Useful if: choose it if conventional sunscreen creams feel too substantial and you want the lightest, most water like format in this batch.
iUNIK describes this as an ultra low viscosity sunscreen rather than a cream, lotion or gel. The formula is designed to pour and spread more like water while still forming a UV filter layer on the skin.
That format is the main reason to compare it. If texture is what normally makes you dislike sunscreen, this product is meaningfully different from a conventional face SPF.
The brand highlights five UV filters alongside Centella related ingredients and panthenol. It also includes hyaluronic acid, allantoin and resurrection plant extract in the hydration side of the formula.
The 120ml size is also unusually large for a face sunscreen, which may appeal if you prefer one daily product used generously rather than small 40ml or 50ml tubes.
Use it as the final skincare step in the morning after moisturiser, or after lighter leave on products if you do not need a separate moisturiser. Follow the product directions for application amount and reapplication.
The water like texture can make the product feel less substantial, but that should not be used as a reason to apply less than the label directs.
