## Key benefits

- Birch Juice Mild-Up UV Lock Sunscreen is Round Lab's sunscreen, sourced for the Korean market rather than reformulated for US shelves.
- Carries Zinc Oxide, which is a mineral UV filter, the reflective, physical-sunscreen ingredient in this formula.
- Carries Sodium Hyaluronate, which is a salt-form humectant from the hyaluronan family, smaller and faster-absorbing than the parent molecule, and a staple of Korean hydration formulas.
- Carries Hyaluronic Acid, which is the water-binding polymer most Korean hydration formulas are built around.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.
- Suited to shoppers targeting dehydration and a compromised moisture barrier.

## How it works

Round Lab Birch Juice Mild-Up UV Lock Sunscreen is built as a sunscreen, so its texture and finish are designed around one specific place in a routine rather than several. Round Lab, TIRTIR and Torriden formulate this kind of sunscreen to feel consistent with the rest of the brand's line, so the texture and absorption speed match what the format is meant to do. The texture is built for use last, as the final step of your morning routine, before makeup, which is why it behaves differently on skin than a product meant for a different point in a routine. This is the Korean-market formula of the birch juice mild-up uv lock sunscreen, the version sold on shelves in Korea rather than a formula reworked for a different market.

## How to use

1. Use the Birch Juice Mild-Up UV Lock Sunscreen as the last step of the morning routine, over moisturizer and under makeup.
2. Apply it at the last stage of skincare routine 15 minutes before heading out. Gently massage for better absorption.
3. Nothing skincare goes over it. It is the last thing on in the morning, and it is never mixed into the moisturizer underneath it.
4. Every morning, and again through the day as the instruction on the pack directs. Do not stir it into your moisturizer to save a step.

## FAQ

### Is this the same formula sold in Korea, or a version made for the US market?

This is the Korean-market formula, the same one sold on shelves in Korea, not a separate version reformulated for US retail. The pack you open matches what a shopper in Seoul buys.

### Where does this step go in a routine?

It belongs last, as the final step of your morning routine, before makeup. Placing it earlier or later than that changes how it feels going on and how well the steps after it absorb, so keeping it in that order is worth doing even on a simplified routine.

### Can I use this if my skin runs sensitive?

This sunscreen is formulated with skin types like normal skin, dry skin in mind, but any new product is worth a patch test first if your skin reacts easily. A short patch test on the inside of your arm or behind an ear is worth doing with any new product before it goes on your face, and that goes for sensitive skin most of all.

### How long before I will know if this is right for my skin?

Give it a full week or two of consistent use before judging, since a single use rarely tells you much either way. Watch for how skin feels rather than for any specific number, and stop use if you notice ongoing irritation.
