Smashbox Foundation Review: Studio Skin 15 Hour Wear Hydrating Foundation Review

This is the second part to my weekly series of foundation reviews; today’s blog post is everything you need to know about the Smashbox Studio Skin 15 Hour Wear Hydrating Foundation, which now has an improved formula that claims to last for 24 hours, so of course I needed to try this.

Smashbox cosmetics is a cruelty free brand that provides picture perfect makeup– the kind you want to use for that perfect Instagram selfie, it’s no wonder Smashbox was founded by photographer, Davis Factor who required makeup that looked perfect on camera and lasted through long hours of demanding shoots and studio lighting and viola – a 15 hour foundation was created – the Smashbox Studio Skin Foundation.

Here is my Smashbox Studio Skin Foundation Review:

Smashbox Studio Skin Foundation Review


  • Provides medium to full, buildable coverage
  • matte finish
  • All day wear that is sweat, humidity and exercise resistant

Key Ingredients:

What’s impressive about this Smashbox hydrating foundation formula, is the inclusion of hyaluronic acid, which, unlike other matte foundations, doesn’t dry your skin out, but rather keeps it matte and hydrated – which is the perfect combination.
This Studio Skin foundation is water based and therefore needs to be used with a water-based primer. The Smashbox photo finish primer water, which is both a makeup primer and setting spray, is my staple primer and is one of the best Smashbox primer products to include in your makeup range.
To set my studio skin foundation, I use the Kryolan translucent powder, which is most effective for my combination skin type.
It’s non-comedogenic – meaning that it does not have ingredients that can cause clogged pores resulting in breakouts, additionally, this formula is also oil free.


For me, this Smashbox liquid foundation is indeed long wearing, I wore it for a maximum of 18 hours once and there was no oily residue, however, the makeup did shift and rub off on my nose area.
Although the formula is matte, it’s easy to apply this foundation, as it doesn’t dry out with skin contact immediately, therefore you are able to blend for effective coverage.
I did find that my pores (even with a primer) were accentuated with this foundation as well as slight breakouts, which looked more dramatic than they should – which isn’t a plus for me, this is perhaps a result of the thick consistency of the liquid. My fine lines were somewhat visible but not accentuated.
As a result, this foundation will suit someone without visible pores or breakouts.
A plus is that Smashbox foundation shades have 34 variations to choose from.
For my yellow undertone  – 2.16 was a good match but not perfect. I suppose the browns were too overpowering in this formula – which can make yellow undertones look a bit dull.

 It’s Essential to use a water-based primer and not a silicone-based primer with the Smashbox Studio Foundation, as using the incorrect primer will result in the foundation caking and moving.


  • Long wear up to 24 hours
  • Foundation shades are available in 34 options
  • Does not oxidize
  • Easy to blend
  • Non – comedogenic
  • Cruelty free


  • Accentuates skin imperfections like pores and breakouts
  • Not budget friendly
  • No SPF
  • Slightly dull for yellow undertones


I love the idea of such a long-wearing foundation and this would be the perfect Smashbox foundation for oily skin. However, I would use a pore minimizer primer with this foundation due to how it reacted with my skin and setting spray after three to four hours so it doesn’t move. Unfortunately, a pore minimizer primer may be too matte, as I prefer a dewy finish with my liquid foundations.

This foundation is definitely staying in my makeup bag for those vacations when we spend hours touring and I still need to look picture perfect 15 hours later!
Overall, this foundation is serious about staying power.

  1. I’m curious why you suggest their foundation will be cakey if used with a silicone based primer…? This hasn’t been my experience. I wear it full coverage. I find if I use their primers the foundations work beautifully. It gets tricky when I use other primers. The company makes dimethicone based primers (a smaller molecule of silicone), so I don’t think they’d make a primer that doesn’t work with their foundation. I find hourglass and CoverFX primers work beautifully with this foundation as well. I find what makes the foundation cakey is the type of setting powder. It needs to be very, very finely milled and applied with a light touch. If you’re heavy handed with powder, the makeup will be cakey. I don’t even set this makeup with powder because it self-setting. Less is definitely more with this foundation.


    1. Thank you for your information – like I said in this blog I used the smashbox water based primer which works perfectly well with this foundation.
      Different skin types react differently to silicone based primers and this was my experience with a silicone primer when used with this foundation and that’s the reason for mentioning it – as this is my blog based on my experiences.
