What is CoQ10 in skincare?
Coenzyme Q10, also called ubiquinone, is a fat-soluble compound found in the mitochondria of every cell. It has two jobs: it carries electrons in the process that generates cellular energy, and it acts as an antioxidant protecting cell membranes from oxidation.
Skin levels of CoQ10 fall steadily with age and are further depleted by UV exposure, which is the rationale for replacing it topically.
What skin concerns does CoQ10 treat?
It targets the energy side of skin ageing – tired, dull, thinning skin with reduced cell activity – alongside fine lines and loss of firmness.
Topical application has been shown to raise CoQ10 levels in the skin and increase its antioxidant capacity, and laboratory work links it to reduced UVB-induced wrinkle formation. It is well tolerated, including on sensitive skin.
What ingredients are best paired with CoQ10?
Stack it with other antioxidants for a wider defence: vitamin C, vitamin E, ferulic acid, resveratrol and green tea all cover different free-radical species.
It pairs safely with retinoids, peptides, niacinamide and hyaluronic acid, making it easy to slot into an existing anti-ageing routine. As with all antioxidants, it supports sunscreen rather than substituting for it. Take our Skin Quiz.
What is pigmentation?
Pigmentation refers to any change in the colour of the skin caused by melanin. Hyperpigmentation – the common form – means patches darker than your natural tone, including sun spots, melasma, freckles and the marks left behind after acne or injury.
Melanin is produced by melanocytes in the lower epidermis and handed to surrounding skin cells. When that process is over-stimulated or unevenly distributed, the result is a visible patch rather than an even tone.
What causes pigmentation?
Ultraviolet exposure is the single largest trigger, because UV directly activates melanin production as a protective response. Inflammation is the second: acne, eczema, friction, waxing, burns or harsh procedures can all leave post-inflammatory hyperpigmentation, which is more common and longer-lasting in deeper skin tones.
Hormonal change, certain medications, heat and genetics complete the picture. Without daily sun protection, treated pigment reliably returns.
What ingredients are best for pigmentation?
The most effective topicals work at different points of melanin production: vitamin C and niacinamide, azelaic acid, tranexamic acid, alpha arbutin, kojic acid and liquorice root extract.
Retinoids and gentle AHAs speed up turnover so pigmented cells clear faster. But broad-spectrum SPF worn daily is the ingredient that decides whether any of it holds – without it, results reverse within weeks. Take our Skin Quiz.
