Phosphatidylcholine

Phosphatidylcholine — the main phospholipid of cell membranes and a natural component of the skin barrier. It restores the lipid structure of the epidermis, increases the permeability of active ingredients, and is a key building material for liposomal delivery systems.

What is it?

Phosphatidylcholine (INCI: Lecithin, Phosphatidylcholine) — glycerophospholipid: diacylglycerol + phosphocholine head group. Composition: glycerin + two fatty acids (C16-C18, mainly linoleic and oleic) + phosphocholine. MW: ~760 Da. Amphiphilic molecule: hydrophilic phosphocholine head + hydrophobic fatty acid tails → self-organization into liposomes/bilayers. Main source: sunflower lecithin (non-GMO risk) or soy lecithin. Mechanism on skin: incorporation into the lipid barrier SC → restoration of damaged lamellar structure → reduction of TEWL.

Liposomal serums and delivery agents, restorative agents for dry and damaged skin, anti-aging systems, products for sensitive skin, creams with an emulsifying system.

Key Benefits

✦

Restoration of the lipid barrier — integration into SC

Phosphatidylcholine is a structural analog of skin barrier lipids (along with ceramides and cholesterol). Upon application: phospholipid molecules integrate into lamellar structures between corneocytes → filling barrier defects. Result: restoration of TEWL indicators, improved hydration, reduced sensitivity. Especially effective for: atopic dermatitis, dry and dehydrated skin, post-procedure recovery (laser, peels). In vivo data: significant reduction of TEWL after 4 weeks of using a 5% PC cream in xerosis.

◈

Delivery system — liposomes and nanoemulsions

Phosphatidylcholine is a leading building material for liposomes — closed vesicles with an aqueous core surrounded by a phospholipid bilayer. Liposomes: protect actives from degradation (vitamin C, retinol, peptides); penetrate through the stratum corneum; controlled release. Nanoemulsions: size 20-200 nm → better penetration vs regular emulsions. Commercial systems: liposomal vitamin C (10-20% ascorbic acid in liposomes — stable and penetrative form). Advantages of PC liposomes: biocompatible, non-toxic, biodegradable.

✧

Moisturization and softening — emollient and humectant

Phosphatidylcholine combines the properties of an emollient and a moisturizer. Emollient: filling intercellular spaces in SC → feeling of softness and silkiness. Moisturization: the phosphocholine group is hydrophilic → moisture retention. Lecithin's function as an emulsifier: HLB ~8-10 → stabilization of o/w and w/o emulsions; a natural alternative to synthetic surfactants in clean formulas. Result: feeling of comfort, reduced tightness and flaking. Effective for: dry, mature, sensitive skin, skin with a compromised barrier.

Phosphatidylcholine: lecithin and soy allergy

Phosphatidylcholine = active component of lecithin. INCI: Lecithin (general) or Phosphatidylcholine (purified). Sources: sunflower lecithin (Helianthus annuus) — soy-free, safe. Soy lecithin: potential allergen for individuals with soy allergy. Effective concentration: 1-5% in creams; 10-20% in liposomal systems. Stability: prone to oxidation of PUFA — store in a dark place, add tocopherol. pH-stable 4-8.
