Are at-home red light panels actually effective?

Reviewer opinion is genuinely split. Some specialist-subreddit users and longer-form reviewers report visible skin improvement, reduced soreness, and better sleep after weeks of consistent use; others — including critical threads on r/SkincareAddiction and r/30PlusSkinCare — argue most at-home masks and panels are underpowered relative to clinical devices. Realistic expectations and consistent use are the recurring themes.
