What is resveratrol in skincare?
Resveratrol is a polyphenol produced by plants under stress – grapes, berries, peanuts and Japanese knotweed are the main sources. Red wine is where most people first hear of it, though the amounts there are trivial.
In skincare it functions as a potent antioxidant and an activator of sirtuins, proteins involved in cellular repair and longevity. It is well characterised for antioxidant, anti-inflammatory and antimicrobial activity on skin.
What skin concerns does resveratrol treat?
It targets the visible results of oxidative stress: dullness, uneven tone, fine lines and loss of firmness. Its anti-inflammatory action also helps redness and reactive skin.
It has documented skin-lightening activity through tyrosinase inhibition, making it a gentler option for pigmentation than many actives, and a small trial found it reduced facial redness when combined with green tea and caffeine.
What ingredients are best paired with resveratrol?
It is typically used at night, where it complements the repair work skin does while you sleep, and it pairs particularly well with vitamin E, ferulic acid, niacinamide and green tea.
It also combines safely with retinoids and peptides. Because it is unstable in light, look for opaque, air-tight packaging – a resveratrol serum in a clear dropper bottle is not doing much. Take our Skin Quiz.
What are dark spots?
Dark spots are localised patches where the skin has produced more melanin than the surrounding area. The umbrella term covers sun spots, post-acne marks, melasma patches and freckles – different causes, same visible result.
They are flat rather than raised, vary from light tan to deep brown, and are most noticeable on the face, hands and chest. In deeper skin tones they tend to be darker and to last considerably longer.
What causes dark spots?
Two mechanisms dominate. Ultraviolet exposure triggers protective melanin production, and inflammation – from acne, ingrown hairs, eczema, friction, burns or harsh treatments – leaves post-inflammatory hyperpigmentation behind as it heals.
Hormonal change, some medications and heat add to it. Picking at spots is one of the most avoidable causes: the extra inflammation reliably makes the mark darker and longer-lived than the original blemish.
What ingredients are best for dark spots?
Vitamin C, niacinamide and azelaic acid are the everyday workhorses. For stubborn pigment, alpha arbutin, tranexamic acid, kojic acid and liquorice root extract interrupt melanin production directly.
Retinoids and gentle AHAs clear pigmented cells faster from the surface. Give any routine twelve weeks before judging it, and wear broad-spectrum SPF daily or the spots will simply redarken. Take our Skin Quiz.
