Rosa rubiginosa (rosehip) seed oil is a plant-derived oil rich in essential fatty acids (linoleic and alpha-linolenic acid) and minor amounts of carotenoids and tocopherols, used to soften skin, support the barrier, and provide antioxidant activity. It is sometimes studied for improving the appearance of scars, hyperpigmentation, and photoaged skin.
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (also known as Bemotrizinol or Tinosorb S) is a broad-spectrum organic UV filter that absorbs both UVA and UVB radiation. It is highly photostable and is commonly used in sunscreens and daytime skincare products to provide photoprotection.
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.
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 stinging | Uncommon | Mild transient irritation possible, more likely with oxidized oil. |
| Allergic contact dermatitis | Rare | Sensitization to plant components has been occasionally reported. |
| Comedogenicity / acne aggravation | Rare | Generally low comedogenic potential, but occlusive use may worsen acne-prone skin in some individuals. |
| Reactions from rancid/oxidized oil | Rare | Degraded oil with peroxides can increase irritation risk; proper storage reduces this. |
| Mild irritation or stinging | Rare | Generally well tolerated; transient irritation possible in sensitive individuals. |
| Comedogenicity / acne flare | Very rare | Considered low on the comedogenic scale, but rare breakouts reported in acne-prone users. |
| Contact irritation (redness, stinging) | Uncommon | Typically mild and transient, more likely in sensitive skin or high concentrations. |
| Iodine-related concern | Very rare | Marine extracts may contain trace iodine; theoretical relevance for iodine-sensitive individuals. |
| Mild skin irritation | Rare | Occasional transient irritation reported in sensitive individuals. |
| Comedogenicity (pore clogging) | Rare | Low comedogenic potential but possible in acne-prone skin. |
| Mild transient stinging or irritation | Rare | Occasional in sensitive or compromised skin; usually mild and short-lived. |
| Redness or itching | Rare | Generally associated with overall formulation rather than the ingredient alone. |

| Ingredient | What it does |
|---|---|
| Aqua Solvent / vehicle | Aqua (water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble components and forms the medium for emulsions. It has no direct treatment activity and primarily contributes to texture, spreadability, and product delivery. |
| Rosa Rubiginosa Seed Oil Key active Emollient / antioxidant oil | Rosa rubiginosa (rosehip) seed oil is a plant-derived oil rich in essential fatty acids (linoleic and alpha-linolenic acid) and minor amounts of carotenoids and tocopherols, used to soften skin, support the barrier, and provide antioxidant activity. It is sometimes studied for improving the appearance of scars, hyperpigmentation, and photoaged skin. |
| Olive Squalane Emollient / occlusive moisturizer | Olive squalane is a hydrogenated, stable form of squalene derived from olives, used as a lightweight emollient that mimics skin's natural lipids to reduce moisture loss and improve skin softness. It is widely tolerated across skin types and serves as a base or carrier ingredient rather than a therapeutic active. |
| Red Algae Extract Humectant / antioxidant | Red algae extract is a marine-derived ingredient rich in polysaccharides, vitamins, and minerals used in skincare for its hydrating, antioxidant, and skin-conditioning properties. It can help retain moisture and may support skin barrier function. |
| Isoamyl Laurate Emollient | Isoamyl Laurate is a plant-derived ester (from isoamyl alcohol and lauric acid) used as a lightweight, fast-spreading emollient that improves skin feel and product texture. It functions to soften and condition the skin and acts as a natural alternative to silicones. |
| Sodium PCA Humectant | Sodium PCA (sodium pyrrolidone carboxylic acid) is the sodium salt of pyroglutamic acid and a component of the skin's natural moisturizing factor (NMF). It is widely used in cosmetics as a water-binding humectant to hydrate and soften the skin. |
| Olive Oil PEG-7 Esters Emollient/emulsifier | Olive Oil PEG-7 Esters is a water-dispersible derivative of olive oil produced by reaction with polyethylene glycol, used in skincare as an emollient, emulsifier, and mild solubilizer. It conditions skin and helps blend oil and water phases in formulations. |
| Kaolin Absorbent/clay cleanser | Kaolin is a naturally occurring soft white clay (hydrated aluminum silicate) used in skincare to absorb excess sebum, oil, and impurities. It is commonly found in face masks, cleansers, and powders as a mattifying and gentle exfoliating agent. |
| Xanthan Gum Thickener/stabilizer | Xanthan gum is a polysaccharide produced by bacterial fermentation, used in skincare as a thickening, gelling, and emulsion-stabilizing agent. It improves product texture and suspension of ingredients without contributing active treatment effects. |
| Propylene Glycol Humectant / solvent | Propylene glycol is a small glycol molecule widely used in skincare as a humectant, solvent, and penetration enhancer that helps attract water and dissolve other ingredients. It is considered a base/formulation ingredient rather than a therapeutic active. |
| Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine Key active UV filter (sunscreen) | Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (also known as Bemotrizinol or Tinosorb S) is a broad-spectrum organic UV filter that absorbs both UVA and UVB radiation. It is highly photostable and is commonly used in sunscreens and daytime skincare products to provide photoprotection. |
| Behenyl Alcohol Emollient / Thickener | Behenyl alcohol is a fatty alcohol derived from behenic acid that functions as an emollient, thickening agent, and emulsion stabilizer in cosmetic and skincare formulations. It helps soften the skin and improve product texture and stability. |
| Capryloyl Glycerin Emollient/skin-conditioning agent | Capryloyl Glycerin is a glyceryl ester of caprylic (octanoic) acid used in cosmetic formulations primarily as an emollient, skin-conditioning agent, and texture enhancer. It helps soften skin and improve the sensory feel of creams and lotions rather than acting as a therapeutic active. |
| Methylene Bis-Benzotriazolyl Tetramethylbutylphenol Key active UV filter (broad-spectrum) | 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. |
| Beta Vulgaris Root Extract Antioxidant / skin-conditioning | Beta Vulgaris (beet) root extract is a plant-derived ingredient rich in betalains, sugars, and antioxidants, used in skincare for its conditioning, humectant, and free-radical-scavenging properties. It is generally regarded as mild and well-tolerated in topical formulations. |
| Heptyl Undecylenate Emollient / skin-conditioning agent | Heptyl undecylenate is a lightweight ester derived from undecylenic acid and heptyl alcohol, used in cosmetic formulations as an emollient and dry-feel skin-conditioning agent. It imparts a smooth, non-greasy texture and can serve as a natural-derived alternative to silicones. |
| Glycerin Humectant | Glycerin is a widely used humectant that attracts and retains water in the skin, helping to hydrate the stratum corneum and support barrier function. It is considered safe and well-tolerated across most skin types and concentrations. |
| Hydrolyzed Corn Starch Humectant / skin-conditioning agent | Hydrolyzed Corn Starch is a partially broken-down corn starch derivative used in cosmetic formulations as a humectant, film-former, and texture modifier.
