Round Lab Birch Juice Moisturizing Sun Cream SPF50+: everyday moisturizing sunscreen

SPF is the most effective anti-aging and anti-dark spot treatment available, provided you use it every day. The Round Lab Birch Juice Moisturizing Sun Cream SPF50+ PA++++ makes this a pleasant step: it protects, hydrates, and leaves no white cast or greasy residue.

What is Round Lab Birch Juice Sun Cream used for?

It is a very high protection facial sunscreen: SPF50+ against UVB rays (responsible for sunburn) and PA++++, the highest rating under the Asian standard against UVA rays (responsible for skin aging and dark spots). It is used as the final step in your morning routine.

It is enriched with birch sap, harvested in the forests of the Inje region in Korea and known for its hydrating minerals, as well as hyaluronic acid. The result: sun protection that also doubles as skincare, with a radiant, comfortable finish, ideal under makeup.

Key active ingredients

  • SPF50+ PA++++: very high UVB and UVA protection.
  • Birch sap: hydrates and provides minerals.
  • Hyaluronic acid: maintains comfort throughout the day.

Who is it for?

It is suitable for all skin types, and especially:

  • sensitive or reactive skin;
  • dehydrated skin that finds SPFs drying;
  • those who hate the white cast left by sunscreens;
  • everyone, every day of the year.

When should you use it?

Every morning, as the final step in your skincare routine, before makeup—and yes, even on grey days in Brussels: UVA rays pass through clouds and glass. Reapply every 2 hours when exposed to the sun for extended periods.

How should you use it?

  1. After your moisturizer, wait a minute for it to absorb.
  2. Take an amount of cream equivalent to two finger lengths for your face and neck.
  3. Spread evenly, without forgetting your ears, neck, and hairline.
  4. Let it absorb before applying your makeup.

Clow's tip: most people apply twice as little SPF as they should. The "two-finger" rule guarantees the protection stated on the packaging.

What should you pair it with?

To reapply your protection during the day without ruining your makeup, keep the Round Lab Birch Juice Sun Cushion in your bag. In the evening, thoroughly remove your SPF with a cleansing oil such as the Round Lab 1025 Dokdo Cleansing Oil. If you prefer a serum texture, discover the SKIN1004 Hyalu-Cica Sun Serum.

Frequently asked questions
