I’ve thrown a lot of money at my face over the years. A lot. We’re talking a shelf that looked like a beauty editor had a breakdown in a Boots. Serums stacked on serums, acids next to more acids, a moisturiser for morning and a different one for night and honestly a third one I bought because it had nice packaging and I was tired.
And my skin? Still a mess. Still reactive, still red, still doing weird flaky things around my nose that no amount of hydrating mist was fixing.
It took me an embarrassingly long time to figure out that the problem wasn’t that I needed more products. It was that I needed to stop.
The Biggest Mistake: Doing Too Much
Here’s the thing nobody wants to hear when they’ve just spent £60 on a new serum. More is not better. With skincare, more is often just more irritation dressed up as a routine.
I have rosacea and seborrhoeic dermatitis. My skin is reactive at the best of times. And for years I kept adding products – because when something wasn’t working, my instinct was to throw another product at the problem. Another layer, another active ingredient, another step that some YouTube video promised would fix everything.
What was actually happening? My skin barrier was getting absolutely battered. It was so busy reacting to six different actives that it had no capacity left to just… be skin.
If your routine isn’t working, before you buy anything else, strip it back. Cleanser. Moisturiser. SPF. That’s it for two weeks. See what happens. It’s boring. It works.
I write about building a gentler, more considered approach in my guide to treating facial seborrhoeic dermatitis if your skin is dealing with more than just general reactivity.
You’re Probably Not Patch Testing (I Know, I Know)
Every skincare article tells you to patch test. Every single one. And almost nobody does it, because you’ve just bought an exciting new thing and you want to put it on your face right now.
I have done this. I have paid for it. I once introduced a new toner, a new serum and a new moisturiser in the same week and then spent the next fortnight trying to figure out which one had turned my face into a red, flaky situation. I genuinely couldn’t tell. Had to ditch all three and start again.
Introduce one new product at a time. Give it two to three weeks before you add anything else. Yes it’s slow. Yes it’s frustrating. Yes it’s the only way to actually know what your skin thinks of what you’re putting on it.
The Ingredients That Don’t Play Well Together
This is the one that catches people out the most, and it caught me out too.
Vitamin C and niacinamide used to be considered a bad combination – there was a lot of noise about them cancelling each other out. The current thinking is more nuanced than that, but it’s still a good example of how some ingredients just don’t work well layered together.
The ones that genuinely do cause issues if you’re not careful:
Retinol and AHAs/BHAs in the same routine can cause serious irritation, especially if you’re new to either. They’re both doing quite intense things to your skin and doing them simultaneously is a fast track to a damaged barrier.
AHAs and vitamin C together can be similarly problematic for sensitive skin – both are acidic and layering them can tip your skin into irritation territory.
Benzoyl peroxide and retinol basically cancel each other out. There’s no point using both.
If you’re using actives, look up whether they work together before you layer them. A lot of confusion about why skincare “isn’t working” comes down to products undermining each other.
On the topic of retinol – I switched to prescription tretinoin a while back and it genuinely changed things for me. I wrote about the whole experience in my Dermatica tretinoin review, including how I buffer it so it doesn’t wreck my rosacea skin.
You’re Not Giving It Enough Time
We live in a world of instant everything and skincare does not care about that at all. At all.
Most products need four to six weeks of consistent use before you’ll see a meaningful difference. Prescription-strength actives like tretinoin can take three to six months. Three to six months of your face potentially looking worse before it looks better – which is a really fun thing to commit to, trust me.
I’m not going to tell you I was patient about this. I switched my tretinoin out twice before I stuck with it long enough to see what it actually does. And now I won’t stop using it. But I wasted months chopping and changing because I expected faster results than my skin was capable of delivering.
If a product hasn’t caused a reaction and isn’t actively making things worse, give it its full shot before you decide it’s not working.
SPF Is Non-Negotiable (Sorry)
I know you know this. I’m saying it anyway because SPF is the single most important thing in any skincare routine and it’s the step most people either skip entirely or half-heartedly apply on sunny days only.
UV damage doesn’t clock off when it’s grey outside. It doesn’t take bank holidays. It is happening all year round and it undoes basically everything else you’re doing if you’re not blocking it.
If you use any kind of active ingredient – retinol, AHAs, vitamin C – SPF isn’t optional, it’s essential. These ingredients can increase photosensitivity, which means skipping sunscreen is actively working against the products you’re using.
I spent a long time hunting for an SPF that worked for my reactive, rosacea-prone skin without leaving a white cast, sitting weirdly under makeup, or just feeling like I’d applied wallpaper paste to my face. Korean sunscreens changed my life a bit, honestly. The formulations are so much lighter. Worth looking into if you’ve always found SPF to be the worst step in your routine. I’ve got a whole post on Korean skincare products that helped my rosacea if you want somewhere to start.
The Simple Stuff Works
My routine right now is genuinely boring. A gentle cleanser, one serum, a moisturiser, SPF. That’s it. No stacking, no layering six actives and hoping for the best. (Except when I’m testing products for the blog – in which case all bets are off and my skin is basically a lab rat. Occupational hazard.) And my skin is the best it’s been in years – which I find slightly annoying given the amount of money I spent getting here. But there it is. The boring stuff works. It really does.
If you’re working out your own routine from scratch, my post on malassezia safe moisturisers is a good place to start if you’re dealing with any kind of fungal-related skin drama. And my Anua azelaic acid serum review covers one of my current favourite single-active serums for sensitive and rosacea-prone skin.

FAQ: Why Isn’t My Skincare Routine Working?
How long should I give a new skincare product before deciding it doesn’t work?
Minimum four weeks for most products, and honestly closer to eight to twelve weeks for anything targeting pigmentation, texture, or fine lines. Prescription-strength ingredients like tretinoin can take three to six months. I know that’s not what you want to hear. But pulling a product after two weeks and replacing it with something new is how routines spiral into chaos.
Can you use too many skincare products at once?
Yes, absolutely. Layering too many actives at the same time is one of the most common reasons reactive skin gets worse instead of better. Your barrier can only handle so much. Strip back to basics – cleanser, moisturiser, SPF – and add things back in one at a time.
What skincare ingredients should you not mix together?
The main ones to be careful with: retinol with AHAs or BHAs (irritation risk), AHAs with vitamin C (both acidic, both potentially irritating layered together), and benzoyl peroxide with retinol (they cancel each other out). If you’re using multiple actives, it’s worth looking up compatibility before you layer them.
Why does my skincare make my skin worse?
A few likely culprits: you’re using too many actives at once, you’ve introduced multiple new products simultaneously so you can’t identify the problem one, or you’re using ingredients that don’t work well together. It could also be a fragrance or alcohol sensitivity – worth checking ingredients lists on anything new. When in doubt, strip back and start again.
Is SPF really necessary every day even in the UK?
Yes. I say this as someone who spent years half-heartedly applying SPF only in summer. UV damage happens year-round regardless of whether the sun is actually visible. If you’re using any kind of active ingredient – retinol, AHAs, vitamin C – SPF is non-negotiable because these ingredients increase photosensitivity.
What’s the best skincare routine for rosacea-prone skin?
Simple. Genuinely simple. A gentle, fragrance-free cleanser, a barrier-supporting moisturiser, and an SPF formulated for sensitive skin. Add actives very slowly and one at a time, and look for calming ingredients like niacinamide, centella asiatica, and azelaic acid. I’ve got more on this in my seb derm treatments post.
