Allantoin was first separated in 1800 by the italian physician michele francesco buniva (1761– 1834) and the french chemist louis nicolas vauquelin, who mistakenly thought it to be present in the amniotic fluid. In 1821, the french chemist jean louis lassaigne discovered it in the fluid of the allantois; he called it “l’acide allantoique”. In 1837, the german chemists friedrich wöhler and justus liebig synthesized it from uric acid and relabelled it “allantoïn”.

Extracted from the root of the comfrey plant, allantoin is a non-irritating active ingredient that relieves and safeguards the skin. With the capability to assist recover the skin and promote the development of new tissue, it’s a fantastic all-rounder for keeping skin at the top of its video game.

In its natural type, allantoin is discovered in numerous plants, such as sugar beet, comfrey, chamomile, tobacco seed, and wheat sprouts. [3]

Mechanism of action

There is no well managed information that can officially corroborate the approach of action label. Nevertheless, ongoing studies recommend that there may exist a histological wound recovery profile caused by allantoin in rats that causes the amelioration and attachment of the reestablishment of typical skin. This assistance of wound recovery is supported by observations that wounds caused to rat subjects to which topical allantoin preparations were used histologically shown increased vasodilation, existence of inflammatory exudates, variety of inflammatory cells, angiogenesis, fibroblast expansion, and increased collagen deposition when compared to rat topics with wounds that did not get any allantoin administration.


In research studies on human subjects, a recovery of 19% and 34% of allantoin in the urine was observed but only in two individuals and only after the administration of massive dosages of allantoin. After intravenous administration, healing in the urine was practically quantitative with dosages of 75 to 600 mgm in the human design. After 240 mgm, excretion continued for 72 hours in human topics and the outcomes were comparable in regards to subcutaneous injection. [4]


Allantoin exists in botanical extracts of the comfrey plant and in the urine of the majority of mammals. Chemically manufactured bulk allantoin, which is chemically comparable to natural allantoin, is safe, non-toxic, compatible with cosmetic raw materials and fulfills ctfa and jsci requirements.

An animal research study in 2010 found that based on the results from histological analyses, a soft cream with 5% allantoin ameliorates the injury recovery procedure, by modulating the inflammatory reaction. The study also suggests that quantitative analysis lends support to the concept that allantoin also promotes fibroblast expansion and synthesis of the extracellular matrix.

A study published in 2009 reported the treatment of pruritus in mild-to-moderate atopic dermatitis with a topical nonsteroidal agent consisting of allantoin.


It is often present in toothpaste, mouthwash, and other oral health products, in hair shampoos, lipsticks, anti-acne products, sun care items, and clarifying lotions, numerous cosmetic lotions and creams, and other cosmetic and pharmaceutical products.

This medication is used as a moisturizer to deal with or prevent dry, rough, scaly, scratchy skin and small skin inflammations (such as diaper rash, skin burns from radiation treatment). Emollients are substances that soften and hydrate the skin and decrease itching and flaking. Some products (such as zinc oxide, white petrolatum) are utilized mostly to secure the skin against inflammation (such as from moisture). Dry skin is triggered by a loss of water in the upper layer of the skin. Emollients/moisturizers work by forming an oily layer on the top of the skin that traps water in the skin. Petrolatum, lanolin, mineral oil and dimethicone are common emollients. Humectants, consisting of glycerin, lecithin, and propylene glycol, draw water into the outer layer of skin. Many products also have ingredients that soften the horny substance (keratin) that holds the top layer of skin cells together (including urea, alpha hydroxy acids such as lactic/citric/glycolic acid, and allantoin). This assists the dead skin cells fall off, helps the skin keep in more water, and leaves the skin feeling smoother and softer.
