    "I really love this duo. Finally seeing good results after battling with acne for 6+ months and trying out dozens of producs. Definitely recommend for anyone who is fighting with acne and stubborn dark spots. Faded mine within weeks. Still have a few spots, but still a HUGE difference. These photos were taken a month apart."

    "Never leave reviews but this product has transformed my skin. Went from congested skin, cystic spots, trapped pores and whiteheads & redness to clear and smooth skin. My skin does not breakout anymore and redness is reduced a lot! I have attached photos that I have used for tracking - 2 month difference. Been using this alongside the salicylic acid cleanser."
