Please tell me the difference between sunscreen and sun gel.

I used to mainly use liquid sunscreen. I used it well because it didn't cause any skin trouble. However, after the product I loved was discontinued, I started using one with a different sun gel ingredient, and now my skin tans quickly or I have to reapply it.

My skin troubles have worsened due to the hassle. It used to provide good protection after I used the sunscreen, but it was discontinued the year before last. Now

I am looking for a sunscreen that suits me. The two products

If you could explain the differences clearly, I will take them into consideration when making a purchase.
