Ingredient analysis and how the ad lines read

Read on 2026-09-21

What is this product?

A wax and silicone based sun stick built on three modern UV filters placed at the top of the list, with ceramide NP and phytosphingosine in the later half, but it carries citrus and lavender essential oils plus fragrance allergens that sensitive skin should weigh.

What makes it different?

The filter system relies on three UVA-weighted organic filters, with diethylamino hydroxybenzoyl hexyl benzoate sixth, ethylhexyl triazone ninth and bis-ethylhexyloxyphenol methoxyphenyl triazine tenth, a modern combination often chosen for broad spectrum coverage in a comfortable texture. The stick is anhydrous, so it needs little or no traditional preservative, with 1,2-hexanediol and ethylhexylglycerin handling that role. Barrier oriented touches like ceramide NP, phytosphingosine and hydrogenated lecithin appear late in the list. Essential oils and allergens such as limonene, linalool and citral are present, which limits who can use it comfortably.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.
