What is cacay oil in skincare?
Cacay oil is pressed from the nuts of the cacay tree, which grows in the Amazon basin of Colombia and Peru. It is a relative newcomer to Western skincare and is marketed as a natural source of retinol.
Its composition is genuinely distinctive: a high proportion of linoleic acid, roughly three times the vitamin E of argan oil, and naturally occurring retinol at levels reported to be considerably higher than rosehip oil. Like other linoleic-rich plant oils it supports barrier repair rather than weighing skin down.
What skin concerns does cacay oil treat?
Its retinol content gives it a mild effect on fine lines, uneven tone and texture, without the irritation of a formulated retinoid – useful for people whose skin cannot tolerate one.
The linoleic acid suits dehydrated, combination and mildly acne-prone skin, and the vitamin E provides antioxidant protection. It absorbs quickly and does not leave a greasy film.
What ingredients are best paired with cacay oil?
Layer it over hyaluronic acid and alongside ceramides and niacinamide. It is a sensible bridge for someone easing towards retinoids.
Because it contains vitamin A compounds, use it at night and keep wearing SPF, and introduce it gradually if you already use a retinoid. Expect a gentle, cumulative effect rather than retinol-strength results. Take our Skin Quiz.
What is melasma?
Melasma is a common form of acquired hyperpigmentation that appears as symmetrical brown or greyish-brown patches, most often across the cheeks, forehead, upper lip and jawline. It develops when melanocytes – the pigment-producing cells in the skin – become overactive and deposit excess melanin into the epidermis, the dermis, or both.
It is far more common in women and in medium to deeper skin tones, and it behaves as a chronic, relapsing condition rather than a one-off mark – which is why management matters as much as treatment.
What causes melasma?
Three triggers dominate: ultraviolet and visible light exposure, hormonal change (pregnancy, oral contraceptives and hormone therapy – hence its nickname, the mask of pregnancy), and genetic predisposition.
Heat, visible light from sunlight and screens, inflammation from harsh products or aggressive procedures, and certain medications all make existing patches worse. Because the triggers are ongoing, melasma typically fades and returns rather than clearing permanently.
What ingredients are best for melasma?
Daily broad-spectrum sunscreen is non-negotiable, and a tinted mineral SPF containing iron oxides is best because it also screens the visible light that drives pigment production.
On top of that, the most evidence-backed actives are tranexamic acid, azelaic acid, niacinamide, vitamin C, alpha arbutin, kojic acid, liquorice root extract, retinoids and gentle alpha-hydroxy acids. Avoid harsh scrubs and strong heat, both of which can rebound the pigment. Take our Skin Quiz to build a routine around your skin tone and triggers.
