The best aftersuns work to nourish and rehydrate parched skin, as well as providing a dose of cooling relief if you've been caught out by sunny weather. A summer staple, they work alongside the best facial sunscreens and bodycare suncreams to protect our skin in hot weather.

“Sun damage caused by UVA radiation is practically irreversible as it damages the skin at a DNA level, which is hard to undo,” says Dr Catharine Denning, aesthetic doctor and the founder of the Marylebone Skin clinic. If, however, you do experience a degree of sunburn (we’ve all been there), it’s important to support the skin in healing itself. This is where aftersun lotion comes in, an essential when it comes to how to treat sunburn easily.

“A good aftersun lotion can calm and soothe sun-exposed skin,” says Dr Sophie Shotter, aesthetic doctor and the founder of the Illuminate Skin Clinic. “Regardless of whether you’ve burnt your skin or not, aftersun will help to restore a healthy moisture balance,” she continues. Our edit of the best aftersun lotions, tried, tested and reviewed by our team of experienced beauty journalists will help you find the right product for you.

The best aftersun lotions, reviewed by our beauty team  

Whether you’re looking for a reliable and affordable aftersun, a multitasker that replaces self-tanner or mosquito repellent, or something that’s more of a first-aid essential for sunburn than a post-sun moisturiser, these are all the best aftersun lotions to keep handy this summer.

How to pick the best aftersun lotion

There are countless aftersun lotions available on the market – which can make finding ‘the one’ a difficult task. Overall, most formulas do work. The difference being is that some are laced with extra skincare ingredients. Here are a couple of things to consider:

  • Texture: As with the best face moisturiser, aftersun comes in a variety of textures – from lightweight lotions to heavier balms. Consider your texture preference before choosing an aftersun product.
  • Ingredients: Look out for antioxidant-rich ingredients like Aloe vera and vitamin E as they can help prevent further skin damage. “Ceramides are also good at soothing inflamed skin,” says Dr Denning. Hydrating ingredients, such as hyaluronic acid and glycerin, also have the benefit of helping your skin hang onto a natural glow, if you're interested in how to make a tan last longer. Avoid any aftersun lotions that contain alcohol as it can dehydrate skin further.

Does aftersun lotion really work?

“There’s no quick fix to heal sunburn,” confirms Dr Denning. However, there are things that can help.” Enter: aftersun. To understand how aftersun lotion works, Dr Denning gives us a quick science recap: “Heat from the sun causes damage to the skin by irradiating it, which leads to the skin heating up, causing water loss, dehydration and inflammation."

Aftersun is specifically designed to support the skin's healing process. “It’s lightweight, meaning it allows heat to leave the skin and has a high water content to replace water loss in the skin," Dr Denning continues. "Plus, aftersun also contains soothing, anti-inflammatory antiseptic ingredients such as aloe, bisabolol, and allantoin."

Is aftersun or moisturiser better for sunburn?

According to Dr Denning, “aftersun is preferable to normal moisturiser, however any moisturiser is better than none.” Dr Shotter notes that it depends on the formulation. “If you have a good, gentle, soothing moisturiser that contains Aloe vera, then it doesn’t need to be targeted at sunburn," she says. "However, if reading an ingredients list is tricky, looking for a product marketed as ‘aftersun’ can be helpful.”

What should you not put on sunburn?

There are definitely things to keep off your sunburn to avoid further irritation. “Avoid anything that contains oil, petroleum or active ingredients – such as urea, glycolic or salicylic acid,” advises Dr Denning. “Anything that has added scent or alcohol in can worsen the inflammation and further dehydrate the impaired skin barrier – so should be avoided." In other words, stick to plain and simple formulas.

Meanwhile Dr Shotter notes that “you can occasionally find a small amount of alcohol in aftersun products as, on application, it can feel cooling when it evaporates – but it is not good for the skin at all.”

What’s the best way to treat sunburn?

“Sunburn can occur within 10 minutes of sun exposure for some people. When you first notice any signs of sunburn you should get out of the sun, find some shade and have a cool shower or bath to help cool the skin down in the first instance,” says Dr Denning. “Using cooling, gentle aftersun lotions will help to further cool the skin and also replace some of the moisture that will have been lost by being burned.”

In severe cases, Dr Shotter says that ibuprofen can be used to help ease the inflammation in the skin. “Drink extra water while the sunburn heals, as you can become dehydrated,” she adds.
