You got through your teens without too much trouble. Maybe you even felt smug about it. Then you hit your 30s or 40s, and suddenly you are standing in front of the mirror with a deep, painful spot along your jaw, wondering what on earth you did to deserve it.

First things first: you are not alone, and it is not your fault. Adult acne is far more common than most people realise, and it is one of the most frequent reasons our clients book a consultation. It is also very treatable once you understand what is driving it.

Here is what is actually going on with acne in your 30s and 40s, and what you can do about it.

Is adult acne normal?

Yes. Acne is not just a teenage problem. Many adults, and women in particular, deal with breakouts well into their 40s and beyond. Some people have had acne since their teens and never grown out of it. Others, like you might be, find it appears for the first time as an adult, which can feel especially frustrating and confusing.

Whichever group you fall into, adult acne tends to behave differently from teenage acne. It is more likely to sit around the lower face, jawline, chin and neck. It often shows up as deep, tender lumps rather than lots of small blackheads. And it can be stubborn, coming back in the same places month after month.

That pattern is a big clue about the cause.

What causes acne in your 30s and 40s?

There is rarely one single answer. Adult acne usually comes from a mix of factors, and working out which ones apply to you is the key to treating it properly.

Hormonal changes

Hormonal acne is the most common culprit in adult skin. Oil glands are sensitive to hormones, particularly androgens, and when your hormone levels shift, those glands can produce more oil and become more easily blocked and inflamed.

In your 30s and 40s, hormones move around a lot. Common triggers include:

• Your monthly cycle, with breakouts often appearing in the week or so before a period
• Coming off or switching hormonal contraception
• Pregnancy and the months after having a baby
• Perimenopause, which can begin in your 40s and sometimes earlier
• Polycystic ovary syndrome (PCOS), which can cause persistent breakouts alongside other symptoms

If your spots are deep, sore and clustered around the jaw and chin, hormones are a very likely part of the picture.

Stress

We all know stress feels awful, but it can show up on your skin too. When you are under pressure, your body releases more cortisol, which can encourage your oil glands to work harder. Adult life tends to come with plenty of stress, from work to family to everything in between, so it is no surprise that skin can suffer.

Skincare and makeup

Sometimes the thing causing the problem is sitting on your bathroom shelf. Heavy creams, rich oils and some makeup products can clog pores. On the other hand, over-cleansing and harsh scrubs can strip the skin and damage its barrier, which often makes breakouts worse rather than better.

If you have started layering on lots of anti-ageing products to deal with early lines, it is worth asking whether any of them could be contributing.

Genetics

If your parents or siblings had acne as adults, you are more likely to as well. You cannot change your genes, but knowing this can take away some of the guilt. You did not cause this by doing something wrong.

Other triggers

Certain medications, hair and body products that touch the skin, and friction from things like phone screens, face masks or helmet straps can all play a part. Diet may also have an influence for some people, although it is rarely the whole story, and it is not worth cutting out entire food groups without good reason.

Why does adult acne feel so different?

Teenage skin is oily all over. Adult skin is a different beast. By your 30s and 40s, your skin is renewing itself more slowly, so dead skin cells can hang around and block pores for longer. At the same time, you may be dealing with dryness, early signs of aging and sensitivity.

This is why so many adults feel stuck. The products that worked at 16 can be far too harsh now, yet gentle products may not be strong enough to help. Treating acne while also looking after mature skin takes a more thoughtful approach.

How to treat adult acne

The right treatment depends on what is causing your breakouts, how severe they are and what your skin can tolerate. Here is what we would usually consider.

Start with a proper skin assessment

Before you buy another product, it helps to have an expert look at your skin and talk through your history. A consultation with one of our dermatology specialists can identify whether your acne is hormonal, product-related or a mixture, and rule out other skin conditions that can look similar, such as rosacea.

Dermatology consultations are available at all three of our clinics in Beckenham, Orpington and Sevenoaks.

A simple, gentle routine

For most people, the basics matter more than a long list of products:

• A gentle cleanser, used morning and night
• A lightweight, non-comedogenic moisturiser, because acne-prone skin still needs hydration
• Daily SPF, which also helps prevent acne marks from darkening
• Targeted ingredients suited to your skin, introduced slowly

Less really is more. Constantly changing products is one of the most common mistakes we see.

Medical treatments

For persistent or moderate to severe acne, skincare alone is often not enough. Your specialist may discuss prescription options with you depending on your type of acne, your health and your goals. If your acne looks hormonal, it may also be worth speaking to your GP about whether a hormonal cause needs investigating.

Clinic treatments that can help

Alongside a medical plan, certain in-clinic treatments can support clearer, healthier skin:

• Chemical peels help to unclog pores, smooth rough texture and fade marks left by old breakouts. Available at all three clinics.
• Intra-lesional steroid injections can calm large, painful cysts quickly and reduce the risk of scarring. Available at all three clinics.
• Skinpen microneedling stimulates the skin's natural repair process and is well known for improving the look of acne scarring over a course of treatments. Available at all three clinics.
• Hydrafacial and LED light facials can deep cleanse congested skin and support healing. Available at Beckenham and Sevenoaks.

Your specialist will recommend what suits your skin and when. Some treatments are best saved for when active breakouts are calm, which is another reason a proper consultation matters.
