You have the cleanser, the serum, the moisturiser and the SPF. You have watched the videos, read the reviews and stuck with it for weeks. And yet your skin still looks dull, feels irritated or keeps breaking out.

If that sounds familiar, take a breath. It does not mean your skin is a lost cause, and it rarely means you are not trying hard enough. More often, a skincare routine stops working because of a few small mistakes that are very easy to make, especially with so much conflicting advice online.

Here are the five we see most often in clinic, and what to do instead.

1. Doing too much, too often

It is tempting to believe that more products and stronger products mean faster results. In reality, over-cleansing, over-exfoliating and layering too many active ingredients is one of the most common reasons a skincare routine stops working.

Your skin barrier is the outer layer that keeps moisture in and irritants out. When it is healthy, skin looks smooth, calm and comfortable. When it is damaged, you might notice:

• Tightness or a stinging sensation when you apply products
• Redness, flaking or rough patches
• Skin that looks shiny but still feels dry
• Sudden breakouts or sensitivity to products you used to tolerate

A damaged barrier cannot do its job, so even the best products struggle to work. If any of this sounds like you, strip things back to a gentle cleanser, a simple moisturiser and SPF for a couple of weeks and let your skin settle before reintroducing anything.

What to do instead: Use exfoliating acids and strong actives gradually, usually just a few times a week to begin with, and only one new product at a time.

2. Skipping SPF, or not using enough

If there is one step that matters more than any other, it is sun protection. Daily SPF is the most effective thing you can do to prevent premature ageing, pigmentation and uneven tone. Without it, much of the good work from the rest of your routine can be undone.

The common slip-ups are:

• Only wearing SPF on holiday or on sunny days, when UV is present all year round
• Applying too little. Most people use far less than they need
• Forgetting to reapply when outdoors for long periods
• Assuming makeup with SPF is enough on its own

If you are using exfoliating acids or have had a treatment such as a peel or laser, SPF matters even more, as your skin can be more sensitive to the sun.

What to do instead: Choose a broad spectrum SPF 30 or higher that you actually enjoy wearing, and make it the last step of your morning routine every day.

3. Changing products too often

Skin takes time. The skin on your face renews itself over roughly a month, and often longer as we get older. That means most products need at least six to eight weeks of consistent use before you can judge whether they are working.

If you swap your serum every fortnight because you have not seen a miracle, you never give anything a fair chance. Worse, constantly changing things can irritate your skin and make it very hard to tell what is helping and what is not.

What to do instead: Build a simple routine, give it time and only change one thing at a time. If you have used something consistently for two months with no improvement, that is the time to rethink it, ideally with some professional guidance.

4. Using products that do not suit your skin or your concerns

A product that works brilliantly for your friend, or for a social media influencer, might do nothing for you. Or worse, it might make things worse.

Skin type and skin concern are not the same thing. You might have dry skin that is also acne-prone, or oily skin that is also sensitive. Your skin can also change with the seasons, with hormones, with stress and as you age. A routine you built in your 20s may not suit your skin in your 30s, 40s or beyond.

Some other common mismatches include:

• Using a very rich cream on skin that is congested and breakout-prone
• Using harsh, stripping products on dry or mature skin
• Applying products in the wrong order, so lighter products end up sitting under heavier ones and cannot absorb properly
• Chasing the latest trending ingredient rather than treating the concern you actually have

What to do instead: Start with what you want to improve, whether that is pigmentation, breakouts, fine lines, redness or dullness, and choose products designed for that. As a general guide, apply products from thinnest to thickest, finishing with SPF in the morning.

5. Expecting skincare alone to do everything

Good skincare is the foundation, and it makes a real difference. But there are things that products simply cannot do on their own.

Deep-set pigmentation, stubborn acne, acne scarring, lost volume, persistent redness or skin that has become thin and crepey often need more than something you can buy off the shelf. Some of these concerns may also have a medical cause, such as a hormonal imbalance or an underlying skin condition like rosacea or eczema, which no amount of serum will fix.

This is not a sign that your routine has failed. It is just a sign that your skin needs something extra.

What to do instead: Book a skin consultation. A specialist can look at your skin properly, identify what is really going on and build a plan that combines the right at-home routine with in-clinic treatments where needed.
