Dry, compromised skin can't exfoliate properly on its own, so dead pigmented cells build up rather than shedding – the fix is combining hydration, gentle exfoliation and a brightening active, which is why a rich moisturiser formulated with brightening ingredients is often the most efficient single product for this combo.

• Compromised skin barriers slow down natural cell turnover, meaning pigmented cells sit on the surface longer than they should.
• Adding hydration first helps restore normal turnover, which supports whatever brightening active you use.
• Gentle exfoliation (like mandelic acid) helps shed those built-up pigmented cells more efficiently.
• A rich, brightening moisturiser formulated for dry skin tackles both concerns in a single step.
• Give this combination approach consistent time before expecting visible change.

Go thin to thick and water-based to oil-based – brightening tonic first, then your active serum, then a rich moisturiser on top – and skip alcohol-based products entirely, adding squalane or a ceramide step first if your skin is very dry.

• Layer water-based products before oil-based ones so nothing blocks absorption of the next step.
• A brightening tonic first, then your treatment serum, then a rich moisturiser is the standard order.
• Skip alcohol-based toners or tonics completely – they're the fastest way to trigger tightness and flaking.
• If your skin is very dry, add squalane or a ceramide moisturiser before your final layer to lock everything in.
• Give your skin a minute or two between each layer so products actually absorb properly.
