Skincare Mistakes That Could Be Damaging Your Skin

We would all prefer to have healthy skin. Some of us put considerable effort into improving or at least maintaining the skin we have. Yet, we might be harming our skin with bad habits, by using the wrong treatment for our skin type, or by missing some simple cleaning and protection habits that would be of great benefit to our skin. Good skincare need not be expensive. With skincare, as with most things, it is about finding the right combination of healthy habits and quality products, and not about going to extremes.

DermScreen Skin Check Sydney CBD

DermScreen was founded in 2022 by a group of dermatologists who recognised the need for accessible, affordable skincare in Australia. The first goal was to improve melanoma survival rates through early detection of skin cancer. Services soon expanded to include treatments for a range of skin conditions. We presently have Skin Check clinics at Epping, Randwick, Bondi Junction and the Sydney CBD.

Over-Exfoliating and Over-Cleansing

One of the most common mistakes is doing too much. We can understand the enthusiasm; many people believe that frequent washing and exfoliating will keep their skin clean and clear. But these actions often strip away the skin’s natural oils and weaken its protective barrier. So, we can end up with redness, dryness, flakiness, and frequent breakouts. Harsh scrubs and frequent use of chemical exfoliants such as AHAs and BHAs can make the skin increasingly sensitive over time. The better approach is to use a gentle cleanser and limit exfoliation to once or twice a week, depending on skin type. Cleansing twice daily is usually sufficient, with an additional wash only after heavy sweating.

Are People Skipping Sunscreen or Using It Incorrectly?

If we could only impress one piece of skincare advice on everybody, regardless of age, gender, or skin tone, it would be about sun protection. This is especially important in the Australian climate, but it still applies to every country. We need to wear sunscreen, sunglasses, and protective clothing (especially a hat) when outdoors. Many people either skip sunscreen altogether or apply too little. Under-applying will significantly reduce the protection. Even a good quality SPF 30 product may only give SPF 5 protection if it is applied too thinly.

Do We Always Need to Wear Sunscreen?

It is a common misconception that sunscreen is only needed on sunny days. Unfortunately, UVA rays penetrate clouds and glass, meaning damage can occur in overcast weather or while near a window. Daily use of a broad-spectrum SPF 30 sunscreen is essential; even in winter, SPF 30 remains the recommended minimum. Apply this generously using the “two-finger technique” to ensure adequate coverage. Do not rely on makeup with SPF protection. These products provide only partial, inadequate coverage.

Is Lack of Sunlight a Problem?

Of course, we cannot live in the dark. Our bodies manufacture vitamin D when exposed to sunlight. And the sunlight also resets our circadian clock, which helps us sleep. So, we do need some regular sun exposure to stay healthy, and to have healthy skin. People who suffer mood disorders may find that sensible sun exposure helps improve symptoms of low mood and anxiety. We recommend early morning sun exposure for about 10 to 30 minutes. This is usually enough for good health. Supplementation with vitamin D is also a good option.

Using Too Many Active Ingredients

Modern skincare routines may include multiple serums and treatments. But combining too many active ingredients can do more harm than good. Ingredients such as retinol, vitamin C, and exfoliating acids can irritate the skin when layered incorrectly. This can lead to a compromised skin barrier, burning, peeling, and persistent inflammation. In many cases, people mistake this irritation for the product “working,” when it is actually causing damage. A simplified routine is usually more effective. Focusing on the basics (cleanser, moisturiser, targeted treatment, and sunscreen) allows the skin to function properly without being overwhelmed.

Not Moisturising Oily or Acne-Prone Skin?

A common misconception is that oily skin does not need moisturiser. Skipping this step often leads to the opposite effect. When the skin becomes dehydrated, it produces more oil to compensate, which can trigger further breakouts. By using a lightweight, non-comedogenic moisturiser, we can maintain balance and support the skin barrier. Hydrated skin is less likely to become irritated or inflamed.

Is Soap Bad for Skin on the Face?

Most soap is too harsh for the skin on our face. It will strip away the natural oil and either leave the facial skin dry or cause the skin to overcompensate and produce more oil. This was one of the main reasons why earlier generations developed premature wrinkles. Use warm water and a cleanser designed for the face. Then use a moisturiser designed for your skin type.

What Are Some Poor Hygiene Habits?

Many skincare issues are linked to everyday hygiene habits that are often overlooked.

• Dirty pillowcases, towels, and makeup brushes can harbour bacteria, oil, and dead skin cells. Reintroducing these onto freshly cleansed skin can lead to recurring acne and irritation. Simple changes – fresh pillowcases every few days, regularly washed brushes, and clean towels – can make a significant difference.
• Mobile phones are another common source of bacteria. Simply cleaning the phone with a sanitising wipe every 2 or 3 days helps prevent issues.
• Sleeping in makeup is a very damaging habit. Makeup can clog pores, trap dirt, and prevent the skin from properly renewing itself during sleep. This can lead to breakouts, irritation, and accelerated ageing. Even non-comedogenic products can cause problems if left on for extended periods. Always remove makeup before bed, even if it means using a simple makeup remover when tired.
• We might be tempted to pick acne or scrub our skin. But this almost always makes the acne worse. Scrubbing irritates the skin, while squeezing pimples can push bacteria deeper, increasing inflammation and the risk of scarring. A gentle approach is more effective. Acne treatments should be applied consistently across affected areas, not just on visible blemishes. Avoiding physical irritation allows the skin to heal properly.
• ·Hot showers can strip the skin of its natural oils, leading to dryness and irritation. While it may feel comfortable, hot water can weaken the skin barrier. Stick with warm water instead. Finishing with cooler water can help reduce irritation and improve skin comfort.

What Are Some Good Skin Habits?

Many good habits are quite simple.

• Wear a broad-brimmed hat and UV-protective sunglasses when outdoors.
• Wear sunscreen on the face and on any exposed skin when outdoors.
• Drink plenty of water.
• Get some sunlight in the early morning, when the light is less intense.
• Eat a healthy diet and avoid junk food, especially fried food.
• Talk to a dermatologist about the right skin products for your skin type.

Are There Problems with Using Inappropriate Products?

Not all skincare products suit every skin type. Using a cleanser that is too harsh or products that clog pores can worsen existing issues. Examples include foaming cleansers, which may be too drying for sensitive or dehydrated skin, while heavy or comedogenic products can trigger breakouts in oily skin. It is essential to understand your skin type. In some cases, what appears to be dry skin may actually be a damaged skin barrier caused by overuse of active products.

Quitting Too Soon

Skincare takes time. Many people expect immediate results and stop using products after only a week or two. Skin cell turnover typically takes around 28 days, and improvements in conditions like acne or pigmentation may take several months. Consistency is key. Most treatments should be given at least 6 to 8 weeks before evaluating their effectiveness, unless there is significant irritation.

Neglecting Areas Beyond the Face

While our face might be the most noticeable part of our appearance, skincare does not stop at the jawline. The neck, chest, and hands are also prone to ageing and sun damage, all the more so as we tend to overlook these areas.
