What is hemp seed oil in skincare?
Hemp seed oil is cold-pressed from the seeds of Cannabis sativa. It contains no meaningful CBD or THC – those come from the flowers and leaves – so it is a pure lipid ingredient rather than a cannabinoid one.
Its distinguishing feature is fatty acid balance: roughly 55% linoleic acid and 20% alpha-linolenic acid, close to the ideal ratio for skin. Linoleic acid is a direct precursor to the ceramides that hold the barrier together.
What skin concerns does hemp seed oil treat?
It is one of the better facial oils for oily and acne-prone skin, because linoleic-rich oils thin sebum rather than thicken it, and it rates as non-comedogenic.
Its anti-inflammatory profile makes it useful for eczema, dermatitis and general redness, and its lightweight hydration suits dehydrated skin that cannot tolerate heavy creams. It absorbs quickly and leaves a dry, non-greasy finish.
What ingredients are best paired with hemp seed oil?
Pair it with niacinamide for oil control, hyaluronic acid underneath for hydration, and ceramides alongside for barrier repair.
It buffers retinoids and acids well without blocking them. Like all high-linoleic oils it oxidises quickly, so keep it refrigerated and buy small bottles – rancid oil is pro-inflammatory, which defeats the purpose. Take our Skin Quiz.
What is rosacea?
Rosacea is a chronic inflammatory skin condition that affects the central face – cheeks, nose, chin and forehead. It presents as persistent redness, visible broken capillaries, flushing that comes and goes, and in some subtypes acne-like papules and pustules.
Unlike acne, rosacea involves no comedones. It is driven by a combination of vascular hyper-reactivity, neurogenic inflammation and an overactive innate immune response, often with an impaired skin barrier alongside.
What causes rosacea?
There is no single cause. Genetic predisposition, an exaggerated immune response involving cathelicidin, overgrowth of Demodex mites, and dysfunction of the facial blood vessels all appear to contribute.
Flares are triggered by heat, sun exposure, alcohol, spicy food, hot drinks, exercise, stress, wind and cold, and by harsh skincare. Identifying and avoiding your own trigger set does as much as any product.
What ingredients are best for rosacea?
Azelaic acid and niacinamide are the standout actives – both reduce redness and inflammation without provoking the barrier. Sulphur, green tea extract, liquorice root and centella asiatica also calm reactive skin.
Build everything else around barrier repair: ceramides, glycerin, squalane and panthenol, with a gentle non-foaming cleanser and a mineral SPF every day. Avoid alcohol-heavy toners, fragrance, menthol, physical scrubs and high-strength acids. Take our Skin Quiz to build a routine your skin will tolerate.
