Allantoin For Skin: A Comprehensive Guide

What is allantoin?

Why is allantoin used in topical skin products?

Why should you look for skin care products with allantoin as an ingredient? Allantoin is widely used because it’s non-toxic, safe, and highly effective at hydrating, soothing, and smoothing the skin³. All skin texture types need this, whether sensitive skin, oily skin, dry skin, irritated skin, or combination skin. You will find many products formulated with allantoin and other helpful ingredients like ceramides for your skin . If you’re wondering how to improve skin texture , consider using products with allantoin. Allantoin promotes skin health through the following benefits: Due to the hygroscopic nature of allantoin, it serves as a humectant, increasing the water uptake into the outer layers of skin. Allantoin has also been shown to reduce transepidermal water loss (TEWL), helping the skin retain its hydration from within. This hydration also serves to soothe dry, irritated skin⁴. Allantoin is a keratolytic agent, meaning it aids in the shedding of dead skin cells by thinning and softening keratin. This causes the cells to loosen and shed, which helps coax younger skin cells to the surface. The exchange of dead skin cells for healthy, youthful skin helps prevent infections from building a foothold as it also washes away any bacteria found in those outer layers of skin⁵. This younger undamaged skin also retains its water content more efficiently, thereby increasing how soft and smooth skin feels⁶. Because of its soothing properties, it's also good for hair care, especially for the scalp. Allantoin also aids in extracellular matrix synthesis and stimulates fibroblasts, producing collagen, a crucial compound for healthy skin. These two processes are key to the wound healing process, making allantoin helpful in reducing the time it takes for skin to heal. This is also what makes allantoin effective at reducing the visibility of scars⁷. One of the primary causes of wrinkles and fine lines is the decrease in collagen production that occurs with age, leading to decreased skin elasticity. Because allantoin effectively increases collagen production within the skin, it is a common ingredient for promoting healthy aging and skin elasticity⁸. Because allantoin is non-comedogenic and generally soothing and hydrating, all skin types can benefit from its usage, though those with drier skin may find it more useful. Additionally, allantoin has been reported to help those with mild to moderate eczema or acne-prone skin due to its hydration factor. Allantoin has strong soothing and hydrating capabilities, making it an effective compound for those with acne-prone skin, especially in combination with harsher ingredients commonly found in acne products. Allantoin can also help reduce the appearance of acne scarring due to its ability to stimulate fibroblast production. Finally, recent research has also shown that when compared to other acne treatments, allantoin is more effective at maintaining healthy aging for your skin by minimizing the dehydration associated with popular acne treatments¹⁰. Allantoin can be paired with many ingredients, as it’s largely unreactive, and due to its soothing properties, it can be used with harsher ingredients to lessen their irritation. For example, allantoin is often paired with retinol and ascorbic acid, two common ingredients known for causing irritation. You can also combine allantoin with other moisturizers (particularly silicone-based) to amplify the moisturizing effect on your skin (3). So, by using allantoin in conjunction with other ingredients, you can counteract its negative effects or boost its positives. Few other ingredients cover the range of benefits that allantoin does (i.e., hydration, smoothing, healing, and wrinkle prevention) all while having little to no side effects and being ethically sourced. That’s why OneSkin chose to use allantoin as one of the key ingredients in OS-01 FACE, a Topical Supplement that aims to promote skin health on the molecular level through a blend of other scientifically validated and ethically sourced ingredients.
