Vitamin C in summer: yes or no?

June 18, 2026

It happens every summer.

Temperatures rise, we swap out a few products from our routine and one of the most frequently asked questions in the world of skincare makes its return:

Can you use vitamin C during the summer?

The short answer is yes.

Where the myth comes from

For years, the idea that vitamin C and sun exposure don't mix has been widespread. Many people believe that using this ingredient during the warmer months can cause dark spots or increase skin sensitivity.

However, this isn't quite right.

The confusion often arises because certain exfoliating or photosensitising ingredients do require precautions around sun exposure. Vitamin C does not fall into that category.

What does vitamin C actually do?

Vitamin C is one of the most popular ingredients in modern skincare.

It is commonly used in routines focused on improving skin radiance, helping to even out skin tone and giving the complexion a fresher, healthier appearance.

That's why it remains one of the favourite ingredients among dermatologists, formulators and skincare enthusiasts alike.

So, can I keep using it in summer?

Yes.

In fact, many people continue using it throughout the summer.

What matters, as always, is pairing any facial routine with adequate sun protection during the day. Sunscreen remains the true year-round essential, regardless of which active ingredients you use.

The ingredient that never takes a holiday

While some trends come and go, vitamin C continues to hold its place among the most valued ingredients in skincare.

For its versatility, its ease of integration into different routines, and because it helps achieve one of the most sought-after goals year-round: a more radiant, even-looking complexion.

So if you were thinking of putting it away until September, you can rest easy.

Vitamin C knows how to enjoy summer too.
