Kiehl's Clearly Corrective Dark Spot Solution 100ml Isntree Clean enough to layer under

Clean enough to layer under SPF without turning soapy

Neither overstates itself

Tuberose and almond — the opening is sweet-floral and unapologetic

Seaspray and cotton — the two notes that do exactly what their names say

The scalp gets clean

Kiehl's Clearly Corrective Dark Spot Solution 100ml Isntree Clean enough to layer underSalicylic acid and vitamin C working together the acid clears the pore while the vitamin C stops the spot from darkening in the first place. It's a serum, not a treatment mask, so it sinks in fast and layers under everything else. One or two pumps morning and night on clean skin, before moisturiser. Skip if you're using a retinol the same night; alternate them instead. The 100ml bottle lasts months at that dose.
