I've been using the red light therapy device for nearly two weeks now. The device appears to be well-crafted and sturdy. Each day, I've been applying 15-minute treatments to my face with the aim of boosting collagen production. Since skin cells typically regenerate over the course of about a month, I haven't noticed any improvements yet. However, I remain optimistic, especially given the device's apparent potency—I can feel it generating internal heat in my skin. Additionally, the device's price point is quite appealing, especially considering that similar products on the market are priced at least twice as high.
