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.
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.
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.
Hyaluronic acid is a glycosaminoglycan that attracts and binds water to the skin, helping to maintain hydration and improve the appearance of plumpness and smoothness. It is widely used in moisturizers and serums and is generally well tolerated across skin types.
Thymus Vulgaris (Thyme) extract is a plant-derived ingredient rich in thymol and other phenolic compounds, used in skincare for its antioxidant, antibacterial, and antiseptic properties. It is sometimes incorporated to support acne-prone or oily skin and as a natural preservative-boosting agent.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Rare | Mild irritation possible in sensitive individuals, though it is generally considered low-risk and well-tolerated. |
| Contact dermatitis/allergic reaction | Very rare | Allergic sensitization to synthetic waxes is uncommon given their inert chemical nature. |
| Pore-clogging/comedogenicity | Uncommon | Occlusive waxes may contribute to follicular blockage in acne-prone skin depending on concentration and formulation. |
| Mild skin irritation | Rare | Occasional transient irritation reported, generally in sensitive individuals. |
| Contact dermatitis / allergic sensitization | Very rare | Very seldom reported; isoeicosane is generally considered low in allergenic potential. |
| Comedogenicity (pore clogging) | Rare | Low comedogenic risk, but possible in acne-prone skin depending on overall formulation. |
| Mild skin dryness | Uncommon | Due to oil-absorbing properties, particularly in high concentrations or on already dry skin. |
| Skin irritation or sensitivity | Rare | Occasional mild irritation reported, more likely with compromised skin barrier. |
| Respiratory irritation from inhalation of loose powder | Rare | Relevant mainly to powdered formulations; crystalline silica inhalation is a concern, but cosmetic-grade amorphous silica poses minimal risk. |
| Allergic contact dermatitis | Very rare | Silica is considered largely non-sensitizing; reactions are exceptional. |
| 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. |
| 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. |
