Using Brightening Serums in Summer: Do They Cause or Prevent Dark Spots?
If there’s one recurring question every time summer approaches, it’s this one:
Can I use a brightening serum if I’ll be out in the sun, or is it not recommended?
Some say yes, others say no… but what does it really depend on? How can you know what to do with your dark spot serum in summer?
Well, friend, depending on what your brightening serum is made of, you can—or shouldn’t—use it during periods of high sun exposure. But first things first: if you’re worried about your dark spots, don’t miss this blog post!
Which Brightening Ingredients Should You Avoid in Summer?
Those that contain photosensitizing actives, such as strong exfoliating acids or retinoids—especially if your skin is not used to them, as we explained in this blog.
But… what’s the point of having a dark spot serum that you can’t use to prevent them exactly when they’re most likely to appear? To us, that makes no sense. That’s why, in Brightening Serum, we combined the most powerful active ingredients on the market that are safe for sun exposure. You won’t find any photosensitizing ingredients or super strong exfoliating acids in the formula—only a perfect blend of safe and effective actives to treat and prevent dark spots, even in summer ;)

Ideal Ingredients to Treat and Prevent Dark Spots—That Are Safe in Summer:
- Niacinamide. Antioxidant, sebum-regulating, anti-inflammatory, and yes—brightening.
- Azelaic Acid. Non-photosensitizing and suitable for both day and night use. An excellent brightening agent with anti-inflammatory properties, ideal for blemishes and redness.
- Vitamin C (in stable and well-formulated concentrations). The ideal antioxidant for dull skin. It brightens, fades dark spots, and evens out the skin tone.
- Arbutin. Safe for summer use and highly recommended. It inhibits melanin production, preventing new dark spots from forming.
- Tranexamic Acid. A stable, sun-safe active; very effective for melasma and post-inflammatory hyperpigmentation.
- Licorice Extract. A gentle anti-inflammatory and brightening ingredient that helps calm and prevent hyperpigmentation.
As you can see, there are tons of options out there to help prevent and avoid dark spots this summer. Because yes—it’s much better to prevent their appearance from the moment sun exposure starts, rather than wait until September to treat them once they’ve already formed. No doubt about it: preventive skincare is the most effective kind.
So if you don’t want dark spots this summer, grab Brightening Serum—it’s the complete package! Its formula contains: 5% azelaic acid 3% tranexamic acid 2% arbutin and licorice extract. Honestly, it’s got everything you need to forget about dark spots this summer!
I hope this cleared up your doubts about what you can keep using for your dark spots during summer. If anything’s still unclear, don’t hesitate to write to us—we’ll be happy to help you out.
