When we're 20, stocking our bathroom with a moisturiser is as important as a cleanser. Moisturising our skin is a sure fire way to keeping it supple, plump and glowing. And last but by no means least, to slow down the ageing process. A good hydrating moisturiser is all you'll need until you reach your 30's to keep your skin in good nick. It's an important step - if our skin's protective barrier (the hydrolipidic film) isn't kept in tact, then our epidermis will dehydrate. Once our skin gets low on water it feels tight and dry. Our complexion dulls and our skin can start to flake. And that's when wrinkles will crop up! The golden rule? To moisturise morning and night... Sorry, no negotiation! Apply a facial moisturiser that's designed for your skin type to clean, dry skin. Useful tip: moisturising lotions are better for combination or oily skin and thicker creams for dry skin. As you reach 25, you can start to use an eye contour treatment. This is more of a preventative measure to avoid the appearance of fine lines. And dreaded crow's feet!
