Tea Tree Anti-Acne Sunscreen SPF50

A mineral UV filter that sits on the skin surface and reflects and scatters UV light. It is one of the best-studied sunscreen actives and is generally considered non-irritating and safe for use, including on sensitive skin.

A widely used UVB chemical filter with a long safety record at US-approved concentrations. Some lab and animal studies have raised questions about hormone activity and coral reef impact, which is why a few jurisdictions cap or restrict it, but human-relevant risk at labeled use levels is considered low by regulators.

A modern UVA sunscreen filter widely used in Europe and Asia, valued for photostability and low skin penetration. It is not yet approved as a sunscreen active in the United States, which reflects a slower regulatory pathway rather than a specific safety finding against it.

A beta hydroxy acid used to smooth texture and clear pores. Safe at cosmetic levels; can be mildly irritating if overused.

The base most products are built on. It carries the other ingredients and has no safety concern.

A lightweight, volatile silicone that gives serums and primers their silky slip and quick-evaporating finish. Human safety data are reassuring; the EU restriction on this ingredient in rinse-off products is about environmental persistence in waterways, not skin safety.

An ester of palmitic acid and ethylhexanol, commonly used as an emollient and skin-conditioning agent. It is well studied and well tolerated in cosmetics.

A corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

Green tea extract is a well-studied topical antioxidant with a long history of use in serums and moisturizers, generally well tolerated at cosmetic concentrations. Panel safety reviews of Camellia sinensis-derived ingredients have not identified meaningful topical hazard.

Mineral pigments used to add color to cosmetics. Iron oxides are FDA-approved colorants with a well-established safety record in cosmetic formulations.

Pentylene glycol is a humectant and solvent that also offers mild antimicrobial support in formulas. It is generally well tolerated, with only rare reports of irritation, mostly in already sensitive or compromised skin.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

Tea tree oil is used for its antimicrobial reputation in blemish-focused products, but it is a genuine, well-documented contact sensitizer, and its allergy potential rises sharply once the oil has oxidized from air exposure. Fresh, well-preserved, low-concentration formulations are much lower risk than old or improperly stored oil.

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

A preservative that caused a wave of contact allergy in the 2010s. The EU banned it from leave-on products and tightly limits it in rinse-off ones. A genuine concern, not a myth.

A soothing plant extract traditionally used in skincare, valued for its potential anti-inflammatory properties. Published assessments note it is generally well tolerated in cosmetic formulations, though people with sensitivities to botanicals may want to patch test.

Calendula extract is a traditional soothing botanical used in balms and after-sun formulas with a generally reassuring safety history. Like chamomile, it is part of the Asteraceae family, so cross-reactive contact allergy is possible for people already sensitive to ragweed or related plants.

Chamomile extract is used for its soothing and mild antioxidant reputation and is generally well tolerated. It belongs to the Asteraceae (Compositae) plant family, so people with a known ragweed or daisy-family allergy occasionally react to it and may want to patch test first.
