Most people who walk into a dermatology clinic are not neglecting their skin. Quite the opposite. They are usually doing too much, doing the right things in the wrong order, or following advice that was never meant for their skin type or climate. At our dermatology clinic in JVC, Dubai, we see the same handful of habits behind breakouts, redness, dark patches and sensitivity week after week.
The good news is that almost all of them are fixable. Below are the seven skincare mistakes we see most often, why they cause problems, and what our doctors recommend doing instead. If you recognise yourself in more than one, you are in very good company.
Quick answer
The most common skincare mistakes dermatologists see are over-exfoliating, not using enough sunscreen, picking at spots, using strong products without medical guidance, skipping moisturiser because the skin feels oily, switching products too quickly, and ignoring skin changes that need a proper diagnosis.
1. Over-Exfoliating and Stacking Too Many Actives
This is the number one issue we see in patients under 35. A typical routine might include a glycolic acid toner, a salicylic acid serum, a retinol at night and a scrub twice a week. Each product is fine on its own. Together, they strip the outer layer of the skin faster than it can repair itself.
Your outer skin layer, the stratum corneum, works like a brick wall. The skin cells are the bricks and natural fats such as ceramides are the mortar. When you exfoliate too often, you knock bricks out before new ones are ready. Moisture escapes, irritants get in, and the skin becomes red, tight, shiny yet dry, and prone to stinging when you apply even a gentle cream.
What our dermatologists see
- Burning or stinging with products that never used to bother you
- A tight, “plastic” shine on the cheeks and forehead
- Sudden small bumps or breakouts that look like acne but do not respond to acne treatment
What to do instead
Pick one exfoliating active and use it two or three nights a week to start. If you use a retinoid, do not use an acid on the same night. If your skin is already irritated, stop all actives for one to two weeks and use only a gentle cleanser, a ceramide moisturiser and sunscreen. The American Academy of Dermatology recommends a simple, consistent routine over a complicated one, and in our experience the calmest skin usually belongs to the patients using the fewest products.
2. Using Too Little Sunscreen (or Only on Sunny Days)
Almost every patient tells us they wear sunscreen. Far fewer apply enough of it, and even fewer reapply. In the UAE, where UV levels stay high for most of the year, this single habit has a bigger effect on pigmentation, early lines and uneven tone than any serum on the market.
Most people apply around a quarter to half of the amount used in lab testing, which means the SPF on the label is not the protection they actually get. UVA rays also pass through car windows and glass, so a daily commute along Sheikh Zayed Road still counts as sun exposure.
What to do instead
- Use a broad spectrum sunscreen of SPF 30 or higher every morning, whatever the weather
- Apply roughly two finger lengths for the face and neck
- Reapply every two hours when outdoors, and after swimming or heavy sweating
- If you have melasma or pigmentation, ask about a tinted sunscreen with iron oxides, which also helps block visible light
The Skin Cancer Foundation has a clear guide to choosing and applying sunscreen correctly. If you already have sun spots or uneven tone, our team can build a plan that combines sun protection with suitable treatments from our range of skin and laser services.
3. Picking, Squeezing and Popping Spots
We understand the urge. A spot appears before an important meeting and you want it gone now. But squeezing pushes bacteria and inflammation deeper into the skin, and the mark it leaves often lasts far longer than the spot itself would have.
In medium and deeper skin tones, which make up a large part of our patients in Dubai, picking commonly leads to post-inflammatory hyperpigmentation (PIH). These are the brown or dark marks that can take three to twelve months to fade. Repeated picking can also cause permanent pitted or rolling scars that need procedures to improve.
What to do instead
Apply a benzoyl peroxide or salicylic acid spot treatment, or use a hydrocolloid patch so you physically cannot touch it. For a painful, deep cyst before an event, a dermatologist can sometimes inject a small dose of medication that settles it within a day or two. If you are getting breakouts regularly, that is a sign your acne needs proper treatment rather than spot fixes.
4. Using Strong Products Without Medical Guidance
This mistake worries our doctors the most, because the damage can be long lasting. We regularly see patients who have used a steroid cream for months to “calm” redness or lighten their skin, or who bought a whitening cream online or abroad with no clear ingredient list.
Topical steroids are useful medicines when prescribed for the right condition and the right length of time. Used on the face without supervision, they can thin the skin, cause visible blood vessels, trigger rosacea-like rashes and create a rebound flare when you stop. Some unregulated lightening creams have also been found to contain mercury, which the World Health Organization warns can damage the kidneys and nervous system.
What to do instead
- Only use steroid, hydroquinone or prescription retinoid creams under the guidance of a licensed doctor
- Avoid products with no ingredient list, or ones that promise dramatic lightening in days
- If you have already been using a steroid cream for a long time, do not stop suddenly without advice, as the rebound can be severe
In the UAE, you can check whether a clinic and its doctors are licensed through the Dubai Health Authority. Every treatment at Sasha Aesthetic Clinic is planned by a DHA-licensed doctor, which you can read more about on our About Us page.
5. Skipping Moisturiser Because Your Skin Is Oily
Many patients with oily or acne-prone skin avoid moisturiser completely, worried it will clog pores. What usually happens is the opposite. Dehydrated skin can respond by producing more oil, and acne treatments like retinoids and benzoyl peroxide become far more irritating without a moisturiser to support them.
Dubai adds its own twist. Long hours in air conditioning pull moisture from the skin, then stepping out into humid heat makes it feel greasy. The result is skin that is oily on the surface and dehydrated underneath, which is one of the most common combinations we see in clinic.
What to do instead
Choose a light, oil-free gel or lotion labelled non-comedogenic. Look for ingredients like glycerin, hyaluronic acid, niacinamide and ceramides. Apply it on damp skin after cleansing, and keep showers warm rather than hot, since very hot water strips natural oils from both the face and body.
6. Switching Products Too Quickly
Social media makes it easy to buy a new serum every week. The problem is that skin renews itself roughly every four to six weeks, and most active ingredients need eight to twelve weeks to show real results. When a routine changes constantly, it becomes impossible to know what is helping and what is causing a reaction.
Introducing several new products at once is a related mistake. If your skin reacts, you have no idea which one was responsible, so you often end up abandoning a product that was actually right for you.
What to do instead
- Introduce one new product at a time, with at least two weeks between additions
- Patch test first by applying a small amount behind the ear or on the inner arm for a few days
- Give a product at least two to three months before judging it, unless it causes irritation
- Take a photo in the same light every two weeks so you can see gradual change
7. Self-Diagnosing and Ignoring Changes That Need a Doctor
A lot of skin conditions look alike. We often meet patients who have treated “acne” for a year when it was actually rosacea, or used harsh peels on “sun spots” that turned out to be melasma, which can get darker with aggressive treatment. The NHS guide to rosacea and the AAD overview of melasma show how different these conditions are, even though they can look similar in the mirror.
The most important changes to never ignore are changes in moles. Dermatologists use the ABCDE rule: Asymmetry, irregular Border, uneven Colour, Diameter larger than about 6 mm, and Evolving shape, size or colour. The American Academy of Dermatology’s ABCDE guide explains each sign clearly.
See a dermatologist if you notice
- A mole or spot that is new, changing, bleeding or itching
- Acne that leaves marks or scars, or has not improved after three months of over-the-counter care
- Persistent redness, flushing or visible veins on the cheeks and nose
- Dark patches on the cheeks, forehead or upper lip that keep returning
- Dry, itchy or flaky patches that do not settle with moisturiser
At a Glance: The Mistake and the Fix
Common Mistake | What It Can Cause | Dermatologist Fix |
Over-exfoliating | Barrier damage, stinging, redness | One active, 2 to 3 nights a week |
Too little sunscreen | Pigmentation, early ageing | SPF 30+, two finger lengths, reapply |
Picking spots | Dark marks and scarring | Spot treatment or hydrocolloid patch |
Unsupervised strong creams | Thin skin, rebound flares | Prescription products only with a doctor |
Skipping moisturiser | More oil, more irritation | Light, non-comedogenic moisturiser |
Switching products fast | Reactions, no clear results | One change at a time, 8 to 12 weeks |
Self-diagnosing | Wrong treatment, missed warning signs | Professional skin assessment |
What We Tell Patients on Their First Visit
When a new patient brings in a bag of products, our first step is usually to take things away rather than add more. A routine built on a gentle cleanser, a moisturiser that suits the skin type, daily sunscreen and one targeted treatment solves more problems than people expect. Once the skin barrier is calm, we can safely add medical treatments for acne, pigmentation or ageing where they are genuinely needed.
That is the approach behind our dermatology services at Circle Mall, JVC. Each plan starts with a consultation and a proper look at your skin, not a sales list. As part of Sasha Group, which has cared for skin and beauty in Dubai since 1994, our focus is on steady, natural-looking results that last. You can learn more about the clinic on our homepage.
Frequently Asked Questions
Over-exfoliating is the mistake dermatologists see most often, especially when people combine acids, retinoids and scrubs. It weakens the skin barrier and causes redness, stinging and breakouts.
Most people do well with four: a gentle cleanser, a moisturiser, a broad spectrum sunscreen in the morning and one targeted treatment at night, such as a retinoid or an acne product.
Common signs include stinging when you apply products, tightness after cleansing, flaking, a shiny but dry look and sudden sensitivity to products you used before without problems.
If you sit near windows or drive a lot, yes. UVA rays pass through glass and contribute to pigmentation and skin ageing. Applying sunscreen every morning is the simplest way to stay protected.
Book a consultation if acne is leaving marks, if a treatment has not helped after about three months, if you have ongoing redness or dark patches, or if a mole changes in any way.
