TEBISKIN Gly-C is the ultimate vitamin C serum. It is highly concentrated and rich in antioxidants. This ensures a perfect balance and helps prevent skin aging. Your skin becomes smoother and stronger overall.

Could your skin use a boost to combat skin aging or acne? Then this highly concentrated serum is perfect to use. The combination of AHA acid, pure L-ascorbic acid and ectoine ensures good preparation of the skin for a cosmetic treatment. These ingredients also help to tackle skin problems such as acne. The result is intensely hydrated skin and an even skin structure with a natural appearance. In addition, the addition of zinc ensures that cell growth is stimulated. Below we explain what the 'powerhouses' of Gly-C do.
  • 3-O-Ethyl Ascorbic Acid (Vitamin C Derivative): A stable form of vitamin C that helps brighten skin, reduce pigment spots, and provide antioxidant protection. Stimulates collagen production for firmer skin, improves skin texture and reduces signs of aging.

  • Acetyl Glucosamine, a building block of hyaluronic acid, supports the skin's natural exfoliation processes and works together with vitamin C to reduce dark spots. Helps reduce fine lines and wrinkles, improves skin texture and hydration.

  • Urea: A naturally occurring moisturizing ingredient that helps retain moisture in the skin and improve the skin barrier. Provides intensive hydration, softens dry and rough skin, and helps remove dead skin cells.

  • Retinol (Vitamin A): A powerful anti-aging ingredient that stimulates cell turnover, promotes collagen production, and reduces the appearance of fine lines and wrinkles. Improves skin texture and tone, reduces acne and provides more youthful looking skin.

  • Sodium Hyaluronate (Hyaluronic Acid): Attracts and retains moisture in the skin, making it an excellent hydrator. Helps hydrate and plump the skin, reducing the appearance of fine lines and wrinkles.


The serum comes in four bottles with freeze-dried powder in the cap. Remove the white seal from the bottle and turn the white cap down. Then shake the bottle well before use and unscrew the white cap. Then remove the yellow cap from the bottle and place the transparent plastic pipette on top. Please note: You must use an opened bottle within two weeks.

Apply TEBISKIN Gly-C every morning and evening to a cleansed face. Let it absorb thoroughly before applying your favorite day/night cream. We recommend TEBISKIN Gly-Clean for your daily cleaning.

  • Do you suffer from acne? Then we also advise you to use TEBISKIN Osk and TEBISKIN UV-Osk. Take a look at our affordable TEBISKIN Oily and Acne Prone Skin Kit.

  • Do you want to increase the anti-aging effect? Then we recommend TEBISKIN Reticap Face Cream and TEBISKIN Reticap-EL Night.
