Love this

I was recommended this during my first Halo treatment. For years I’d been using SkinCeuticals CE Ferulic, which is undoubtedly a wonderful product. IS Clinical Gene XC Serum has a lot more to it, not to mention a higher level of vitamin C. I have to say my skin looks better! I am now a huge fan of the entire IS Clinical line. After struggling to find products that worked for my sensitive skin and rosacea, that will still be active in treating aging skin, I have found the brand!

One of my favorite products

Love how this product makes my skin glow. I feel a difference in skin texture and softness whenever I use it! I think it has helped significantly with sun spots as well.

No irritation, no improvement, bad dropper

I tried the GeneXC serum to see if it would help my aging sensitive skin. It did not sting or cause irritation. There was no improvement in my face skin. In the 0.5 oz. bottle, the dropper does not reach the bottom of the bottle. For the last 3–4 applications, I decided to pour the serum into my hand and apply it.

Glad I switched to this!!

I had been using a vitamin c &e serum from a different brandfor several years and it did help my skin quite a bit. My friend got this iS clinical genex serum and her skin looked amazing. I’ve only been using this for 2 weeks but it has improved my skin. My skin is so bright, clear, smooth, and it just glows. This serum glides on so nice and spreads a long way so you don’t need much. I like that this serum has a high 20% of vitamin c and my skin adjusts well to this one. I definitely recommend this serum, you won’t regret it!

Pretty Amazing

I purchased this for my husband and forgot all about it until after about a week when I saw a significant difference in his skin Sun spots were fading and he actually had a glow to his skin. The only thing is it does make you more photosensitive so just remember to wear a good sunscreen.

Beyond My Expectations

I'm starting my second bottle of Genxc and can't say enough good about it. The host of ingredients is impressive which is likely why it does so much. My skin is more even color with fewer pink areas and two sunspots that can barely be seen any more. My pores look smaller and overall skin on face and neck appears tighter. I've been able to use just this one serum now instead of 2-3 I've been using. One caution: use a drop or two at a time as it's watery. You really don't need more than that. I use a couple drops on each side of my face for full coverage plus two on my whole neck and down.

My aesthetician recommended this serum and I’d say I love it! It tightens my face and makes me feel refreshed.

This serum does NOTHING

I generally like IS Clinical and decided to try this new serum. I am so disappointed ...This serum does nothing sadly.

Can’t see a difference yet

It caused me to break out at first. I just mix it with my moisturizer now and I don’t break out anymore. If you’re sensitive to vitamin C serums, I would recommend doing the same rather than placing it directly on your skin. Over all, I haven’t seen too much a difference since using it, but for some reason I enjoy having it as part of my routine so I will continue to purchase.

Okay...

I have not seen any significant changes in my skin, I think other products work better and its unfortunate because of the high price point. I use a lot of other is clinical products that work effectively but not so much with this Vitamin C. It is a thin liquid that absorbs quickly into the skin. The smell is light and nonirritating.

Can’t believe how this has changed my skin for the better! Especially impressed with how it has made my pores smaller.

Works well…not my favorite

I religiously use iS Clinical’s Pro-Heal Advance serum, but opted to give this a shot due to the increased amount of Vitamin C. I think I still prefer Pro-Heal. I’m combination skin, acne, 46 years old. I’m just not wow’d by GeneXC…especially for the cost.

Awesome

Wow. This serum gave my skin such a healthy glow that I was absolutely impressed. It also seamlessly removed dead skin cells. It does not burn for a 20% L- Ascorbic Acid. It is very lightweight which I personally love, let's me know it has a greater chance of penetrating my pores and getting to where it needs to go. Expensive but hey, worth the sacrifice. A little discount from LovelySkin helps. This one is a must have in my book.

It’s nice

I have used this for a few weeks and it is nice but I’m not sure I’ve noticed much change in my skin.? One thing I have noticed is that is is sticky so definitely don’t use a lot. Because of that, I used it at night only. Not sure how it would layer under make up. Don’t think I would repurchase. There are other is clinical products such as the poly vitamin serum that I like better.

Amazing!

This is the first time I ordered this serum and I have been using it for about 2 weeks now. I love how it makes my skin so clear and smooth. I use it to set my face cream.

Great

This is a great serum. I use it at night, and it seems to work really well with my skin. Like other IS clinical serums, it’s as light as water, so doesn’t clog up my skin or feel greasy, but works so well! Great list of powerful ingredients.

iS Clinical Gene XC Serum

Using this product with iS Hydracool for morning skincare every other day for approx 4 months. (iS Active Serum /Hydracool used on alternate days.) Skin appears brighter/clearer/decreased oiliness. Forehead lines appear not as prominent. Would definitely recommend this product.
