So happy I gave this a try! Regarding its feel, it goes on smoothly and sinks in almost instantly. It provided just the right amount of moisture so my skin stayed fresh and healthy-looking all day long. Perfect fit for my oily skin with enlarged pores after 3 weeks continuously of testing.

Best decision to try this

This sunscreen completely blew me away! On application, the texture was super light and absorbed quickly. It kept my skin deeply hydrated throughout the day without feeling heavy at all, and the finish remained clean and glowy until evening. For reference, I've used this for nearly 3 weeks on my extremely dry, flaky skin during seasonal changes.

Nice texture and feel

Pretty impressive product overall. I've been using it for nearly 3 weeks on my extremely dry, flaky skin during seasonal changes. The application is very smooth and it keeps my skin hydrated and comfortable. The finish is natural, though a light refresh helps by late afternoon. Solid addition!

Best decision to try this

Honestly, this exceeded my expectations. I was wondering how it would feel on my redness-prone sensitive skin, but it exceeded expectations! It spreads evenly, retains moisture for hours, and leaves the skin soft and glowing. Tested for nearly 3 weeks now.

Instant favorite!

I've been incorporating this into my daily routine for 3 weeks continuously now. The formula feels amazingly weightless on skin and layering it was smooth with zero pilling. My oily skin with enlarged pores feels completely nourished and comfortable. Will definitely keep this as a staple!

Holy grail level product

10/10! The texture is fantastic—lightweight yet rich enough to keep dryness away. It didn't cause any irritation on my dull skin that lacks glow and left a non-greasy, natural finish that lasted through my workday. Been using it for nearly a month and loving the results.

As someone with dull skin that lacks glow, finding the right sunscreen is always a challenge, but this one nailed it. After using it for nearly a month, my skin feels noticeably smoother and far more balanced. It applies so effortlessly and gives a healthy, natural radiance that lasts all day. Highly recommended!
