Valuable CAS 90082-87-4 / SKIN CONDITIONING

Prunus Domestica Seed Oil is a multifaceted botanical oil rich in essential fatty acids and potent antioxidants. It deeply moisturizes and reinforces the skin's barrier, effectively reducing transepidermal water loss and enhancing skin hydration. Its robust antioxidant profile provides comprehensive protection against oxidative stress, contributing to improved skin elasticity, tone, and a reduction in visible signs of aging.

Emollient Antioxidant Skin-conditioning Soothing Nourishing Moisturizing Anti-aging Softening Lipid-replenishing Redensifying

Science

Mechanism of Action

PRUNUS DOMESTICA SEED OIL delivers its benefits through a rich composition of fatty acids, predominantly oleic acid (~70%) and linoleic acid (~20%), alongside a complex of antioxidants including Vitamin E, polyphenols, provitamin A (beta-carotene), Vitamin C, and squalene, further complemented by phytosterols. These components synergistically hydrate and fortify the skin's natural lipid barrier, significantly reducing moisture loss. The high antioxidant content actively neutralizes free radicals, mitigating oxidative stress and preventing premature aging, while also supporting collagen production and improving skin elasticity. Additionally, it calms irritation, alleviates redness and dryness, promotes gentle cellular renewal for a brighter complexion, and assists in balancing sebum production.

Key findings

  1. 01 An in vivo study demonstrated that a 6% (w/w) concentration of plum seed oil, incorporated into an emulgel and applied over a 28-day period, significantly increased skin hydration and decreased transepidermal water loss (TEWL). This study also confirmed the oil's lack of irritation potential and its ability to preserve skin pH, integrity, and color.
  2. 02 A 2020 study published in the Journal of Cosmetic Dermatology indicated that fruit seed oils, including plum, exhibit high antioxidant activity, effectively reducing lipid peroxidation and contributing to improved skin elasticity over time.
