What Ingredients Should NOT Be in Your Skincare Products

Choosing the right skincare products is paramount to pursuing healthy, radiant skin. However, not all ingredients are created equal; some may do more harm than good. At Premier Dermatology, our board-certified dermatologist in Delaware is committed to helping clients make informed decisions about their skincare routines. In this guide, we’ll highlight some common ingredients that should be avoided in skincare products to protect your skin’s health and vitality.

Avoid These Ingredients

According to our dermatologist in Newark Delaware, never buy skincare products that have the following ingredients:

  • Parabens
  • Sulfates
  • Synthetic Fragrances
  • Mineral Oil
  • Formaldehyde-Releasing Preservatives
  • Aclohol


Parabens are synthetic preservatives commonly found in skincare products to extend shelf life. However, research has raised concerns about their potential link to hormone disruption and other health issues. Our dermatologist in Delaware says to opt for paraben-free skincare alternatives to safeguard your skin and overall well-being.


Sulfates, such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), are foaming agents often used in cleansers and shampoos to create lather. While sulfates effectively remove dirt and oil from the skin, they can also strip away natural oils, leading to dryness, irritation, and sensitivity. Look for sulfate-free options to maintain a healthy skin barrier.

Synthetic Fragrances

Fragrances are added to skincare products to enhance the sensory experience, but synthetic fragrances can contain a cocktail of potentially harmful chemicals. These artificial fragrances may trigger allergic reactions, irritate sensitive skin, and exacerbate conditions like eczema and rosacea. According to our dermatologist in Newark Delaware, it’s best to opt for fragrance-free or naturally scented products to minimize the risk of irritation.

Mineral Oil

Mineral oil is a common ingredient in moisturizers and skincare products due to its emollient properties. However, mineral oil is derived from petroleum and can create a barrier on the skin’s surface that traps moisture prevents the skin from breathing and eliminates toxins. Choose plant-based alternatives like jojoba oil or shea butter for nourishing hydration without clogging pores.

Formaldehyde-Releasing Preservatives

Formaldehyde-releasing preservatives, such as DMDM hydantoin and quaternium-15, are used in skincare products to prevent bacterial growth and extend shelf life. However, these preservatives can release formaldehyde, a known carcinogen, and skin irritant upon contact with water. Look for products labeled as formaldehyde-free to minimize exposure to this potentially harmful ingredient.


Alcohol, particularly denatured or drying alcohols like ethanol and isopropyl alcohol, is often used in skincare products for its astringent properties. While alcohol can help to temporarily degrease and mattify the skin, it can also strip away natural oils, disrupt the skin’s moisture barrier, and lead to dryness and irritation. Opt for alcohol-free formulations to maintain balanced, healthy skin.
