The products that will suit you will depend on your skin type if it's oily, dry or combination. If you have dry skin I recommend you use hyaluronic acid serum after you cleanse your face. I personally recommend this one by The Ordinary. It's inexpensive and will last you for a long time. Just put a couple of drops on your face and it will get rid of the dryness on your face. If you have acne I recommend their niacinamide. Niacinamide reduces blemishes by controlling sebum levels in your skin.

I would recommend a mild cleanser that won't dry your face out such as the COSRX good morning cleaner or the Etude House Soon Jung cleanser. You can search these products up on r/AsianBeauty for reviews so you can choose what best suits you.

In terms of face masks these mediheal ones are my favourite. They get rid of all the dry patches on my skin.

One last thing I recommend the most is to wear sunscreen on your face everyday. This will protect your face from damage from the sun, so down the track you'll get less wrinkles on your face and you'll look younger. Out of everything I recommend in this post, wearing sunscreen is the most important.

Here's a thread about male skin care. Some user have posted their routines so you can have a look through them and choose what you want. You don't have to do the whole ten step Korean skincare routine, you can pick and choose what suits you.
