Skincare Mistakes

We have all been guilty of climbing into bed without taking our makeup off after a night out or long day at work.

Common Skincare Mistakes That Can Harm Your Skin (And How to Avoid Them)

We all want healthy, glowing skin, but sometimes, in our busy lives, we fall into skincare habits that may be doing more harm than good. From skipping makeup removal at night to using the wrong products for your skin type, there are several common mistakes many of us make. In this post, I’ll walk you through some of these mistakes and how you can avoid them to keep your skin looking its best.

1. Sleeping with Makeup On

We’ve all been guilty of falling into bed without removing our makeup after a long day, but this can do serious damage to your skin. When makeup is left on overnight, it can clog pores, stretch them, and lead to inflammation, which can cause spots and irritation.

Why it matters:
Makeup, combined with the pollution, smoke, and toxins we encounter throughout the day, creates an invisible layer of chemicals on your skin. These can lead to free radical damage, which speeds up the breakdown of collagen and accelerates skin aging. Plus, leaving makeup on overnight means it gets stuck in your pores, making them larger and less elastic over time.

What to do:
Always make sure to cleanse your skin thoroughly before bed to remove makeup, dirt, and pollutants. This helps your skin repair and regenerate overnight, keeping it fresh and clear.

2. Not Wearing Sunscreen Daily

Even in cooler climates like the UK, we’re still exposed to UV radiation every day. It may seem harmless when the sun isn't shining, but UV rays are a major cause of premature aging.

Why it matters:
UV rays cause free radical damage to your skin, triggering a chain reaction that damages skin cells and breaks down collagen. This can lead to wrinkles, sagging, and other signs of premature aging.

What to do:
Make sunscreen a daily habit. Choose a broad-spectrum sunscreen (which protects against both UVA and UVB rays) with at least SPF 30, though SPF 50 is ideal. Don’t rely on sunscreen combined with moisturisers or makeup—use a separate sunscreen product to ensure proper protection.

3. Using Face Wipes Instead of Proper Cleansing

Face wipes are quick and convenient, but they aren’t the best option for properly cleansing your skin.

Why it matters:
Face wipes may seem effective, but they often just smear dirt, oil, and makeup around your face without fully removing them. Plus, they can leave a residue that may irritate your skin or prevent your skincare products from being properly absorbed.

What to do:
Use a gentle cleanser and lukewarm water to properly wash your face. A good cleanser will remove dirt, makeup, and pollution, leaving your skin clean and ready to absorb moisturizers and serums.

4. Using Too Much Product

It’s easy to think that slathering on more product will speed up results, but over-applying skincare can cause problems.

Why it matters:
Applying too much of a product can clog pores and lead to irritation. Some ingredients can also build up on the skin, leading to breakouts or inflammation.

What to do:
A little goes a long way. A pea-sized amount of most products is usually enough to cover your face. Stick to the recommended amount to avoid overloading your skin.

5. Not Moisturising Oily Skin

If you have oily skin, you might think skipping moisturiser is a good way to control oil, but this is a mistake.

Why it matters:
Not moisturising oily skin can actually make it worse. When your skin is deprived of moisture, it goes into “overdrive” and produces even more oil to compensate.

What to do:
Use an oil-free, lightweight moisturiser to help balance your skin’s hydration levels. Moisturizers help to hydrate the skin without adding extra oil, keeping your skin healthy and balanced.

6. Not Cleaning Your Makeup Brushes

You wouldn’t wear the same clothes every day without washing them, so why would you use dirty makeup brushes on your skin?

Why it matters:
Makeup brushes can quickly become a breeding ground for bacteria, dirt, and oil. When you apply makeup with unclean brushes, you’re transferring these germs onto your skin, which can lead to breakouts and irritation.

What to do:
Clean your makeup brushes regularly with a brush cleanser or mild soap. This will help prevent bacteria build-up and ensure your makeup goes on smoothly and evenly.

7. Over-Exfoliating

Exfoliation is important for keeping your skin smooth and bright, but overdoing it can cause more harm than good.

Why it matters:
Exfoliating too frequently or using multiple exfoliating products can strip your skin of its protective barrier, causing irritation, sensitivity, and even increased breakouts.

What to do:
Stick to exfoliating no more than 2-3 times a week. Choose one exfoliating method—whether it’s a scrub, chemical exfoliant (like AHAs), or a physical treatment—and give your skin time to recover between uses.

8. Using the Wrong Products for Your Skin Type

Just because a product worked wonders for your friend doesn’t mean it’s right for you. Understanding your skin type is key to choosing the right products.

Why it matters:
Using the wrong products can lead to irritation, dryness, or breakouts. For example, a rich cream that works well for dry skin can leave oily skin feeling greasy and clogged, while a product that’s too harsh for sensitive skin can cause redness and irritation.

What to do:
Take the time to understand your skin’s needs. Consider getting a skin consultation to better understand your skin type and choose products tailored to your specific concerns.

9. Not Getting Enough Sleep

We all know that sleep is essential for our overall health, but it’s also vital for healthy, glowing skin.

Why it matters:
During sleep, your body repairs and regenerates skin cells. Lack of sleep can increase cortisol (the stress hormone), which can lead to skin flare-ups, irritation, and even premature aging.

What to do:
Aim for 7-9 hours of quality sleep each night. Make sleep a priority to give your skin the time it needs to heal and rejuvenate.

10. Poor Diet

What you eat affects your skin just as much as the products you apply.

Why it matters:
A diet high in sugar, processed foods, and dairy can contribute to premature aging and acne flare-ups. On the other hand, a diet rich in fruits, vegetables, and antioxidants can help protect your skin from damage and keep it looking youthful.

What to do:
Eat a balanced diet full of fresh fruits, vegetables, whole grains, and lean protein. Foods rich in vitamin C and vitamin E are especially great for skin health, as they help repair skin cells and fight free radical damage.

Final Thoughts

Healthy skin is a result of good habits, consistency, and a little bit of knowledge about what your skin needs. By avoiding these common skincare mistakes and adopting better habits, you can maintain healthy, radiant skin for years to come. If you're unsure about your skincare routine or need personalized advice, don't hesitate to seek guidance from a skincare professional who can help you develop a regimen tailored to your skin type and goals.
