Features and Benefits

Refreshing, Rebalancing, and Hydrating Facial Mist to Nourish the Skin Throughout the Day.

A lightweight, oil-free moisturizing face spray that restores hydration, balance, and freshness to the entire face with just a couple of spritzes. This face mist spray goes on like a sheer veil and features pure Icelandic water filtered through volcanic lava rich in minerals, Hyaluronic Acid, and OSA (Orthosilicic Acid) a natural, geothermal silica extracted from high-temperature geothermal steam in Iceland. Rejuvenate and refresh skin while minimizing signs of dryness, dullness, and fatigue without any oily or greasy finish. This is an essential beauty water mist for frequent travelers, commuters, and people who work in environments with dry, recirculated air.

Use as often as needed throughout the day. Also recommended to mist on clean skin after BIOEFFECT Micellar Cleansing Water before applying any BIOEFFECT serums as the EGF protein performs best in a moisture-rich environment.

Why OSA (Orthosilicic Acid) & Hyaluronic Acid?

Silica is a common trace element found in our bodies and has been associated with bone and skin health, especially as it relates to healthy collagen and elastin production. OSA (Orthosilicic Acid), is a rare, natural form of silica which the skin can absorb and utilize. Our OSA is extracted from high-temperature geothermal steam here in Iceland. The mist also includes optimized Hyaluronic Acid, with a low molecular weight to ensure deeper absorption, for deep hydration. Together they keep the skin hydrated and looking firm, healthy, and plump.

Key Ingredients

Hyaluronic Acid – A vital substance naturally found in skin. It is critical for maintaining skin hydration. Known for its incredible capacity to attract and hold vast amounts of moisture. Hydrates and plumps the skin.

OSA (Orthosilicic Acid) – A natural bioavailable form of silica that the skin can absorb, helps support skin’s structural integrity, helping it stay looking firm, plump, and taut. Quite rare in nature but can be found in high-temperature geothermal steam in Iceland.

Icelandic Water – Clean, soft, and pure, as it is geologically filtered through layers of inert volcanic lava, with a low concentration of hard minerals such as calcium and magnesium.

I am new to this line and have to say the products are phenomenal. I had my barrier compromised trying new products. These products repaired my issue within 3 days. My only complaint so far is with the sprayer on the mist. It worked for the first week now it doesn't spray it just leaks out. Is there a way to fix this?

Amazing water and THE BEST PACKAGING

I use this water after the serum. I find that absorption of the serum is even better if I use it after not before, because it has ability to penetrate even though the makeup, so I feel like it is pushing serum to deeper layers of my skin. That's my experience. I also love, love, love the packaging!! Ladies, this is the best possible packaging for the mist, it's so convenient for the travelers, for the purses etc. Unfortunately, so many glass bottles were broken in my suitcase (and even on my bathroom floor, ah, pets and children!) that I really appreciate so brilliant and lightweight packaging. Please don't change this fantastic packaging, so easy to carry everywhere! And try this as a makeup's refresher, you would be delighted with the results.

Bottom line: Yes, I would recommend this to a friend

I take the OSA water mist with me everywhere, always in my purse. Its great for traveling and after a long work day. It "wakes up" your skin and leaves it feeling refreshed.

Love the Product, but Dislike the Packaging!

Five stars for the water ... so hydrating and perfect prep for the serums. It works well on top of makeup to refresh throughout the day too. But, I have a bone to pick with the packaging (hence the four stars). Watch out! It's more of a jet spray than a gentle mist. Also, while convenient for travel, I'm not a big fan of the opaque plastic tube. My solution ... bought an empty glass mister bottle, sanitized it, cut open the bottom corner of the tube and pour it into my empty bottle. Now it's perfect ... finer mist, clear bottle to see when I'm getting low, and it's easier to store. Just hope I didn't contaminate the water. 🤦🏻‍♀️ So, BIOEFFECT, please consider upgrading the packaging!

Bottom line: Yes, I would recommend this to a friend

Always in my purse

I always keep the OSA water mist in my purse and use it on the go, in the office and when I am travelling. I also use it before I put on my EGF Serum, I find it´s a really good base. It´s a must have if you work in a dry environment or travel a lot.

Bottom line: Yes, I would recommend this to a friend
