Frequently asked questions
How do after-sun lotions work?
Whether a product is specifically marketed as an “after sun” lotion or cream, or just has the right formulation to treat sun-stressed skin, “ingredients like menthol or aloe vera can calm inflammation and soothe discomfort, while hydrating ingredients can help prevent peeling and flaking of the skin,” says Connie Yang, MD, a board-certified cosmetic dermatologist in New York City. Hyaluronic acid, shea butter, and coconut oil are all highly moisturizing ingredients that’ll help keep skin looking youthful, supple, and possibly even prolong your tan. (And yes, you can still tan while wearing sunscreen.)
What’s the best way to apply after-sun lotions?
The sooner you use them, the better, according to the dermatologists we spoke with. “Radiation from the sun can continue to damage skin tissue for several hours after exposure. The quicker you can use after-sun lotions, the sooner you can offset the damage and minimize damage,” says Dr. Nazarian. The products that specifically contain aloe can cool skin quickly, so they should be applied immediately.
Can you use an after-sun lotion on a sunburn?
Yes, you can use an after-sun lotion directly on a sunburn. “Ingredients that can quickly decrease the skin temperature can also be useful because UV damage continues for several hours after exposure,” says Dr. Nazarian. “Starting these products quickly can minimize the damage done to tissue.” Those ingredients include aloe, vitamin E, and cocoa butter.
Is there anything you should avoid doing when using an after-sun lotion?
Skin can become very sensitive after exposure to sunlight, and even if you’re back in the shade or have left the beach, damage can still ensue. Dermatologists recommend staying away from anything that will weaken the skin barrier further (think: exfoliating ingredients like glycolic acid, salicylic acid, retinoids). It’s also important to keep skin cool after UV exposure, so try taking a cold shower, and avoid saunas or steam rooms until your skin is fully healed. “Do not pull or peel on any skin that starts to slough or look dry. This is just damaged skin that’s trying to renew itself. Pulling or rubbing the peeling skin will only increase the time it takes to fully heal, and increase risk of infection and scars,” says Dr. Nazarian. Continue applying after-sun lotions until skin is no longer red or peeling.
To find the best after-sun products, we didn’t just rely on expert picks. We tried them ourselves—over and over again. What started as early testing during spring break turned into months of daily use as the weather warmed up and summer officially began. While taking care of skin after outdoor workouts or long afternoons lounging poolside, we’ve put more than 20 lotions, gels, and sprays through real-world conditions. We looked at how the formulas absorbed, how it felt on freshly sun-kissed skin, and whether it delivered on hydration and cooling benefits. We also paid attention to the small but important details, like scent, residue, and how quickly we could get dressed afterward.
