This has to be the absolute best face SPF I have ever tried. I live in Australia and the ozone layer here is quite thin so sun protection is a big issue to get right. I have gone through the gamut of face SPFs and hated most of them (actually all except for this one). La Roche Posay, Neutrogena, ego, Dermalogica, La Mer, Chantecaille, Aesop face spf, Cetaphil Suntivity, Mecca brand, Clinique... and the list goes on... all not meeting up to their hype - too greasy, white cast, strong odour, not great under make up, irritating the eyes and skin, break outs, makes me look orange (yes, that's right, orange!)... you get the picture.
The Zelens Daily Defence Sunscreen is a ripper of a product. Invisible, clean feeling and doesn't irritate at all. It has a bit of a pronounced fragrance on application but dissipates after a couple of minutes. My face feels hydrated and not sticky in the slightest. It's a great makeup base but I tend to not need to much of anything else on top as it makes my skin look rather nice on it's own.
It also washes off well, which is another problem with other SPF's I've tried. They tend to build up over time and cause further breakouts, but this Zelens one doesn't do that.
It may not seem as 'lightweight' as you might first think but it's not overly heavy either and it smears over the face like a nice moisturiser. The final feeling is velvety-smooth.
I also like the fact that it's designed by a leading plastic surgeon. If most damage and aging to the skin is the result of sun exposure then I doubt we'd find anyone better to trust when it comes to creating the best shield for our skin. Really worth the money. I'll keep looking into other options from time to time but I highly doubt I'll find a better product.
