"I have lines on my body where I applied a hot water bottle?"

It is common to develop lines on the skin after applying a hot water bottle. To help with this, you can use a fragrance-free moisturizing cream like Base Glaxal, Cerave, Cutibase, or Aveeno at least three times a day. Use a fragrance-free soap like Dove, avoid hot water in the shower, and gently pat dry instead of rubbing the skin. It takes several weeks for the skin to fully heal and mature. Remember to apply moisturizer right after showering to retain moisture. If you have any other questions, feel free to ask.
