True Skin Serum Foundation offers medium coverage that you can easily build up by applying more layers.

True Skin Serum Foundation has a natural, skin-like finish. Once it melds with your skin, you won’t know you’re wearing anything. If you prefer a soft-matte finish, you can set it with a Setting Powder!

Our reformulated True Skin Serum Foundation is now boosted with skincare ingredients Niacinamide and Allantoin to help smooth and soothe with every wear. It still delivers the weightless, buildable coverage you know and love.

The existing shades didn’t change, but we added 12 new shades to cater to even more skin tones.

True Skin Serum Foundation is a buildable, medium-coverage foundation with a natural finish. Super Serum Skin Tint SPF 40 is a tinted serum with light coverage, mineral SPF, and a dewy finish. Both formulas are powered by potent levels of skincare ingredients to visibly improve bare skin over time.

True Skin Serum Foundation is designed for anyone who wants medium coverage that looks like skin. Smoothing Niacinamide and soothing Allantoin have benefits for all skin types.

You can apply it with your fingers, a makeup sponge, or a brush—it’s up to you. We like to apply it with our Complexion Brush or Perfecting Buff Brush for the most seamless application.

The best foundation I've tried
I have struggled to find a foundation that I like so when Kosas discontinued what I was using I was dreading the process of finding something new. To my surprise Ilia matched me with Formentera SF1 and it's perfect. I like that it offers subtle but effective coverage. It goes on smooth and I love that it's good for my skin. Also, I was looking for something without SPF, so I'm glad there are still options.

Not the right match
Felt nice on my skin coverage is good however the online tool to match the colour to my previous foundation hasn’t worked so well for me , I got the suggested one but it’s much more orange than mine and is therefore hard to blend

Love the coverage but it is yellow
I read that other people thought the colors were too yellow and orange and I agree. I love how it melts into skin but do think it gives me a yellow tint. I should probably try a cooler shade. I love the skin tint and other products and love how the serum foundation feels on my skin but the color selection is off.
