic Benefits/Uses
This leaf-derived humectant offers a straightforward benefit in skincare.
As a humectant it attracts and binds water from the environment and from deeper skin layers, increasing the moisture content of the outer skin surface. Better hydration can leave skin feeling softer and looking plumper which in turn can improve the appearance of fine lines and dullness. Its plant origin and gentle nature also make it a good choice for formulas aimed at sensitive or daily use.
Who Can Use Hydrolyzed Morus Alba Leaf Extract
This ingredient suits most skin types. Its water-binding action benefits dry, normal and combination skin by adding lightweight moisture. Oily and acne-prone skin usually tolerates it well too, as long as the finished product is formulated in a non-greasy base. Sensitive skin tends to like its gentle plant origin.
Hydrolyzed Morus Alba Leaf Extract is solely derived from mulberry leaves with no animal input so it is appropriate for both vegetarians and vegans.
Current research shows no specific risks for pregnant or breastfeeding women when the extract is used topically in cosmetic amounts. Even so this is not medical advice and anyone who is pregnant or nursing should check with a healthcare professional before adding new products to their routine, just to stay on the safe side.
The extract does not make skin more prone to sunburn and has no known interactions with sunlight. It can be used morning or night without extra sun precautions beyond the usual daily SPF.
Potential Side Effects/Adverse Reactions
Reactions to topical Hydrolyzed Morus Alba Leaf Extract differ from person to person. The points below cover possible but uncommon effects. In properly made products the average user will not notice any of these issues.
- Mild redness or stinging – rare and usually short-lived if it occurs
- Itchiness – more likely if someone is already prone to plant allergies

If any of these reactions appear discontinue use and seek advice from a qualified healthcare professional.
Comedogenic Rating
Rating: 0 / 5
Hydrolyzed Morus Alba Leaf Extract is a water-soluble, plant based humectant with no oily or waxy components. It sits on the skin surface only long enough to pull in moisture then evaps or rinses away easily, leaving no clogging residue. Because it lacks heavy lipids or occlusive agents, it gets the lowest comedogenic score.
Suitable for acne-prone or breakout-prone skin.
No extra concerns related to pore clogging have been reported in the literature or by formulators.
Summary
Hydrolyzed Morus Alba Leaf Extract works mainly as a humectant. Its smaller, hydrolyzed molecules draw water to the skin surface, boosting hydration which can soften rough patches and make fine lines look less obvious. The ingredient is moderately popular in K-beauty style toners, gels and masks but is still a niche choice compared with glycerin or hyaluronic acid.
Topically it is considered very safe with low irritation risk and virtually no comedogenicity. As with any new skincare product it is wise to do a quick patch test before regular use, especially for very sensitive skin.
