Stitches are medical sutures used to bring together the edges of a wound or incision. Their primary goal is to promote effective healing, reduce infection, and minimize future scarring.
Risks of Tanning with Stitches
Exposing a wound with stitches to ultraviolet (UV) radiation poses several risks to the healing process. UV light can damage delicate new skin cells, slowing healing. This exposure can also intensify inflammation around the wound site, delaying recovery.
Sun-damaged skin becomes more vulnerable to bacterial invasion, increasing the potential for infection. UV radiation can dry out the wound, potentially forming scabs that create an environment where bacteria can thrive. Higher environmental temperatures, often associated with sun exposure, can also promote bacterial growth, elevating the risk of surgical site infections.
The impact on scar appearance is a major concern. UV exposure stimulates melanin production, leading to hyperpigmentation, which is a darkening of the scar tissue. This discoloration can make the scar more noticeable and can become permanent. In some cases, UV radiation can contribute to the formation of raised, thickened scars like keloids. Furthermore, UV light can break down collagen, a protein essential for the scar’s strength and elasticity, weakening its structure.
Different Tanning Methods and Your Stitches
Both natural sun exposure and tanning beds emit UV radiation, carrying the same risks for stitched wounds. Even covering the wound with thin clothing may not provide sufficient protection, as UV rays can penetrate many fabrics.
Non-UV tanning methods, such as spray tans and self-tanners, bypass the dangers of ultraviolet radiation. However, applying these products directly over an open wound or stitches is not recommended. Chemicals in tanning solutions could cause irritation to sensitive healing tissue. Applying the product might also disrupt the delicate wound or introduce bacteria. Wait until the wound is fully closed and stitches are removed before considering these alternatives.
Caring for Your Skin After Stitches Are Removed
After stitches are removed, the new skin remains fragile and susceptible to UV damage. This vulnerability to hyperpigmentation and other sun-induced issues can persist for several months, ranging from six months to over a year, as the scar matures. Consistent sun protection during this period is important for optimal scar appearance.
Applying a broad-spectrum sunscreen with an SPF of 30 or higher is recommended for any exposed scar tissue. Mineral sunscreens, containing zinc oxide or titanium dioxide, are often preferred for sensitive skin as they create a physical barrier that deflects UV rays. Sunscreen should be reapplied every two hours, or more often if swimming or sweating.
Wear protective clothing made from tightly woven, loose-fitting fabrics or those with a UPF (Ultraviolet Protection Factor) rating of 50. Limit outdoor exposure during peak UV hours, typically between 10 AM and 4 PM. Silicone sheets or gels, often used for scar management, can also provide a physical barrier against the sun while aiding in scar flattening and fading.
