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.
Nano-sized titanium dioxide is an inorganic UV filter that scatters and absorbs primarily UVB and short UVA radiation, providing broad-spectrum sun protection. The reduced particle size minimizes the white cast associated with conventional titanium dioxide while maintaining photoprotection.
Scutellaria Baicalensis Root Extract is a plant-derived ingredient rich in flavonoids such as baicalin, baicalein, and wogonin, valued in skincare for its antioxidant, anti-inflammatory, and skin-soothing properties. It is commonly used to help calm irritation and protect skin against environmental oxidative stress.
Rubus Idaeus (Raspberry) Fruit Extract is a plant-derived ingredient rich in polyphenols, ellagic acid, vitamin C and anthocyanins, used in skincare for its antioxidant and soothing properties. It is typically included to help defend against oxidative stress and to condition the skin.
Tocopherol (vitamin E) is a lipid-soluble antioxidant used in skincare to protect skin and formulations from oxidative damage caused by free radicals and UV exposure. It also functions as a skin-conditioning and emollient agent and can stabilize oils against rancidity.
Thymus Serpyllum (wild thyme) Extract is a plant-derived ingredient rich in phenolic compounds and essential oil constituents such as thymol and carvacrol, used in skincare for its antioxidant, antimicrobial, and soothing properties. It is often included to support skin conditioning and as a natural preservative-boosting agent.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| White cast / cosmetic residue on skin | Common | Non-micronized particles can leave a visible white film, especially on darker skin tones. |
| Dryness or mild skin tightness | Uncommon | Due to its astringent nature, particularly in high concentrations. |
| Clogged pores / acne aggravation | Uncommon | More often attributed to occlusive base ingredients than to zinc oxide itself. |
| Contact irritation or stinging | Rare | Generally well tolerated; irritation often relates to other formulation components. |
| Allergic contact dermatitis | Very rare | True allergy to zinc oxide is uncommon; reactions usually involve other excipients or fragrances. |
| Skin irritation or mild redness | Uncommon | Generally considered low-irritant; reactions are typically linked to other formulation components rather than the filter itself. |
| Contact dermatitis or allergic reaction | Rare | Titanium dioxide is largely inert; true allergy is infrequently reported. |
| Inhalation risk from spray/powder formulations | Rare | Concern relates to aerosolized nanoparticles reaching the lungs; not relevant to creams or lotions applied to intact skin. |
| Dermal penetration into viable skin | Very rare | Research indicates nanoparticles largely remain on the stratum corneum and do not meaningfully penetrate healthy intact skin. |
| Irritation or sensitivity from impurities | Very rare | Purified/deionized water used in cosmetics is generally inert; reactions are typically due to other ingredients rather than water itself. |
| Transient skin dryness with frequent washing | Uncommon | Repeated water exposure without occlusives may disrupt the skin barrier and increase transepidermal water loss. |
| 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. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
