IS Clinical is the holy grail!

I have used the IS Clinical Active Serum for almost 20 years and wanted to add this to help with uneven skin tone and dark spots as I approach my late 40s. Wow! Within a week a few of the spots were noticeably lighter, and barely a month later they have almost disappeared. I use this at night and the active serum in the morning, IS Clinical Cleansing Complex twice a day, and the IS Clinical Moisturizing Complex twice a day. Yes, these are pricey, but you don't need to use a lot of product, so the bottles will last a while. And they WORK!!! You get what you pay for.

Fantastic vitamin C product

I have repeatedly ordered iS CLINICAL Super Serum Advance+ because it has proven to provide a noticeable brightening to my skin. I stopped using it consistently a few months ago because I was trying to integrate different products into my routine, but came back to using it and saw almost immediate brightening soon after. For me, this is a holy grail product, and I would recommend it to anyone wanting to brighten and give their skin a glow.

Love it

Those product gives me a nice glow and helps keep my moisturized all day. I have sensitive skin, but this does not bother me and seems to be effective.

Brighter, Firmer, and Youthful Skin

I absolutely love the iS CLINICAL Super Serum Advance+! It has transformed my skin—fine lines and uneven texture are visibly improved, and my complexion looks brighter and more radiant. The serum absorbs quickly and feels lightweight, yet delivers powerful anti-aging benefits. My skin feels firmer, smoother, and healthier after regular use. Highly recommend for anyone looking to target signs of aging and boost overall skin radiance.

The best vitamin C serum for me!

I have been using this vitamin C serum for at least a few years, if not more, now. This was the first VC serum my skin did not react badly, and I also like the way it brightens my skin. I try buying it on sale and having a stock enough to last for at least several months.

Very Nice!

I usually use iS Clinical Healing Serum so I thought I'd try this for a change. I like it and would buy again.

More than just a Vit C Serum

I’ve never stayed faithful to a single vitamin C serum, even THAT famous one. I was about to give up on them completely, thinking my skin simply didn’t respond as well as others to the vitamin’s brightening effects. However, the ingredient list on this Super Advanced Plus serum is just so impressive! More skin brightening ingredients than any other brand, and a blend peptides to boot. So far, I have seen a gradual brightening of sun damage and an overall boost in radiance. I expect to see more results with continued use. So happy to have easy access to the serum at a great price here on LovelySkin.

My Face Is Brighter

I have tried many products in my search for the perfect anti-aging skin care. Lots of broken promises from high and moderately priced serums, potions and lotions. I've been using this Super Serum Advance + for about 3 weeks and I do believe my skin looks brighter and more even toned that before. Many years ago I was a sun worshipper and though it felt so good back then, those age spots and uneven skin tone are not easy to reverse. Once daily use of this serum at night, under a very emollient hydrating cream has really made a difference in just a few weeks. I tried using in in the morning under makeup but it definitely pills for me. So even just using it once a day has shown some improvement for me, and I'm hopeful that as I keep using it, my skin will look even better! This is not an inexpensive product but it looks like it will last at least 3-4 months if I use it once a day so I feel the cost is worth it if it makes my skin look bright and even! Try it yourself and see!

So far so good

Smells neutral. Goes on easily. No irritation. Haven't used long enough, so still waiting to see results.

Nah

This irritated my skin and caused breakouts for me. I do have acne prone skin though so I still think it’s worth trying. Texture and application was nice.

Is Clinical Super Serum Advanced

I’ve been using the super serum advanced for a few years now and have been very pleased with the results. I don’t have to worry about dark spots from sun exposure (and I spend a lot of time in the sun). This was recommended for me by the esthetician at my dermatologist’s office.

Alternative to the other brand

So far I am really loving it! I notice a slight stinging to my face vs the other major name brand that starts with an S. This tells me it is more concentrated. Also like that it helps with collagen synthesis and has other actives. My skin is brighter for sure. Still halfway on my first bottle. Will probably re-order.

My holy grail serum!

I have repurchased this serum over and over and over again! My previous esthetician used it on me and recommended it and I have been hooked since! I truly notice a difference when I run out! Will forever rebuy!!

Superior Vitamin C serum

I’ve tried several vitamin C serums including the Pro Heal, and this has been the best one by far. I have sensitive, acne prone, combination skin, and this serum did not cause any adverse reactions as other vitamin c serums have. After one month of use, I can see lightening of my hyperpigmentation and overall brightening of my skin. I took away one star because the product does sting when first applied to my skin, but it dissipates quickly.

Nice Serum but super thin.

I think I am seeing results after using it for about a month. I do not have bad issues with my skin and have used several of their products. It is super thin so you have to be careful when applying it.

Good serum

I was between this and the Pro-heal that I normally purchase. This was good but next time I'll good back to the Pro-heal because it keeps my skin a little more clear.

The best vitamin C serum

Saw wonderful reviews about this product so I decided to pick it up during the holiday sale.. my favorite new vitamin C serum. The texture is very thin and absorbs right into my skin. Not to mention the copper peptides/other beneficial skin ingredients. Definitely a winner. I picked up the smaller size because I wasn't sure how my skin would react to it as I have very sensitive skin but this is product is so gentle.. will pick up the larger size when I'm finished. Also like the dropper on this product, makes it easy to use.
