Squalane is a highly refined, saturated hydrocarbon derived from squalene, a natural substance found in the skin's sebum. Squalene itself is produced by human skin cells, but the quantity decreases with age. Squalane is the hydrogenated, more stable form of squalene, which makes it more suitable for use in skincare products.
Squalane is usually derived from plant sources such as olives, sugarcane, or amaranth seeds, though it was originally sourced from shark liver oil (a practice now largely discontinued due to ethical and sustainability concerns).
Functions
- Moisturization: Squalane is an excellent emollient, which means it helps to soften and smooth the skin. It mimics the skin’s natural oils, making it an effective moisturizer that helps to maintain skin hydration without feeling greasy.
- Skin Barrier Protection: Squalane reinforces the skin's barrier function, helping to protect it from environmental stressors such as pollutants and allergens. A strong skin barrier prevents moisture loss and keeps the skin resilient against damage.
- Antioxidant Properties: Squalane has antioxidant properties, which means it helps to fight free radicals that can cause premature aging. This can lead to reduced appearance of fine lines and wrinkles over time.
- Non-Comedogenic: Despite being an oil, squalane is non-comedogenic, meaning it doesn’t clog pores. This makes it suitable for all skin types, including those prone to acne.
- Anti-Inflammatory: Squalane has anti-inflammatory properties, which can help reduce redness and swelling, making it beneficial for sensitive or irritated skin.
- Enhances Skin Absorption: Squalane improves the absorption of other skincare ingredients, making it an excellent carrier oil for other active ingredients in a skincare routine.
Who is Suitable for Using Squalane?
- All Skin Types:
- Dry Skin: Squalane provides deep hydration without being heavy, making it ideal for dry skin.
- Oily Skin: Since it's non-comedogenic and lightweight, it doesn't cause breakouts or add excess oil.
- Combination Skin: Squalane balances oil production and moisturizes dry areas effectively.
- Sensitive Skin: Its anti-inflammatory properties and gentle nature make it suitable for sensitive skin, reducing redness and irritation.
- Aging Skin: Due to its antioxidant properties, squalane is beneficial for aging skin, helping to reduce the appearance of fine lines and wrinkles and improve skin elasticity.
- Acne-Prone Skin: Squalane’s non-comedogenic nature means it won’t clog pores, and its anti-inflammatory properties can help calm acne.
- Post-Treatment Skin: For those recovering from dermatological treatments like chemical peels, laser treatments, or retinoid use, squalane can soothe and moisturize the skin, aiding in the healing process.
