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

Clean enough to layer under SPF without turning soapy

The scalp gets clean

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

It's sweeter than the flanker name suggests

Neither overstates itself

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.
