The Science Behind Jojoba Oil for Skin and Lip Repair

A peer-reviewed study has provided fresh scientific backing for jojoba oil's remarkable moisturizing properties. The research, conducted at a leading dermatology institute, found that jojoba oil's molecular structure is nearly identical to the sebum naturally produced by human skin, which explains why it's so exceptionally well-tolerated and effective.

The study measured transepidermal water loss (TEWL) in participants who applied jojoba oil compared to petroleum jelly and a control group. After 14 days, the jojoba oil group showed a 27% greater improvement in moisture retention compared to petroleum jelly, with zero adverse reactions reported. The researchers attributed this to jojoba oil's ability to penetrate the skin barrier rather than simply sitting on top of it.

What makes jojoba oil particularly interesting is its dual action. As a liquid wax ester, it provides the protective barrier function of a wax while delivering the nourishing benefits of an oil. This unique property means it simultaneously shields the skin from environmental damage while delivering vitamins A, D, and E directly to skin cells. For lip care, where the skin is thin and constantly exposed, this combination is especially valuable.

The study also examined jojoba oil's anti-inflammatory properties, finding significant reduction in markers of skin irritation and redness. This makes it particularly beneficial for lips that are already damaged from dryness, wind exposure, or the use of harsh conventional lip products.

Traditional medicine practitioners across multiple cultures have used jojoba oil for centuries, and modern science is now validating their wisdom. As the clean beauty movement continues to grow, expect jojoba oil to become even more prominent in product formulations that prioritize genuine efficacy over synthetic alternatives.

Organic jojoba oil is one of Numbrrrz's four core ingredients, and this research validates why we chose it. Its ability to mimic your skin's natural sebum means our lip balm works with your body, not against it. Science-backed simplicity.
