Some readers in Chelsea, Michigan deal with redness and breakouts at the same time. Light-based options come up for both. For one overview of the acne side, see lasers, lights and acne.
When light is on the table for acne
dermnetnz.org says: "Laser and light therapy provide useful options for patients with acne that persists despite medical therapy , who experience side effects to a medication, or who have difficulty adhering to medical treatments." Three situations are named: acne that persists, side effects, and trouble sticking to a treatment.

pmc.ncbi.nlm.nih.gov covers the redness side: "IPL has also been shown to be an effective treatment for the telangiectasias and background erythema/flushing seen in patients with erythematotelangiectatic rosacea." A guide to rosacea diagnosis and treatment gives the wider picture.
