I get really tired of these chicks on Youtube acting like you need to apply 27 products that are 90 dollars each to your skin to look acceptable.
That shit is way over the top, and I don't mean this in a judgmental way, I'm just calling out marketing a product for the bullshit it is.
I have a lot of notes from other female ( and male ) models that ask me about skin and keeping it clear. I am 26 now and needless to say other than once or twice a year when I wear "full" makeup, I typically am bare faced or rarely mascara for a bit of lash definition in pictures.
Don't overdo it. Literally. Your skin doesn't need a million products on it to be happy and healthy. Seriously. I don't know where the trend of using a million face oils and moisturizers came from. Its ridiculous.
Avoid extensive sun exposure on your face. I go out wearing hats, whether its a ball cap or a wide brimmed sun hat, often. Sun is the real culprit of aging, which is exactly why I'm as pale as the bloody snow on the ground in most of the world right now.
Obviously, wear sunscreen. I'll admit I don't wear it daily, but I definitely always have a hat on to keep the sun off my face.
Drink water. Your skin is the first thing to show signs of dehydration through dried lips, sunken eyes, and the 'dead' look. You need water, and I'm not going to lecture about 8 cups a day. Just make sure you're staying hydrated.
Avoid excessive alcohol. By excessive, I mean getting shitfaced every day. That isn't good for your liver or your skin.
Get proper sleep. I know its easier said than done in a world that wants you to be "busy busy busy", but getting at least six hours of sleep a night will keep you from looking like a walking zombie. Your body repairs itself when you're sleeping, its vital to your health.
Regarding actual products, witch hazel, is one of my absolute favorite things to lather on my skin. Its an astringent that prevents acne and reduces hyper-pigmentation. Its literally 2 dollars for a giant bottle of it at your local general store, and it smells like high heaven, but its a miracle worker.
A gentle foaming cleanser or cleanser in general to remove dirt, grime, and oil from your skin should be used at least at the end of a long day. I like Boscia, Aveeno is great too, there's a lot of good cleansers out there. You do not need to spend 90 dollars on a facial cleanser. That's fucking ridiculous.
Boscia is a bit pricy, but you can get a sample size at Sephora for like 12 dollars and it's already lasted me nearly two months.
Exfoliate once or twice a week with a chemical exfoliator. I know "chemical" sounds scary, but they're usually just a foaming exfoliator that erodes that top layer of dead skin. The gels with beads in them cause microtearing on the skin that you can't see, and this can lead to breakouts. Microbeads are also ruining our lakes and oceans, so lets leave them off the counter and opt for something a bit friendlier to the waters we love.
Lastly, moisturize. Even if you have oily skin, lotion on the skin helps balance the oil production of your face. If your face is dry, your skin wants to produce more oil to keep it moisturized, leading to an oily complexion and eventually clogged pores. If you have oily skin, look for water based moisturizers, if you have dry skin, look for oil based moisturizers. I like Aveeno.
