Comments:

  • Easy to apply: creamy, smoothes on well, easy and fast to apply evenly. I’m applying as usual to dry skin after it’s been washed, dried, and moisturised.
  • Zero irritation 
  • Zero zits and/or irritated cloggy areas
  • Dries fast
  • But moisturising and non-drying
  • Better and nicer than their previous all-zinc sunscreens: they were either very siliconey-slippy, or powdery-dessicating, or both. This translates in BlurbSpeak to “silky soft,” a phrase that you’ll see in many an online review; its presence should alert you to a review probably being a pseudo-review that’s a more-or-less unsubtle copy-past job on advertorial bumff graciously provided by a marketeering department (or straight off the product label of the “Face” tinted SPF 40). But I digress.
  • Invisible finish but: on me; I am NW05 approximately and match walls; YMMV. CoTZ have a tinted face SPF 40 which is available in two shades, but it isn’t just ZnO it uses TiO2 too.
  • Slightly weird smell, rubbery? plasticky? for a brief moment when applied; disappears
  • Contains TEA: this irritates my eyes in anything other than minute concentration in mascara, but OK in a product like this one at low concentration.
  • The sunscreen filters are coated (that’s what most of the silicones and crosspolymers are doing in the ingredient list) and small, hence use of the term “transparent”; CoTZ uses several different particle sizes in their “Gentle Mineral Complex.” This is a very good approach to protection and the best compromise between smaller particles (= best coverage, least concentration needed, very elegant thin sunscreen, but The Nano Concerns for whatever that’s worth) and larger particles (= less coverage–more and bigger gaps between particles–and uneven coverage; a thicker layer with a higher concentration means inelegant clownface). 
  • Cheaper than comparably elegant ZnO-only face sunscreens, ex. Replenix sheer physical cream
  • Less greasy-feeling than Replenix sheer physical spray (which contains no grease, so go figure)
  • Spread more evenly and sinks in more smoothly than a non-silicone “greener” ZnO-only sunscreen like Derma E
  • Needs more serious attentive removal, like any other siliconey sunscreen: oil, or a good milk-fluid (La Roche-Posay Tolériane dermo-cleanser fluid works well, use a little more or clean twice or something similar, use common sense and good judgement to figure out when the stuff’s successfully off your tender visage)

  
The Pediatric SPF 40 is basically the same stuff and usually the same price. This is worth knowing as sometimes one will be available but not the other, or a website may sell out of the one or the other (the same tip applies to that great sunscreen classic, Blue Lizard, and its “Sensitive” and “Baby” versions):
