Reef Advantage Calcium is a gentle (pH 8.3–8.6) specially formulated blend of ionic calcium aimed at restoring and preserving calcium levels similar to those in natural seawater. Calcium and carbonates play a crucial role in coral growth. A deficiency in either can halt coral development and lead to a swift decline in coral vitality.

Additionally, Reef Advantage Calcium contains magnesium and strontium in ratios that reflect typical usage (100:5:0.1, Ca:Mg:Sr). This ensures that these vital elements are maintained along with calcium. Unlike limewater (kalkwasser), Reef Advantage Calcium does not have a harsh pH and will not reduce magnesium levels. When used as directed, it will not affect alkalinity.

Wow - my new favorites 💜👍😀
Scent: Retinol, Size: 17 Fl Oz (Pack of 1)
I just purchased this and tried it last night for the first time along with the firming version. I didn't take photos because I was skeptical as a product I had purchased from a different line for more money didn't work. This morning I notice that not only does my skin feel more hydrated but the texture appears more smooth. I recently turned 75 & lost my husband a few months ago and having been a care giver for awhile and put taking care of me aside. These products and body wash are great and I like the fragrance. Please give them a try. To have something show this much difference over night is incredible. They are also affordable which is a plus for me. Thank you Olay.

Love
The Dove body serums are amazing , I hope they never stop selling them. My skin feels and looks great since I’ve been using Dove beauty bars, cream serums and their body Deo. Great scents and great for my skin. This body serum is light has a very light floral scent and leaves my skin feeling great and like most Dove products at a great price. Time will tell if it helps to lighten dark spots, I’ll update my review in two weeks but for now… I love this stuff, my skin is super soft without heavy creams.

Gentle,hydrating,and helping even out my skin tone
I’ve been using this Dove Body Serum with niacinamide for just a few weeks, and I’m already noticing a visible improvement in my skin. During pregnancy, I developed some uneven skin tone and dark patches, and this has been helping my skin look more even and healthy. It feels lightweight, absorbs well, and keeps my skin soft and hydrated without feeling greasy. My skin already looks smoother and brighter, and I’m really happy with the results so far. Definitely a great body moisturizer if you’re looking for hydration plus gradual skin tone improvement.

Love love love!!
I LOVE this lotion. It's extremely lightweight, doesn't have a strong odor, and it's actually moisturizing! It's light enough to where I use it on my face as well and it doesn't feel greasy at all. No skin irritation or anything and I have sensitive skin. HIGHLY recommend.
