What is it: Mega-C Dual-Phase Serum is Kate's revolutionary serum packed with vitamin C and bioactive phyto-omegas 3, 6, 9, and 7. Mega-C is formulated to help improve the appearance of skin firmness, elasticity, texture, and smoothness, as well as increasing luminosity, hydrating, and reducing the appearance of fine lines and wrinkles.

Who is it for: It's ideal for anyone who is looking to help improve skin firmness and luminosity, improve skin elasticity, and reduce the appearance of fine lines.

Why is it different: This dual-phase system keeps the vitamin C matrix and the omega serum in separate chambers until use, helping the vitamin C to remain in a stable form. When combined on the skin, the water-based omega serum prepares the skin to receive the vitamin C matrix.

In clinical studies, after just one use, 100% of women showed a significant improvement in the appearance of skin firmness and elasticity and 100% of women showed a significant improvement in skin moisture or hydration. After four weeks, 88% of women showed significant improvement in skin texture and smoothness, and 81% of women showed significant improvement in the appearance of skin-tone evenness.

How do I use it: Use once a day in the evening. Press both pumps with even pressure to dispense product equally. Apply to clean, dry face and neck. Allow serum to absorb into skin before applying other products.

Mega-C is an innovative formula with micronized 10% vitamin C and L-ascorbic acid, which helps maximize the stability of the vitamin C. The white serum formula does not contain water and therefore acts differently than other formulas. If you experience a problem dispensing, please firmly tap the bottle upside down on a hard surface several times before using. This will help it dispense more easily.

You are now on your way to the appearance of firmer, more radiant skin.

From Kate Somerville.

Rated 1 out of 5 by NIce Idea There are a few women who didn't seem to have a problem with the dual pumps. But more than a few customers have had a problem with the pumps, including me. In quite a bit of time, there appears that no change in the delivery system has been made. The dual pumps seem to cause a lot of frustration, and I don't understand why Somerville doesn't do something to stop this problem.....two bottles? a formula already mixed together which doesn't lose it's efficiency? I don't know. But when this many people have problems with the dispenser, it just LOSES customers by frustrating them! This problem has gone on and on for some time and no fix has yet been offered. It's a shame. So many do not know if the product, itself, would have been good or not! But they'll probably never buy another Somerville product! 08-31-16
Rated 5 out of 5 by 2+ Yrs and Still Seeing Improvements This product really works well. I've been on auto-delivery since the beginning and I'm still seeing improvements. Tip on the pump issue...take the bottom off and use a pen to push up on the interior tube while holding down the pump. This squeezes any air pockets out of the tube and allows you to get every drop. Problem solved!!! :) 05-26-16
Rated 5 out of 5 by GREAT PRODUCT This product works. I have been using it for well over a year, and I do notice good results. A couple times when I started a new container, there was a little reluctance for the product to release from the pumps, but after giving it a few shakes and a little thump, it started with no problem again until empty. I LOVE this product and do not want to be without it. 09-21-15
Rated 5 out of 5 by GREAT PRODUCT ESPECIALLY FOR SENSITIVE SKIN I have very sensitive skin, so I used this just hoping my skin would not rebel. It didn't rebel; it flourished. I put Kate Somerville's RetAsphere with this, and together they were a great duo. Again, no problem with sensitivity. I have eliminated brown spots, great skin tone and great hydrated skin. I don't even need to use a moisturizer. Don't let the pump issues stop you from trying this. Mine worked fine. My search is over. Others have noticed the changes. You can't ask for more than that. 02-21-15
Rated 1 out of 5 by Dissapointed I orderd this product and after 4 uses the pump on one side won't work and there was not enough serum in the other side. I returned it and Q gave me a new one and the new one had the same problem. This is definitely a manufacture problem. The product itself was marginal , I have used better products in the past. Would not recommend this . 08-03-14
Rated 2 out of 5 by Waste of $$$$ No results at all after 60 days. I get better results of products I buy over the counter. 07-28-14
Rated 2 out of 5 by Not good enough Sorry, I love some of Kate Somerville's products -- especially the ExfoliKate -- but this one just doesn't work. It didn't leave my skin any smoother or brighter, and for the cost, it just isn't worth it. I wasn't expecting miracles here either. I would have returned if I could have. I think Perricone's Vitamin C Concentrated Restorative Cream is the best Vitamin C product I've used. 07-15-14
Rated 3 out of 5 by Poor applicator I do love the product itself,but the applicator it is in I don't. The first one I sent back as a defect because one side pumped out the serum & the other side stopped working after about five days. So I sent it back & asked for a replacement. The replacement was fine for about three weeks ( use it once a day & love it# . Now the same, one side is pumpimg serum with no problem, the other # same side as the one I sent back) side doesn't go down all the way & pumps nothing. I know the one side is not empty. Anyway, even though I love the Serum, I won't order it again. 07-08-14
