Get long-lasting wear without the weight in a range of shades to compliment virtually any complexion with Laura Mercier Flawless Fusion Ultra-Longwear Foundation. This popular liquid foundation combines weightless, second skin coverage with a fresh, matte finish that stays true for up to 15 hours of beautiful, comfortable wear.

The oil-free formula is suitable for all skin types, but is particularly beneficial for those with normal to oily skin. Oil and shine are minimised almost immediately and stay controlled all day. The luxurious full coverage helps to minimise the appearance of imperfections, and the lightweight, non-comedogenic preparation will not cake or settle into pores and fine lines.

Laura Mercier Flawless Fusion Ultra-Longwear Foundation is transfer, water, humidity and sweat resistant, so it can be worn with confidence from day to night.

Laura Mercier Flawless Fusion Ultra-Longwear Foundation is a liquid foundation in a long-wearing formula that gives skin a soft, matte finish with medium to full coverage.
Key Benefits:
  • Buildable medium to full coverage
  • Range of shades to suit any complexion
  • Flawless, weightless coverage
  • Long-wearing formula stays colour true for up to 15 hours
  • Dermatologist-tested and non-comedogenic
  • Oil and fragrance-free
How to Apply

Dispense a small amount onto the back of your hand and apply to face with Laura’s Egg-Shaped Sponge or fingertips. For best results, use after your preferred Laura Mercier Foundation Primer.


For the most flawless, natural look, Laura says it's key to avoid over-applying foundation to the middle of the face—where too much formula can accentuate lines and other imperfections. With liquid, crème, or powder, she recommends starting at the outer portion of the face and working inward towards the nose. Focus on one area at a time and be sure to blend well. Avoid excess application around eyes or the contours of the face. Repeat application until desired coverage is achieved.

Remember, use Foundation to even out your skin tone. Use Concealer to camouflage imperfections.

Flawless Fusion Ultra-Longwear Foundation is rated 4.0 out of 5 by 69.
Rated 4 out of 5 by from Good foundation. I like to use this product, but you have to learn how to use it. Is only working if you use a bit, if you put too much skin can look heavy and foundation can break out through the day. i have combination skin type, is not my best foundation, but it works really good for me.

Rated 2 out of 5 by from Too drying for me I bought this as a lighter alternative to my usual foundation and at first was quite pleased with the way it went on. However, fairly soon I but found it looked quite powdery and it was very dry on my face which I felt was ageing. I think I this would be better for more oily skin. Not for me.

Rated 4 out of 5 by from Nice This is a great summer foundation. I sweat a lot and live in a place with high humidity during the summer. I also have oily skin. Dangerous combo for foundations. During the summer, this is a godsend! But as soon as fall hits, this foundation performs totally wrong on my skin. This is fine because it is meant to be a long wear and humidity resistant formula - which it is! But if you have dry skin and live in a dry climate, I would recommend one of Laura Mercier's other foundations like the Lumier. Once the weather is drying, this foundation tends to look caked on and clings to dry spots. But again, if you live in a humid environment, give this a try.

Rated 4 out of 5 by from Good coverage If you want a full coverage foundation that stays all day and it’s quite matte then I would def recommend this. I have combination skin with redness on my cheeks and around my nose. This foundation blends well and covers all redness. I feel I don’t need to worry if it’s melting off my face half way through the day. I also don’t feel like it sits in any lines or wrinkles. The range of colours is quite good too.

Rated 4 out of 5 by from Fell in love at first use! This foundation... natural looking, full coverage, long wearing... what more to ask for? Laura Mercier’s Flawless Fusion Ultra-Longwear Foundation is beautiful on the skin. It doesn’t cake or disappear throughout the day. It genuinely looks flawless from first application to 16 hours later! Laura you killed it with this foundation!
