I’ve been using this SPF for almost 2 years now and I still love it! The tint adjusts beautifully to my skin tone and gives such a natural, healthy glow without looking heavy or greasy. It applies so smoothly, feels lightweight, and has a very pleasant smell. Most importantly, it doesn’t break me out at all, which is super important for my sensitive skin. I wear it almost every day and it works perfectly under makeup too. The packaging is also super convenient and easy to use, especially for everyday skincare and travel. Definitely one of the best sunscreens I’ve ever tried — worth every penny!
