Remove make-up thoroughly before you go to bed. You could use a wet wipe first, cleanse, then moisturise. Or you can just skip straight to washing it off, then moisturise.
Rely on your facewash and scrub to remove unwanted roughness and blackheads, rather than picking at your skin – especially with dirty fingernails!
Keep your moisturiser in a cool, dry place. This is to keep its ingredients stable.
Stick to a moisturiser that works for your skin instead of constantly switching products.
