It is important to point out the differences between a red light-only bed and a sunbed that emits both UV and red light. “Red light therapy without UV is a very different proposition,” confirms consultant dermatologist Dr Derrick Phillips. “It is generally considered safe and may help with things like inflammation, wound healing and improving overall skin tone. However, the results do tend to be subtle and I always remind patients that it’s not a quick fix.” Dr Beibei Du-Harpur, scientific engagement lead at The Skin Diary, agrees: “More clinical evidence is needed to confirm the effectiveness [of red light] as a treatment for the skin, but there have been promising small studies from a skin ageing perspective.”
