Lentils (scientific name: Lablab purpureus ) are climbing plants that belong to the legume family and have long been cultivated for food and medicinal purposes, mainly in Asia and Africa. In Japan, they are also known as Fujimame (Fuji beans), and the young pods and beans are used as food. The seeds and pods are rich in nutrients such as protein, polyphenols, and minerals.
Traditionally, lentils have been used to calm excess heat in the body, suppress inflammation, and treat skin problems. Recent basic research suggests that polyphenols and flavonoids derived from lentils may contribute to antioxidant and anti-inflammatory effects and skin barrier support . These properties make them promising for use as ingredients to maintain skin moisture, maintain skin clarity, and treat rough skin.
Additionally, plant-derived proteins and amino acids may support the natural moisturizing factors (NMF) in the stratum corneum, potentially contributing to maintaining skin condition in dry environments.
Characteristics of lentils

- Japanese name: Hiramame (Hydrangea bean)
- Origin: Africa to South Asia
- Growth form: Climbing annual plant
- Parts used: seeds, pods, young leaves
- Characteristics: Rich in protein and polyphenols
Main ingredients (reported examples)
- Polyphenols: Ferulic acid, caffeic acid derivatives
- Flavonoids: Quercetin, camphor derivatives
- Proteins and peptides: plant proteins, amino acids
- Polysaccharide: Water-soluble polysaccharide
- Vitamins: B vitamins, vitamin E

Expected effects (skin focus)
- Moisturizing and moisture retention support: It has been suggested that amino acids and polysaccharides may contribute to maintaining moisture in the stratum corneum and preventing dryness.
- Barrier function support effect: It has been suggested that this product may contribute to stabilizing the protective function of the skin surface and maintaining resistance to external stimuli.
- Antioxidant and anti-aging support effects: It has been suggested that it may contribute to suppressing oxidative damage caused by ultraviolet rays and environmental stress.
- Supports rough skin and inflammation care: It has been suggested that it may contribute to reducing redness, dryness, and irritation, as well as stabilizing skin condition.
- Supports transparency and even skin tone: It has been suggested that this may contribute to reducing dullness and maintaining a brighter appearance of the skin.
- Supports firmness and smoothness: It has been suggested that this may contribute to maintaining the integrity of the keratin structure and giving the appearance of smooth skin texture.
