I have the oiliest skin ever and i do have blocked pores, big pores, whiteheads blackheads and cystic acne so i started out with really bad skin. I got clocked a 2 on Ernolaszlo.com and this is my night treatment i use this after washing (splashing) with the oil control bar or the beta wash and toning with the conditioning treatment. This soothes my skin and keeps it matte all night. Since i dont wake up like an oil slick i wake up with fewer to no breakouts which i definately attribute to the Erno Laslo regimen and this night treatment. In winter when skin is a little drier i add just a tiny bit of the phelityl night cream over this. In todays skin care products with alcohol are rare because newer researches showed that alcohol can worsen the skin i think different the Laszlo treatments and toners are still much more soothing and less harsh than retinol, antibiotic acne treatments or acne treatments with tretinoin which i used before and theyre even more expensive in the long run since you need prescription and doctor visits. My skin as for now looks and feels much better and i hope i can stay cystic acne free. Great Product.
