Dark marks, brown spots & more: hyperpigmentation demystified.
Brown spots have a major influence on how old people think we are. In fact, one study showed that unbalanced skin tone can make a person look more than 12 years older! The big questions: where do they come from, and what can you do about them?
It helps to understand the science behind brown spots. The official term for brown spots and other forms of skin discolouration is hyperpigmentation. Unlike freckles, hyperpigmentation doesn’t fade in winter and, unfortunately, it becomes more visible as we age.
How is uneven skin tone caused?
Sun exposure: When your skin is repeatedly exposed to UV light, sun damage occurs. Brown spots and uneven skin tone develop as a result of too much melanin being produced to help protect your skin from UV light.
Pollution: Melasma is hormone-related hyperpigmentation caused by increased hormone stimulation. It’s most commonly experienced by women who are pregnant (which is why it’s also known as the “mask of pregnancy”) or taking contraceptives but can also be a reaction to cosmetics or medications.
Hormones: Skin is affected negatively by elevated stress hormones and many inflammatory conditions like eczema, psoriasis and acne can flare up during periods of stress.
Post-Inflammatory Hyperpigmentation: This type of dark spot is the result of inflammation or injury to the skin (for example, from acne, deep cuts or burns). Susceptibility to PIH typically increases with age, as cell turnover slows with age, and it takes dark spots longer to move to skin’s surface and slough off.
Still not sure what type of hyperpigmentation you have?

So, what to do about it? Here’s how to take action against your brown spots.

Apply SPF daily
Unprotected sun exposure is the number one culprit behind hyperpigmentation. Applying a sunscreen or moisturiser with a Broad-Spectrum SPF of at least 30, is the easiest way to help prevent new dark spots and it also helps control the colour intensity of the spots you can see. Wear it daily to make the most of the treatments you try. 30 minutes unprotected in the sun can undo a month’s worth of effort in fighting hyperpigmentation Tip: Try our PowerBright Moisturiser SPF50 for protection and treatment of pigmentation.
Exfoliate regularly
Exfoliation is the perfect way to treat existing hyperpigmentation by first sloughing off dead, dulling skin cells at the surface. This clears the path for the ingredients in your serums and moisturizers to better penetrate the skin. Tip: Look for a gentle, micro-fine exfoliant you can use daily, like Daily Microfoliant.
