A Fine Line
What you need: Wrinkle-filling serum + liquid concealer.
What to do: Legend has it that Hollywood actors used to apply melted paraffin to their skin to obscure fine lines. Today wrinkle-filling products can serve a similar function as the wax (with less mess); they contain ingredients such as silicone, which sinks into lines and helps smooth them out. Squeeze a bit on your finger and tap it into the wrinkle until it is less detectable. Top with a liquid concealer to hide any remaining evidence of a line. Skip powder, which can cling to lines and call attention to them.
