Super Serum Advance+, Anti-Aging Vitamin C Face Serum, reduces scaring and fine stretch marks

If you have acne prone skin, hormonal and or adult acne and have tried other LAA serums with no hope, you need to try this serum. This is the only LAA that my skin will tolerate without causing acne or deep bumps underneath my jawlines. If anything, I believe this has help manage my acne due to the zinc property along with the other soothing ingredients. This does not burn, it dries to a matte finish. Though, I would prefer a glow finish. It has a slight distinct smell but doesn't bother me. It has significantly brighten my dark spots within days! If I have have future dark spots, I know this serum will take care of it. It has ZERO pore clogging ingredients and I would consider this to be gentle on the skin.

Love this product!

It might be a tad expensive, but it has done wonders for my skin to even it out and make it so smooth. Lines seem to have almost vanished (I'm 57). I have sensetive skin and this was not harsh, nor did it break out my skin. VERY happy with this product and would recommend this to anyone with sensetive skin who wants their skin to feel soft and look radiant. I get SO many compliments on my skin. Have been using for 5 months and will continue to do so.

This super serum is the best of the IS clinical line, imo. it's the only one without alcohol, which is good "because alcohol dries your face out and makes you look older" ;) but seriously, the ingredients are quality, moisturizing, and brightening if your skin can handle vit c.. at first, my skin needed time to adjust to it (a couple of days). Either way, it has brightened my skin and faded red marks relatively quickly (within a couple weeks). Just please, beware of your supplier. I would avoid products sold by PSYDUCKONLINE. I've bought from this distributor a few times and I do not trust them. They watered down the samples I bought from them a couple years back.

First of all I have LOVE this product when I get from my dermatologist. My Dermatolgist rain out so thought I would try Amazon! I’m returning this product because it appears to be diluted. It should be yellow and a bit thicker and is clear like water. This can’t be the product (unless they completely changed the product and smell) and I am deeply concerned on what I just put on my face! I am taking pictures before I return as this is not the real product which is not cheap! Would LOVE for the seller to contact me.

To be clear - the serum itself rates five stars. It's positive effects are well described in the other customer reviews. I might add that it gives me a bit of a very attractive tan after a few hours. I'm giving it 3 stars because of the packaging. The small glass bottle is tall, and after getting the eye dropper into the very small opening the bottle is very easily tipped over. If you don't use the eyedropper and just tip a few drops into the palm of one hand, it is, again, easily tipped over as you place the narrow, top-heavy bottle back on the counter/sink. I have tipped these bottles over at least three or four times and spilled out $30, $40? worth of product each time. Years ago they sold a two-ounce bottle with a pump/spray cap, which was far easier to use and never spilled. I saved the spray bottle and refill it (halfway) with the one once bottle. Unfortunately, even this is tricky as I must use a funnel to pour from one tiny opening to the other and the product foams up (like a shaken can of soda) during this process and the foam pushes up and out and I lose several more dollars worth of product. Very annoying and ridiculous for an item that sells at over $100 per ounce. At the price, the least the manufacturer could do would be to make all size bottles with a pump/spray top.

Too soon to tell results; the serum claims to help skin both firmness and color fading (scars); imagine it will take time.

I have used this Vitamin C for years now and I think it’s amazing.

My aesthetician recommended this product and I have been using it for a year! It has been my holy grail ever since I started using it! Of course it also help with good facial treatments, microneedling and chemical peeling my acne scar is clearing. Just trust the process of selfcare ❤️ use this as your daily facial routine it is the best!

El producto venía abierto y usado, solocite la devolución el mismo día que lo recibí y regresé el suero y aún no me han hecho la devolución

So far so good

Used it a week so far and my skin feels firm and less wrinkly, definitely a brighter complexion and my acne scars are starting to fade. It hydrates without making your face look greasy or oily. Will defo buy again. Great price compared to other clinical based products out there.

Meine Kosmetiker hat mir die Produkte von iS Clinical empfohlen und ich bin mega happy. Benutze 3 Produkte aus der Serie und meine Haut sieht beruhigter aus und die Poren feiner. Keine Reaktion oder ähnliches. Meine haut musste sich auch nicht dran gewöhnen. Habe das Serum schon einige male verschenkt. Alle sind zufrieden und glücklich
