Moisturizer and sunscreen are the two steps most K-beauty routines refuse to skip, and Round Lab has packaged both from its Birch line into one duo. This guide covers what is inside according to Round Lab, how to use the two products in order, and what to check before you buy.
What Round Lab says about it
Round Lab calls this set the Birch Hydration & UV Protection Duo. It pairs two full products from the Birch line, which the brand builds around birch sap for moisture:
- Birch Moisturizing Cream: according to Round Lab, a lightweight yet intensely hydrating cream that replenishes moisture, soothes irritation and fortifies the skin barrier with birch sap and amino acids. The brand says it leaves skin feeling soft, supple and refreshed.
- Birch Moisturizing UVLock Sunscreen: described by Round Lab as an award-winning, deeply hydrating sunscreen with SPF 45+ broad-spectrum protection. It is formulated with birch sap and niacinamide, and the brand says it calms sensitivity, absorbs effortlessly and leaves no white cast.
Round Lab says the pair works together to moisturize, strengthen the skin barrier and provide broad-spectrum sun protection, and presents the duo as suitable for daily use, "rain or shine."
Where it fits in a routine
A common K-beauty order is cleanse → toner → serum → cream → sunscreen. These two products cover the last two steps.
Morning:
- Cleanse, then apply your toner and any serum you already use.
- Birch Moisturizing Cream.
- Birch UVLock Sunscreen as the final skincare step, before any makeup.
Night:
- Cleanse well to remove sunscreen (a double cleanse is popular in K-beauty if you wore makeup).
- Toner and serum.
- Birch Moisturizing Cream. Skip the sunscreen at night.
Follow the directions on each product's label for how much sunscreen to use and when to reapply; the duo's product page does not list amounts.
Who it might suit
Going by Round Lab's descriptions, this duo is aimed at people who want hydration and daily sun protection from one line. It could be a good fit if you:
- want a simple two-step finish to your routine without matching products from different brands;
- prefer a sunscreen that Round Lab describes as hydrating with no white cast;
- like the Birch line's moisture focus, or are curious about the K-beauty sunscreens often talked about by K-pop fans.
The product page for this duo does not list skin types, sizes or full ingredients, so check each product's own page if those matter to you.
What to check before you buy
- Price: the duo is listed at $45.74 on Round Lab's US store at the time of writing. Check the current price on the brand page, since deals change.
- Shipping: if you are outside the US, check whether Round Lab ships to your country and what fees apply. Sunscreen labeling and SPF rules differ between countries.
- Patch test: try each product on a small area first, especially the sunscreen if your skin is sensitive, and stop if you notice irritation.
- Sizes and ingredients: these are not on the duo listing, so look them up on the single-product pages.
Our take
We have not tested either product, so this is based only on Round Lab's description. The appeal of the duo is simplicity: one moisturizer and one SPF 45+ sunscreen from the same birch sap line, covering the last two steps of a morning routine. If you already have a cleanser and toner you like, this set can slot in on top. As with any new sunscreen, patch-test first and confirm the details on the brand page before ordering.
