What causes peeling and scratches on a doll's skin? And how can they be repaired?

Causes and Solutions for Skin Peeling or Tears:

1. Dry Skin from Cleaning:

• Frequent use of soap can extract the natural oil from the doll’s skin, causing it to become dry and prone to peeling.
• Solution: 
  Apply baby oil to replenish the oil on the doll's skin. Some customers also find that Vaseline can help in these situations.

2. Scratches from Friction:

• Because the doll is relatively heavy, scratches may occur from friction with other objects during use or cleaning.
• Solution: 
  For serious scratches, use TPE adhesive from the repair kit or a soldering iron to fix the damage.
