As a Dermatologist, Here's Why It Still Took Me 2 Years to Fix My Daughter's Acne.

Go and look at the package of whatever you're giving your child for their spots.

I'll wait.

Now flip it over. Read the ingredients. See benzoyl peroxide on there? Salicylic acid? Probably adapalene?

Now let me tell you why that bottle, the one your GP recommended and your teenager used every single day, might be the reason their acne is still all over their skin.

I know, because I prescribed it for 26 years.

And it still happened to my own daughter.

I Fell for This for 2 Years (And Wasted £500)

My name is Sarah. I'm 44. I spent 26 years as a consultant dermatologist. Last month was my last day, I've retired.

My daughter Mia started getting spots when she was 13.

Manageable at first. Mainly blackheads on her nose and forehead, and some spots on her cheeks. I wasn't panicking. I'd seen a thousand cases like hers.

I picked up some CeraVe from Boots, got her a gentle face wash, and assumed it would sort itself out.

It didn't.

Over the next few months it got worse. More spots. More redness. The blackheads spread. She started asking to stay home from school on really bad days. She stopped putting her hair up. She started wearing more makeup to cover it (which I'd read made it worse, but I didn't want to say anything and make her feel worse about herself).

I watched her change. The girl who used to bounce into a room started walking in with her head slightly down. She used to love taking photos. Now she turned away from cameras.

This is the part that's hard to admit.

I already knew every ingredient on every shelf. I just did what I was trained to do. So I just started trying things and hoping. Like most of my patients do.

CeraVe blemish cleanser. La Roche-Posay. Clearasil. Acnecide. That tea tree spot gel from The Body Shop. A salicylic acid toner from The Ordinary. A £35 "natural" oil I found on Instagram. And eventually, the prescription I'd have written for any other patient.

I counted 11 products. Around £500 spent in 2 years.

"Either they did nothing at all, or Mia's skin got so red and irritated she stopped using them. And every single time I thought, maybe the next one will be different."

The prescription cream was probably the worst. It smelled like a hospital. Mia used it every evening and within a few days her skin was peeling and raw. She said it felt like her face was on fire for 20 minutes after applying it.

By morning her skin was so dry and flaky she cried getting ready for school. Sometimes she was completely refusing to leave the house.

She stopped using it after 10 days. (I honestly couldn't blame her.)

And back to the beginning.

My daughter's confidence was getting worse. I was only getting more confused.

And the thing I was most scared of was starting to feel inevitable — permanent acne scars.

I've read they appear in 86% of acne cases and stay forever. My husband had those and when we met he told me he was blaming his parents for not taking care of his acne in time.

I didn't want that for Mia.

Something I Never Said Out Loud

Acne during puberty always has a cause. And most of the treatments I prescribed don't actually treat that cause.

During puberty something happens in a child's skin. Hormone levels rise, the oil glands become much more active and produce more oil than the skin can handle. This oil mixes with dead skin cells and clogs the pores.

Then comes the real problem. A bacterium called Cutibacterium acnes lives on all of our skin. And it feeds on this trapped oil. When the pores are full of it, the bacterium multiplies explosively. That is what causes acne. Not dirt, not poor hygiene, not the wrong face wash. A bacterium with an unlimited food supply.

When the immune system detects this overgrowth, it reacts. That is the redness, swelling and inflammation you see on your child's face.

Now here is the part I don't enjoy telling you.

Benzoyl peroxide. Adapalene. Salicylic acid. Topical antibiotics. These are the treatments I prescribed for 26 years. And they do kill the bacteria — that part works. But what they also do is destroy the skin's natural protective barrier.

The skin has a microbiome. Good bacteria that regulate oil production, maintain the barrier, and modulate the immune response. Harsh chemical treatments don't kill just the bad bacteria. They kill everything. The good bacteria too. And without those, the skin barrier thins. It becomes weak and hypersensitive. The immune system starts overreacting to things it would normally manage without any problem.

And here is the consequence: the acne comes back. But worse. Because the skin is now more vulnerable than before the product was applied. And you repeat the cycle and continue damaging the skin. The GP prescribes something stronger. That damages the barrier further. The inflammation escalates.

I watched this cycle repeat over a thousand times in my clinic. And I kept writing the next prescription anyway. What else is a doctor supposed to do? The NHS pays for it. Parents hope for it. You do what you were trained to do.

Mia's towels had pale patches on the ones she used when she was on the Acnecide.

She did use the moisturiser. She layered it on top of her prescription cream every morning just to make her face feel normal. A moisturiser to protect her from her own acne treatment.

The reason nothing works long term isn't because acne is untreatable. It's because the treatments were built for adult skin, at adult concentrations, and nobody ever asked what that does to skin that's still developing.

Teenage skin is not just a smaller version of adult skin. It is a fundamentally different organ at a fundamentally different stage of development. And we have been treating it with blunt instruments.

I thought: every single one of those 11 products, including the prescribed ones, was potentially making the problem worse each time.

We didn't get unlucky. We got caught in exactly the cycle I'd watched play out in my own clinic for 26 years.

What I Went Looking For

So I did the only thing I could do. Not as a doctor this time, but as a responsible mother. I went looking for something that actually solved the cause without destroying her skin to do it.

The answer was something that's actually been available for centuries. Many big brands just stopped using it when it became cheaper to manufacture synthetic alternatives.

Calendula isn't some exotic discovery. It's not expensive lab technology. It's a plant-based ingredient that does something no harsh gel can — it specifically targets the bacteria that cause acne, without damaging the skin.

It does not just destroy everything. It does not strip the barrier. It does not damage the good bacteria. It targets what is causing the problem and keeps the rest of the skin's ecosystem protected.

At the same time, calendula's active compounds have a well-documented anti-inflammatory effect. The immune reaction calms down. The redness and swelling reduce. And because the barrier is not being damaged, the inflammation does not return.

The skin heals properly. And stays healthy.

I asked myself why I never told my own patients this. Why none of the 11 products we tried had calendula in them.

I know the answer now. Calendula is expensive to source and process at a meaningful concentration. Synthetic actives cost pennies to produce. The industry almost always chooses cost. And nobody has a financial incentive to tell you that these cheaper options damage teenage skin long term, because a customer whose child's skin keeps cycling through breakouts will keep buying products. (The brand products are certainly not cheap — just the ingredients are.)

I felt something shift. Not quite anger. More like clarity.

We didn't fail. The products failed us.

I Found What I Needed

I spent the rest of that night searching. I wasn't even necessarily looking for a product. I was looking for something with a meaningful concentration of calendula — a formula actually built around it.

At first, most things I found with calendula just had it as a marketing word on the front, with the real active ingredients still being a ton of other chemical things or water.

Then I found a yellow balm by a brand called Enduorin. It wasn't a cream or gel — it was actually a balm, full of natural ingredients. Calendula as the primary active ingredient, in a high concentration, combined with sea buckthorn, borage oil, thistle oil and rosehip. 0 benzoyl peroxide. 0 salicylic acid. 0 harsh chemicals of any kind.

Sea buckthorn for skin regeneration and barrier repair. Borage for its gamma-linolenic acid content which supports barrier integrity. Rosehip for its natural retinoid-like properties (skin renewal without the irritation of synthetic retinoids). Thistle oil for sebum regulation.

Every ingredient chosen for a specific role in either fighting the bacterial cause or rebuilding what the previous treatments damaged.

I started reading the reviews. And I recognised them immediately.

I ordered, still slightly doubting that after 2 years and 11 failed products, I might have just found the thing that would actually work. (I'd heard "natural" claims before.)

What Actually Happened — Day by Day

Why This One Worked When Nothing Else Did

Now I understand it even better and I'm actually allowed to share everything. The other products did 2 things simultaneously: killing the bacteria short term while damaging the barrier long term. So the inflammation reduced briefly, then returned worse, because the skin was now more vulnerable than before.

Enduorin doesn't work like that. It targets only the bacteria that cause acne, leaving the barrier intact and the good bacteria in place. So as the bacterial load reduces, the immune system calms down and because the barrier is being strengthened rather than stripped, the inflammation doesn't come back.

It's not a stronger version of what we tried before. It's a completely different approach. And that's why it worked when the other 11 things didn't.
