How deeply light penetrates your skin

How deeply light penetrates your skin

Violet Light (400nm)

  • Typical use: Violet light sits at the border between blue and red light. It is used in skincare routines that focus on a clear, even complexion and on the appearance of fine lines.

Blue Light (450nm)

  • Typical use: Blue light stays in the surface layers of the skin. It is a common part of skincare routines aimed at a clear, calm-looking complexion.

Turquoise Light (490nm)

  • Typical use: Turquoise light is a mix of blue and green light. Many people choose it for sensitive skin and for a calm, balanced skin appearance.

Green Light (520nm)

  • Typical use: Green light is used with a focus on an even skin tone and on the appearance of dark spots, sun spots and hyperpigmentation, for a brighter, more uniform look.

Yellow Light (590nm)

  • Typical use: Yellow light is a gentle wavelength that is often discussed in connection with circulation in the skin. Many people use it in routines for sensitive skin and for a fresh, radiant look.

Orange Light (600nm)

  • Typical use: Orange light is chosen for dull, tired-looking skin. It is often part of routines that focus on skin tone, collagen and the visible signs of ageing.

Red Light (660nm)

  • Typical use: Red light penetrates more deeply into the skin. Research into photobiomodulation examines how it interacts with collagen and skin elasticity – topics many people associate with fine lines, wrinkles and a fresh skin appearance, which makes it a common choice for anti-ageing routines.

    Near Infrared Light (850nm)

    • Typical use: Although invisible to the naked eye, near infrared light penetrates deeper into the skin, muscles, and joints. It is therefore mostly chosen when the focus lies on deeper body areas – for example circulation and recovery as a fixed part of a training routine.
