Red light therapy masks, a beauty technology championed by celebrities such as Charlize Theron and Kim Kardashian, are seeing increased attention as Amazon Prime Day offers discounts of up to 47%.

Theron, an advocate for the devices, stated in April on the "Will and Woody" podcast that she uses red light masks "at all times," attributing their effectiveness to a greater impact than "any lotion or cream." She joins a list of notable figures, including Halle Berry, Kim Kardashian, and Kris Jenner, who have expressed their approval of the beauty tech. These masks are credited with minimizing wrinkles, stimulating collagen production, and reducing inflammation and skin redness.

Several models are available at reduced prices during the Prime Day sale event, which runs from June 23 to June 27. The Wavytalk red light mask, described as a well-rated entry-level option, is available for under $100. This device aims to enhance skin radiance and decrease breakouts, with one user noting an improved skin tone after only a few sessions. The Ulike red light mask, a high-end model, is designed for smoother, brighter skin, targeting fine lines, elasticity, wrinkles, discoloration, and redness. Ulike claims its device delivers results in eight minutes daily through four modes: glow, firm, rejuvenate, and clear. Amazon reviews praise its comfort and rapid, noticeable effects. The Inia Red Light Mask, another budget-friendly option, offers different treatment cycles for blemishes, dullness, or wrinkles and can be used for up to 30 minutes per session. Users report brighter, smoother, and more refreshed skin with consistent use, noting it as a relaxing part of their routine. The CurrentBody red light therapy mask, which includes chin coverage, is FDA-cleared and clinically proven to reduce visible wrinkles while improving skin brightness and firmness. Kim Kardashian has publicly shared her enthusiasm for this model, calling herself "obsessed" in 2023. Halle Berry and Kris Jenner are reportedly fans of the Dr. Dennis Gross red light mask, which is also FDA-cleared. This model is designed to boost collagen and skin density, smooth wrinkles, and address sun damage, and is suitable for all skin types.

Amazon Prime Day is an exclusive event for Prime members. Those without a membership can sign up for a 30-day free trial to access the sale. This year's Prime Day has been moved to June, with Amazon introducing new incentives such as sweepstakes and gift card opportunities. Historically, Prime Day sales are opportune for discounts on technology, beauty products, and accessories.
