Absolutely Love It – Deep Hydration That Lasts!
Size: 8 Ounce (Pack of 1)
The Dove Body Cream Serum with Hyaluronic + Hydration has quickly become my go-to for tackling extra dry, flaky skin — and I absolutely love it!
💧 Deep, Lasting Hydration: From the first use, my skin felt instantly hydrated — and what’s even better? That hydration actually lasts throughout the day. No more reapplying!
🧴 Lightweight & Non-Sticky: It goes on smoothly, absorbs quickly, and doesn’t leave that greasy or sticky feeling — just soft, nourished skin.
🌿 Skin-Loving Ingredients: With pro-ceramides, niacinamide, and collagen peptides, it feels more like a high-end skincare product than a typical lotion. My skin looks visibly healthier, more even-toned, and has a soft glow.
✨ Bonus: It’s gentle enough for daily use and has a clean, fresh scent that’s not overpowering.
If you’re dealing with extra dry or flaky skin and want something that works and feels luxurious, this is it. Dove nailed it with this one — hydration, comfort, and glow in one bottle.

Soft Skin All Day Without That Greasy Feel
Size: 8 Ounce (Pack of 1), Size: 8 Ounce (Pack of 1)
My skin is dry and tends to get ashy, and after showering it can look worse, especially on my hands, elbows, knees, and heels.
I apply this while my skin is still slightly damp. It goes on creamy but absorbs quickly, so I don’t get that greasy or sticky feeling some lotions or body creams leave behind. I can get dressed right away without waiting.
It keeps my skin looking and feeling hydrated all day without needing to reapply.
The scent is light and clean, nothing strong or overpowering.
If your skin is severely dry or cracked, you may need something thicker. For my dryness, this does the job. It’s the one bottle I reach for every day.

Disliked at first, ended up LOVING!
Size: 8 Ounce (Pack of 1)
UPDATE: I actually ended up loving this product once I started treating it as a first layer serum. I use a very small amount, let it soak in for a minute or two, and then layer a body lotion over it. Using it that way gives me the softest skim (even on rough dry areas like elbows) and it totally takes away any sticky/tacky feeling!
I don’t quite know how to feel about this product. It is hands down one of the most hydrating body lotions around and immediately after application skin does feel silky and smooth. It causes no irritation and has almost no scent. However the longer it is on the more tacky and sticky it gets- even dabbing extra off with a towel does not help. It is particularly bad on the hands, I literally could not stand it because it felt like I had partially dried glue all over my hands. Strangely the one place this lotion works on is my feet and it really helps with any dryness (I’m an avid walker and hiker so my feet get dry). I would not purchase again because I can’t use it anywhere else. I wish it stayed feeling like it does immediately after application because I bet it would help skin look and feel smoother with continued use, but unless the formula changes to something that isn’t tacky and sticky it is basically worthless. Unless you want to purchase as a foot cream!
