Lo que no comprendo es como este producto varia de precio en esta página... Yo lo compré en 10$ ahora va por 17$ y por 17$ no vale la pena. ¿Por qué? Porque si bien es algo innovador y original, es lo mismo que cualquier otra espuma limpiadora coreana... va bien. Entonces no veo porque pagar más

I'd say this is a good cleanser.  It cleans well and I do believe it's been helping to brighten my skin.  I've seen on other reviews that some people have said this cleanser makes their skin feel tight or itchy, and my skin does feel that way every so slightly after using it, but my skin always reacts that way to "foam" type cleansers.  I just apply my toner immediately after cleansing and it's fine.  I would love to try the green tea cleanser in this line to compare because my skin usually loves green tea products.
