Hi, I'm 29 years old female, weighting 73 kg. I'm facing the issue of knuddle pigmentation (darkness below the nails skin ) on both the hands since 6 months. For this, I have started taking fefol z, supradyn & Matilda forte tablets since one month upon consulting one doctor but There is very slight progress I can see. Please suggest if there is something else I can do to remove this skin darkness.
