Pressure ulcers, also known as bed sores, are damages to the skin usually between the surface in contact with the patient and bony projections. Wiki authors cite poor circulation and biofilms as components of the pathology. The noun decubitus refers to the laying down position and is often used to describe sores acquired in that position. The featured image shows the four stages of these ulcers. Most studies used laser light rather than the LED light panels commercially available direct to consumers. One would think that the convenience of such a panel at stage 1, or before the ulcer even starts, would provide some benefit. Sometimes pressure ulcers can be infected with maggots as shown in this YouTube video. Some of these studies were inconsistent, others showed some amazing results. In these studies patients prone to bed sores, are the elderly and those with spinal cord injuries (SCI). Red Light Therapy Home sells a very affordable panel of LED lights as well as a suggestion for dealing with pressure ulcers in conjunction with standard of care and a licensed healthcare provider. Note that these suggestions target areas where pressure ulcers commonly form.
Position and where to shine the light:
- Aim the light directly at the bed sore and the surrounding margin of skin (about 1 to 2 inches around it)
- Because the Mini is a small, targeted panel, treat one sore at a time, if you have more than one, split the 15 minutes between them (for example, 8 minutes on the worst area, 7 minutes on the second area)
- Common locations and easy positioning ideas:
- Tailbone or sacrum area: lie on your side so the sore side faces the panel, or stand with your back to the panel so the sore area is the closest surface to the light
- Hip area: lie on your side with the sore facing the panel
- Heels or ankles: sit with your foot propped on a stool or chair so the sore faces the panel
What this targets: Supports local circulation and cellular energy in the tissue, helping the skin recovery process
IMPORTANT PRACTICAL NOTES FOR BED SORES
- Keep the area clean and dry before the session, and avoid shining the light through thick bandages (thin, transparent dressings are usually fine, but do not disturb a dressing plan given by your clinician).
- If the area feels too warm or looks more irritated after sessions, increase distance to 2 feet and reduce to 10 minutes for the first week, then build back up as tolerated.
- If you notice signs of infection or worsening such as spreading redness, heat, swelling, foul odor, pus like drainage, fever, or increasing pain, please seek medical care promptly. Bed sores can progress quickly and sometimes need professional wound management.
WHY THIS PLAN IS A GOOD FIT
- The Wound Healing mode is designed specifically for tissue repair support, using a blend of red and near infrared for cellular energy and circulation support, plus a controlled amount of blue for skin surface support.
- The 1 to 2 feet distance and 15 minute session time are set to give a useful dose without overdoing it, especially important for fragile or compromised skin.
When should I use the “Full Power” mode?
Complex Conditions:
Multifaceted Health Issues: For conditions where inflammation, pain and tissue repair are all concerns (healing large or complex wounds where multiple layers of tissue are involved), full power might be used to address multiple aspects simultaneously.
Mode Settings: Red (633, 660nm, 100%), NIR (810, 830, 850 nm, 100%), Deep NIR (1064 nm, 100%), Blue (OFF), Pulse (OFF)

What I find very encouraging is the use of red light to increase . This paradox was introduced in the cellulite post. This post addresses the paradox of how red light can promote wound healing and yet reduce cellulite, that is also a product of collagen production. The finding by Taradaj 2018 that 658nm red light increases TGFβ1, the collagen growth factor is particularly exciting. Does this mean that red light can strengthen skin before pressure ulcers develop? And promote blood flow before the damage occurs in the first place? This user who is not elderly or with a SCI, it sure feels good!
