What can I do for my hands after years of picking?

To treat scars from fingerpicking, it's indeed beneficial to keep your skin hydrated and moisturized. Here are a few steps you can follow:1. Cleanse the affected area with mild, fragrance-free soap and warm water to remove any dirt and bacteria.2. Apply a healing ointment or cream that promotes wound healing. Look for ingredients such as aloe vera, vitamin E, or silicone. These ingredients help to keep the skin hydrated and can also help reduce the appearance of scars.3. Cover the area with a bandage or a hydrocolloid dressing. This will help to protect the area, keep it clean, and maintain a moist environment which is beneficial for wound healing.4. Even after the wound has healed, continue to moisturize the area regularly. Keeping the skin moisturized helps to improve its elasticity and can reduce the appearance of scars.5. Protect the area from the sun as UV rays can darken scars making them more noticeable. Apply a broad-spectrum sunscreen or wear protective clothing.
If the scars are deep or not improving with home care? I may suggest treatments such as laser therapy, microdermabrasion, or chemical peels.
