Brief Answer:
A few more details required...

Detailed Answer:
Hi,

I understand your concern.

I went through the photos you sent in and noted the purple mark.

I need to have a few more details before running into final conclusions:
- since when did you noticed that mark?
- any special activity you did?
- weather conditions: cold at the place you live?
- exposure to chemicals? new detergents?

From what I've seen, I can say that it is related to exposure of the hands to chemicals or cold weather.

Please provide the requested information to help you further.

Thank you.

Brief Answer:
It's skin reaction to cold weather explained below...

Detailed Answer:
Hi back,

Special activity means outdoor activities that require energy?

So far, from what you are saying, it seems a reaction to cold weather. I believe you are Asian native, not accustomed to cold, explaining this reaction of your skin.

Actually, these last few weeks were very cold and very low temperature outside.

To me, there is no need for anything. Just keep warm. It will last as long as the cold weather will last. When temperature will get higher, you won't have them anymore.

Hope this answers your questions.
All the best.

Brief Answer:
It is nothing worrisome...

Detailed Answer:
Hi back,

So far, don't look like blood disorder more than a local skin change to environmental conditions.

However, watchful waiting strategy recommended. If it doesn't go away or other unusual symptoms will appear, I recommend to run a few lab tests like:
- complete blood count
- blood iron levels
- liver/kidney function test
- Doppler ultrasound of the blood vessels on the arms.

All the best.
