Smooth, plump skin with minimal pilling and great value\.
[I received this product in exchange for my honest review] I've been using Kiehl's CollaShot Plumping Serum consistently for 30 days, which gave me enough time to evaluate how it performed as part of my regular skincare routine. Overall, I was impressed with the lightweight feel, hydration, and grad...

✨ 🤏☕ When the Marketing Plumps More Than the Product ✨
[I received this product in exchange for my honest review] TL;DR (for busy shoppers) • Texture: lightweight bouncy pink gel-serum • Performance: immediate hydration, subtle long-term results so far • Standout: gives skin a healthy, dewy appearance • Best for: shoppers wanting hydration and g...

Simple and it works!
[I received this product in exchange for my honest review] I've been keeping my skincare routine VERY minimal this summer — wash my face, multi-peptide serum, this, moisturizer. That's basically it. And somehow my skin has been looking better than it has in a while 😂 I've genuinely loved adding the Kiehl's CollaShot Plump Serum into the mix. It's this really pretty pink serum, feels cool and super smooth going on, and I LOVE the fresh scent. It's also one of those products that actually makes my skin look plumper and just… better? without adding a million extra steps to my routine. Simple skincare girl summer, apparently. 💗

For me it's a no.
[I received this product in exchange for my honest review] I used this product for a few weeks with just basic skincare (cleansing, toner, moisturizer). I did not see a change in my skin. Like many skincare products there is a fragrance but it's not strong. This is not a product that I would purchase.




Great product!
[I received this product in exchange for my honest review] Loveeeeee this product!!!!!! It smells so good! It's very lightweight and not sticky! I love that's it's in an easy pump and it's travel sized! Definitely recommend!


Lightweight daily skincare staple!
[I received this product in exchange for my honest review] Love this serum! Using in the morning and evening consistently, I have seen noticeable improvement in my overall skin hydration and plumpness. The gel-like formula is light and easily absorbed, and layers well with other products as well as makeup. Will definitely be refilling!
