We’ve all heard the phrase “sunshine is the best medicine,” but when it comes to scars, sunlight can actually be your worst enemy. Whether you’re healing from acne, surgery, stretch marks, or a kitchen mishap, exposing your scars to the sun can slow healing, darken pigmentation, and even make them permanent. This is where smart scar care begins by understanding the damaging role of UV rays on scars and how to prevent it.
In this blog, we’ll uncover the science behind why the sun can worsen scars, how to protect healing skin, and how products like Mederma Scar Cream with SPF can help restore your skin’s beauty while safeguarding it from harmful rays.
When your skin gets injured be it through a cut, burn, surgery, or acne it goes through a natural process of healing. This healing skin is not yet fully formed; it’s thinner, more sensitive, and lacks proper melanin distribution. That’s why it reacts differently to the sun.
Hyperpigmentation
The sun’s ultraviolet (UV) rays stimulate melanin production, which can cause scars to darken making them more visible over time. This condition is called post-inflammatory hyperpigmentation. While it’s more common in people with medium to dark skin tones, it can affect anyone.
Delayed Healing
Prolonged sun exposure can break down collagen and elastin, key components in the scar healing process. This not only delays healing but may lead to rougher, thicker scars.
Permanent Discoloration
Exposing a healing scar to the sun especially in the first 6–12 months can cause permanent discoloration. Even the best scar treatment products may not reverse sun-induced pigmentation. The Effects of UV Damage on Skin Repair Science
UV radiation comes in two main types: UVA and UVB. Both play a role in sun damage scars. UVA rays penetrate deeper and damage collagen, while UVB rays cause surface burns and hyperpigmentation. Healing scars lack the natural defenses of intact skin, making them more susceptible to both.
That’s why dermatologists stress the use of sunscreen for scars ideally SPF 30 or higher and recommend reapplying every two hours if you’re outdoors.
In short everyone. But especially if:
• You’ve had recent surgery, including C-sections or cosmetic procedures
• You’re dealing with acne marks or pimple scars
• You have burns, stretch marks, or old scars that have recently resurfaced
• You’re treating your scars with scar gel or scar cream that increases skin sensitivity
• You love outdoor activities hiking, swimming, running, gardening
Whether you’re chasing a mountain summit or simply lounging by the beach, protecting your scars is essential to avoid long-term discoloration or thickening.
You don’t need to be in direct sunlight to suffer UV exposure. Some common scenarios include:
• Cloudy days: Up to 80% of UV rays still penetrate clouds
• Through glass: Driving or sitting near windows can expose you to UVA rays
• Reflected rays: Sand, water, and snow can reflect and intensify UV exposure
That’s why protecting scars from sun isn’t just about beach days daily protection is crucial.
Use SPF-Infused Scar Creams
Look for products specifically designed for healing scars with built-in sun protection. For instance, Mederma Scar Cream + SPF 30 combines advanced scar care technology with reliable UV protection. It helps improve the texture and color of scars while shielding them from sunlight.
Reapply Sunscreen Frequently
A one-time morning application isn’t enough especially if you’re sweating or swimming. Reapply every two hours. Carry a travel-sized sunscreen or scar cream with SPF in your bag for on-the-go protection.
Cover Up with Clothing
Clothing, hats, and scarves can provide a physical barrier. Opt for breathable, UV-protective fabrics if you’re spending long hours outside.
Avoid Peak Sun Hours
When UV radiation is at its maximum, between 10 a.m. and 4 p.m., try to avoid being outside or in locations with shade.
Avoid Tanning Beds
Artificial tanning can worsen scars just as much as natural sunlight. Even if you’re aiming for a golden glow, it’s a big no-no for scar healing.
