Have you ever given someone a handshake and your hands were bruised? Lol😜
As if you scraped with a sandpaper 😂
Excessive dryness and accumulation of dead skin cells is the cause.
All the person needs do is exfoliate using a scrub daily. Preferably at night.
Then moisturise with an oil- rich moisturiser or butter. Cover up with a cotton handglove and leave overnight.
If consistently done, in a week there will be noticeable changes as the hands will become soft and smooth.
You can still try it even if your hands are not so hard😉
