It may takes 4-6 weeks to achieve full result.
I read carefully your query and understand your concern.
Well 3 days after mole removal is too early to see the results.
It is normal that after the mole removal through cauterization
a scab will develop, and then heal within a week or two.You should keep a bandage over the area for a few days to keep infection out of the wound.
Do not irritate the scab and let it fall off naturally. Once the scab had flaked off (one to two weeks after the procedure), you can stop wearing a bandage over it and treat it like normal skin.
Also any redness
that occurs will disappear within two to four weeks.
The wounds will heal and you would achieve the full results by 4 – 6 weeks.
that do appear slowly fade over time ( one to three years).
You need to be patient and don't be discouraged so soon.It takes some time for the skin to recover completely.
Meanwhile you should care for the area by keeping it clean and free from bacteria.
Don't expose the area in sun ,apply sunscreen in the area .
Hope it was of help.
Let me know if you have any additional question.
