What is jojoba oil in skincare?
Jojoba oil is pressed from the seeds of the Simmondsia chinensis shrub, native to the deserts of the American southwest. Technically it is not an oil at all but a liquid wax ester – and that distinction is the whole point.
Human sebum is roughly a quarter wax esters, so jojoba’s structure is unusually close to what skin produces naturally. That is why it absorbs cleanly and rarely feels greasy. It is also exceptionally stable and resists going rancid.
What skin concerns does jojoba oil treat?
It suits almost every skin type. On dry skin it softens and seals; on oily skin its similarity to sebum can help signal that less oil is needed; and it is non-comedogenic enough for acne-prone skin to tolerate.
It has documented anti-inflammatory activity, useful for eczema, psoriasis and general irritation, and laboratory work on human skin shows topical jojoba wax increases pro-collagen III and hyaluronic acid synthesis while lowering inflammatory markers.
What ingredients are best paired with jojoba oil?
Use it as the sealing step over humectants such as hyaluronic acid and glycerin, and alongside ceramides and squalane for barrier repair.
It also works as a carrier for essential oils and as a buffer for retinoids, taking the edge off dryness without blocking absorption. It is one of the few plant oils that dissolves hardened sebum, so it doubles as a gentle first-step cleansing oil. Take our Skin Quiz.
What is bumpy skin?
Bumpy skin is a texture problem rather than a single condition. It covers the rough, uneven surface you can feel more than see – most often keratosis pilaris (small hard bumps on the upper arms, thighs and cheeks), closed comedones, milia, or simple build-up of dead cells on the surface.
Keratosis pilaris in particular affects a large share of the population and is harmless, but it makes skin feel like sandpaper and can be stubborn to smooth out.
What causes bumpy skin?
Most bumpy texture comes from keratin plugging the follicle. When dead cells fail to shed cleanly, they collect at the pore opening and form a firm bump – a process closely linked to a weakened permeability barrier and low skin hydration.
Genetics, dry skin, cold weather, eczema and a history of over-scrubbing all make it worse. Aggressive physical exfoliation tends to backfire, inflaming the follicle and thickening the plug.
What ingredients are best for bumpy skin?
Chemical exfoliation works far better than scrubbing. Salicylic acid clears inside the follicle, lactic and glycolic acid loosen surface build-up, and urea both exfoliates and hydrates.
Retinoids normalise how skin sheds over time, while ceramides, niacinamide and hyaluronic acid keep the barrier strong so the plugs stop reforming. Consistency matters more than strength here. Take our Skin Quiz to work out which exfoliant your skin can tolerate.
