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 adult acne?
Adult acne is acne that persists past the teenage years or appears for the first time in your twenties, thirties or later. It affects a substantial share of adults, and disproportionately women.
It tends to look different from teenage acne: fewer widespread blackheads, more deep tender lesions along the jawline, chin and neck, often on skin that is simultaneously dry, sensitive or already showing early signs of ageing.
What causes adult acne?
Hormonal fluctuation is the leading driver – menstrual cycles, coming off or starting contraception, pregnancy, perimenopause and conditions such as PCOS all shift androgen activity and sebum output.
Stress and cortisol, sleep debt, high-glycaemic diets, comedogenic makeup and skincare, friction, and certain medications compound it. Adult skin also heals more slowly, so marks linger longer than they did at nineteen.
What ingredients are best for adult acne?
The challenge is treating acne without wrecking a barrier that is also ageing. Retinoids do double duty here, clearing follicles and stimulating collagen at the same time.
Azelaic acid is excellent for adult skin because it handles lesions, redness and post-acne marks together. Add salicylic acid used sparingly, niacinamide to regulate oil and calm inflammation, and ceramides plus hyaluronic acid to keep hydration up. Skip harsh benzoyl peroxide concentrations and scrubs.
