My skin around the corners of my nose and just below the lower lip appears to be unusually darker than the rest of my face. Also, I think there are lot of whitish bumps all over the above mentioned areas, along with flaky skin especially on the corners of my nose. (i have this constant urge to scrub them off. Is this okay) so, I have been applying eumosone m for about 4 months now (once everyday), but the problem is consistent. Should I use it twice or thrice? Or should I try anything else?
