Powerful Strength Line Reducing Concentrate - Siero viso antirughe

Bright, smooth, and powerful — a must-have Vitamin

This serum has a smooth texture and absorbs quickly without leaving any stickiness. The scent is fresh with a slight citrus note, very uplifting in the morning. I like the packaging, the pump keeps it clean and easy to use. In terms of effectiveness, it really brightens my skin and makes it look more even after a few days. You can slightly feel the warmth when applying, which shows the Vitamin C is active — love that!

Wanted to love

Feels wonderful going on but made my skin break out so no idea if it actually works

Attention

Ce produit m'a brulé la.peau du front en 2 utilisations. Je n' ai pourtant pas du tout une peau fragile. Plutôt à tendance grasse, depuis son utilisation je suis avec une peau extra sèche et des démangeaisons c est horrible

Love it!

This is my first time trying a Vitamin C serum, and it didn’t irritate my skin. It has such a soft texture, is easy to apply, and has a nice scent.

Using it for years. Replenished for the fourth time now. It makes a big difference. Stopped using it for a few months and just started again. Face is glowing and complexion is just much better. One of the few staples I carry

Triggers Pimple Breakout EveryTime.

I love Kheils products BUT the Vitamin C Serum makes me break out with pimples every time I use it. I don’t have a breakout or pimple problem generally and have gone stretches without using the serum to see if in fact the serum is the trigger. And unfortunately it is. Every time I use it I am assured to wake up with pimple. Bummer.

Great Product

Results from this product are very gratifying. I purchased to minimize fine lines and dark spots. The forehead lines? I’m very pleased they are disappearing after 2 weeks of using 2x/day. The dark spots may take a little more time. Overall a great product for my use, I’m also experiencing some slight firming in my problem area (forehead). We’ll repost more results after a month. I’m Happy I purchased this product

Love the hydration!

A delightful serum that hydrates and smoothes my skin. My skin looks better and I have used it for several years. Of course, drinking water always helps too!

Reformulated, unfortunately

I have been using this serum for several years. It was recently updated and appears white instead of the usual yellowish color. Also, the tingling sensation is gone. Wish the ingredients would have remained the same.

Fast-absorbing Vitamin C serum that brightens, smo

The Kiehl’s Powerful-Strength Vitamin C Serum has been amazing for my skin! The texture is silky and smooth, and it absorbs quickly without feeling greasy or sticky. I love that it layers well under moisturizer and makeup. It has a light citrus scent that feels fresh but not overpowering. The packaging is practical with the pump, which makes it easy to control the right amount of product and keeps it hygienic. In terms of effectiveness, my skin looks brighter, smoother, and more even-toned after consistent use. Fine lines are less noticeable, and it gives my skin a healthy glow. Definitely a staple in my skincare routine!

Part of my morning routine

I am not a fan of putting too many products on my face especially in the morning when there’s just so many other things to do. I limit it to 4-5 products and this has to be part of that routine!

Made my face look orange

I have light skin and this did nothing but turn my skin orange. I was not wearing any makeup at all and my husband said I looked tan. I wiped my face with a makeup cloth and you can see the orange/pink streaks from this lotion in the photo.
