What are the best products to use with Curology? Curology does a brilliant job of giving you a personalised prescription formula: licensed dermatology providers looks at your skin, your acne history, your dark spots, your whole situation, and blend you a custom formula with prescription-strength actives like tretinoin, azelaic acid, niacinamide tailored specifically to you… And then kind of leaves you to figure out the rest yourself. Which is fine if you know what you’re doing. Less fine if you’re standing in your bathroom at 11pm holding your existing vitamin C serum wondering if it’s about to become your enemy.
Because your Curology formula doesn’t work in a vacuum. It’s going on your face alongside your cleanser, your moisturiser, your SPF, whatever else you’ve got going on – and some of those products will actively support what your prescription is trying to do, and some will completely undermine it. The wrong combination can wreck your skin barrier, cause unnecessary irritation, or just straight up cancel out ingredients you’re paying good money for. This article breaks down exactly what to use alongside your Curology formula, what to bin, and why (based on actual research, not marketing copy).
What’s Actually In Your Curology Formula?
Before we get into what to pair with it, you need to know what you’re working with, because the answer genuinely depends on your specific prescription. Curology formulas vary from person to person based on your unique skin type and skin concerns, but most prescriptions are built around some combination of tretinoin, azelaic acid, and niacinamide, so let’s take a closer look at them and what they can actually do for your skin:
- Tretinoin: It’s a prescription-strength retinoid and it works by speeding up how fast your skin turns over dead skin cells and produces new ones. The results? Clearer pores, fewer acne breakouts, faded dark spots and age spots, smoother texture, better collagen production over time. It’s also the reason your skin might go through a rough patch when you first start – dryness, flaking, irritation, the occasional “why does my face look worse” moment that makes you want to bin the whole thing. That’s normal, it passes, and it’s exactly why what you put around your Curology formula matters so much.
- Azelaic acid:Anti-inflammatory, antibacterial, fades pigmentation, works on all skin tones without causing more pigmentation issues in the process (which is more than you can say for a lot of acne treatments). It’s genuinely underrated and one of the best topical treatments for sensitive skin dealing with dark spots or redness alongside their breakouts.
- Niacinamide: It does roughly everything: strengthens the skin barrier, reduces excess oil, calms inflammation, fades pigmentation. It also plays nicely with other skincare ingredients, making them easier for your skin to tolerate them.

Building The Best Skincare Routine To Support Your Curology Products
Mandatory: A Gentle Cleanser
Tretinoin is already harsh on your skin, so what you want is a genuinely boring cleanser: Fragrance-free, low-foam or no-foam, nothing that makes your skin feel tight afterwards. That squeaky clean feeling everyone used to think meant a cleanser was working? That’s your barrier being stripped. Not what we’re going for here. CeraVe Hydrating Cleanser is my top recommendation. It’s very gentle and gets everything off. La Roche-Posay Toleriane Hydrating Gentle Cleanser is another great option for very sensitive skin that stings whatever you put on it. Curology does make their own cleanser which is obviously going to be compatible with their formula, so if you want to just keep everything in the same ecosystem and not think about it, that works too. Just please, if your cleanser has glycolic acid or salicylic acid in it, retire it for now. You don’t need exfoliating acids in your cleanser when your prescription formula is already doing the heavy lifting.
Mandatory: A Proper Barrier-Repair Moisturiser
If there is one thing the clinical research on retinoids screams loudly and consistently, it’s that you need a good moisturiser. A PubMed study on subjects using topical tretinoin found that applying a moisturiser alongside it gave significant improvements in dryness, roughness, and desquamation ( the medical word for skin flaking off). The specific ingredients that do the work? Ceramides, cholesterol, and fatty acids. They’re the things your skin barrier is literally made of, so when tretinoin disrupts it, replenishing those exact lipids is the most direct fix there is. Research into soothing agents for retinoid-induced irritation also found that panthenol and acetyl glucosamine help significantly with barrier repair and reducing irritation.
What this looks like in practice: CeraVe Moisturising Cream is the most recommended one and with good reason: three types of ceramides, glycerin, hyaluronic acid, dimethicone, fragrance-free, cheap. If you have oily skin or acne-prone skin and the idea of a rich moisturiser makes you nervous, a lighter gel moisturiser with hyaluronic acid and niacinamide works. Just make sure it actually has some barrier-supporting ingredients in it and isn’t just water with a nice smell. Or you an use the Curology moisturizer formulated for your skin type.
One thing worth knowing: you can apply your moisturiser before your Curology formula as a buffer (moisturiser, wait a few minutes, then apply the formula) which reduces irritation without affecting how well the actives work. Useful when you’re first starting out and your skin is still getting used to everything.

Mandatory: SPF Every Single Morning
Tretinoin speeds up cell turnover, which means newer, more delicate skin cells are sitting at the surface of your face, and they are not as equipped to handle UV exposure as the older ones they replaced. Studies show that tretinoin and sun protection work together as a unit – you don’t get the full benefit of one without the other, and skipping SPF while on a retinoid is genuinely counterproductive. In case you’re wondering, both chemical sunscreens and physical sunscreens work fine for most people. A physical sunscreen with zinc oxide is best for sensitive or acne-prone skin because it tends to be less irritating, but can leave a white cast.
Optional: Vitamin C Serum In The Morning
Vitamin C works best in the morning, where it acts as an antioxidant against the free radical damage caused by UV exposure – damage that accumulates over time and causes exactly the kind of pigmentation, fine lines, and dullness that your Curology formula is also trying to fix. They’re working on the same problems from different angles at different times of day. The research on formulation is specific. Studies found that the most effective vitamin C formulation is L-ascorbic acid at 15%, combined with 1% vitamin E and 0.5% ferulic acid. Adding vitamin E potentiates vitamin C’s effects fourfold, and adding ferulic acid on top of that increases efficacy eightfold compared to vitamin C alone.
SkinCeuticals C E Ferulic is the gold standard. Paula’s Choice C15 Booster is a good dupe. Timeless Vitamin C + E Ferulic Serum uses the same combination, with a higher dose of Vitamin C. I personally recommend you start WITHOUT Vitamin C and, one or two months down the line, when your skin has gotten use it to it, you can add a Vitamin C face serum to your morning routine again. Using too many actives at once can irritate skin. Give it time to settle first.
Optional: Exfoliants
Salicylic acid, glycolic acid, lactic acid… Lots of people have these in their routine and don’t want to give them up, and honestly you don’t necessarily have to. But you do need to be smart about it. Tretinoin is already exfoliating your skin by accelerating cell turnover. If you pile acid exfoliation on top of it on the same night, you are over-exfoliating, and over-exfoliated skin on a retinoid looks terrible and feels worse – red, raw, tight, reactive.
The practical fix: quit exfoliants when you first starting using your Curology personalized formula. If, a few months down the line, once your skin has gotten used to it and you’re not experiencing side effects anymore, you want to reintroduce it, do so carefully. Use your exfoliant on nights you’re not applying Curology. Alternate the two rather than stacking them. Once a week is a sensible starting point. See how your skin responds before increasing frequency.
Optional: Benzoyl Peroxide
Benzoyl peroxide is one of the most effective acne treatments that exists. It targets acne-causing bacteria in a way that very few other ingredients do – and bacteria don’t grow resistant to it. The issue is what happens when it meets tretinoin directly. A pharmaceutical stability study found that benzoyl peroxide degrades tretinoin rapidly and significantly – 50% of the tretinoin molecule is gone within two hours of contact, and 95% within 24 hours. So if you’re applying BPO and your Curology formula in the same routine, you’re basically dissolving your prescription. That’s an expensive mistake. The fix is so simple it feels almost too easy: First of all, you do NOT need both. Your Curology prescription skincare should be enough. If not, use benzoyl peroxide as an emergency spot patch treatment in the morning and Curology at night.

What NOT To Use Together With Your Curology Skincare Regimen
- Essential oils in your skincare: Fragrance (natural or synthetic) is a common cause of irritation and barrier disruption, especially on skin that’s already adjusting to a retinoid. If your moisturiser or serum smells like a spa, check the ingredient list 9and leave it on the shelf).
- A second retinoid on top of your Curology formula: if your prescription already contains tretinoin, adding an OTC retinol serum is redundant and just loads more irritation onto skin that’s already working hard. You don’t need it. More retinoid is not more results – it’s just more dryness.
- Anything your skin doesn’t need right now: the adjustment period is not the time to experiment with new actives. Get your skin stable on Curology first, then add things back in one at a time so you actually know what’s doing what. A simple skincare routine words bet.
The Bottom Line
Morning: gentle cleanser, vitamin C serum, moisturiser, SPF. That’s it.
Evening: gentle cleanser, let your skin dry completely – wet skin increases absorption and makes irritation worse – then your Curology formula, then moisturiser.
On nights you’re not using Curology, if your skin is acclimated and handling things well, that’s when an exfoliant can go in.
Simple. Boring. Effective. Your licensed dermatology provider has done the complicated bit by creating your prescription formula – everything around it just needs to support your skin barrier, let the actives do their job, and not get in the way.
