Your questions on aftersun answered
What is the best aftersun?
Overall, there is a product for everybody in this round-up. For something simple, nourishing and easy to use, Bioderma is a great option as the best aftersun I tested. If you’re on a budget, Garnier’s Ambre Solaire hydrating after sun is soothing and absorbs easily. La Roche-Posay’s athelios post-UV exposure aftersun lotion contains a combination of skin calming ingredients, but with no fragrance or drying alcohols, is the best aftersun I tested for sensitive skin.
How I tested aftersun
Although I’d never get a sunburn in the name of journalism, I suffered from a burn after a day at a local lido. As a result, I could test these formulas effectively. I also used these aftersuns in place of body lotion, post-shower, during a heatwave, to test the the following criteria:
- Skin-feel: I wanted aftersun that could soothe, cool and hydrate; these were some of the first skin effects I looked for. I also made a note of how lightweight or heavy the formula was, and whether it absorbed quickly or left any residual greasiness.
- Formula: I factored in skin suitability, including for sensitive skin types, and how quickly it soothed my angry skin. I also noted any key nourishing ingredients and their benefits.
- Scent: This can make or break a skincare product for some people, as some have sensitivities to fragrance and others straightforwardly dislike fragrance. I made a note of not just the fragrance or lack thereof, if it was fragrance-free, but also the scent’s potency.
- Value for money: I considered whether the amount of product, the quality of the formula and its effects were reflected in the price.
How to avoid getting sunburnt
The first step to avoiding sunburn is to keep out of direct sunlight during the hottest part of the day, which is 11am to 3pm in the UK, according to the NHS. SPF is crucial over your entire face and body, and be sure to cover up with suitable clothing and sunglasses.
How to ease sunburn
According to the NHS, the first thing to do when you start to spot sunburn is to get out of the sun. If that’s not possible, cover any areas of skin with a piece of thick fabric, such as a towel. Cool down skin with a cold shower, bath or damp towel, but be mindful not to let young children or babies get too cold. As well as applying aftersun creams and sprays, staying hydrated is also key. “Drink water to support hydration and avoid further sun exposure,” advises Dr Jamil.
If symptoms go beyond mild redness or discomfort, it’s important to get medical advice. Dr Jamil recommends seeking help if you experience severe redness or blistering, fever, chills, nausea, swelling, signs of infection or any unusual or persistent skin changes.
What not to use on sunburn
Although it may be tempting, the NHS advises against using ice or icepacks on sunburn; always opt for cool water instead. According to the NHS, other no-go remedies include petroleum jelly (Vaseline), and you should avoid tight-fitting clothes. Do not pop blisters and do not peel or scratch burnt skin.
What actually happens to your skin after sun exposure?
Even without visible sunburn, UV rays can cause damage beneath the surface of the skin. “You cannot always see the damage the sun is doing to your skin,” says Dr Jamil, noting that exposure to UVA and UVB rays can lead to dryness, reduced elasticity and pigmentation changes over time.
Can aftersun repair sun damage?
In short, no. “Aftersun cannot actually repair any sun damage,” says Dr Jamil. Instead, these products are designed to soothe irritation and replenish lost moisture, helping to support the skin barrier after exposure.
“Some UV exposure can still get through, even if you have reapplied SPF throughout the day,” explains Dr Jamil. Aftersun helps rehydrate the skin and replace moisture lost during sun exposure, even if you don’t have any visible sunburn.
Can you use aftersun on your face?
You can, but it depends on the formula. “Aftersun can be used for the face and body, however sometimes they can be too fragranced for your face and can cause irritation,” says Dr Jamil. If you have sensitive skin, it’s often better to opt for a face-specific product.
Can aftersun help prolong a tan?
To a degree. “Hydrated skin sheds more slowly, so technically using aftersun can prolong a tan,” says Dr Jamil, though she says that maintaining hydration in general will have a similar effect.
