  • AMAZING VITAMIN C

    It’s my second time buying this serum. I immediately noticed a difference on my skin within a week of using the 20% VITAMIN C BRIGHTEN + FIRM SERUM. It gives a lit from within look. My hyperpigmentation from my occasional hormonal acne fade quicker. Love love love!!!

  • SO FAR SO GOOD !

    The texture is gooey and thick for it is a waterless base, but if you apply it after wetting your face with toner the serum sinks in nicely, leaving a slight glowy finish. It did not irritate my skin whatsoever and I feel it protects my face all day long from pollution and sun damage due to the high level of antioxidants in the serum.

  • RICH & NON-IRRITATING

    It's a very pleasant serum, rich in texture but not doesn't feel heavy. Use it for a couple of months and noticed that my post-acne spots are fading away.

PRODUCT INFORMATION

Our daily serum harnesses the cumulative effect of 20% Vitamin C, 2% Orange Extract Complex derived from citrus cells, and 0.05% Dimethylmethoxy Chromanol to create a targeted effect for all skin types. It forms a protective shield against daily external aggressors and pollutants while paving the way for brighter, firmer-looking skin. This antioxidant-rich formula promotes radiance-enhancing elasticity and fading dullness. Over time, skin glows with a brilliant smoothness.

Its waterless base ensures that the colour of this formula does not change, and it stays potent. The unique formula has an initial balm-like quality (due to pure diamond powder that imparts instant radiance) that may feel thick at first but melts instantly in contact with damp skin.

I wanted to create a serum that would impart instant radiance while providing brightening and firming action. Part of what makes this serum unique is its Diamond Powder base which gives your complexion a lit-from-within glow that gets better with daily use.

Awesome

My best product so far! I purchase every time there are some discount otherwise I can’t afford it, but seriously it leaves your skin glow. You will start receiving compliments of your skins after two weeks using it. I can stay without! Remember to use with a mist or splash of water.

Great Vit C Serum

Great Cit C serum if your skin is dry and sensitive. Recommend to apply on a damp skin otherwise can be a bit sticky. So far no sensitive reaction although might be a bit too rich for my combination skin.
