Data & Research

Scientific Facts

Allanotin, a precursor to allantoin, is naturally found in the urine of mammals (excluding humans and higher apes), serving as a primary method for excreting nitrogen-containing waste. Allantoin is also present in various plants, including comfrey, horse chestnut, and bearberry. Commercially produced allantoin for cosmetic use is typically synthesized from urea and glyoxylic acid.

Common Uses

Formulation in Allantoin

Allantoin, along with its derivatives (allantoin ascorbate, allantoin biotin, allantoin galacturonic acid, allantoin polygalacturonic acid, allantoin glycyrrhetinic acid and allantoin panthenol), are used as skin-conditioning agents. Allantoin also functions as a skin protectant.

Role of Allantoin

Active Cosmetic Mechanisms

SKIN CONDITIONING

Skin Enhancer

Maintains skin in good condition and improves its feel

SCIENTIFIC ANALYSIS

// Evidence: Skin conditioning ingredients enhance appearance, texture, and health of skin through various mechanisms. This broad category encompasses emollients, humectants, occlusives, and other agents that improve skin feel, appearance, and function. May work by moisturizing, smoothing, softening, or protecting skin. Effects include improved tactile properties, enhanced barrier function, and better overall skin condition.

SKIN PROTECTING

Defensive Shield

Shields skin from external aggressors and damage

SCIENTIFIC ANALYSIS

// Evidence: Skin protecting ingredients defend against environmental stressors, irritants, and damage through barrier enhancement, antioxidant activity, anti-pollution effects, or physical barriers. Include dimethicone (barrier), allantoin (soothing protectant), zinc oxide (physical protectant), and film-formers. Mechanisms vary: forming protective films, neutralizing oxidative stress, chelating pollutants, strengthening barrier function. Used in protective creams, barrier treatments, and defensive skincare against urban pollution, extreme weather.

SOOTHING

Calming Agent

Calms and comforts irritated or sensitive skin

SCIENTIFIC ANALYSIS

// Evidence: Soothing ingredients reduce discomfort, redness, and inflammation through anti-inflammatory mechanisms. Include allantoin (stimulates healing), bisabolol (anti-inflammatory), colloidal oatmeal (skin protectant), panthenol (hydrating, barrier repair), and botanical extracts (aloe, chamomile, calendula). Mechanisms involve inhibiting inflammatory mediators (prostaglandins, cytokines), reducing histamine release, strengthening barrier function, and providing cooling sensation. Essential for sensitive, reactive, or post-procedure skin.
