Skin, Hair and Nail Problems

My son 4 months old is diagnosed with griscelli type 3 syndrome, his scalp hair has turned silver grey with hypopigmentation.. any treatment /hospitals to cure it .. please suggest

The fingers have dry area which is not disappearing, it has been 4 months the dry area is not recovering

Lot of dryness from past one week in hand / palm only. Refer attached image. Keeping my self hydrated and applying mosuturizer/ cold cream but no effect

I have tiny bumps from 1week after suddenly its itching & irritation & rashes then turn into blackness & now it's turn into dry skin flacky n pain full what is the reason & what is the solution???

Since last week whole body is itching and I am sweating too there are small red rashes , bumps in hands , arms ,back

Last 1 week I am getting these red colored small patches that are very ichy and disappear in few hours. But again new patches  appear. They are mostly on legs and very few hands. But today I am feeling itchy on my face but there are no patches on face. Could it be because of waxing? That was done 15 days back but I do have ingrown hair which is itchy. But these patches are also on areas I did not get waxed like thighs. Haven't taken any medicine.

How long does it take for a love bite to heal? What are the things I can do to Remove them as early as possible? Is arnica gel really effective?

Please suggest  gentle chemical exfoliation products for body as well as for facial skin. I have ingrown hair on my legs and arms. My overall skin type is dry and on the sensitive side.

Sir/mam I have the problem of early greying of hair in last 2 - 3 years and I am very depressed from this situation because I look older than my age due to this problem. If you have any solution regarding this please let me know

Hello Doctor, I have 2 months,20 days baby and I'm feeding him daily. Can I use vitamin c serum (Garnier) for face (these days my face became dull and unclear) . And can I use any undereye cream (mom's co or Himalaya) for darkness and carry bags. Can I use attached ones or please suggest other Products. Thank you.
