    Physical Fusion UV Defense SPF 50


    Physical Fusion UV Defense SPF 50

    Broad-spectrum UVA/UVB sunscreen fluid to enhance natural skin tone

    Physical Fusion UV Defense SPF 50 is a weightless fluid with 100% physical filters that effectively provides broad spectrum UVA/UVB protection and is water resistant up to 40 minutes.  This high protection zinc oxide sunscreen contains artemia salina, a plankton extract that increases skin’s resistance to UV- and heat-induced stress, and translucent color spheres that adapt to every skin tone for an even tone, radiant finish. 

    *Z-COTE HP-1 is a Registered Trademark of BASF
    **based on in-vitro testing

    Formulated with transparent Zinc Oxide (Z-Cote®), the only physical UV filter spanning the full UVA/UVB spectrum, and translucent color spheres that adapt to all skin tones. This ground-breaking weightless tinted sunscreen technology provides 100% physical broad spectrum UVA/UVB protection as it boosts skin radiance.

    Innovation 1

    Featuring a breakthrough broad spectrum technology, iron oxide spheres evenly disperse within fluid texture to provide sheer surface coating, UV protection, and universal radiance. Using a “Shake then apply” action helps ensure even distribution of sunscreen ingredients.


    Shake well before use. Apply sunscreen liberally to the face, neck, and chest 15 minutes before sun exposure and before applying makeup. Reapply sunscreen after 40 minutes of swimming, sweating, immediately after towel drying, and at least every two hours. 

    Sun Protection Measures: Spending time in the sun increases your risk of skin cancer and early skin aging. To decrease this risk, regularly use a sunscreen with a Broad-Spectrum SPF value of 15 or higher paired with a SkinCeuticals Vitamin C Serum.

    Artemia salina: This plankton extract helps boost skin’s natural defenses and resistance to UV- and heat-induced stress. (based on in-vitro testing)

    Key Ingredient 4

    So lightweight!


    I was worried about putting this on my daily face lotion because I hate thick caked on feeling. This lotion is so lightweight it feels like I'm rubbing a light powder over my face. It is fantastic! And the tint is perfect! I will definitely buy it again.

    Couldn't Be Better


    I've had a love/hate affair with most sunscreens--although I definitely need the protection (thus the love part), I hated that they mostly clogged my pores and left a strange filmy feel on my face. I first tried the first very light-weight SkinCeutical sunscreen and was very happy with it. But this one, with the tint, is exceptional. It feels wonderfully light on the skin but it has a little bit of coverage that actually makes your skin look prettier, AND has the blocking effect from those damaging sun rays. I couldn't be happier!

    Exceeds my expectations.


    I love this stuff. It helps even out my skin tone and protects me from the sun all without leaving my skin shiny which other products tend to do. In fact I spent all day in the sun yesterday and it was hot. I had put this stuff on in the morning and never re-applied (because I'm lazy) and I never got sunburned.

    Great for sensitive skin!


    I've been using this pretty much everyday without irritation or breakouts and the dryness issue doesn't bother me if I wear lotion underneath. I've noticed that when I'm out in the sun that my freckles and sun spots aren't darker at the end of the day like most sunscreens. This makes me pretty confident in it's UVA protection. I just ordered another bottle.

    Nothing like it


    This is the most lightweight sunscreen that I have ever used and probably so of any sunscreen currently in the market. (I am out of the sun most of the day, so I cannot comment on its sun shielding properties but it has held up well in the heat and humidness of D.C. weather and has not run.) It is watery and not heavy or creamy @ all and very similar to the consistency of 'fluid chemical sunscreens' sold by high end makeup lines that I have since discontinued using. The universal tint does not make my light to light/medium olive-yellow skintone look 'pink / ashy / white' in any way, as I have a very hard to match skintone. It is very sheer and will help even your skin but you will still need to use a concealer if you have any trouble spots. I also have very oily and acne prone skin and it does not worsen any of these conditions (this isn't listed as oil-free but it is non-comedogenic). A dusting of powder after I apply this solves any 'dewiness' it may leave. And what I love most about this sunscreen is, is that it really helps set and prolong the look and texture of my makeup once set w/powder foundation; not even primer could do that for my oily skin. Before I found this, using blotting papers throughout the day and just in general, my makeup would become a blotchy mess within a few hours. I was looking for a great lightweight and non-greasy tinted moisturizer (they all ended up being way too heavy / creamy) but found this instead (I use this w/a light application of powder foundation and an oil-free moisturizer underneath). It has saved me a lot of time and disappointment from trying another product that does not work. Do not hesitate to purchase this.
