The Blog Skin Age Calculator

Published 5 January 2026
Updated 22 January 2026

Find out if your skin is older — or younger — than your years.

How old is your skin, really? While your passport might say one thing, your skin could be telling a very different story. Factors like sun exposure, diet, exercise, skincare habits, and even lifestyle choices all play a role in how youthful, or prematurely aged, your skin appears.

That’s why the experts at Contour Clinics have created our Skin Age Calculator: a simple, science-based tool that looks beyond birthdays to reveal your true skin age.

Consider it a playful check-in that shows which habits are helping your skin shine, and which might be fast-tracking the clock.

The good news is that no matter what number you get, there are plenty of ways to support your skin’s health and vitality. Simple changes, like protecting yourself from the sun, eating a nutrient-rich diet, staying active, and following a consistent skincare routine, can help your skin look and feel its best for years to come.

Now that you’ve used the Skin Age Calculator, you have a snapshot of your skin’s current state.

But numbers alone don’t tell the full story. Your results reflect the combined impact of lifestyle choices, skincare habits, and environmental factors over time.

To help you understand what’s driving your score, and what you can do to support healthier, more resilient skin, we’ve created this quick, science-backed report. Think of it as your personalised guide to ageing well, with practical tips you can start using today.

Lifestyle Habits That Affect Skin Ageing

Your everyday choices play a big role in how your skin ages over time. Smoking, for example, can deepen lines around the eyes and mouth, thin lips, and reduce elasticity. In identical twin studies, the sibling with a longer smoking history often shows more wrinkles, sagging, and facial volume loss than the non-smoker. This highlights how smoking accelerates skin ageing independently of genetics. The good news is that quitting can gradually improve hydration, elasticity, and overall skin appearance over time.

Alcohol can also affect how your skin looks. Drinking heavily, around eight or more drinks a week, has been linked to under-eye puffiness, deeper forehead lines, and a loss of midface volume, while moderate drinking usually has much smaller effects.

Sleep and stress play a big role in skin health, too. Not getting enough sleep or going to bed late can leave your skin dry, less firm, and slower to repair itself. Chronic stress can also break down collagen and elastin, leading to fine lines and wrinkles. Making sleep and stress management a priority helps your skin recover and keeps it looking radiant.

Diet and exercise support your skin from the inside out. Eating nutrient-rich foods, like colourful fruits and veggies, oily fish, nuts, and whole grains, gives your skin the antioxidants and amino acids it needs to repair and stay elastic. Staying active boosts circulation and hydration, helping your skin maintain a healthy, youthful appearance.

How To Slow Skin Ageing With Skincare

Targeted skincare routines can directly influence how your skin ages. Retinoids, derivatives of vitamin A, are highly effective in stimulating collagen production, smoothing texture, and reducing early lines. Early use, typically from the late 20s to early 30s, can help prevent the development of fine lines and uneven tone. Because retinoids can cause irritation initially, they should be introduced gradually and always used alongside daily sunscreen.

Antioxidants such as vitamin C, vitamin E, niacinamide, and plant polyphenols protect the skin from oxidative stress caused by UV exposure, pollution, and other environmental factors. This helps maintain elasticity, reduce fine lines, and support the skin’s natural repair processes. Antioxidants can be applied topically or consumed through diet, providing a dual layer of protection.

Moisturisers also play a vital role in maintaining skin health. They lock in hydration, reinforce the skin barrier, and prevent dryness, which can exacerbate fine lines and reduce elasticity. Using a moisturiser daily, typically in the morning and before bed, enhances the skin’s resilience against environmental stressors.

By combining these elements, retinoids, antioxidants, moisturisers and skin treatments, you can maintain skin health, repair minor damage, and slow the visible signs of ageing. Consistency is key, and even small, sustained improvements in your skincare routine can have a noticeable impact over time.

How Sun Exposure Affects Skin Ageing

Sun exposure is the single biggest factor when it comes to visible skin ageing. UV rays penetrate deep into your skin, breaking down collagen and elastin, which can lead to wrinkles, fine lines, and changes in pigmentation. Even the occasional blistering sunburn or intentional tanning session can speed up ageing, making your skin look older than it really is. That’s why using a broad-spectrum sunscreen every day, even on cloudy days or when you’re mostly indoors, is so important. SPF 30 or higher, applied to all exposed areas and reapplied every two hours when you’re outside, offers the best protection.

Your skin type also affects how sensitive you are to UV damage. Fairer skin types (Fitzpatrick 1-2) are the most vulnerable, while medium to darker skin types (3-5) have more natural protection, but everyone is still at risk of wrinkles and pigmentation. If you have fair skin, it’s especially important to be extra careful during peak UV hours (10 am–3 pm), wearing protective clothing and a hat in addition to your sunscreen.

By consistently combining daily SPF, targeted actives like retinoids and antioxidants, and supportive moisturisation, you create an integrated approach that slows visible ageing, helps maintain elasticity, and keeps your skin looking healthy over time.
