Understanding Scars and Sun Damage
Scars form when the deep dermal skin layer gets damaged from injuries like burns, cuts, surgery or inflammation. Fibrous collagen tissue repairs these wounds creating scar tissue – the skin’s natural healing response.
But scars lack usual skin structures like hair follicles and oil glands, which can leave tissue feeling tight or tender. Scars also often differ pigment-wise from surrounding skin. Ultraviolet radiation exposure worsens these issues.
There are several ways to protect both new and old scars from further sun damage to support healing and prevent complications.
New Scars are Sensitive
In the initial year after injuries, scars go through remodeling phases working to repair wounds. During maturation they are especially vulnerable to reinjury and ultraviolet ray stimulation which sparks excess melanin production.
This expedites dark, uneven hyperpigmentation and thick, inflexible, painful scar tissue formation. Guarding early scars properly aids the delicate healing trajectory.
Aged Scars Still at-Risk
Over time with repeated UV harm, old scar tissue progressively degenerates through processes like molecular fragmentation and cross-link accumulation. Weak structural integrity follows.
Ongoing exposure also destroys vitamin A needed for collagen resiliency. Plus it inhibits fibroblast function – cells generating healthy scar tissue. Protecting both new and old scarring preserves integrity.
Minimizing Sun Damage on Scars
You can help scars heal optimally and maintain strength over time by shielding them from UV sunlight, especially during peak hours. Useful strategies include:
Covering Up
Wear sun protective clothing like wide-brimmed hats, tightly woven long sleeve shirts and pants over healed and healing scars when possible. Tight weaves ensure minimal ray penetration.
Seeking Shade
Stay in the shade under trees, umbrellas or canopies whenever outside for long with scarred areas exposed. Diffuse, reflected rays still damage so cover up if sitting awhile.
Avoiding Peak Times
Plan outdoor scar exposing activities in early morning or late afternoon when intensity of direct rays is lower to minimize harm. High noon is worst.
Using Sunscreen on Scars
Vigilant sunscreen use is crucial for scar UV protection. Not all products are created equal – choice matters.
Broad Spectrum Formulas
Ensure any sunscreen guards against both UVA and UVB rays plus visible light which also sparks pigmentation. Combination filters like zinc oxide and avobenzone provide this.
SPF 30+ Ratings
High SPF ratings of at least 30 provide sufficient scar protection, blocking over 97% of burning rays. But reapply often – coverage wears off over time especially with sweating and water.
Water Resistance
Seeking waterproof/sweat-resistant formulas helps maintain protection through wetness allowing safer pool time or beach days without frequent re-coating. They withstand moisture better.
Additional Scar Sun Care Tips
Keep these extra considerations in mind for comprehensive UV defense:
Moisturize Daily
Hydrating scar tissue with gentle moisturizers preserves supple mobility so scars don’t tighten up. Massage also breaks down thick collagen bands as they develop.
Reapply Sunscreen
Remember sunscreen wears off over hours. Re-coat every 2 hours of sun exposure or immediately after sweating, swimming or towel drying to maintain protective barriers.
Consider Silicone Sheeting
Applying medical grade silicone gel sheeting under sunscreen supplies added moisture and compression inhibiting overgrowth of rough, raised scars from UV damage and cross-link stimulation.
Taking a diligent, multifaceted approach builds formidable armor against excessive UV-related scar complications.
Special Considerations by Scar Type
Sun protection needs differ slightly depending on specific scar origin and traits. Account for these factors:
Surgical Scars
Long, straight, clean surgical scars often heal fast and neatly if shielded from sun during their reorganization period the first year. Deeper surgery scars need extra TLC.
Traumatic Scars
Messy, irregular traumatic scars from accidents, wounds or violence take longer stabilizing. Guard them vigilantly with compression sleeves when possible during this delicate period.
Burn Scars
Extensive burn scars lack usual skin structures that protect from UV damage escalating their risk exponentially. Keep them completely covered when out and use silicone gel.
Acne Scars
Post-acne scarring damages the dermal structure differently but still benefits from vigilant broad-spectrum sunscreen use to prevent hyperpigmentation issues.
Understanding scar origin helps customize suitable sunlight avoidance and protective measures during daily activities.
What to Avoid for Scars in the Sun
Certain products and behaviors undermine scar UV protection efforts. Steer clear of:
Tanning Oils
Oils help retain heat but offer no SPF benefits alone. The intense exposure while tanning greatly exacerbates scarring even years later. Healing scars fare the worst.
Reflective Surfaces
Water, snow and sand intensify UV ray exposure with reflective properties. If spending time around these with unclothed scars, vigilantly apply water-resistant SPF45 or higher sunscreen.
DIY Remedies
Kitchen ingredients like lemon juice, olive oil and vitamin E oil do not protect from UV damage. Rely on proper broad-spectrum sunscreen instead for scar coverage.
Managing Scar Hyperpigmentation
If scars already show dark discoloration from too much unprotected sun exposure, remedies can help lighten pigmentation.
Brightening Serums
Products containing brightening agents like vitamin C, kojic acid, azelaic acid, arbutin or niacinamide inhibit melanin production to gradually fade hyperpigmentation.
Chemical Peels
In-office chemical peels performed by dermatologists strip off pigmented upper skin layers revealing fresh scar tissue below with more even tone using exfoliating acids.
Laser Resurfacing
For substantial dark scarring not responsive to other remedies, vascular laser or pulsed light technology can destroy excess melanin deposits. Several repeat sessions may be needed for full benefit.
But ensuring adequate sun protection minimizes the need for these corrective treatments in the first place. An ounce of prevention truly outweighs the cure here!
FAQs
How long should new scars stay out of the sun?
Aim to shield new scars from sun exposure for at least one full year during the delicate tissue remodeling process. Sun can really exacerbate uneven texture and coloring.
What SPF is best for scars?
SPF 30 at minimum, but SPF 50 provides 98% UVB ray protection. Plus ensure the sunscreen is broad spectrum covering UVA, UVB and visible light which also darkens scars upon repeat exposure.
Do old scars still need sun protection?
Yes, aged scars still benefit from vigilant SPF coverage when uncovered to prevent collagen breakdown and increasingly uneven pigmentation over time from accumulating sun damage.
How can I fade dark scars from past sun exposure?
Using brightening skin care products with vitamin C, chemical peels and laser treatments can all help lighten brown hyperpigmentation on scar tissue by inhibiting melanin production in skin cells.
