Seasonal redness: Do the “Centella Asiatica (CICA)” products commonly used by Koreans actually work?
CICA refers to ingredients related to Centella Asiatica, which are very common in Korean skincare products and often appear in soothing and repairing products. On ingredient lists, you’ll see things like Centella Asiatica Extract, Asiaticoside, and Madecassoside.
They’re generally used to help skin look calmer and reduce discomfort caused by dryness, but they’re not medicine and can’t replace treatment.

They may help, but don’t treat “CICA” as one uniform benefit: Centella Asiatica Extract, Asiaticoside (ASIATICOSIDE), and Madecassoside (MADECASSOSIDE) are not the same ingredient, and how they feel in practice depends a lot on the formula. For skin that feels dry and tight or looks red during seasonal changes, a lightweight moisturizer or serum with enough moisturizing power may be more practical than Centella water with a high concentration alone; moisturizing ingredients like ceramides and glycerin are also worth looking for. It isn’t a “fire extinguisher” that works for everyone—fragrance, essential oils, or a complex formula may actually be unsuitable.
I suggest testing a small area behind the ear or along the jaw for a few days, then applying a thin layer to your face; at the same time, temporarily simplify irritating steps like exfoliation and retinol, and don’t try to judge it while layering a bunch of new products. If the redness comes on suddenly, keeps getting worse, or comes with significant pain, swelling, or oozing, don’t tough it out with CICA—see a dermatologist.
Can I still use sunscreen when my skin is red? Would mineral sunscreen be better?
You can, and it’s also a good idea to protect yourself from the sun as much as possible during the day; when your skin is red, what matters more is choosing a formula that feels gentle and that you can tolerate—not focusing only on the word “mineral.” Some people find sunscreens mainly containing zinc oxide (ZINC OXIDE) or titanium dioxide (TITANIUM DIOXIDE) more comfortable, but mineral sunscreens can also be drying, thick, and leave a white cast, and fragrance or other ingredients in the formula may also irritate. Chemical sunscreen doesn’t necessarily mean it’ll be irritating either; there are big differences between individuals and between complete formulas.
If your skin is especially sensitive these days, start by choosing a fragrance-free product with a moderate moisturizing feel and broad-spectrum protection, and test it on a small area along your jawline; if you tolerate it, apply a normal amount to your face. If it feels uncomfortable for now, a hat, sun umbrella, and avoiding strong sunlight can also help. If it causes noticeable stinging or worsening redness as soon as you apply it, stop using it for now and consider consulting a dermatologist.
