HOW IT WORKS

- Birch Tree Sap nourishes skin by decreasing inflammation, purifies and hydrates with its extensive minerals, enzymes, proteins and antioxidants.

- Amino acids, minerals and Birch Sap vitamins form a moisture-packed barrier to protect skin from drying and prevent loss of hydration.

- A hydrating sunscreen that does double duty as a moisturizer, for all skin types.

Size:1.69 fl. oz (50ml)

ACTIVE INGREDIENTS

Glyceryl Glucoside plays a role in boosting skin's skin's enzymatic antioxidants, which improves skin's environmental defenses. This includes reducing skin's tendency to become dehydrated.

Homosalate absorbs UVB rays, protecting the skin from sunburn, helping to prevent sunburn, skin cancer, and early skin aging.

Niacinamide decreases hyperpigmentation and lightens skin. Also, it helps ease redness from eczema, acne, and other inflammation.

About Birch Trees

Birch Trees are refreshingly tall, snow white, and has been nicknamed “the queen of the forest” due to their romantic images of unspoiled mountain streams and wintry nights. Their white skin, which can be preserved for over a thousand years, sheds into more than ten thinner layers that can be repurposed as “paper” in the old ages. Its roots, sap, and even the mushrooms living off these trees were commonly used for medical purposes.


In the spring, before the leaves have sprouted, Birch tree sap is harvested with a small hole, bleeding its “white sap” that has a slightly sweet flavor and is rich with NMF (Natural Moisturizing Factor, a cocktail of ingredients that the skin naturally creates to keep the stratum corneum hydrated. These include Amino Acids, Lactic Acid, Pyrrolidone Carboxylic Acid (PCA), and Hyaluronic Acid).

Like it!

Clean and light feeling on my skin

Old formula

I only tried the old formula and I love that one. It's not greasy, leaves my skin soft, it's just like a moisturizer. I don't know how the new formula is, would be willing to try a sample.

Expecting Korean Formula

This is a good lightweight sunscreen that blends well. However, I was expecting the Korean formulation and didn’t know it would come with the US one. Therefore, taking off one star.

Sunblock

This sunblock works amazingly! I highly recommend it

03/15/2025

It’s nice

It feels like a lotion on my skin, not greasy. No breakout.

03/10/2025

Love love it I use it daily and have noticed a difference

03/09/2025

It works amazingly well and absorbs to my skin without feeling sticky.

03/08/2025

Amazing!

I’ve been using it for more than 6 months now and I don’t think I’ll go back to another SPF ever. This is perfect for my acne prone skin, non greasy, no white cast, just wonderful! 100% recommended.

Not what I expected

The Birch UVLock was not the Korean version I expected. This contains avobenzone and has the same smell and feel as every other North American sunscreen. It did not make my eyes sting, so that was a 'pro'. But I'm disappointed and will not be buying again.

02/23/2025

I very much reccommend buying if you like your face feeling moisturized and fresh!
