I will share my Experience with you about Clean and clear blackhead clearing scrub.
It is used for exfoliating Skin to unclock the skin pores to remove dirt impurities from the skin ports which is caused by daily polluted environment but the adverse effects of general scrubs are open pores which give bumpy pores appearance.
This is because due to large size of scrub particles but using this product I did not face any problems. The advantage of the product is that it has micro scrub particles which does nt lead to the porous appearance of the skin. So I would recommend you to buy this product for blackhead cleaning.
