In 1942, when flour began to be enriched with nicotinic acid, a newspaper headline read "Tobacco in Your Bread." The alarm was enough that the food and nutrition board backed by the American Medical Association coined a new word, niacin, just to keep the vitamin well away from nicotine. It had been pulled out of liver by Conrad Elvehjem in 1937. Its amide form, niacinamide, now sits near the top of half the oily-skin labels you will ever read.

That is a neat piece of rebranding, and it is also how I think about oily skin products in general. The word on the front matters less than what is inside. The CeraVe Oil Control Moisturizing Gel-Cream puts niacinamide second on its ingredient list, right after water, with glycerin, three ceramides and hyaluronic acid behind it. The brand says it is lightweight, oil-free, non-comedogenic and fragrance-free, and that its oil-absorbing technology leaves a matte finish. It is made for combination to oily skin, and it does not try to strip anything. CeraVe traces its story to 2005, when experts noticed that acne, eczema, psoriasis and dry skin all share a compromised barrier, and L'Oréal has owned the brand since 2017. That barrier-first view is the interesting idea here.

The trick is to keep the rest of the routine as gentle as the moisturizer. The Foaming Facial Cleanser is the obvious partner for morning and night, and the Renewing SA Cleanser is there for the days you want a little more from a wash. In the morning, the AM Facial Moisturizing Lotion SPF 30 covers sun, and the PM Facial Moisturizing Lotion is the easy night option if the gel-cream feels like too much in winter. The Ultra-Light Moisturizing Gel and the Ultra-Light Moisturizing Lotion SPF 30 are the lightest rungs on the ladder, good for humid weeks. The Acne Control Gel Blemish Treatment is the spot-by-spot one you keep by the sink.

Change one thing at a time, and give it two weeks. Oily skin tends to get a new product every time a forehead shines, which makes it impossible to tell what is helping.

Once the base is settled, the rest of the CeraVe shelf is easy to add a piece at a time. The Hydrating Hyaluronic Acid Serum goes under a moisturizer and suits skin that is oily and dehydrated at once, which is more common than people admit. The BHA Exfoliating Toner with Salicylic Acid is for clogged pores, and I would start it a couple of nights a week on a clean face. The Resurfacing Retinol Face Serum belongs to the evening, and the Skin Renewing Vitamin C Serum belongs to the morning, so you do not need to choose between them.

The Blemish Barrier Patches are the small, sensible one. A patch on a spot at night keeps you from picking, and that alone does most of the work. For the eyes, the Skin Renewing Eye Cream and the Eye Repair Cream for Dark Circles & Puffy Under Eyes are two options, and the Hydrating Facial Toner is the soft wipe for anyone who finds the BHA toner a bit much.

A pairing I like: the hyaluronic acid serum on damp skin, then the gel-cream on top. The serum holds water, the gel-cream keeps it there, and the two together feel like very little.

What I would skip: the BHA toner and the retinol on the same night when you are new to both. Introduce one, then the other.

Press the back of your hand against your cheek an hour after moisturizing. If it feels slick, the formula is too rich for you. If it feels tight, you have gone too far the other way. The right gel cream feels like nothing, and it is worth trying a few to learn where your line is.

The shelf of oil-free gel creams is crowded, and each brand has a different personality. Kiehl's Ultra Facial Oil-Free Gel Cream is refillable and a dependable, plain choice. Laneige's Balance Mode Shine Control & Pore-Minimizing Lightweight Moisturizer is for people whose main complaint is midday shine. Tatcha's The Water Cream is also refillable and oil-free, the most luxurious feeling of the group. The INKEY List's Omega Water Cream adds niacinamide at the simple end of the shelf, and Paula's Choice CLEAR Oil-Free Moisturizer is the one for skin that breaks out as well as shines.

Glow Recipe's Watermelon Pink Juice moisturizer is the fun one, with a fruity personality that I can see working in a hot summer routine. Sofie Pavitt Face's Skin Jelly is a bouncy oil-free gel, and Sephora Collection's 8HR Oil Control Moisturizer with prebiotics and polyglutamic acid is the quiet, dependable option for someone just starting out.

What I would skip: a thick night cream on top of any of these. They are designed to stand alone, and layering a rich cream over a gel cream defeats the point.

Blot, do not wipe. Pressing a sheet against a shiny spot for a few seconds lifts the oil and leaves your makeup where it was, and rubbing just moves everything around.

The blotting paper is the smallest tool here and the one I would put in every bag. Sephora Collection's Matte On-The-Go Blotting Papers come in a slim pack that fits a pocket. On the primer side, Dior's Forever Velvet Veil is a blurring, pore-refining matte primer with SPF 15, the polished one. Benefit's The POREfessional is the classic pore-minimizing primer, Make Up For Ever's Step 1 Primer is the shine-control option, and ONE/SIZE's Oil Sucker Prep & Refresh Mattifying Duo gives you a prep step and a midday refresh in one.

Then the niacinamide row, where the main question is how much you want. The INKEY List's Niacinamide Oil Control Serum is the gentle entry. The Ordinary's Niacinamide 10% + Zinc 1% Serum is the famously simple one, and Paula's Choice's 10% Niacinamide Booster is the version you can mix into a moisturizer. Given that the gel-cream already has niacinamide, a serum on top is not essential, and I would start with the moisturizer alone and add a serum later if you want more.

What I would skip: a matte primer on dry days. Oily skin changes with the weather, and so should the routine.

For most people with oily skin, the answer is a moisturizer that does not fight your face. I would start with the gel-cream from the first grid, a gentle cleanser and a daily SPF, and leave everything else until you have a month of steady results. Use it morning and night after cleansing, and follow it with sunscreen in the daytime, as the brand advises.

Then add one thing at a time: a serum, a toner or a patch, whatever your skin is actually asking for. Elvehjem got his vitamin out of liver in 1937, and it still took a few years and a headline to sort out what to call it. Your skin can have a month. If you want to keep browsing, I also put together Shiny Face Moisturizer and The Best Toner for Oily Skin Works Overtime Between Cleansing and Moisturizer.

When the routine itself feels like too much, I laid out the best skincare for oily skin as one active and a light moisturizer.

If you want sun protection in the same step, I sorted the gel moisturizer with SPF for oily skin options by texture.
