The short answer is that your prescription does the heavy lifting, but what you put around it matters more than most people realise.
The wrong cleanser can make tretinoin unbearable. The wrong moisturiser on Roaccutane and your skin will be in bits. And in clinic, we always work with a combination approach alongside whatever's been prescribed; gentle, barrier-supporting basics, niacinamide as a near-universal add-in, and azelaic acid where it's appropriate. The prescription and the routine work together. Neither one replaces the other.
So let's go through each treatment type.
You've Been Prescribed Acne Medication: Here's What to Use Alongside It
Getting a prescription for acne is a big step, and for a lot of patients it's one that's taken a while to get to. Whether you've just left a GP appointment with tretinoin, or you're starting Roaccutane, or you've been put on spironolactone and you're wondering what your routine should look like now ...
This is the article I wish existed when patients ask me that follow-up question: so what do I do with everything else?
If you've been prescribed a topical retinoid (tretinoin, Differin, Treclin)
Topical retinoids are the most evidence-backed treatment we have for acne. They work, but they come with an adjustment period that often looks like dryness, flaking, and sometimes an initial purge where things look worse before they improve. This is normal and expected. It doesn't mean it's not working.
The skincare around a topical retinoid should be doing one thing above all else: protecting the barrier while the retinoid does its job.
If your skin is very sensitive to the retinoid, you can try buffering; apply your moisturiser first, wait a few minutes, then apply the retinoid on top. It reduces irritation without significantly reducing efficacy.
What to avoid: while you're adjusting, step back from anything else that exfoliates: salicylic acid, glycolic acid, AHAs. These can be reintroduced once your skin has settled, but in the early weeks they're likely to tip an already sensitised skin over the edge.
SPF: non-negotiable, every morning. Topical retinoids increase photosensitivity, and any post-acne pigmentation will get significantly worse with UV exposure. We stock a range of Korean SPFs that work particularly well for acne-prone skin: lightweight, no white cast, genuinely non-comedogenic.
If you've been prescribed Roaccutane (isotretinoin)
Roaccutane is the most effective treatment we have for severe or persistent acne, and for the right patient it can be genuinely life-changing. But it's also the most demanding on the skin. Isotretinoin works by dramatically reducing sebum production (which is exactly what clears the acne) but it means your skin becomes very dry, sometimes uncomfortably so.
Skincare on Roaccutane is almost entirely about moisture and barrier support. This is not the time for actives.
Supplements: we recommend Skin Omegas+ from Advanced Nutrition Programme for patients on isotretinoin. Some evidence suggests omega fatty acids help support skin dryness during treatment. It's not a dramatic fix, but it's a useful add-in. If you're on blood-thinning medication or have allergies, check with us before starting.
SPF: every morning, including on overcast days. An absolute non-negotiable.
The skincare approach here is less restrictive than with retinoids or Roaccutane, and our combination approach still applies. Niacinamide is a good companion, it supports the barrier, reduces redness, and helps with the post-acne marks that clindamycin alone won't address. In clinic, we often pair topical antibiotics with azelaic acid as well, which is antibacterial, anti-inflammatory, and helps with pigmentation. It's a useful combination.
Cleanser: gentle and consistent. Cream or oil-based.
Niacinamide: apply before any prescription topical, as described above.
Moisturiser: lightweight and non-comedogenic. The La Roche-Posay Effaclar H Isobiome Moisturising Cream works well, as does the Repair Barrier Repair Cream from Doctrine if you want something a bit more luxurious.
What to be careful about: if you're using benzoyl peroxide alongside clindamycin, apply them at different times of day to reduce irritation. And as always, introduce any new products slowly, even gentle ones, and watch how your skin responds.
SPF: daily, every morning. (Notice a trend here?)
If you're on spironolactone or the pill for acne
Spironolactone works by blocking androgen receptors, which makes it particularly effective for hormonal acne (the cyclical, jaw-heavy kind). Certain contraceptive pills work similarly. These treatments don't typically cause the skin sensitivity that comes with retinoids or Roaccutane, which means there's more room to work with your routine.
That said, hormonal treatment on its own rarely gets the best results. In clinic, we almost always combine it with a prescription topical, whether that's a retinoid, an antibiotic, or something else tailored to your skin. If you're on spironolactone or the pill for acne and you're only using over-the-counter skincare alongside it, it's worth coming in to talk about what else could be doing more.
Our combination approach still applies here: a gentle cleanser, niacinamide before any actives, a good moisturiser, and SPF every morning without exception. Niacinamide and azelaic acid both complement what hormonal treatment is doing; they're managing the surface while the medication works internally.
One thing I always say to patients on spironolactone: it takes time.
Most people don't see significant improvement for three to six months. The temptation to add more products or change things up when results aren't immediate is understandable, but resist it where you can. Give the medication time to work, and let us know at your next appointment if things aren't moving in the right direction.
SPF: daily. Post-inflammatory pigmentation from hormonal acne can be stubborn, and UV exposure makes it significantly worse.
The things that stay the same regardless of what you've been prescribed
A gentle cleanser. Niacinamide before your actives. A barrier-supporting moisturiser. SPF every morning. These apply across the board, no matter what's in your prescription bag, and they're the foundation that makes everything else work better.
What changes is how careful you need to be about everything else.
On Roaccutane, it's almost nothing additional; on a topical retinoid, reintroduce things slowly once you've adjusted; on antibiotics or hormonal treatment, there's more room to layer, but still pay attention to how your skin responds.
And in clinic, we always work with you on this. Getting a prescription is the beginning of the process, not the end of it, and getting the routine right around it is part of how we get the best results.
