Squalene Antioxidant Properties Fight Premature Skin Aging
01
Product Description
Squalene is a naturally occurring lipophilic triterpene hydrocarbon with the chemical formula C30H50. It is an essential component of human sebum, accounting for approximately 10–15% of the lipid content in healthy skin. Endogenously, squalene is synthesized in the liver and secreted through sebaceous glands to form a protective barrier on the skin surface.
Cosmetically used squalene is primarily derived from three sources:
Shark liver oil: The traditional source, where squalene constitutes up to 90% of the oil (extracted from deep-sea sharks such as the dogfish shark). However, this source has faced ethical and environmental controversies due to overfishing.
Plant-based sources: A sustainable alternative, extracted from olive oil, amaranth seeds, rice bran, and wheat germ. Plant-derived squalene has identical chemical properties to animal-sourced squalene and is widely adopted in modern cosmetic formulations.
Synthetic squalene: Produced via microbial fermentation (e.g., using yeast strains like Candida utilis) or chemical synthesis, offering a cruelty-free and scalable option for high-volume production.
In cosmetic formulations, squalene is a clear, odorless, and non-greasy liquid with excellent spreadability. It is compatible with most cosmetic ingredients, including oils, emollients, surfactants, and active compounds, and is stable under typical storage conditions (avoiding prolonged exposure to high temperatures and UV light).
Strengthens the skin barrier function
As a structural analog of human sebum, squalene integrates seamlessly into the skin’s lipid bilayer, replenishing depleted lipids in dry or damaged skin.
Potent antioxidant activity
Squalene scavenges free radicals generated by UV radiation, pollution, and oxidative stress, which are major causes of premature skin aging.
Anti-inflammatory and soothing effects
For sensitive, irritated, or post-procedure skin, squalene modulates the production of pro-inflammatory cytokines.
Enhances penetration of active ingredients
Its lipophilic nature allows squalene to act as a penetration enhancer, facilitating the delivery of oil-soluble active ingredients into the deeper layers of the epidermis. This synergistic effect boosts the efficacy of cosmetic actives without causing skin irritation.
01
Use
In cosmetic formulations, squalene is typically incorporated at a concentration of 0.5–10%, depending on the product type and desired function.

Facial care products
Moisturizers and creams, serums and essences, facial cleansers, sensitive skin care.
01
Body care products
Body lotions and oils: Added to body moisturizers to relieve dry, rough skin on elbows, knees, and heels; used in body oils for a non-greasy, glowing finish. Baby care products: Included in baby lotions and ointments because of its gentleness and ability to protect the delicate skin barrier of infants.
03
Sunscreen products
Added to mineral and chemical sunscreens to improve spreadability and reduce the white cast of mineral sunscreens (e.g., zinc oxide, titanium dioxide). It also enhances UV protection by scavenging free radicals generated by UV exposure, complementing the sunscreen’s function.
03
Hair care products
Hair serums and conditioners: Applied to dry or damaged hair to reduce frizz, improve manageability, and protect hair from heat styling damage. It coats the hair cuticle without weighing it down, enhancing shine and softness. Scalp care products: Used in scalp serums to soothe dry, itchy scalps and support a healthy scalp environment.
Storage
Store in a closed container at a dry place at room temperature.
