What is coconut oil in skincare?
Coconut oil is extracted from the dried flesh of the coconut. It is unusual among plant oils in being mostly saturated fat – around half of it is lauric acid, a medium-chain fatty acid with strong antimicrobial activity.
Virgin coconut oil retains more of its polyphenols than refined. It is solid at room temperature, melts on contact with skin, and is highly occlusive, which is both its main strength and its main problem.
What skin concerns does coconut oil treat?
On dry body skin, hands, feet and cuticles it is an effective occlusive that reduces water loss, and research on plant oils credits it with anti-inflammatory and antibacterial effects, including activity relevant to atopic dermatitis.
On the face it is a different story: coconut oil rates high on the comedogenic scale and reliably causes congestion and breakouts in oily and acne-prone skin. Its lauric acid does inhibit acne bacteria, but the pore-clogging usually outweighs that.
What ingredients are best paired with coconut oil?
Treat it as a body occlusive. Apply it over a humectant such as glycerin or hyaluronic acid on damp skin, or over a ceramide lotion, so it seals rather than sits.
For the face, choose non-comedogenic alternatives: squalane, jojoba, rosehip or grapeseed oil give emollience without the congestion. It is also a good pre-shampoo hair treatment. Take our Skin Quiz.
What are age spots?
Age spots – known clinically as solar lentigines, and sometimes as liver spots – are flat, well-defined brown or tan patches that appear on skin with the most cumulative sun exposure: the face, backs of the hands, forearms, shoulders and upper chest.
Despite the name, they are not caused by age itself. They are a record of ultraviolet exposure, which is why they are common from the forties onward and why they cluster on areas that rarely get sunscreen.
What causes age spots?
Long-term UV exposure drives melanocytes to over-produce melanin in concentrated spots, and the surrounding keratinocytes stop clearing that pigment efficiently as skin ages.
Fair skin, a history of sunburns, tanning beds and outdoor work all raise the risk. Any new spot that changes shape, colour or size, bleeds or has an irregular border should be checked by a doctor rather than treated cosmetically.
What ingredients are best for age spots?
Topical treatment works but needs patience – expect three to six months. Retinoids speed turnover so pigmented cells shed faster, vitamin C and niacinamide brighten and protect, and alpha arbutin, kojic acid, azelaic acid and liquorice root inhibit new pigment.
Glycolic or lactic acid helps lift existing pigment from the surface. Daily broad-spectrum SPF, including on hands and chest, is what prevents new spots forming. Take our Skin Quiz.
