How it works
This 30ml serum handles the serum step: it delivers a targeted dose of its lead ingredients to the areas that need it most. Butylene Glycol is the third ingredient on this product's own manufacturer list of 45, a solvent and humectant used to help carry the other ingredients, which is why the formula reads as more than a generic serum rather than a name-only claim. Used AM and PM, after essence and before moisturizer, it sits in that position of a Korean-style routine, not as a stand-alone product.
Key benefits
- What it is: a 30ml serum from K-Secret, for the serum step.
- On the ingredient list: Butylene Glycol, Glycerin, Niacinamide, confirmed on this product's own manufacturer list rather than assumed from the category.
- Fits into the routine: delivers a targeted dose of its lead ingredients to the areas that need it most.
- Original Korean Formula: the version sold on Korean shelves, not a US reformulation.
