Valuable / MOISTURISING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SOOTHING

Jojoba Esters are biomimetic ingredients that closely resemble the skin's natural sebum, offering exceptional hydration and robust barrier support. They contribute to a balanced, deeply moisturized complexion without a greasy residue, enhancing overall skin health and resilience.

Summary

Emollient Skin-softening Hydration Barrier Support Sebum Regulation Anti-inflammatory Antioxidant

Science

Mechanism of Action

Jojoba esters function by mimicking the natural lipids found in the skin's sebum, which strengthens the skin barrier and provides deep, long-lasting hydration. Their rapid absorption helps to lock in moisture effectively, preventing transepidermal water loss. These esters also possess anti-inflammatory and antioxidant properties, calming irritation and combating free radical damage. Furthermore, they signal the skin to regulate its own sebum production, promoting a balanced complexion, improved firmness, and elasticity.

Key findings

  1. 01 Commonly utilized at 1-5% in moisturizers for their hydrating and nourishing benefits.
  2. 02 A 2% concentration demonstrated significant improvement in transepidermal water loss (TEWL) within 30 minutes post-SLS irritation, maintaining effectiveness for at least 2 hours, and effectively reducing erythema for up to 24 hours.
  3. 03 A 3% concentration was overwhelmingly preferred by panelists across all sensory parameters in a study.
  4. 04 Higher concentrations (10-20%) are specifically employed in formulations like lip balms for intense moisturizing and nourishing effects.
  5. 05 Hydrolyzed Jojoba Esters (>=5%) have been shown to potentiate the moisturizing effect of glycerin in astringent and lotion formulations.
