What it is
Allantoin is a naturally soothing compound found in plants like comfrey, chamomile and sugar beet, though it can also be made synthetically for skincare. It’s been used for centuries to calm irritated skin, and today you’ll spot it in everything from face creams and serums to body lotions and hand washes.
Gentle, non-irritating and widely tolerated, allantoin is a staple ingredient for sensitive, stressed or damaged skin. If your skin ever feels tight, flaky or inflamed, allantoin is the kind of ingredient that quietly gets to work behind the scenes to make things feel better.
How it works in skincare
Allantoin supports skin health in three key ways: it soothes irritation, promotes healing, and improves hydration. First, it works as a calming agent, reducing discomfort and inflammation linked to dryness, eczema, shaving, or exposure to the elements.
Second, it supports the skin’s natural repair processes. Allantoin encourages cell regeneration, helping skin recover from minor damage. It’s why you’ll often find it in formulas for post-procedure care, after-sun lotions, or any product aimed at barrier recovery.
Finally, it acts as a moisturising agent; not by drawing in water like a humectant, but by softening and conditioning the skin’s surface. This helps smooth rough patches, reduce flaking, and improve texture over time.
In hand care and body care, allantoin is particularly helpful for dry, cracked or weather-worn skin. It’s non-greasy, non-comedogenic, and plays well with other ingredients like urea, ceramides and glycerin – making it a quiet but powerful addition to any restorative formula.
If you’re building a routine for sensitive skin or supporting your barrier after treatment or flare-up, allantoin is one of those ingredients that makes everything feel just that little bit kinder.
