New formulation is not what it used to be
I’ve been using this for several years now. I have recommended it to many people in the past. Just got a new bottle and was surprised to note a strong fragrance change. After using it for a couple of weeks, I realized the fragrance isn’t the only thing that’s different. The new formula doesn’t feel nearly as hydrating. I feel like I need to use twice as much to get the same result. I’m so disappointed, as this was a cornerstone of my skin routine for a long time.

Highly dissappinted with formula change
So disappointed with the fragrance/formula change! I’ve loved this product for maybe 2 years now and it’s been the only product to consistently work for my skin that long. The new fragrance is horrible, the old one was perfectly light and refreshing. It also doesn’t feel like it keeps my skin ‘glowy’ as long as it use to.

Terrible formula change!!
Terribly disappointed that they changed the formula! I’ve been using this serum for over a year and loved it for its hydrating and smoothing/plumping qualities. But the new formula makes my skin appear dull and dehydrated. It also smells awful! Will not repurchase unless they go back to the original.

Real Hydration!!
This serum is incredibly hydrating! Very noticeable skin plumping from hydration even with first use. You don’t need very much at all, a little goes a long way! 🙌

Terrible fragrance addition!
Been using and loving this serum for years. Just opened a new bottle and was smacked in the face with a dreadful, horrible, cologne smell. It is truly awful…Why…WHY did you ruin it?! *Cries*

It’s an Acne prone Sensitive skin best friend 🥰
From the packaging to the dispenser and the texture?…. That’s a full A plus. My skin will immediately tell me if a product is not good for me. I have Acne prone Sensitive, read that again and tell me if you would not live by a product that NEVER breaks you out. It immediately cools my skin and gives it a more plump. It’s in my skincare and makeup routine. You can take my money, Laroche Posay 😃. Don’t walk, run and get it 🌹🥰.

New formula made my skin red and burn
I have used the previous formula for a long time and I loved it. The change of formula was not good. It instantly made my skin red and it was burning. I had to wash it. I will not longer be able to purchase it.

Good day to day firming use
I like the product, it doesn't make the skin feel tight but appearance wise works well on the daily basis. I love the smell.

Remove fragrance!!
I thought I ordered the wrong product when I opened my newest bottle. I had to come back and check it was the same item. The fragrance is way too much, please remove. I am all fragrance free and now I can’t use this item.

Can we get a fragrance free option?
I don't have sensitive skin and the fragrance was too much for me. Everything in my routine is gentle and nourishing since I have dry acne prone skin. Wanted to give it a fair chance, so I tried this out for months, always applied on clean and damp skin before moisturizing, and it still burned a little due to the fragrance. Hyaluronic acid is such a great ingredient but this product is overpriced for what it is and too much fragrance.
