    Nothing. None of the experts who reviewed it raised a problem.

    What the gurus are saying

    This sun stick is exceptional as an SPF lip balm: experts praise it for no white cast and a hydrating finish that adds subtle glow without greasiness. The formula proves especially beneficial for dry skin, delivering niacinamide, hyaluronic acid, and peptides to smooth and hydrate. Sunscreen sticks tend to skip areas, so use it for targeted application around eyes and lips rather than full body coverage.

    "This is the Round Lab Birch Juice Moisturizing Sunstick. They changed the packaging since I tried this before, when it was in a little round stick. Personally I like this shape better, it's just a bit faster, and that's a great sunstick, so I'm happy to have that back in my collection."

    "If you have dry skin, the Round Lab Birch Juice Moisturizing Sun Stick is definitely a great option because it still leaves that invisible finish, there's no white cast, it glides onto the skin very smoothly, but unlike the other, this one leaves a nice hydrated sheen to it to add a little bit of that glow. It doesn't leave the skin greasy, but instead of mattifying, it adds a nice glow. This one is super popular on TikTok as well, SPF 50 protection, and it glides so nicely onto the skin. If you're someone who wants a little bit of that moisturizing feel, that nice light glow, this is a great option."

    "I really like this product a lot actually, this is great. First of all I love how cute the packaging is. This is a chemical sunscreen. I like using this as an SPF lip balm, it works really well. With sunscreen sticks you need to be careful because they're prone to skip areas, so I don't rely on a sunscreen stick as my body sunscreen if I was going to be out at the beach, but they are really handy for applying around your eyes or your lips. It's got niacinamide and a variety of peptides, it's a really moisturizing formula, free of fragrance. Chemical sunscreen, no cast."

    "The first is the Round Lab Birch Juice Moisturizing Sun Stick. Wow, is this ever good for the lips. It's a broadspectrum sunscreen that does not leave any white cast. It has Avobenzone, Octinoxate, and Titanium Dioxide. It has niacinamide which is going to be beneficial for the lips just like the rest of your face. It also has peptides and hyaluronic acid. Peptides do help with improving water content along with hyaluronic acid, which is really helpful for keeping your lips hydrated, smooth, cutting down on lip irritation, and having a plumping effect without being irritating. Specifically, it has the infamous peptides that constitute Matrixyl 3000. It also has copper peptides. Now, allegedly these peptides are going to help with collagen production, but more research is needed to support that. At the end of the day, they do help with moisturizing the skin."

    "I've also been using the stick version of this as an SPF lip balm and rather enjoying that too."

    What the evidence says.

    Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

    Vitamin C

    Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

    Niacinamide

    Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

    Humectants and emollients

    Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
