Guinot Newhite Serum Eclaircissant Vitamin C Brightening Serum 14 Day Treatment 23.5ml + 1.5g / 0.80 oz. + 0.05 oz.

Guinot Newhite Serum Eclaircissant Vitamin C Brightening Serum is an intensive 14-day treatment designed to promote a clearer, more even-looking complexion. The lightweight serum is powered by Melanoxyl and pure vitamin C, introduced at the last moment to help maintain potency. Together they work to reduce the appearance of dark spots, support protection against free radicals and encourage a brighter, more radiant finish on the skin. The texture feels fluid and comfortable, making it easy to layer under day or night cream without feeling heavy or sticky.

Suitable for all skin types, particularly those concerned with uneven tone and visible discolouration, this serum fits seamlessly into a targeted brightening routine. Used morning and evening on cleansed skin, it helps to refine the look of the skin’s texture and promote a fresher, more luminous appearance over the course of the treatment. The formula is ideal as a seasonal or occasional boost whenever the complexion looks dull or lacklustre and needs a focused brightening step.

How to use
How to Use:
Prepare the product by adding the enclosed pure vitamin C to the serum bottle and mixing well. Apply the serum to thoroughly cleansed, dry skin. Gently smooth a small amount over the face, and where desired the neck, before your usual day or night cream. Repeat morning and evening for the duration of the treatment.

Frequency:
Use morning and evening as a 14-day treatment course, according to the product instructions.

Application Technique:
Dispense a few drops into the palms or fingertips, then apply in light dabbing or smoothing motions over the face, avoiding the eye contour. Allow the serum to absorb fully before applying moisturiser and, in the daytime, follow with an appropriate SPF.

Best Practices:
Apply to clean, dry skin and use thin, even layers. Combine with brightening day and night creams if desired to support a more radiant-looking result. Store the mixed serum in a cool, dry place and use within the recommended time after activating the vitamin C.

Safety Tips:
For external use only. Avoid direct contact with eyes and eye contour. If irritation occurs, discontinue use. Keep out of reach of children and follow any additional guidance on the packaging.
