This concealer wears wonderfully all day with no touch ups required (for my skin type - actual longevity will vary for different skin types and whether or not primer is used)
Provides excellent coverage for dark shadows, bags, redness and broken capillaries to name a few things, but it still a lightweight formula and spreads well
The Terrybly Densiless concealer is part of an anti-aging makeup range and it includes anti-aging serum in the concealer to actually treat the under eye area and not just cover it. It visibly plumps and firms the under eye area and smooths wrinkles
Conceals dark shadows, bags and redness moderately well - visibly reduced but not totally gone as it has a more natural finish than some other concealers
Has a very similar fomula to the Nars Radiant Creamy Concealer - slightly less coverage and not as heavy - but a good option if you're not ready to commit to the price tag of the Nars
While the product can have a tendency to migrate into fine lines, the colour and coverage last fairly well during a long day. If migration and creasing are not an issue for your skin then it will last well, if they are then this would be better used as a spot/correcting concealer and not an under-eye concealer
This concealer doesn't melt into the skin and sit with a skin like finish - it tends to sit on top which can give a cakey look and look quite drying in the under-eye region
While this product is promoted as a non-creasing formula, it can indeed crease and settle into fine lines around the eye making you appear much older than you are
