I have been in the beauty industry for over 6 years, and I have never tried a unique product like this one. It is a vegan spray that contains probiotics! Being a nutrition professional myself, I am aware of the benefits of probiotics when they are consumed, so I am amazed at the benefits of when it is applied on the skin. It also contains amazing ingredients like vegan collagen, peptides and hyaluronic acid. It helps with firming, lifting and plumping the skin and hydrates. I love that is also helps with the signs of aging and stress while also nourishing and supporting the skins pH. My favorite way to use this is after cleansing my skin, both morning and night time. It feels like my skin drank a glass of water. I also feel like it helps the rest of my products absorb better. My skin loves this product! It also doesn't irritate my skin at all. I plan on continuing to use this product regularly when I run out. This has quickly become one of my "must have" products.

A new spin on serum - spray serum! Kosas Plump & Juicy Spray-On Serum is a unique vegan spray full of collagen, peptides, and plant-based probiotics. This is an oil-free hydrating, anti-aging serum safe for most skin types, including sensitive skin. The glass bottle is gorgeous and makes a statement on my product shelf. Kosas Plump & Juicy Spray-On Serum has a light floral scent and leaves my skin feeling hydrated and plump. Over my 20-plus years as a medical esthetician, this would be the first spray serum that I have reviewed and I am here for it. Applying the spray serum can be tricky if you have false lashes and this would be my only con. I recommend spraying the serum on a cotton round to apply near the lash area. I also went a few steps further and sprayed this serum on my neck and decollete......AND...drumroll...I LOVED to apply a tiny bit on top of my makeup.

This is a next level serum that I really appreciated having in my skincare repertoire. I love the fact that it's an easy spray on product that contains collagen and helps protect the skin by introducing probiotics. The fact alone that you spray and go was a big win for me with this product. It was much easier to use than traditional serums. I felt like it hydrated my skin very well and as someone who has been in the business of cosmetology and selling skincare and makeup for 9 years this product really impressed me with its ease of use, hydration and I was even able to use it on other parts of my body as well. I love how much product you get (it's a big bottle!) And I love the color and the fact that it was unscented. I'd definitely keep this in my collection !

As a licensed cosmetologist and educator for many years, skincare and hydration are a few of my top concerns. I have used a couple Kosas products in the past so needless to say I was down to try this. I really like the Kosas Plump & Juicy Spray-On Serum. This spray-on serum is vegan and contains collagen + probiotics. It also can be used day or night and works with all skin types. It's lightweight, unscented and quickly absorbs into your skin. After four weeks, I noticed that my skin is more hydrated and visibly firm. On average I used it about 2-3 times per day and most days I did not wear makeup. If you struggle with loss of plumpness and dehydration like myself, this is the go to for that as well. Being a lover of clean beauty products as well as one that lives for the natural girl next door look, these type of products make my day. I would definitely recommend giving it a try.

Kosas Plump & Juicy Spray-On Serum! What worked? I loved the glass bottle and the weightedness of the bottle. Kosas paid attention to the type of spray that left a lovely experience. I did not feel attacked by the spray, and the nozzle never clogged. The spritz from the bottle stayed consistent, and I love that they used a spray vs. a dropper. I feel I often waste product when it drips down my hand or between my fingertips when using a dropper. The spray is a fantastic addition. I noticed overall hydration on my skin, and I loved that since it came in a spray, I could easily spray dry areas on my body before applying a body lotion. I loved it for my legs. Did I notice any firming properties? No. I also didn't notice any lifting properties. If I had noticed these two changes, I might feel more comfortable with a $48.00 price point. When I think of Kosas, I think of some interesting, fun, forward-thinking items, and this falls into that and feels very on-brand. My only caveat is that I am not sure I saw enough of the claims for me to pay the asking price. I liked this item so I looked up the price to consider purchasing and adding it to my repertoire, but I think it may be a bit high (for me) for the benefits that I experienced.
