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.
Phenylbenzimidazole Sulfonic Acid (Ensulizole) is a water-soluble organic UV filter that primarily absorbs UVB radiation, helping to prevent sunburn. Its water solubility makes it suitable for lighter, less greasy sunscreen and daily moisturizer 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.
Disodium Phenyl Dibenzimidazole Tetrasulfonate (also known as bisdisulizole disodium or Neo Heliopan AP) is a water-soluble organic UV filter that absorbs primarily in the UVA range, used in sunscreens and daytime skincare to enhance photoprotection. Because it is hydrophilic, it remains in the aqueous phase of formulations and is generally non-penetrating.
Aesculus Hippocastanum (Horsechestnut) Extract is a plant-derived ingredient rich in aescin (escin) and flavonoids, used in skincare for its anti-inflammatory, antioxidant, and capillary-strengthening properties. It is commonly included in formulations targeting redness, puffiness, and the appearance of fragile or dilated blood vessels.
Symphytum Officinale (Comfrey) Extract is a botanical derived from the comfrey plant, valued in topical formulations for its allantoin content, which provides soothing, hydrating, and skin-conditioning benefits. It is commonly used in moisturizers and after-sun or sensitive-skin products to support skin comfort and barrier function.
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 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. |
| Contact irritation | Uncommon | Mild stinging or redness, especially on sensitive or compromised skin. |
| Allergic contact dermatitis | Rare | Sensitization reactions reported in patch-test studies. |
| Photoallergic/photocontact reactions | Rare | Reaction triggered upon UV exposure; documented occasionally. |
| Eye irritation | Uncommon | Can sting if product migrates into the eyes. |
| 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. |
| Skin or scalp irritation | Uncommon | Mild irritation possible, particularly in leave-on or high-concentration products; amphoteric surfactants are generally lower-irritation than anionic types. |
| Skin irritation | Uncommon | Mild stinging or irritation, more likely at higher concentrations or on compromised skin. |
| Contact urticaria | Very rare | Hives or wheal reaction reported in isolated cases of hypersensitivity. |
