Having used the Skin Aqua Hyaluronic Acid Serum UV SPF 50+ myself, I can attest to its wonderfully light, watery texture that feels more like a serum than a typical sunscreen. This makes it incredibly comfortable to wear, especially on hot days when heavier formulas tend to feel greasy or clog pores. I found that the 'watery break' when spreading the product means you have to be patient and rub it in thoroughly to avoid streaks. This step is crucial to achieving the slight dewy finish without any uneven patches. One aspect I appreciated was how well the product held up after multiple reapplications throughout the day. Its lightweight nature encourages reapplication, which is key for effective sun protection. However, I did notice that it is not very rub-resistant. For example, if I accidentally leaned my face against my hand or fabric, some transfer occurred. So if you're outdoors or active, frequent reapplication might be necessary. Another personal tip is to use this sunscreen under makeup or alone, as it doesn't feel heavy or sticky, enhancing overall comfort during the day. The added benefit of hyaluronic acid means it also helps keep skin hydrated, making it suitable for those with normal to dry skin types. In summary, this sunscreen is an excellent choice if you prioritize a lightweight feel and hydrating properties in your SPF. Just remember the need to blend it well and reapply occasionally due to moderate rub resistance.
