Alcohol is often used in cosmetics for its quick-drying effect and as a solvent, but it can be extremely drying and irritating to the skin. It strips away natural oils, damages the skin barrier, and can cause increased sensitivity, redness, and deep dehydration.

Chlorphenesin is a synthetic preservative with antibacterial and antifungal properties, but it can cause irritation, particularly in sensitive skin. It is often associated with allergic reactions, redness, and discomfort, making it unsuitable for skin with a weakened barrier.

EDTA salts are used to stabilize cosmetic formulas, but they are not biodegradable and contribute to environmental pollution, particularly in aquatic systems.

Although essential oils are natural, they often contain allergens and volatile compounds that can cause skin irritation, allergic reactions, and photosensitivity. Some oils, such as citrus or lavender, can even trigger dermatitis in people with sensitive skin.

Microplastics, such as polyethylene beads, are used in exfoliants and some skincare products, but they pose serious environmental risks. These tiny particles are not biodegradable and contribute to ocean pollution, thus threatening marine life.

Nanoparticles, often found in sunscreens and some cosmetic formulations, are so small they can penetrate the skin and enter the bloodstream, raising concerns about their long-term health effects. While research is still ongoing, Evoé has chosen to exclude them as a precautionary measure.

Parabens are preservatives widely used in cosmetics, but they are suspected of being endocrine disruptors, potentially interfering with hormonal regulation. Some studies suggest they could accumulate in the body over time, leading to potential long-term health risks.

PEGs and PPGs are synthetic compounds used as emulsifiers and thickeners, but they can be contaminated with toxic byproducts such as 1,4-dioxane, a known carcinogen. They can also weaken the skin barrier, leading to increased skin sensitivity.

Phenoxyethanol is a commonly used synthetic preservative, but it can cause skin irritation and raises toxicity concerns at high concentrations. It has been linked to allergic reactions and is not recommended for infants or people with sensitive skin.

Phthalates are used to improve the flexibility of plastics and stabilize fragrances, but they are recognized as endocrine disruptors and have been linked to reproductive health problems.

Silicones provide a soft, silky feel, but they offer no real benefits for the skin and can form a barrier that traps impurities. While not harmful, they can cause residue buildup on the skin and hair. Evoé prioritizes breathable active ingredients that nourish and improve skin health, rather than simply providing fleeting surface effects.

Sulfates are commonly used in shampoos and cleansers for their ability to create a rich lather. However, they are known to be harsh: they strip away natural oils and disrupt the skin's moisture balance. This can lead to dryness, irritation, and even worsen conditions like eczema or psoriasis. Evoé prioritizes gentle, plant-based surfactants that cleanse effectively without compromising hydration or skin health.

Triclosan is an antibacterial agent that has been linked to hormonal disruption and may contribute to antibiotic resistance. It is also harmful to aquatic life when it enters waterways.
