3) Is Gua Sha safe for all skin types?

    • Gua Sha is generally safe for most skin types, but it's important to use it gently and avoid excessive pressure, especially on sensitive or broken skin (i.e Skin with a lot of acne).

7) Should I use this on my eyes or eye bag areas?

    • This DermaCrest Gua Sha device is not designed to be used around the eyes unless you are experienced at treating these areas. DO NOT use this device on the eye lids as this is a very sensitive area, and can lead to injury. Always use precautions and consult with a professional prior to treating near or around the eye area.

8) Do I need to use oil or a moisturizer with Gua Sha?

    • Using a facial oil or moisturizer can provide a smoother glide and enhance the benefits of Gua Sha. It also helps prevent friction on the skin. Try using your favorite serum or lotion to pretreat your skin prior to starting your routine.

9) How many LED's does this device have and what is the power rating?

    • For such an incredibly small device, we have managed to squeeze 18 LED's into it (9 LED's per side). The total of 18 LED's produce a total of 5 watts of power. This makes the DermaCrest very effective in close proximity to your skin.

  • The DermaCrest massager produces Red light therapy at a wavelength of 630nm, which is a form of low-level light therapy that uses red LED light to treat various conditions without harmful or dangerous effects. This therapy stimulates the mitochondria in cells, promoting the production of adenosine triphosphate, which is essential for cellular function and repair. Here are the benefits of red light therapy at 630nm:
  1. Skin Health: It promotes collagen production, reduce wrinkles, and improve skin tone and texture, and removal fine lines.
