Jojoba Oil

Jojoba “oil” is actually a liquid wax pressed from the seeds of Simmondsia chinensis. It’s composed of ~97–98% wax esters (very little free fatty acids), a structure that closely resembles human sebum and underpins its excellent skin feel and stability.PMC+1

1) Sebum-mimicking, lightweight emollience

Because its long-chain wax esters are similar to those in natural sebum, jojoba spreads easily, softens the stratum corneum, and supports barrier lipids without a heavy, greasy film. Reviews and topical plant-oil overviews list jojoba as an effective emollient for barrier support.PMC+1

2) Calms inflammation

In experimental models, jojoba liquid wax lowered inflammatory markers and edema (e.g., reduced TNF-α, PGE₂, neutrophil infiltration). More recently, human skin explant work showed topical jojoba wax reduced IL-6, IL-8, and TNF-α by ~30% after LPS challenge. Together these point to a gently anti-inflammatory profile.PubMedIJECFrontiers

3) Supports wound-repair processes

In vitro scratch-wound studies on keratinocytes and fibroblasts found jojoba liquid wax accelerated wound closure via PI3K-Akt-mTOR and MAPK signaling and stimulated collagen I synthesis—useful mechanistic support for barrier care.PubMedScienceDirectPortal de Periódicos da CAPES

4) May help acne-prone skin (mild cases)

A prospective study using a clay + jojoba oil mask in mild acne reported improvement in lesions and quality-of-life scores (pilot data). It’s not a medicine, but it supports jojoba’s non-heavy, soothing role in routines.PubMedZurich Open Repository and Archive

• Cosmetic safety: The Cosmetic Ingredient Review (CIR) concludes jojoba oil/derivatives are safe as used; human testing found products with jojoba non-phototoxic and non-photoallergic.CIR ReportsCIR Safety
  
• Infant use context: Jojoba appears widely tolerated in baby products, but direct neonatal RCT evidence is limited; general baby-skincare studies show “natural regimens” can be well tolerated, while some oils (e.g., olive) may disrupt barrier in certain settings. For newborns, keep use simple, patch-test, and follow clinician advice for eczema.PMC+1
  

Allergy note: True allergy is uncommon; as with any leave-on, patch-test first on very reactive skin.

In Natural Nine, Simmondsia Chinensis Seed Oil delivers the silky slip and fast-absorbing comfort you feel on application. Its sebum-like wax esters soften and support the barrier, while our beeswax (Cera Alba) adds a breathable shield and shea butter cushions dryness—keeping the blend gentle enough for delicate, sensitive skin.
