Sunscreen is the one step almost every K-beauty routine agrees on, and plenty of K-pop fans pick up the habit after seeing how seriously idols take sun protection on tour. Round Lab has teamed up with swimwear brand Kulani Kinis on a limited-edition set built around sun care. Here is what the product page tells us, and what to think about before you buy.
What Round Lab says about it
According to Round Lab, the [Limited Edition] Kulani Kinis X Round Lab Sun and After Sun Glow Bundle is a collaboration between the two brands, made to help you "chase the sun" and protect your glow. The brand says the set comes tucked inside an exclusive pink "Sun Chasers" pouch and is a 9-piece set that combines Round Lab's best-selling Birch sun care with after-sun products.
The bundle is listed at $110.00 on Round Lab's US store at the time of writing. As a limited edition, it may not stay in stock for long, so check the brand page for the exact list of the nine pieces, their sizes and availability.
For context, Round Lab describes its Birch line as its moisture-focused range, so this set pairs sun protection with that hydrating concept.
Where it fits in a routine
In a Korean routine, sunscreen is the last step of the morning: cleanse, toner, serum, cream, then sunscreen. After-sun care comes later in the day, once you are back indoors after time outside.
- Morning: finish your usual routine with the sunscreen from the set, following Round Lab's directions for amount and reapplication.
- Outdoors: the pouch makes it easy to carry what you need for a beach day, a festival or a concert queue in the sun.
- Evening: after cleansing, use the after-sun items as directed on their labels.
Who it might suit
- People planning a trip, beach holiday or lots of outdoor events and who want sun and after-sun care in one pouch.
- Fans of Round Lab's Birch sun care who want a bigger set.
- Anyone who likes limited-edition collabs or wants a ready-made gift for a friend who travels.
If you only need one sunscreen for daily use, a single Birch product from Round Lab may be a better fit than a 9-piece set.
What to check before you buy
- What is inside: confirm the nine items and their sizes on the brand page.
- SPF and labels: check the SPF and protection details printed on each sun product, and follow the reapplication guidance.
- Ingredients and patch test: read the ingredient lists and test new products on a small patch of skin first.
- Sunburn: after-sun products are not a treatment. For a painful or blistering burn, see a medical professional.
- Travel rules: if you fly, check your airline's liquid limits for carry-on bags.
- Shipping and price: the price above is from Round Lab's US store. Check shipping to your country and the current price on the brand page.

Our take
This collab is a fun option if you want a complete sun-day kit in one pouch and you already like the idea of Round Lab's Birch sun care. We have not tested it, so the claims above are Round Lab's own. Since it is a limited edition, check the contents, stock and shipping before you decide, and patch test anything new before a big day out.
