Phenoxyethanol is a preservative that prevents bacteria, yeast, and mold from growing in skincare products, helping them stay fresh and safe to use. It has been used safely in cosmetics for decades and is effective at very low concentrations.
Benefits
Prevents microbial contamination and product spoilage
Broad-spectrum antimicrobial activity against bacteria and yeast
Minimal impact on beneficial skin bacteria when used at approved levels
Potential concerns
Rare allergic contact dermatitis in sensitive individuals
May cause irritation if used in products at concentrations above 1%
Science: The European Scientific Committee on Consumer Safety considers phenoxyethanol safe for all consumers, including children, at concentrations up to 1%. Adverse effects observed in animal studies required exposure levels approximately 200 times higher than those in cosmetic products, and it is classified as one of the most well-tolerated preservatives in cosmetics.
Ethylhexylglycerin is a preservative and antimicrobial ingredient used to prevent bacterial growth and extend shelf life in skincare products. It's a multifunctional ingredient that helps keep formulations stable and free from contamination.
Benefits
Prevents bacterial contamination in products
Helps extend product shelf life
Works synergistically with other preservatives for enhanced protection
Potential concerns
May not be effective against all bacterial species (notably some Pseudomonas aeruginosa strains)
Preservative-related sensitization possible in sensitive individuals, though uncommon
Science: Research shows ethylhexylglycerin has broad antimicrobial activity against many common cosmetic contaminants, though effectiveness varies by bacterial species. Studies demonstrate it can work synergistically with other preservative components to enhance biofilm inhibition.
Lemon fruit extract is a natural ingredient derived from lemon juice and pulp, rich in vitamin C, citric acid, and antioxidants. It's used in skincare for its brightening and mild exfoliating properties, and to help balance skin pH.
Benefits
Brightening and radiance boost
Antioxidant protection from vitamin C
Gentle chemical exfoliation via citric acid
May help even skin tone
Potential concerns
High citric acid content can irritate sensitive or compromised skin
Photosensitivity risk—products with high lemon extract should not be used before sun exposure without SPF
May cause stinging or dryness in sensitive individuals
Science: Limited peer-reviewed data available for this ingredient. General knowledge of citrus extracts suggests benefits from vitamin C and citric acid, but stability and efficacy vary widely depending on formulation and concentration.
Paraffin (also called mineral oil or liquid paraffin) is a lightweight, odorless oil derived from petroleum that sits on the skin's surface. It works as an occlusive ingredient, creating a barrier that traps moisture and prevents water loss from the skin.
Benefits
Locks in skin hydration by reducing evaporative water loss
Helps restore the skin barrier, especially useful for dry or compromised skin
Well-tolerated by most skin types and unlikely to irritate sensitive skin
Affordable and effective for managing xerosis (very dry skin) and conditions like eczema or psoriasis
Potential concerns
May feel heavy or greasy on some skin types, particularly oily or acne-prone skin
Can potentially clog pores in sensitive individuals, though this is rare
Some consumers prefer to avoid petroleum-derived ingredients for environmental or ethical reasons
Science: Recent dermatological literature confirms paraffin is a gold-standard occlusive emollient recommended by dermatologists as first-line treatment for dry skin and barrier dysfunction. It works by preventing transepidermal water loss and is considered safe and effective for long-term skincare management, including in vulnerable populations.
