The actor Darren Criss, 32, has a lot to say about grooming, diet, fitness and, most important, sleep. Mr. Criss, a San Francisco native who lives in Los Angeles, is so obsessed with sleep that he times it to REM cycles. He has also started a men’s grooming site, the Motley, with the siblings Matthew and Madison Ruggieri, and has just introduced a unisex skin care line called Onekind. Here, Mr. Criss, who is in the war drama “Midway” and is filming “Hollywood,” the new Ryan Murphy Netflix show scheduled for release next year, explains his personal care routine.

Fully Groomed

I have a lot of cleansers, but honestly, this is the one category where I feel like you just need to get your face clean. You use a bar of soap, and as long as it does the job, it’s O.K. Then I use Port Products Sol Defense SPF moisturizer. Then, morning and night, I put on Recipe for Men Under Eye Gel.

For night, I’m biased toward my own products. I do the Onekind Midnight Magic serum — there’s retinol in there — and I use that in tandem with Onekind Dream Cream. Every two days or so, I do the Urth Botanical Resurfacing Mask. I love a lot of their products. I also have the Urth Antioxidant Face Complex. It’s like taking your face to the spa.

The Perfect Shave

I have to shave every day for “Hollywood,” the show I’m on, and it’s really tough on the skin. I have to pay attention to the length of my stubble and the kind of blade I use. If I have a few days’ growth, I like the Executive blades from Dollar Shave Club.
