What is rosehip oil in skincare?
Rosehip oil is cold-pressed from the seeds and fruit of Rosa canina or Rosa rubiginosa – the hip left behind after a rose has flowered. It should not be confused with rose oil, which is distilled from petals and is a fragrance ingredient.
It is rich in linoleic and linolenic acid, vitamin E, and naturally occurring trans-retinoic acid in trace amounts. It has a light, dry feel and a faint earthy scent, and reviews of rosehip-based dermatological products document antioxidant, anti-inflammatory and regenerative activity.
What skin concerns does rosehip oil treat?
It suits dry, dehydrated and mature skin, and its essential fatty acids help calm eczema and general irritation. The vitamin A compounds give it a mild resurfacing effect on tone and texture without retinoid-level irritation.
Its best-documented use is repair: experimental work shows rosehip oil promotes excisional wound healing, which underpins its popularity for scars, stretch marks and post-acne marks.
What ingredients are best paired with rosehip oil?
Layer it over hyaluronic acid or a hydrating serum, and alongside ceramides and squalane for a complete barrier routine. It pairs well with vitamin C for brightening.
Because it already contains vitamin A compounds, introduce it slowly if you are also using a retinoid. Its high linoleic content makes it a better choice for oily skin than most oils, but it oxidises quickly – buy small, opaque bottles and refrigerate. 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.
