Why Ingredient Awareness Matters

Not all skincare ingredients are created equal. Some can cause irritation, sensitization, or even long-term skin damage. Understanding which ingredients to avoid can help you make informed choices and maintain healthy skin.

Ingredients to Avoid

Harsh Sulfates

Common names: Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES)

These aggressive cleansing agents can strip the skin's natural protective barrier, leading to dryness, irritation, and increased sensitivity.

Better alternatives: Coco-Glucoside, Decyl Glucoside, or Sodium Cocoyl Isethionate

Parabens

Common names: Methylparaben, Propylparaben, Butylparaben, Ethylparaben

These preservatives can disrupt hormone function and may cause skin sensitization in some individuals.

Better alternatives: Phenoxyethanol, Ethylhexylglycerin, or natural preservatives like Rosemary Extract

Formaldehyde Releasers

Common names: DMDM Hydantoin, Quaternium-15, Imidazolidinyl Urea

These preservatives release formaldehyde, a known carcinogen that can cause skin irritation and allergic reactions.

Better alternatives: Potassium Sorbate, Sodium Benzoate, or plant-based preservatives

Synthetic Fragrance

Look for: "Fragrance," "Parfum," or unlisted fragrance compounds

Can contain hundreds of undisclosed chemicals that may cause allergic reactions, skin sensitization, and respiratory issues.

Better alternatives: Essential oils (in small amounts), fragrance-free products, or natural extracts

Denatured Alcohol

Common names: Alcohol Denat., SD Alcohol, Isopropyl Alcohol

These drying alcohols can disrupt the skin barrier, cause irritation, and lead to increased oil production as skin overcompensates.

Better alternatives: Fatty alcohols (Cetyl, Stearyl Alcohol) or alcohol-free formulations
