iS Clinical Active Serum

I have been using this serum and Youth Complex cream for a week now. I use it only at night. The result is impressive, fine wrinkles and pimples are gone. In the morning, when you wash your face, your skin is smooth, if you compare, you can see the improvement.

I use it at night, 15 minutes after application, my face becomes porcelain, facial wrinkles disappear, pores narrow, I like it overall

Awesome serum

I love this serum
it really helps keep my acne at bay and is not too strong best serum ever

This product is excellent. Makes your face feel good and look bright.

I have been using this serum for years after being told it would help with cystic acne. Once I started using it, I never dealt with cystic acne again. I have used it throughout my pregnancies and breast feeding journeys. I use it at night along with their emulsion cream, and I use the pro heal serum in the morning. I love it! It’s gentle but effective! Worth every penny.

This is one of the best skincare products that I've ever used. It keeps my skin clear of blemishes and has anti-aging benefits. Love it!

Can’t live without this serum. You can feel it working the second you put it in and my skin drinks it up.

Absolutely phenomenal! My esthetician recommended this serum about 3 years ago and this has been my holy grail since. Nothing works as good! 10/10

Wish knew about this serum when I was 18, but sure glad my esthetician introduced me to it now. Effectively pushes out the junk and clearing up my skin.

It solves the acne problem - unexpected. Also, it has other effects like removing some acne scars and the fine lines. it makes the skin glow and you get a very fresh skin in just 2 weeks.

So effective, nice result just after couple times using

This product is extremely effective in clearing cystic acne, clogged pores, blackheads and bumpy skin. I've used scores of products to heal issues and this one works quickly and as described. It leads the pack.

Active serum has saved my skin. My pores will get congested very easily and this serum helps keep my skin clear. It’s not easy have aging and blemish prone skin but active serum truly works. It’s a must have in my routine.

The best! I've tried a million products, only this one works instantly. Reduces inflammation, evens out the tone. And if you suddenly "goofed up" with a rash - it eliminates the consequences overnight. Not a serum, but great love.

I buy this over and over again. Use it morning and night before the reparative emulsion. My skin loves it. Never want to be without!

I have used 2 other is clinical serums and I like this one best for the morning. It has a cool feel and helps wake your face up

I love this product so much. Ive tried others to replace it and you cant.

I use it at night, 15 minutes after application, my face becomes porcelain, expression wrinkles disappear, pores become narrower, overall I like it

I bought this in combo with the warming honey cleanser and I am obsessed with how clear my skin has been. I typically have large pores and very oily skin, and since using these products together, my pores have shrunk and my skin is significantly less oily. I only use the serum at night, as instructed, and a little goes a long way! The price is worth it considering how long it lasts!

This serum is pricey but it is so worth it! It is the only serum I have ever used that truly works for me. It definitely has helped with my acne and it has made my skin smoother and more refreshed. I also love the slight tingling feeling it gives. Overall great product and I always recommend it to my friends.

Love the product, I can tell my overall skin texture is smoother and brighter.

This serum really works to control acne and correct uneven skin tone. I have used it for 3 weeks now and already see a material difference.

Active Serum by iS Clinical

The iS Clinical Active Serum is a highly effective product.

This skincare product is truly one of the best I have ever used. What I love most about it is that you only need a small amount to effectively treat acne, and it clears it up quickly. It doesn't dry out your skin, and a few drops go a long way. It also delivers on its other claims for improving your skin, but personally, I appreciate it for preventing occasional acne breakouts. And if one does appear, it stops it in its tracks. I highly recommend this product, although I do wish it wasn't so expensive.

No acne breakouts. Can be applied multiple times a day due to its gentle moisturizing formula. I appreciate that it is not excessively thick or oily, as it feels light and refreshing on the face. The only downside is the cover design, which can be inconvenient when opening and closing the product.

I have been using Vital C products for almost 5 years and have not experienced any breakouts since I started using them.

For years, I have been using this product on the recommendation of my Esthetician, along with other IS Clinical products. Together, these products have improved the texture and elasticity of my skin, especially when used in conjunction with regular facials.

This product is amazing for treating acne. It has a strong and effective formula that you can feel working on your skin. I highly recommend it and it's definitely my favorite product from this line.

I have used this product for an extended period of time.
