C-Bright Dark Spot Corrector fades the look of dark spots (88% brighter-looking, 77% improved dark acne scars at eight weeks in a 34-woman study), Facial Resurfacer polishes twice a week, and Microbiome Defense Daytime Moisturizer SPF 15 finishes morning skincare. At week eight in ImagePro image analysis, 88% of 34 C-Bright participants improved in brightness; 77% of the dark-acne-scar sub-panel (n=13) improved in that appearance endpoint.

In an independent eight-week study of 34 women using C-Bright Dark Spot Corrector, 88% showed improved skin brightness, measured by digital image analysis compared with baseline. In an independent study, C-Bright improved the appearance of hyperpigmentation by 2.6% at 4 weeks. In an independent study, C-Bright improved the appearance of hyperpigmentation by 2.5% at 8 weeks. Seventy-six percent of subjects in the C-Bright hyperpigmentation sub-panel improved at the measured endpoints. In an independent study, C-Bright improved the appearance of dark acne scars by 1.2% at 8 weeks. At week 8, 77% of participants in the dark-acne-scar sub-panel showed image-analyzed improvement in the appearance of dark acne scars with C-Bright Dark Spot Corrector. In an independent study, C-Bright evened the appearance of skin tone by 0.3% at 8 weeks.

How does C-Bright work on dark marks?

In the eight-week image-analysis study, C-Bright improved measured brightness at four and eight weeks, the appearance of hyperpigmentation at four and eight weeks, and skin-tone evenness and the look of dark acne scars at eight weeks. C-Bright is a cosmetic discoloration treatment, not a treatment for active acne or indented and raised scar texture. Its strongest fit is the look of lingering color: dark spots, uneven-looking tone and dark marks left after a blemish. Read the C-Bright Clinical or see the customer results.

How do I use C-Bright for dark marks?

Press the side button to draw the liquid C-Bright Dark Spot Corrector into the dispenser dropper. Dispense a few drops into hand and apply directly onto cleansed skin before applying serums and moisturizer. For daytime, always follow with a sunscreen. May be used AM & PM. Optional: You can add a few drops of the C-Bright to your preferred serum or moisturizer. Avoid simultaneously using Vitamin C when using Benzoyl Peroxide and Retinol. For external use only. Avoid direct contact with eyes. By day, that sunscreen can be Microbiome Defense Daytime Moisturizer SPF 15; see where SPF goes. Complexion color can even the visible finish while the treatment has time to work.
