So, You Think You Have Sensitive Skin? Here's What Experts Are Desperate for You to Know

Let's face it, sensitive skin is a term that gets thrown around a lot. Take a look at virtually any skincare campaign and you'll see labels like "sensitive-skin friendly" or "made for sensitive skin," and that's just the tip of the iceberg.

With the rise of barrier-repair products, more consumers are now prioritising long-term skin health over immediate results. We've moved well past the good old "if it stings, it works" approach, resulting in us ditching harsh actives and intense exfoliators in favour of more gentle yet equally hard-working formulas.

If you’ve ever experienced redness, irritation or inflammation after using a specific product or layering one too many serums, then it’s likely that your skin is experiencing some form of sensitivity, and the truth is, we’re all vulnerable to it.

That’s right; contrary to popular belief, sensitive skin isn’t actually a skin type; it’s a skin condition. This means that sensitivity is something that can occur in anyone’s skin, regardless of what their skin type is, and while some people may experience signs of sensitivity on a daily basis, for others, sensitivity can flare up just a few times a year.

The thing is, our skin can only take so much, no matter how resistant you think it is. After years of cocktailing active skincare ingredients, I learned this the hard way as a teenager when my combined use of exfoliating toners and retinoid serums resulted in a nasty outbreak of perioral dermatitis, a painful inflammatory rash that develops in cases of extreme sensitivity.

Ever since then, I’ve learned to treat my skin as sensitive—using calming ingredients alongside active ones and focusing on strengthening my skin barrier—despite my main skin type being oily and acne-prone.

But what exactly is sensitive skin? What causes sensitive skin? And what can be done to prevent skin sensitivity? Dealing with sensitive skin can be tricky, as you’re constantly wary of trying new things, and it can be hard to pinpoint the exact cause. So to answer your most pressing sensitive-skin questions, we enlisted the help of skincare experts and dermatologists. Here’s everything you need to know about sensitive skin.

What Is Sensitive Skin?

"Sensitive skin can mean different things for different people," says Catriona Maybury, consultant dermatologist and medical lead for Dermatica. "Generally speaking, people often describe skin sensitivity as dryness or irritation, which can be a result of using a particular ingredient in cosmetics." Other potential triggers can include things like our diets, environment, hormones and genetics. "Often, people with sensitive skin either have eczema or a family history of eczema," adds Maybury. "And other conditions, such as rosacea, may also make skin more sensitive."

What Are the Signs of Sensitive Skin?

While symptoms can vary, according to Maybury, the main signs of sensitive skin are itching, dryness, skin that is warm to touch or tingles, and inflammation. "Inflammation can appear as pink or red rashes in lighter skin types, and purple or brown rashes in darker skin types," she explains. For most people, one of the first signs that skin sensitivity is increasing is a tingling or stinging sensation after applying products. If you were to continue applying it or not take any measures to soothe your skin, then redness and inflammation would quickly follow.

What Causes Sensitive Skin?

"There are a great number of factors that can contribute to our skin feeling sensitive," explains Maybury. "An underlying skin condition, such as eczema, can contribute to a tendency to dryness and sensitivity. Internal factors such as genetics and hormonal changes seen in menopause can play a role, along with external factors such as temperature changes, wind and UV light, which can disrupt the skin barrier."

Of course, skincare products are another major potential trigger. "Skincare is becoming more active-led; where active ingredients such as retinoids and antioxidants are being incorporated into skincare products and routines," says Maybury. "These stronger ingredients can cause a degree of skin irritation in anyone as part of their normal mechanism, which can be perceived as skin sensitivity."

This irritation is especially common when first starting to use these products or if they are used too often or at frequent intervals. "Some products can lead to a degree of irritation, particularly with recurrent use and in those with underlying skin conditions," she adds. "Examples include ingredients which can be damaging to the skin barrier such as alcoholic hand sanitisers and drying soaps. This is called an irritant contact dermatitis."

How Should You Treat Sensitive Skin?

If you are experiencing sensitive skin, it’s important to work out if there has been a change in your skin routine or environment first and foremost. "New formulations or active ingredients may lead to some irritation, so it’s really important to keep your routine as simple as possible before you introduce a new ingredient," says Maybury. She recommends introducing new products gradually to see how your skin responds to each one.

"It is common to experience sensitivity during weather and temperature changes," she adds. "Using a thicker, hydrating moisturiser regularly, particularly during the winter will help." Sunscreen is also one of the most effective products in a routine for sensitive skin, since harmful rays of UV light can trigger inflammation, leading to burning and increased sensitivity. "Use of sunscreen before going outdoors is particularly important between April and October in the UK," says Maybury. "There are more UV rays present, which can burn the skin and increase sensitivity."

If getting to the root of your sensitive-skin issues proves particularly difficult, plastic surgeon and founder of 111 Skin and 111 Harley St, Yannis Alexandrides, recommends seeing a dermatologist or aesthetician who can conduct tests to find out the cause. "Find out firstly what is causing your reactive skin and get a specialist to recommend a product and in-clinic protocol to best treat it.

Then, focus on strengthening the skin's barrier function,” he advises. "Most importantly, don’t ignore the issue, never neglect daily sunblock, and don’t experiment with home remedies or over-exfoliation.” If you’re considering a professional in-salon treatment, Alexandrides recommends IPL (intense pulsed light). "This can help take down redness and calm inflamed, reactive skin, especially if someone has been diagnosed with rosacea,” he adds.

What Are the Best Ingredients for Sensitive Skin?

When experiencing sensitivity, it's best to adopt a simple skincare routine, removing active ingredients (like exfoliating acids and retinoids) and focussing on soothing and calming skin with gentle cleansers, cooling mists and nourishing moisturisers. Look out for ingredients that reduce inflammation, such as cica, green tea, and niacinamide, but also ingredients that will help to strengthen your skin, like ceramides and colloidal oatmeal.
