The Long-Term Outlook for Your Child

As the initial wound of Aplasia Cutis Congenita (ACC) heals, your focus will naturally shift toward what your child’s skin will look like in the years to come. While the journey begins with an open wound, it ends with a stable scar that becomes a permanent part of your child’s physical story ^[1][2].

The Healed Appearance

Once the skin has fully closed (a process called re-epithelialization), the area will typically look like a shiny, smooth, and thin patch of skin ^[1][3]. Because the original layers of skin were missing at birth, the body repairs the area with scar tissue rather than regenerating normal skin ^[1][4].

A hallmark of healed ACC is permanent alopecia, which is the medical term for hair loss ^[1]. Because hair follicles and sweat glands develop within the skin layers that were missing, they are not present in the healed scar and will not grow back naturally over time ^[1][2].

Future Options for Cosmetic Improvement

For many children, a small hairless patch is barely noticeable and requires no further action. However, if the area is large or located in a highly visible spot, several surgical and non-surgical options can be considered as your child grows:

• Tissue Expansion: This is a common surgical procedure where a balloon-like device is placed under the healthy, hair-bearing scalp skin near the scar. Over several weeks, the device is gradually filled with fluid to stretch the skin. Once there is enough new skin, the scar is removed and the stretched, hair-bearing skin is pulled over to cover the area ^[5][6].
• Surgical Excision: For smaller scars, a surgeon may simply remove the hairless area and stitch the surrounding hair-bearing skin together ^[7].
• Hair Transplantation: Newer techniques, such as follicular unit transplantation, involve moving individual hair follicles from one part of the scalp into the scar tissue to improve hair density ^[8].
• Scalp Micropigmentation: This is a non-surgical option where medical-grade tattooing is used to mimic the look of hair follicles, making the hairless patch less obvious. This is an option reserved for late adolescence or adulthood, once the scalp has finished growing.

Daily Care and Protection

The skin over a healed ACC lesion is often thinner and more delicate than the surrounding skin ^[1]. You will need to take a few simple steps to protect it:

1. Sun Protection: Scar tissue is highly sensitive to UV rays and can burn or change color easily. Once your child is old enough, apply high-SPF sunscreen to the area or have them wear a hat when outdoors ^[9][4].
2. Moisturizing: Some healed scars can become dry or feel “tight.” Applying a gentle, fragrance-free moisturizer can help keep the skin supple.
3. Physical Protection: If the scar is very thin or located over a bone defect, your doctor might recommend extra caution during contact sports or high-impact activities.

A Healthy, Normal Life

It is important to remember that for the vast majority of children—especially those with isolated ACC—this condition is simply a skin-deep difference ^[10][7]. While the path to healing requires patience and careful monitoring, children with ACC typically grow up to lead perfectly healthy, active, and normal lives ^[11][7]. The scar is a testament to their body’s incredible ability to heal, and it does not define their future potential.
