Inactive Scars: Causes, Treatments, and Baby Safety

Inactive scar

Thank you, Dr.
Lu, for your previous explanation.
What is meant by "inactive scar"? If it is not caused by amniocentesis during the fetal period, what other reasons can lead to the formation of an "inactive scar"? Can this scar be congenital? Besides amniocentesis, I can't think of any other reasons that could cause such a scar.
Also, you mentioned applying "L-ascorbic acid ointment"; can it be used on an 11-month-old baby? Where can topical ointments be purchased?

A silver scar is referred to as an inactive scar, while an active scar is red, raised, and may be painful or itchy.
L-ascorbic acid (vitamin C) is a medical cosmetic product that can be found in drugstores.
Scars on children's skin are more likely to occur during their growth process.

More Info

Inactive scars, also known as atrophic scars, are a type of scar that appears depressed or indented compared to the surrounding skin. These scars can result from various causes, including but not limited to, acne, chickenpox, or injuries that damage the skin's deeper layers. Unlike hypertrophic scars, which are raised and often red or dark in color, inactive scars do not exhibit active inflammation or excessive collagen production.

In the context of fetal development, inactive scars are not typically caused by in utero factors unless there is a specific injury or condition that affects the skin during pregnancy. For instance, if a mother experiences a skin condition that leads to scarring, it may not directly impact the fetus unless there is a significant systemic issue. However, congenital conditions can lead to skin abnormalities, but these are usually not classified as inactive scars.

Regarding your concern about the use of topical medications like L-ascorbic acid (often referred to as "left-handed C cream" or vitamin C cream), it is essential to consider the safety of such products for infants. Generally, topical vitamin C is considered safe for use on babies, as it is a naturally occurring antioxidant that can help improve skin texture and promote healing. However, it is crucial to ensure that the product is specifically formulated for infants and free from harmful additives or fragrances that could irritate their sensitive skin.

When it comes to purchasing topical medications, they can typically be found at pharmacies, health stores, or online retailers. It is advisable to consult with a pediatrician or dermatologist before applying any new product to your baby's skin, especially if they have sensitive skin or any existing skin conditions.

In summary, inactive scars can arise from various causes, and while they are not typically linked to fetal development unless there is a specific injury, they can be managed effectively with appropriate treatments. Topical vitamin C can be a safe option for infants, but always consult with a healthcare professional to ensure the best care for your baby.
