In what 7 habits are off limits for dermatologists? I’m reminded of the many conversations I have every week at The Facial Hub skin clinic, where clients often ask which skincare habits a cosmetic dermatologist or medical doctor would never include in their own routines. After nearly two decades of hands-on skin therapy here at The Facial Hub in Brisbane, I can confidently say that the habits dermatologists avoid are the ones that quietly chip away at the skin barrier, accelerate skin aging, and make skin more sensitive over time.
Whether we’re supporting mature skin, managing sensitivity, or simply undoing the damage of long-term sun exposure in Australia, the goal is always the same: protect collagen, support healthy cell turnover, and keep inflammation at bay. Sitting here in treatment with clients – sometimes even right before they get a microdermabrasion at The Facial Hub – these 7 no-go habits become a foundation for a much healthier skincare routine.
1. They Never Sleep With Makeup On
Dermatologists are mighty particular about sleeping with their makeup on because the combination of sebum, sweat, and pollution, when it mixes with makeup, can wreak havoc on the skin, cause oxidative stress, and years of squeezing can slow down cell turnover. Even micellar water or facial wipes can be a bit too gentle and leave a residue behind – a gentle double cleanse is the only way to get your skin properly clean – something we preach to clients every single day at The Facial Hub.
In Brisbane’s humid climate, where the air is warm and sticky, leaving makeup on overnight can cause dry patches, congestion, and those pesky fine lines. Loads of clients at The Facial Hub in Australia have seen a noticeable improvement after just a few weeks of properly removing makeup at night.
Why it’s off-limits:
Sleeping in makeup just leaves a mess on the skin; it’s like putting your skin in a chemistry lab – barrier breakdown, accelerated aging, the list goes on.
2. They Don’t Pick, Pop, Squeeze Or Dig At Their Skin
No skin specialist worth their salt will ever pick at their own skin. Popping pimples can lead to infection, as it forces bacteria deeper into the skin, disrupts collagen production, irritates the sebum glands, and before you know it, you’re left with a nasty scar and allergic contact dermatitis too. Instead of picking at pimples, dermatologists put their trust in medicated pimple patches, benzoyl peroxide, or retinoic acid to calm down that inflammation.
In the treatment room at The Facial Hub in Brisbane, I’ve lost count of the number of clients who’ve come in with texture issues caused by years of squeezing their face. Your skin is a permanent record; it remembers every injury, even the ones you thought weren’t such a big deal.
Why it’s- off-limits:
Picking can cause major damage – micro-tears, infection, scarring – the list goes on.
3. They Don’t Over-Exfoliate
Whichever method you use – whether it’s a harsh facial scrub, AHAs, a strong toner, or overusing at-home facial devices- dermatologists avoid overdoing the exfoliation. When you over-exfoliate, you weaken the skin barrier, mess with natural cell turnover, and make your skin more reactive.
You see, beauty bloggers often go on and on about these super-complex layered regimens that just look fancy but are actually overwhelming for your skin. At The Facial Hub skin clinic, we’ve seen our fair share of compromised skin barriers, which is thanks to these excessive acids and scrubs.
Why it’s off limits:
Over-exfoliating basically just makes your skin protest – inflammation, impaired barrier – you name it, and it all adds up to premature aging.
4. They Don’t Skip SPF (Ever)
Dermatologists know all too well that UV rays and UVA rays can do some serious damage – accelerating ageing, messing with DNA, and significantly increasing the risk of skin cancer, which is why sunscreen is a must-have, even on the greyest of days. Whether it’s chemical or mineral, daily protection is key for collagen production and maintaining long-term skin resilience.
In the sun-kissed state of Queensland, clients of The Facial Hub in Australia quickly learn that SPF is more than just a product – it’s a daily skincare habit that protects your skin for years to come.
Why it’s off limits:
No protection = faster collagen breakdown, loss of pigmentation control, and a significantly higher risk of cancer.
5. They Don’t Follow Random DIY Skin Hacks
Dermatologists avoid DIY ‘brightening masks’ and other homemade remedies because, let’s be honest, most of them are a recipe for disaster, causing contact dermatitis and long-term barrier disruption. The skin’s pH is super delicate, and those kitchen concoctions rarely get it right.
Professionally formulated skin care products – think vitamin C for brightening, hyaluronic acid for hydration, or micro-encapsulated retinol for smoothing out wrinkles – are the safer, more predictable choice. At The Facial Hub, we see too many compromised skin barriers thanks to well-meaning but misguided kitchen experiments.
Why DIY is such a bad idea:
It’s a recipe for unpredictable pH levels, irritation, burns, and barrier damage.
6. They Don’t Layer Too Many Actives At Once
Healthy skin doesn’t need a 12-step routine, trust us. Dermatologists avoid overloading on potent actives – vitamin C, AHAs, retinoic acid – because it can irritate even the most resilient skin. Overwhelming your skin with too many actives often backfires, causing inflammation or dryness that takes ages to recover from.
In my consultations at The Facial Hub in Brisbane, I’ve found that simplifying a client’s routine can bring about the biggest transformations. A dermatologist’s medicine cabinet is actually pretty minimal – and always carefully curated.
Why layering too many broad-spectrum is such a bad idea:
It destabilises each active and weakens the barrier.
7. They Don’t Ignore Skin Changes — Ever
Dermatologists don’t mess around with new moles, persistent irritation, or unexplained inflammation. Whether it’s a dark spot, a skin tag, or a stubborn patch linked to a chronic skin condition, ignoring symptoms puts off healing.
Many clients at The Facial Hub skin clinic come in after months of hoping something would ‘just go away’. But dermatologists know that early review and full-body checks are a must – especially if you’re living in a high UV environment like Australia.
Why ignoring skin changes is a big no-no:
Early detection is key to protecting your health, collagen, and long-term skin clarity.

| Over-exfoliating | Barrier damage + irritation | Controlled AHAs or micro-encapsulated retinol |
| Skipping SPF | UV damage, cancer risk | Daily broad-spectrum sunscreen |
| DIY skin hacks | Burns + dermatitis | Evidence-based skin care products |
| Layering too many activities | Irritation + inflammation | Simplified, steady routine |
| Ignoring skin changes | Delayed diagnosis | Early check + professional review |
A Reflective Takeaway From My Treatment Chair
Thinking about the 7 things dermatologists can’t or shouldn’t do makes me realise that, when it comes to skin health, it’s not about doing even more, but about getting the basics right. At The Facial Hub, we’ve seen our fair share of dramatic transformations just by getting back to first principles – getting the skin barrier right, changing how people look at the sun, and sorting out the irritants in their lives that they never even knew existed.
If this article has helped you spot one habit that you need to change, you’re going to be one step closer to more relaxed, healthier, and more resilient skin in no time.
FAQ
What’s the real deal on sleeping with makeup on?
It’s really bad news for your skin – you’re essentially locking in all those nasty free radicals, sweat, and the remnants of your last bit of sun cream, and that’s just going to cause more and more harm the longer you do it.
Can popping pimples leave permanent damage?
Unfortunately,y yes, it can cause all sorts of problems, especially with collagen production; it can leave you with deeper inflammation and sometimes even more pigmentation.
Is it normal to over-exfoliatebroad-spectrum?
Actually, we see it all the time – people are way too aggressive with their scrubs or trying to get a quick fix with strong acids, and it’s causing a lot more damage to the skin than they realise.
What kind of SPF is best to slap on every day?
We don’t really mind how you get your protection, as long as you find a broad-spectrum sunscreen you actually enjoy using, whether it’s chemical or mineral, just so long as it covers those UV and UVA rays.
When should I get a thing that’s worrying me looked at?
Honesty – pretty much any time you notice something new, or if something’s still bothering you after a while – get in front of a qualified pro and get a full body check – it’s better to rule out any big problems early on.
