Micro Active Sun Serum (su:m37)
Korean consumers rated it like this!!
Living in Korea, I've experienced all sorts of weather, from scorching hot summers to dry, chilly winters. The su:m37 Micro Active Sun Serum has been my constant companion through it all.
During the humid summer months, its lightweight, serum-like texture is an absolute lifesaver. It doesn't feel sticky or heavy on my skin, which is crucial when the temperature soars. It absorbs quickly, leaving a smooth, non-greasy finish that's perfect under makeup.
In the drier winter months, I was initially worried it might not be hydrating enough. However, I was pleasantly surprised! The serum provides a comfortable layer of moisture without feeling occlusive. My skin feels protected from the sun's rays, which can still be strong even in winter, and it doesn't feel tight or dehydrated.
I've used it during intense outdoor activities, like hiking, and it held up remarkably well. Reapplication is easy because it blends in so seamlessly. It hasn't caused any breakouts, even with frequent use and layering with other K-beauty products.
The fact that it doesn't leave a white cast is a huge plus, especially for my skin tone. It just melts into the skin, leaving a natural, healthy-looking finish. It truly feels like a skincare step rather than just a protective barrier.
Overall, its performance in the diverse Korean climate has been outstanding. It's gentle enough for daily use, effective enough for prolonged sun exposure, and feels luxurious on the skin. It's become an indispensable part of my Korean skincare routine.
Products that go well together
To maximize the benefits of the su:m37 Micro Active Sun Serum, consider pairing it with these complementary products:
Hydrating Toners: Follow up with a hydrating toner like the su:m37 Water-full Rebalancing Toner or a similar essence to boost moisture levels.
Gentle Cleansers: At the end of the day, use a gentle cleansing oil or balm, such as the su:m37 Skin Saver Essential Cleansing Oil, to effectively remove the sunscreen and impurities without stripping the skin.
Nourishing Serums/Essences: Layering with other hydrating or brightening serums can enhance your skin's overall health. Look for products with hyaluronic acid, niacinamide, or vitamin C.
Lightweight Moisturizers: If you need a bit more moisture, opt for a light gel-cream or lotion that won't feel heavy over the sun serum.
