What is clay in skincare?
Clay in skincare means fine-grained mineral powders formed from weathered rock – kaolin, bentonite, montmorillonite, French green clay, rhassoul and fuller’s earth are the common ones. Each has a different mineral content and a different appetite for oil.
They work through adsorption and ion exchange: the charged mineral platelets bind sebum, dirt and bacteria on the skin surface. Reviews of clay minerals in dermocosmetics cover their absorbent, cleansing and mildly antibacterial properties.
What skin concerns does clay treat?
Clay masks suit oily, combination and congested skin. A clinical assessment of a clay mask in oily and acne-prone skin found measurable reductions in sebum and improvements in the look of pores.
They also help body breakouts and scalp oiliness. The limitation is duration: the effect is temporary, and over-use dehydrates the skin, which prompts it to produce more oil. Once or twice a week is the sensible ceiling.
What ingredients are best paired with clay?
Match the clay to the skin: kaolin is the mildest and suits sensitive or drier skin, bentonite and fuller’s earth are the most absorbent and suit oily skin.
Blend or follow with soothing, hydrating ingredients – glycerin, hyaluronic acid, aloe, colloidal oatmeal, niacinamide. Rinse the mask before it cracks; a fully dried clay mask pulls moisture out of the skin as well as oil. 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.
