Some people believe that the heat of the sun will improve acne-prone skin by drying out the oil and reducing pimples. But contrary to popular thinking, the sun is far from a friend for oily skin

During sun exposure, UV rays do help to dry up blemishes. However, soon after exposure, they induce excess sebum production, causing the skin barrier to thicken and clogging the pores, leading to spots and blackheads. The sebum produced remains under the skin and bacteria multiplies. A few days later, an acne outbreak is very likely to occur. An acne outbreak after sun exposure is called the rebound effect.

As the rebound effect is not instantly visible on acne-prone skin, it is often misunderstood or underestimated. Every summer, dermatologists warn their patients of the risks of sun exposure for oily skin. To avoid outbreaks, make sure you are protected from the sun with an adapted sunscreen for oily or acne-prone skin

Additionally, the sun can intensify acne scars and darken spots, as UV rays are responsible for hyperpigmentation.

If you are using medication or topical treatments against acne, your skin is sensitised and will burn faster and may react more strongly to the sunlight. In this case, it is extremely important to protect your face every day, as the UV rays will stress your sensitised skin and can provoke pimples. Don’t forget that you are exposed to UV rays all year round, not only when the weather is sunny.

Good to know: What is sebum?

Sebum is an oily substance produced by your body’s sebaceous glands. Made of a mix of lipids, fatty acids, waxes and other natural chemicals, it sits on the surface of the skin and is responsible for protecting and moisturising it. Sebum-producing sebaceous glands are located all over the body, although the face and scalp contain the highest concentration. Oily skin occurs when the body produces an excessive amount of lipids that make up sebum. 

Effective photoprotection is the best solution to avoid the rebound effect. Using sunscreen daily avoids the negative effects of the sun on combination and oily skin, notably the overproduction of sebum that can clog the pores. As the sun can aggravate hyperpigmentation, using sunscreen also helps avoid acne scars.

When choosing a sunscreen for your face, check whether it is suitable for combination, oily or acne-prone skin. Products tailored for these skin types mostly contain active ingredients that can help improve and protect your skin, while avoiding making spots and pimples worse.  More than protecting your face from the sun, it provides skincare benefits. 

Certain ingredients can help inhibit acne, such as glycolic acid and salicylic acid. They have long been used in dermatology and are renowned for their keratolytic action. This means that they gently exfoliate the skin, remove dead cells, and smooth irregularities. This prevents the skin from thickening and the subsequent rebound effect.

Combining several fine powdery ingredients can help control shine and mattify your skin. A sunscreen product with a mattifying action absorbs excess sebum on your face.

A non-comedogenic or non-acnegenic product will not clog or block your pores. When buying a suncare product, it is very important to check that it is non-comedogenic, otherwise it may obstruct your pores and aggravate acne.

The best sunscreen is the one that is used frequently. The texture needs to be pleasant and suit your needs to ensure that you want to apply it daily. Opt for a sunscreen that is easy to apply, non-greasy and with a soft feel. If you use make-up, also make sure the sunscreen is a good base.   and won’t flake while applying your foundation.
