Octocrylene is an organic (chemical) sunscreen agent that absorbs UVB and short UVA radiation, and is also used to stabilize and solubilize other UV filters such as avobenzone. It is commonly incorporated into sunscreens and daily-care products with SPF.
Homosalate is an organic (chemical) UV filter primarily absorbing UVB radiation, commonly used in sunscreens to help prevent sunburn. It is often combined with other filters as it is relatively unstable and offers limited UVA protection on its own.
Ethylhexyl Salicylate (octisalate) is an oil-soluble organic UVB filter used in sunscreens to absorb ultraviolet radiation in the 295-315 nm range. It is also valued as a solvent that helps stabilize and dissolve other UV filters in formulations.
Butyl Methoxydibenzoylmethane, also known as avobenzone, is a widely used organic sunscreen agent that absorbs UVA radiation. It is often combined with photostabilizers and other UV filters because it can degrade with sun exposure.
Centella Asiatica Flower/Leaf/Stem Extract is a plant-derived ingredient rich in triterpenes (asiaticoside, madecassoside) used in skincare for its soothing, antioxidant, and barrier-supporting properties. It is commonly included to calm irritation and support wound healing and collagen synthesis.
Brassica Oleracea Italica (Broccoli) Extract is a plant-derived ingredient rich in vitamins (A, C, K), sulforaphane, and glucosinolates, used in skincare for its antioxidant and soothing properties. It helps protect skin from oxidative stress and supports overall skin conditioning.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |

| Contact dermatitis / skin irritation | Uncommon | Localized redness, itching, or stinging on application. |
| Photoallergic contact dermatitis | Rare | Reported particularly in adults, sometimes linked to prior ketoprofen sensitization. |
| Systemic absorption | Common | Detectable in blood after use; clinical significance unclear and not equated with harm. |
| Benzophenone formation over time | Uncommon | Degradation can yield trace benzophenone; relevance to skin health under study. |
| Contact irritation or stinging | Uncommon | Mild transient irritation, especially around the eyes or on sensitive skin. |
| Photoallergic/photocontact reaction | Rare | Reaction triggered by sun exposure after application. |
| Potential endocrine activity | Very rare | Weak estrogenic effects observed in laboratory/animal studies; human clinical relevance at typical use levels remains under regulatory review. |
| Mild skin irritation or stinging | Uncommon | Generally well tolerated; transient irritation can occur, particularly on sensitive or compromised skin. |
| Photoallergic or photocontact reactions | Rare | Reported occasionally with organic UV filters; less common than with some other sunscreen agents. |
| Eye irritation on accidental contact | Uncommon | Can cause stinging if the product migrates into the eyes. |
| Contact allergy / sensitization | Very rare | Rarely reported; salicylate derivatives can theoretically trigger sensitization in predisposed individuals. |
| Eye irritation | Rare | May cause irritation on direct ocular contact. |
