### Which ingredients make this sunscreen a good fit for sensitive skin?

Watermelon Extract and Hyaluronic Acid help make this sunscreen a good fit by calming redness and keeping sensitive skin hydrated. To fit sensitive skin even better, this type of product needs multiple ceramides and soothing agents alongside gentle hydration and protection without harsh additives.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Drug Delivery, 2017](https://pubmed.ncbi.nlm.nih.gov/28155509/)

### What does Watermelon Extract do for sensitive skin?

Watermelon extract helps nourish dry skin by boosting natural lipid production and improving overall moisture content without causing irritation. This type of ingredient works best when paired with gentle barrier-repairing elements to keep sensitive skin soft and calm.
Sources: [Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40871513/)

### What does Hyaluronic Acid do for sensitive skin?

### Where does this sunscreen go in a skincare routine for sensitive skin?

This sunscreen goes in your morning routine as the final step after your cleanser and soothing toner. It helps keep your skin hydrated and protected from the sun without causing irritation, though sensitive skin generally does best with sunscreens containing soothing plant extracts and gentle mineral UV blockers.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [International Journal of Cosmetic Science, 2025](https://pubmed.ncbi.nlm.nih.gov/39138602/)

### Can I use this sunscreen with retinol, and in what order?

You can use this sunscreen in the morning after applying your retinol and other daytime steps, as it is very safe and unlikely to cause irritation. However, because it only offers moderate sun protection and hydration, sensitive skin may need a product with stronger barrier-repairing ingredients like ceramides alongside it.

### How often should I use this sunscreen?

Apply this sunscreen every morning as the final step of your daytime routine. Daily application helps protect against UV rays while keeping skin hydrated, and this product is unlikely to cause irritation on sensitive skin.

### Can this sunscreen clog pores, cause breakouts or purging for sensitive skin?

This sunscreen is unlikely to clog pores or cause breakouts on sensitive skin due to its safe formula, though other sunscreens may fit this skin type better. To work well for sensitive skin, a product of this type needs soothing plant extracts and lightweight hydrators like hyaluronic acid and glycerin.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Is this sunscreen fragrance-free and alcohol-free?
