10 Toxic Ingredients Hiding in Your Skincare (and What to Use Instead)

I've always been one to take a hard look at the labels of commercial products (both food and toiletries). It's gross. I thought it was gross back then and I still think it's gross now. Behind the clever marketing and clean packaging are ingredients linked to hormone disruption, irritation, and long-term skin damage.

If you’ve ever wondered what might be lurking in your bathroom cabinet, this post is for you. I could go on forever about this but I'll attempt to be concise.

Let’s break down 10 ingredients to watch out for—and what to use instead.

1. Parabens (Methylparaben, Propylparaben, etc.)

Why it’s harmful: Parabens are preservatives linked to hormone disruption and have been found in breast tissue.

Use instead: Natural preservation with essential oils like frankincense and sandalwood offers antimicrobial benefits without the risk.

2. Synthetic Fragrance (“Fragrance” or “Parfum”)

Why it’s harmful: This one word can represent hundreds of undisclosed chemicals—some of which are allergens or endocrine disruptors.

Use instead: Choose products scented only with pure essential oils like rose, lavender, or vanilla—clearly listed on the label.

3. Sulfates (Sodium Lauryl Sulfate, SLS)

Why it’s harmful: Harsh foaming agents that strip your skin’s natural oils, leading to dryness, irritation, and breakouts.

Use instead: Try handmade bar soaps formulated with saponified plant oils like olive and coconut that cleanse gently and effectively.

4. Phthalates

Why it’s harmful: Often hidden in “fragrance,” phthalates are linked to developmental and reproductive toxicity.

Use instead: Again—pure essential oils only. At Elizabeth Scientific, we never hide ingredients under vague terms.

5. Formaldehyde-Releasing Preservatives (like DMDM Hydantoin)

Why it’s harmful: These ingredients slowly release formaldehyde over time—yes, the same chemical used to preserve tissue samples.

Use instead: Products with natural preservatives like vitamin E (tocopherol) or botanical extracts.

6. Mineral Oil & Petrolatum

Why it’s harmful: Derived from petroleum, these ingredients can clog pores and create a barrier that traps toxins and bacteria.

Use instead: Use plant oils rich in nutrients—like Sacha Inchi or Apricot Kernel Oil—for breathable hydration your skin can absorb.

7. Triclosan

Why it’s harmful: An antibacterial agent banned in hand soaps but still found in some skincare. Linked to hormone disruption and antibiotic resistance.

Use instead: Natural antibacterials like saffron, lavender, and frankincense support skin health safely.

8. PEGs (Polyethylene Glycols)

Why it’s harmful: Used to soften and thicken products, PEGs are often contaminated with carcinogens like 1,4-dioxane.

Use instead: Use whole botanical oils that don’t require chemical processing to work.

9. Silicones (Dimethicone, Cyclopentasiloxane, etc.)

Why it’s harmful: Silicones create a slick, artificial smoothness—but they trap dirt and prevent skin from breathing.

Use instead: Oils like pomegranate seed or saffron-infused blends provide real softness and glow without suffocating your skin.

10. Artificial Dyes (FD&C Colors)

Why it’s harmful: These synthetic colors are derived from coal tar and linked to allergies and potential carcinogenicity.

Use instead: No dyes, ever. Let nature shine through. Our products get their hues from real ingredients—nothing fake, nothing toxic.

The Bottom Line

Clean beauty isn’t just a trend—it’s a return to common sense. If you can’t recognize the ingredients in your skincare, your skin probably doesn’t either. At Elizabeth Scientific, we use whole, traceable botanicals and lab-tested safety standards. Every product is made from scratch—no shortcuts, no synthetics.

If you’re ready to detox your skincare routine, start with one swap. Your skin—and your health—are worth it.
