It is highly photostable and substantive to skin, often combined with other filters for broad-spectrum coverage.
Phoenix Dactylifera (date palm) Extract is derived from date fruit or seeds and is used in cosmetics for its antioxidant, moisturizing, and skin-conditioning properties, owing to its content of polyphenols, flavonoids, sugars, and vitamins. It is generally considered well tolerated in topical formulations.

Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Contact irritation | Uncommon | Mild stinging or redness, especially on sensitive or compromised skin. |
| Allergic contact dermatitis | Rare | Documented in patch-testing as a contact allergen, though sensitization is infrequent. |
| Photoallergic/photocontact dermatitis | Rare | Reaction triggered by combined exposure to the ingredient and sunlight. |
| Potential endocrine activity | Very rare | Weak estrogenic effects observed in laboratory and animal studies; clinical relevance at typical use levels is uncertain. |
| Contact allergic reaction (allergic contact dermatitis) | Rare | Avobenzone is a recognized but uncommon cause of sunscreen allergy. |
| Photoallergic or photocontact dermatitis | Rare | Reactions triggered or worsened by sun exposure have been reported. |
| Skin irritation, redness, or stinging | Uncommon | Mild transient irritation may occur, particularly on sensitive or broken skin. |
| Eye irritation | Uncommon | Can cause stinging if the product migrates into the eyes. |
| Eye stinging | Uncommon | Can occur if sunscreen migrates into the eyes, similar to other UV filters. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
