Serum-dipity

I love a serum. It is the one product that I feel is essential to keeping the skin in good shape as we age. They are far more potent than moisturisers and penetrate deeper, and  although usually expensive, a little goes a long way. The work of a good serum is usually to hydrate, improve collagen levels, brighten or fight free radicals . The molecules in a serum are smaller than the molecules in a moisturiser so they can penetrate the 3 layers of skin instead of just the first layer. So used in conjunction with a good moisturizer it ensures that you get added nutrients into the deeper layers of the skin.
When choosing a serum you first need to decide what type of skin you have (normal , oily or dry ) and what it is you want to achieve by using it. To prevent ageing you would use something with antioxidants. To reverse ageing it would be one that had Vitamin A or hyaluronic acid to nourish the skin. 
I use serums under my moisturiser and a few of my favourites are ASAP Super C serum, Dermaquest C3 serum & Skinceuticals Serum 20 AOX. These ones stimulate collagen production, contain antioxidants to fight free radicals and help brighten the skin... 3 in 1 .The other favourites are the Dermaquest B5 serum & Skinceuticals Hydrating B5 Gel which contain sodium hyaluronate for hydrating the skin.  I feel between the Vitamin B & the Vitamin C I should have everything covered to give my skin maximum nutrients.  Dermaquest have also just released a new B3 product called Niacinamide Youth Serum which is meant to improve uneven skin tone and fine lines. ( It's funny how anything with the words youth and skin in it makes you want to immediately give it a go ).  I tried a sample of this but I think it was too rich for my skin as I have broken out in spots and the difference in my skin isn't noticeable enough to persist, so would stick with the B5 serum . As my skin tends to get oily, I think it is better applied to dry skin.
So if you're looking to do abit more for your skin to keep it in great condition - why not try a serum or two .... your skin will definitely thank you for it. xx
