I'm in my mid-twenties too and I've only jut started taking my skincare regimen seriously, so I can't say my method is *proven*
DAY:
1. Cleanse with Pond's facial wash
2. Moisturize with Khiel's ultra facial moisturizer SPF 15
3. Optional face base: Étude House sun BB cream SPF 50 (I actually skip my Khiel's if I put on bb cream, bad I know)
Yes, sunscreen is THE most important anti-aging product out there, so I'm trying to be religious about putting it on. Even indoors. I wash it off at night though because SPF can clog pores. I'm looking for a day lotion to replace my Khiel's actually, because it has parabens and is only SPF 15. Anyone have any recommendations? At least SPF 30?
NIGHT:
1. If needed: Makeup remover Muji gentle cleansing oil
2. Cleanse with Pond's facial wash
3. If needed: Tone with Dickinsons witch hazel toner (will switch to an alcohol-free one when I turn 30)
4. Moisturize face and body with Nivea Baby smoothy cream
5. Eye care with L'Oreal revitalift eye cream
6. Face mask (Étude House, Tony Moly, Snoe, whatever's handy) 1-2x/week
7. Exfoliate with Cetaphil and a soft face towel 1-2x/week
Serums are the next most important thing after sun protection. Women in their twenties should go for serums with antioxidants like vitamins A, C, and E. For those in their thirties, serums with retinol are in order. I'm actually looking for a good one that is not too pricey, any recommendations?
ALSO:
1. Never forget the neck and hands. Even with a fabulous face, these will bear the tell-tale signs of aging. They need moisturizer and sunblock too!
2. Hydrate, hydrate, hydrate! I try to always have a glass or bottle of water beside me. Moisturizers won't work if I'm dehydrated.
3. Get enough sleep at the right time. At least 6 hours straight, like 10pm-4am. In my profession this isn't possible, which is why I'm taking steps to delay the signs of aging.
