Can the sun help with acne Or does it make matters worse?

Does sun help acne or make it worse
Sun in moderation is good, but too much can damage and mark acne-prone skin

A little bit of sun is good for your spirits and your skin. But where some people used to recommend sunlamps as a treatment for acne, scientists now know that too much sun is not a good thing for any skin type or condition − and that includes acne-prone skin.

This article looks at how excessive and/or unprotected exposure to the sun’s rays can exacerbate the causes and triggers of acne and make matters worse rather than better. And it explains how you can enjoy the sun and care for your blemish-prone skin at the same time, even if you are undergoing medical acne treatment.

The positive effects of sunlight

Sunlight in moderation is good for our bodies and our minds. It’s an important source of Vitamin D which is essential for many of the vital processes in our body such as the development of healthy bones.

The sun’s rays can lift our mood too. Our body’s ability to produce serotonin (often called the `happy hormone`) is directly affected by sunlight and research has shown that a lack of sunlight can lead to Seasonal Affective Disorder (or S.A.D.) where people get depressed. 

Warm temperatures also stimulate circulation and perspiration, and increased perspiration, when well managed, can help to bring excess oil to the skin’s surface and clear pores.

Some people with acne and/or blemish-prone skin report that their skin condition improves when they enjoy a little bit of sun. Living with acne can be stressful, so if a little bit of sun makes you happy about yourself and your skin then that’s a good thing.

The negative effects of the sun

We’re all individuals, and our skin is as different as we are, so what works for one, doesn’t necessarily work for the next. For every acne patient who says their skin improves in the sun you’ll meet another who says their skin condition is worse during the warmer months. There are a number of possible reasons for this:

You can find out more about how each of these processes contribute to the formation and spread of blemishes in the development of acne.

- Sunlight can also trigger a particular variety of acne known as Acne Aestivalis (or, more commonly, as Mallorcan Acne). This happens when UVA rays combine with the chemicals in certain skincare and sun protection products and trigger an allergic reaction. Acne Aestivalis mostly affects women between 25 and 40, many of whom had a history of acne in puberty and you can read more about it in the different types of acne

- Excessive sun exposure and/or inappropriate sun protection can also cause pigmentation issues and people with acne blemishes or acne scars are particularly prone to hyperpigmentation. You can find out more in Acne and hyperpigmentation.

- And, as we all know, the sun presents other risks for all skin types - not just for those with acne-prone skin. These include sunburn (and ultimately cancer), sun allergies (such as Polymorphic Light Eruption or PLE for short) and premature ageing*1.

What sun protection should I use if I have acne?

Some people with acne-prone skin do their best to avoid sun protection products fearing that the oils and chemicals in the creams will block their pores and make skin worse. Others don’t like the fact that some sun protection products make their skin look shiny.


Effective sun protection is essential for all skin types and skin prone to blemishes and acne are no exception. In fact, choosing the right sun protection can be even more important for acne-prone skin as it is particularly prone to hyperpigmentation. 

The trick is to choose products that have been specially formulated for acne-prone skin and that have been clinically and dermatologically proven to give skin the protection it needs without blocking pores, adding sheen or triggering and exacerbating acne.

Choose light creams, fluids or gels. A lighter texture doesn’t mean you need to compromise on high protection. Look out also for products labelled ‘non-comedogenic’ - this means they don’t contain ingredients that might block pores and trigger blemishes, such as Eucerin Sun Gel-Creme Oil Control, which offers a light texture.  Eucerin Sun Gel-Creme Oil Control is non-comedogenic and is clinically and dermatologically proven to be suitable for blemish-prone skin. It delivers a long-lasting mattifying effect and contains sebum-regulating L-Carnitine to help improve your skin condition.


If you use an acid-based skin peel or resurfacing treatment such as Eucerin’s highly effective DermoPURIFYER Skin Renewal Treatment then it’s important to remember that your skin will be even more sensitive to UVA and UVB rays. We recommend you use the product in the evening and ensure that you apply a high protection factor the following morning.

What sun protection is most compatible with acne treatment?

The active ingredients in several medical acne treatments − e.g. Benzoyl Peroxide, Tretinoin, Adapalene and Azelic Acid − can heighten skin sensitivity to UVA and UVB rays. You can find out more in Acne Medication and side effects. If you are undergoing medical treatment, it’s important that you practice ‘safe sun’. Limit the time you spend outdoors, avoid the sun during its most intense hours, wear protective clothing whenever possible. Choose a high sun protection factor such as Eucerin Sun Gel-Creme Oil Control SPF SPF50+ and be sure to apply it on sunny and cloudy days alike.
