Hi hun, Beauty advisor here - Clay masks help to absorb oil and clean the skin, it's perfect for oily skin. If you are already using Paula's choice liquid exfoliator I would not recommend using the clay mask as it will overly dry your skin, making your facial skin age faster. The best way to tackle whiteheads is with gentle exfoliation, you can also steam your face and use an extractor tool but be careful not to over use it or you can cause scarring! Good luck on your skincare journey! if you find this advice useful, please consider following me on Instagram @itsnickyie. I Follow back :)
