Mechanism of Action
Allantoin
Allantoin (5-ureidohydantoin) stimulates cell proliferation and tissue regeneration by promoting fibroblast activity, keratinocyte proliferation, and extracellular matrix synthesis including collagen and glycosaminoglycans. It acts as a mild keratolytic by promoting the natural desquamation process—loosening corneocyte adhesion and facilitating shedding—without the irritation, pH disruption, or barrier compromise associated with alpha- or beta-hydroxy acids. Allantoin has anti-inflammatory properties through modulation of prostaglandin synthesis (inhibiting COX-2 and reducing PGE2) and may downregulate pro-inflammatory cytokines. Its moisturizing effect comes from increasing the water-binding capacity of the extracellular matrix and stratum corneum; it is highly soluble and forms hydrogen bonds with water. Allantoin also promotes wound epithelialization. Its safety profile—non-irritating, non-sensitizing, non-comedogenic—makes it suitable for compromised skin, post-procedure care, and infant formulations.
Jojoba Oil
Jojoba wax esters (C36-C46) are structurally similar to wax esters comprising 25-30% of human sebum — both formed from long-chain fatty acids esterified to long-chain fatty alcohols (unlike triglycerides in true oils). Integrates into skin's lipid layer and lamellar structure without barrier disruption or comedogenesis. Occlusive moisture retention; sebum-mimetic composition may signal sebaceous glands via feedback to moderate production — effective for dry skin (adds moisture) and oily skin (reduces overproduction). Contains myristic acid (anti-inflammatory), vitamin E (antioxidant), mild antibacterial activity. Wax ester structure extremely stable, oxidation-resistant. Liquid wax from Simmondsia chinensis seeds. Non-comedogenic. May normalize sebum composition in acne-prone skin.
Risks & Safety
Allantoin
Common
None. Allantoin is non-irritating, non-sensitizing, and non-comedogenic.
Serious
None.
Rare
Allergic reaction is extremely rare.
Jojoba Oil
Common
Very well-tolerated. Rarely causes breakouts due to sebum-mimicking composition.
Serious
None.
Rare
Very rare allergic reaction.
Full Profiles
Allantoin →
A gentle compound found naturally in comfrey root, chamomile, and wheat sprouts that promotes skin healing, moisturization, and the shedding of dead skin cells. Allantoin has been used in dermatology for over 70 years and is one of the most universally tolerated ingredients — it soothes, protects, and promotes recovery without any known irritation potential. Found in everything from diaper cream to post-procedure products.
Jojoba Oil →
Technically a liquid wax ester (not a true oil) derived from Simmondsia chinensis seeds. Jojoba oil has a composition remarkably similar to human sebum — approximately 97% wax esters, which closely mimic the skin's natural oils. This makes it one of the most skin-compatible oils available. It provides emollient moisture, regulates sebum production, and has anti-inflammatory properties. Suitable for all skin types including oily and acne-prone.
