Shoulder & Deltoid Keloids
The deltoid is a classic post-vaccination keloid site, with thick dermis and high movement.
Why this site is prone to keloids
The deltoid region is a prime vaccination site and a hotspot for post-injection keloids, particularly from BCG and smallpox vaccines. Shoulder skin overlies an area of significant movement and tension, and the dermis here is relatively thick. Keloids tend to be raised, firm, and pruritic.
- Standard injection site for many vaccines.
- Thick dermis with strong fibroblast response.
- Skin stretches with every arm movement.
Dermatologists often combine multiple modalities for site-specific keloids. Review each approach on its own page before discussing with a clinician.
- Steroid InjectionsDirect injection of corticosteroid (usually triamcinolone acetonide) into keloid tissue to flatten and soften the scar. Considered first-line for many keloid presentations.Read more →
- Silicone SheetsSelf-applied silicone sheets or gels worn over developing or existing scars. One of the most widely recommended first-line topical options for scar prevention and management.Read more →
- Red Light TherapyLow-level red (around 630-660 nm) and near-infrared (around 810-850 nm) light delivered at home with LED panels. Painless, non-invasive, and layer-safe — it complements virtually any keloid protocol and carries a second, well-documented benefit set for general skin health.Read more →
- SurgeryPhysical removal of keloid tissue by a dermatologic or plastic surgeon. Produces immediate volume reduction — but excision alone has one of the highest recurrence rates in all of dermatology (45-100%) because the trauma of surgery itself often triggers a larger keloid. Surgery is only a good idea when it is paired with an aggressive post-op adjunct protocol: steroid injections, radiation, pressure therapy, or a combination.Read more →

BestQool Pro100 Red Light Panel
Two-wavelength output targets the two most-evidence-backed bands for keloid photobiomodulation — 660 nm for fibroblast and TGF-β1 modulation in the upper dermis, 850 nm for deeper dermal collagen remodeling. The Jagdeo 2018 systematic review of 56 RCTs (≈4,920 participants) identified 700-850 nm as the most consistently effective range; the Pro100 sits squarely on that core rather than padding with weaker flanking bands. 100 dual-chip LEDs deliver 109 mW/cm² at 3 inches — irradiance comparable to panels twice the price.

BestQool BQ150 Half-Body Red Light Panel
Four-wavelength output (630, 660, 850, 940 nm) covers the research-backed red and near-infrared core for scar photobiomodulation. 150 dual-chip LEDs deliver 96.2 mW/cm² at 3 inches across a 21.3 x 14.3 inch panel — 27.8 x 18.7 inches of effective coverage at 6 inches. Best suited for people with multiple keloid sites who want one panel to cover chest, shoulder, or upper back in a single session.
