Ingredient review
Donkey Milk
INCI: Donkey Milk
Donkey milk is a gentle, nutrient-rich moisturizer that may soothe sensitive skin, but scientific evidence for its cosmetic benefits is still limited.
In plain English
Donkey milk is a natural ingredient used in skincare products like moisturizers and soaps. It contains vitamins, minerals, and proteins that can help hydrate and soften the skin. Because it is similar in composition to human milk, it is often considered gentle and suitable for sensitive skin. However, most of the claims about its anti-aging or brightening effects come from traditional use rather than strong scientific studies.

What it is
Donkey milk is the milk produced by female donkeys. It has been used historically for its nutritional and skincare benefits, and in modern cosmetics it is valued for its moisturizing and soothing properties.
How it works
Donkey milk works as an emollient and humectant, meaning it helps soften the skin and also attracts moisture to the skin's surface. Its proteins and lipids may help support the skin barrier, while its natural sugars (like lactose) can gently exfoliate and hydrate.
Pros
Gentle on skin
Donkey milk has a low irritation risk and is often well-tolerated by sensitive skin types, making it a good choice for those who react to harsher ingredients.
Nutrient-rich
It naturally contains vitamins A, B, C, and E, along with minerals and proteins that can support skin hydration and softness.
Cons and cautions
Limited evidence
Most benefits are based on traditional use and anecdotal reports; there are few peer-reviewed studies confirming its cosmetic efficacy.
Not vegan-friendly
As an animal-derived ingredient, it is not suitable for those following a vegan lifestyle.
Best for
- People with dry or sensitive skin
- Those looking for a gentle, natural moisturizer
Use caution if
- Vegans
- Individuals with a known allergy to milk proteins
Usage tips
Safety summary
