What Is Ipomoea Batatas Root Lees Extract?
Ipomoea Batatas Root Lees Extract comes from the humble sweet potato. After sweet potatoes are processed for food or fermentation, a residue called “lees” remains. Rather than discarding this nutrient-packed by-product, manufacturers collect the lees and transform them into a skin-friendly cosmetic ingredient. The extract is rich in natural sugars, amino acids, vitamins, and a touch of antioxidant phenolic compounds, all of which help it act as a softening agent on skin.
The idea of using sweet potato leftovers in beauty formulas grew out of the broader trend of upcycling plant waste to reduce environmental impact. Laboratories discovered that the lees had an impressive ability to smooth and condition the skin, so they began refining it for creams and lotions. Production usually involves washing and drying the lees, milling them into a fine powder, then soaking the powder in water or a gentle glycol to pull out the beneficial components. The liquid is filtered, concentrated, and preserved, leaving a mild, plant-based extract ready for use.
You will most often see Ipomoea Batatas Root Lees Extract in daily moisturizers, rich body butters, hand creams, soothing masks, after-sun lotions, and baby-care products where a gentle touch is essential.
Ipomoea Batatas Root Lees Extract’s Cosmetic Benefits/Uses
This ingredient is prized for one main role in skincare:
Emollient: As an emollient, Ipomoea Batatas Root Lees Extract helps soften and smooth the skin’s surface. It fills in tiny gaps between skin cells, creating a silkier feel and reducing the rough texture that can make skin look dull. By forming a lightweight, breathable layer, it also helps slow water loss, which keeps skin comfortably hydrated throughout the day. Because it is plant-derived and gentle, it fits well in formulas aimed at sensitive or dry skin.
Who Can Use Ipomoea Batatas Root Lees Extract
Because it works mainly as a gentle skin softener, Ipomoea Batatas Root Lees Extract suits dry, normal and combination skin types looking for extra comfort and smoothness. Oily or acne-prone skin can use it too since the extract feels light and is not known to clog pores, though those users may prefer it in lotions rather than rich balms.
The extract is completely plant based so it fits vegan and vegetarian lifestyles without issue. No animal-derived substances are involved in its sourcing or processing.
Current research shows no special risks for women who are pregnant or breastfeeding when the extract is applied to skin. Still, this article is not medical advice and anyone expecting or nursing should check with a healthcare professional before adding new products.
Ipomoea Batatas Root Lees Extract does not increase photosensitivity, so daytime use does not require extra sun precautions beyond a normal broad-spectrum sunscreen.

Comedogenic Rating
Rating: 1/5
Ipomoea Batatas Root Lees Extract is mostly made up of water soluble sugars, amino acids and small amounts of lightweight humectants, none of which are known to block pores. There is very little oil or wax content, so the likelihood of it trapping sebum under the skin is low. It is therefore considered practically non-comedogenic yet earns a 1 instead of 0 because any ingredient, if overused in a very rich formula, can contribute to congestion for extremely sensitive individuals.
For most people, including those prone to acne or breakouts, this ingredient is unlikely to cause clogged pores.
If a product also contains heavy butters or occlusive silicones, the overall formula could feel richer on the skin than the extract alone, so always consider the full ingredient list when shopping for acne friendly products.
Summary
Ipomoea Batatas Root Lees Extract is a plant based emollient that softens, smooths and lightly hydrates by filling microscopic gaps between skin cells and slowing water loss. Its natural mix of sugars, amino acids and antioxidants lets it create a breathable conditioning layer that leaves skin silky and comfortable.
While it is an up-and-coming ingredient rather than a mainstream staple, formulators appreciate its eco-friendly roots in upcycling sweet potato waste. You will mainly see it popping up in niche clean beauty lines, baby care lotions and a handful of sensitive skin creams.
Topical use is considered very safe with only rare reports of irritation or allergy. As with any new skincare product, perform a small patch test first to make sure your skin agrees with it before applying broadly.
