An ideal hand is soft and smooth, with tapering fingers. It tends to have firm wrist, supple palm, and well-kept nails and fingers. Proper manicuring, massage and cleanliness can help to achieve that.
When you wash dishes, wear rubber gloves to protect the hands. You can use fresh lemon to remove stains, whiten the skin and cleans the nails. After washing dishes, you should use Vaseline or cold cream. Vaseline can protect the finger nails, it can also alleviate the dryness.
Whenever washing hands, do not wear rings or jewelry, because soap and moisture will be stuck there.
