Oh gosh I remember the two hourly wakings - it's a killer. Poor you!
So you want something that's going to give you more of a healthy glow back?
Vitamin C serums are good for brightening the skin. Something with at least 10% l-ascorbic acid is best. Alpha H, Skinceuticals, and Obagi are good brands to try although they can be pricey.
Alpha hydroxy acids (AHA's) such as glycolic and lactic acid and Beta hydroxy acids (BHA's) such as salicylic acid have a mild peeling and brightening effect on the skin also. Vichy Normaderm Global Hydrating Care contains both and can be found fairly cheaply in Boots.
Retinol is a derivative of vitamin A that increases skin cell turnover and encourages the production of collagen, quite literally making the skin act and therefore look younger. The highest percentage it can be sold at without the need for a prescription is 2%. It is converted to retinoic acid on the skin.
Pure retinoic acid or tretinoin can only be purchased in the UK with a prescription, and is usually only prescribed to those with acne, but seeing as your skin is good anyway, an over the counter retinol product sounds as though it will be more than sufficient to give you the boost you're looking for.
Easily accessible brands to look for are ROC, Avene (they do a product called Triacneal with retinaldehyde - which is one metabolic step in between retinol and retinoic acid - in it), and Philosophy. Skinceuticals is a more expensive brand but they do both 0.5% and 1% retinol creams.
Using a retinoid on your skin is a commitment. There is always a period of adjustment during which your skin tends to look worse before it gets better. Side effects can include redness, peeling, dryness, and breakouts. These can last anything from a few weeks to a few months. You absolutely have to wear sun protection of at least factor 30 every day, rain or shine, and once you have achieved the results you are looking for you have to continue a maintenance programme (which usually means just using the retinoid a little less often) otherwise you skin will go back to how it was before you started.
Having said all that I am a huge devotee of retinoid use. My skin has been transformed by it.
