Usually I don't fall for cure-all creams, so the "multi-corrective" in Kiehl's Super Multi-Corrective Cream (£48) had me sceptical. However, consider me converted. The three primary ingredients in this product are jasmonic acid to repair wrinkles, beech tree extract to maintain firmness, and fragmented hyaluronic acid for moisture. The jar label touts improvements after two weeks, but I saw positive changes after only one night. I woke up with bright and glowing skin. Since this product is a thicker cream, a little goes a long way. For me, it works best as a nighttime treatment (like right after a girls' night out with lots of cocktails) when I don't have the energy for anything but a face wipe and one treatment. It's even moisturising enough that you can skip eye cream altogether. Margaritas — what margaritas?
