How it Works: Wavelengths of red light that may help improve skin’s barrier function by improving its ability to retain key elements it needs to heal and generate new collagen after its production has slowed due to age or cumulative damage. Red light LEDs are also believed to target the skin’s oil glands to reduce cytokines, a class of pro-inflammatory substances believed to play a role in chronic acne.
Why you should consider it: May help reduce signs of aging, including wrinkles around the eyes; a better choice for those struggling with acne and wrinkles; minimal risk of side effects, especially when used without light-activating chemicals (this is common when done by a medical professional).
