The Role of Sun Protection in Scar Recovery

Ultraviolet (UV) radiation is one of the most common environmental factors affecting scar recovery and one of the easiest to manage with the right guidance.

Fresh scars are more sensitive to sunlight than normal skin. The newly formed tissue lacks mature pigment cells (melanocytes), making it more prone to discolouration, irritation, and long-term hyperpigmentation when exposed to UV rays.

Even brief sun exposure can darken scars and slow healing. That’s why consistent sun protection should be part of every patient’s recovery plan.

How UV Exposure Affects Scars

Recommendations for Patients

Healthcare professionals can help patients manage this risk with simple, evidence-based advice:

• Use broad-spectrum SPF 30+ sunscreen once the scar is fully closed

• Cover scars with protective clothing or a medical grade silicone strip for added UV protection

• Avoid direct sun exposure during peak UV hours

• Encourage long-term protection even months after the scar has closed and healed

By integrating sun protection into post-surgical care conversations, clinicians can significantly improve the long-term aesthetic and functional results of scar recovery.
