I say it's never too late... make sure you're drinking enough water, eating enough fruits and veggies + using a basic lotion with an SPF ... i also think if you're going to the gym/exercising it also helps your skin too
1- cleanse
2- exfoliate (about twice a week)
3- tone
4- moisturize
5- sun block
Some moisturizers come with sun block so you don't need a seperate one. Obviously skip no 4 at night. There is so much stuff out there. So many serums, lotions etc. You might wanna add a vitamin C serum/cream somewhere between the toner and moisturizer.
A few good brands are neutrogena, burt's bees, etc. You might wanna give those a try.
oh dude..one more thing, for your skin...u have to make sure u are using a good shave cream, good razor, are shaving properly, replacing razor appropriately, using preshave oil, use a badger bristol brush .. No matter how good gels get..han applied gel can in no way compete with a rich lather applied by a brush. use a good aftershave as well.
i see too many guys go to work on their moving the razor around in repeated passes like a kindergarden kid colouring with a crayon.
