Within the first week I noticed my skin start to soften and brighten… darker areas around my upper lip lightened, one is non existent… I will not be without this.

Showing amazing results within the first month… it brightens almost immediately and does not irritate or cause redness… I absolutely love it!

This is hands down the best one I’ve ever used… I saw results within a week and it’s only gotten better with time. 10/10 recommend!

The Problem

Why most serums don't deliver

Vitamin C serums oxidize quickly, turning dark orange in the bottle and losing efficacy before you've finished the bottle.
Uneven skin tone and visible aging are two separate concerns that typically require two separate routines.
Most Vitamin C serums don't deliver enough antioxidant potency to meaningfully defend against daily pollution and UV exposure.

The MDAiRE™ Solution

Formulated to actually work

Vitamin C-FK combines a quad-form Vitamin C blend engineered for stability with airtight nitrogen-lined chamber packaging so every drop stays potent from first use to last.
Kojic Acid and a peptide-supporting blend target pigmentation and collagen degradation simultaneously. One serum delivers brightening and anti-aging results together.
Vitamin C-FK is formulated with a full antioxidant defense complex. When applied each morning, it neutralizes free radicals before they trigger the inflammatory cascade that leads to visible skin damage.

love, Love, LOVE this stuff!
I was looking for a Vitamin C serum for mature skin and I ordered it after watching a review from Dr. in the industry recommended this product. I ordered the smaller size just to try it and I was amazed with the results. I use it every morning after cleansing on dry skin and then I wait five minutes before applying my other serums, moisturizer and SPF. Within the first week I noticed the texture of my skin start to soften and brighten. I had a few darker areas around my upper lips that actually lightened, one is non existent and the other is barely visible. As a self-proclaimed skin care junkie, this is one product that I will not be without. Needless to say, I’m on to the large size now!
