Vitamin D won't help reduce wrinkles.
There are many ways to prevent the appearance of aging, including reducing your exposure to UV rays, using moisturizing products, and getting your solid eight a night.
Blackheads are caused when sebum is exposed to oxygen.
Both whiteheads and blackheads involve your pores getting clogged with sebum (aka, "skin oil"), but blackheads expose melanin from the clogged pores to oxygen, which causes them to look dark.
Wash your face with lukewarm water.
You've probably heard quite a few arguments about hot vs. cold, but it turns out you shouldn't be washing your face with either. Extreme temperatures can irritate and dry out your skin, so stick to something lukewarm.

You should gently pat it dry with a clean towel.
Going to town rubbing your face with a towel might make you feel like you're doing good work by getting in some extra exfoliation, but it can actually pull at your skin in a way that damages the elastin. Also, obviously use a clean towel: You just finished cleaning off the bacteria, and you don't want to put it right back on.

While you might not use all of these products and thus might miss a step or two, this is the correct order.
Niacinamide is the correct spelling of this skincare ingredient.
Niacinamide is a form of B3 and has been touted for its anti-aging properties.
Codules are not a form of acne blemish.
Acne blemishes come in many forms, but codules aren't one of them. Papules are small red or pink spots, pustules appear to be full of puss and are ringed with red, and cysts are bigger lesions that are full of puss.
