- Broad Spectrum SPF 50+ — No White Cast — four clear chemical filters covering UVA and UVB, invisible on every skin tone.
- Inje Birch Sap — Hydrates Under SPF — Round Lab's signature ingredient, rich in minerals and amino acids. Most sunscreen leaves skin tight and dry. This one doesn't.
- Twelve Peptides — Anti-Aging in a Sun Stick — copper tripeptide and Argireline lead a full peptide stack working on firmness and expression lines. Rare in any sunscreen, let alone a stick.
- Glyceryl Glucoside — Deeper Hydration — activates your skin's own water channels so moisture goes further than the surface.
- Niacinamide — Evens Tone — brightens and refines pores while you're protected.
- Hyaluronic Acid — hydrates at two molecular depths, keeping skin plump under the SPF layer.
- Aloe, Purslane, Licorice, and Allantoin — a full calming layer, which is what keeps a chemical sunscreen comfortable on reactive skin.
- Made for Reapplying — twist, glide, done. Goes over makeup without disturbing it.

As the last step of a skincare routine, gently apply a sufficient amount on skin, spread it out as if creating a barrier. Before use, gently raise the content slightly(about 5mm). Due to the stick-type formulation, excessive twisting may lead to product breakage or separation.
