It is a lovely serum that doubles as a primer too.
It has a silky-matte finish that has some oil controlling function too.
The formula is silicone-in-water emulsion and contains two silicone oils and a silicone elastomer. The silicone elastomer is the culprit when it comes to clogged pores for some due to that it is occlusive. It can unfortunately also trigger cystic acne and one should be careful if prone to acne.
Silicone elastomers have also the use as an excellent non-drying blurring agent that immediately will temporarily transform all skin surfaces into a more perfect version of themselves without the use of colour cosmetics. Double also as the perfect primer under foundation/coloured day cream etc.
Unfortunately the product is sold for all skin types. While all skin types will appreciate its finish, oilier skin types will incline to like it the most.
It does contain an impressive array of actives (anti-oxidants and cell communicating ingredients) and also some excellent mild exfoliating agents in a higher concentration that also have documented effect (Acetyl Glucosamine, Sodium Lactobionate in 1% concentration each?).
Clinique has a corresponding formula that is marketed as Turnaround Serum but this serum is emulsified by a silicone emulsifier (or rather a mix of two), while the Idealist (being an older formulation) is emulsified and stabilized by two oil-in-water polymeric emulsifiers. This will give Idealist the perception of a lighter feel at application also.
It contains Methyldihydrojasmonate, Limonene and Linalool that are used as the fragrance material. (Can cause allergic reactions.)
