Hur länge huden blir röd efter blåljusbehandling beror på hur stark behandlingen är och vilken hudtyp du har. Men här är en allmän regel:
Typisk rodnad Varaktighet Mild behandling hemma (LED-masker, handhållna enheter):
0–2 timmar (vanligtvis ingen kvarstående rodnad).
Professionell behandling (hos en hudläkare eller klinik):
A few hours to 1 day (stronger devices may cause slight redness).
For sensitive skin/rosacea:
Up to 24–48 hours (if skin is reactive).
Why does it happen?
Blue light temporarily stresses bacteria and oil glands, causing mild inflammation.
Some devices also emit heat, which can increase redness.
How to Reduce Redness Faster
Apply Aloe Vera or a Soothing Serum (till exempel, centella asiatica, niacinamid).
You can also use a cold compress for 5–10 minutes to calm the skin.
Avoid products with active ingredients like retinol, acids or vitamin C for 24 hours after treatment.
Moisturise and use SPF (if going outside).
When to WorryIf the redness lasts more than two days, or if it becomes swollen or burning, or looks like a sunburn, see your dermatologist (this is rare, but possible with overuse or sensitive skin).
