@AlohaMolly yes to using night cream after cleansing. You need to get the dirt and pollutants from the atmosphere off your skin and feed it with a night cream. The body repairs itself while we sleep. SPF is Sun Protection Factor, the higher the better, that's for UV B rays. UV A rays have a star rating from one to five stars, the higher the better. For daytime you want a cream with both UVA and UVB protection, it will say on the packaging if it has them. It's in some face creams already, but usually at a low level. You can also use your usual face cream without any UV protection and then use a separate sunblock cream on top.
I don't focus so much in looking younger I just try not to look old, which I think is about making an effort. I see people who are only in their 20s but they look awful, they look more like how you expect someone old to look, like it's all about comfort and convenience. That's fine if they're happy looking like that, but I don't want to look like that.
I don't follow fashion too much, but if something is totally and completely out of date I won't wear it. I don't see that happening any more thought, which is good, current fashion seems to be wear whatever you want. I buy from fashionable shops so whatever I buy is automatically current. I never choose comfort over style, items need to fulfill both criteria.
Skincare is cleansing followed by serum, oil, gel cream, moisturiser and sunblock, then makeup. At night I use a face wash, a more intensely moisturising serum, plus the other things but no sunblock. I bath daily and use body moisturiser too. This is all because I have eczema and is what's needed to keep it under control.
I'm pescetarian and drink lots of water and herbal tea. Do yoga and always get 8hrs sleep. I like to get outside into daylight and fresh air and nature. I don't do this to look young it's just my lifestyle.
