Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (also known as Bisoctrizole or Tinosorb M) is an organic-particulate UV filter that provides broad-spectrum protection across both UVA and UVB ranges by absorbing and scattering UV radiation. It is photostable and commonly used in sunscreens, often paired with other filters.
Diethylamino Hydroxybenzoyl Hexyl Benzoate (also known as Uvinul A Plus) is an oil-soluble organic UV filter that absorbs primarily in the long-wave UVA range (around 354 nm), helping protect skin from UVA-induced damage. It is photostable and commonly combined with other filters in broad-spectrum sunscreens.
Ethylhexyl Triazone is an oil-soluble organic UV filter that strongly absorbs UVB radiation (peak around 314 nm), valued for its high photostability and efficiency at low concentrations. It is commonly used in sunscreens and daily-wear products to boost SPF.
Zinc oxide is a mineral (inorganic) UV filter that provides broad-spectrum protection against UVA and UVB radiation by scattering and absorbing light. It also has mild astringent and soothing properties and is used in sunscreens, diaper creams, and barrier preparations.
Titanium dioxide is an inorganic mineral compound used primarily as a physical (mineral) sunscreen agent that reflects and scatters UV radiation, and also serves as a white pigment and opacifier in cosmetic formulations. It is broadly photostable and considered gentle, making it common in products for sensitive and pediatric skin.
Hibiscus Sabdariffa fruit extract is a plant-derived ingredient rich in antioxidants, anthocyanins, and naturally occurring acids (including citric and malic acids) used in skincare for mild exfoliation, antioxidant protection, and skin-conditioning effects. It is sometimes marketed as a 'botanical retinol' alternative due to its purported firming and smoothing properties.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| 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. |
| 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 irritation or contact dermatitis | Rare | Occasional reports of mild irritation, generally considered well-tolerated. |
| Allergic contact dermatitis / sensitization | Very rare | Sensitization is uncommon; large molecular size limits skin penetration. |
| Skin irritation | Uncommon | Generally well tolerated, but mild irritation can occur, particularly with high concentrations or compromised skin barrier. |
| Allergic contact dermatitis | Rare | Documented as a contact allergen in some patch-test studies, occasionally cross-reacting with other alkyl glucosides. |
| Eye irritation | Uncommon | May cause stinging or irritation on direct eye contact, relevant in cleanser and shampoo formulations. |
| Mild skin irritation or stinging | Common | More likely at higher concentrations or on compromised/sensitive skin |
| Irritant contact dermatitis | Uncommon | Non-allergic irritation, often dose-dependent |
| Worsening of pre-existing eczema or barrier-impaired skin | Rare | Penetration-enhancing effect may increase reactivity |
| Systemic toxicity from topical use | Very rare | Reported mainly with extensive application on broken skin, especially in infants or burn patients |
| Skin irritation or mild contact dermatitis | Rare | Occasional reports of localized redness or irritation, generally mild. |
| Photoallergic reaction | Very rare | Uncommon given its photostability, but possible in sensitive individuals. |
