Round Lab Birch Juice Moisturizing Sun Cream | Review

When my skincare addict friends rave about a product, I pay close attention to it, read more reviews, and if I feel that it suits my skin type, I will go ahead and put it on my wishlist. And since I’ve always been interested in sunscreens more than any product, this sunscreen from Round Lab got me so curious that I have to see what the fuss was all about.


A hydrating SPF 50+, PA++++ broad-spectrum sunscreen that does double duty as a moisturizer. Infused with Birch Juice, Vitamins, and Hylauronic Acid. The vitamin moisture barrier created by this cream helps speed up your skin’s natural healing process.

The Birch Juice Moisturizing Sun Cream (SPF50+ PA++++) has been reformulated last year because of the sunscreen controversy in Korea. The old version was manufacture by Green Cos and the new version has been manufactured by Kolmar Korea, which for me is the most reliable sunscreen manufacturer in Korea. The other sunscreens they manufactured, including this one from Round Lab, have been tested and proven to be over SPF50+ (more about that from this tweet from Odile Monod). It comes in a plastic squeeze tube with 50 ml of white creamy sunscreen. It does not contain any fragrance and scent.

This has diethylamino hydroxybenzoyl hexyl benzoate, ethylhexyl triazone, niacinamide, methylene bis-benzotriazolyl tetramethylbutylphenol, diethylhexyl butamido triazone, glycerin, birch sap (1,425ppm), sodium hyaluronate, hyaluronic acid, dipotassium glycyrrhizate, allantoin, Portulaca oleracea extract, ascorbic acid, adenosine and tocopherol. This sunscreen has only organic/chemical UV filters: diethylamino hydroxybenzoyl hexyl benzoate, ethylhexyl triazone, methylene bis-benzotriazolyl tetramethylbutylphenol and diethylhexyl butamido triazone, which absorb UV radiation and release them as thermal energy. Diethylamino hydroxybenzoyl hexyl benzoate, or Uvinul A Plus, only absorbs UVA. Ethyl hexyl triazone or Uvinul T 150 offers UVB coverage and has the highest photostable absorption among UVB filters. Methylene Bis-Benzotriazolyl Tetramethylbutylphenol or Tinosorb M covers the whole UVA and UVB, is photostable and is used to stabilize less stable UV filters. Diethylhexyl butamido triazone or Uvasorb HEB is very oil-soluble, requires only a small amount to provide SPF, absorbs mainly UVB and UVA2, and reportedly loses 10% of its SPF in 25 hours. Birch sap has organic acids (succinic acid, malic acid, citruline & citruline), amino acids, phenolic acids and betulin, and in studies, has been shown to have anti-aging, antioxidant and moisturizing properties.

For any sunscreen to become a hit for my skin type, my criterias should be met and some of those are that I should be able to to apply 2 fingers worth of it without leaving my greasy or oily residues and it has to be absorbed into my skin in seconds, if not, then immediately on application. And there lies my issue with this product. This is quite thick and creamy and leaves a little greasy feeling behind although that greasiness disappears after about 4-5 minutes. So in order to apply 2 fingers worth of it, I do it in layers — I apply the sunscreen on 1 finger first, wait for at least 4 minutes before applying another layer. It feels moisturizing and looks very dewy on the skin even after it has completely settled. One of the good things I experienced with this is when I’m in a hurry, I just cleanse my face then apply this sunscreen. It’s so moisturizing that it doubles as a moisturizer and sunscreen.

Below is a before and after photo of me applying this after a moisturizer.

Like I mentioned in my introduction, I have friends who rave about this product but I don’t think that this is for me. I think this is more suitable for combination, normal and dry skin types. As of the moment, I won’t be repurchasing this but I will finish it and probably use it during the colder months. If by some chance, my skin changes to a combination skin type in the future, this would be one of the suncreens I will immediately pick up but for now, I’ll be trying other sunscreens from Kolmar to see which one suits me the most.

Have you tried this new sunscreen from Round Lab before? What about the old version? What are your thoughts about it?
