The Summary (TL;DR)

Many skincare products—even “clean” or expensive ones—contain ingredients that clog pores and trigger acne. Common culprits include coconut oil, lanolin, and synthetic dyes. This post breaks down the top 10 acne-causing ingredients, explains what to look for on labels, and how to use ChekIt to scan product lists automatically. We also share a few lifestyle tweaks to help prevent breakouts from the inside out.

Why Ingredients Matter (More Than You Think)

If you’re struggling with breakouts—or helping clients who are—it’s not just about hormones or stress. Products play a huge role. Even “non-comedogenic” items can contain hidden pore-cloggers, especially when misused or layered incorrectly.

🚫 The Top 10 Ingredients That Can Cause Acne

These are some of the most common offenders found in everything from moisturizers to SPF:

1. Isopropyl Myristate

→ Ultra comedogenic. Found in lotions and primers. Smooths texture but clogs pores like crazy.

2. Coconut Oil

→ Natural, yes. But it has a comedogenic rating of 4 — not ideal for acne-prone skin.

3. Lanolin

→ Derived from sheep’s wool. Often in creams and balms. Occlusive and likely to clog pores.

4. Algae Extract (various types)

→ Found in “clean” or spa products. Sneaky trigger for some acne-prone users.

5. Wheat Germ Oil

→ High vitamin E content, but it ranks a 5 on the comedogenic scale. One of the worst.

6. Laureth-4 / Laureth-23

→ Common emulsifiers and surfactants. These show up in face washes and serums.

7. D & C Red Dyes (especially Red 30, Red 36)

→ Found in blush, lipstick, and tinted skincare. Can cause breakouts, especially around the cheeks.

8. Ethylhexyl Palmitate

→ Common in cream makeup and moisturizers. Comedogenic rating of 4.

9. Fragrance (Parfum)

→ Can irritate sensitive skin and trigger inflammation that worsens acne.

10. Silicones (Dimethicone, Cyclopentasiloxane)

→ Not always bad, but in some users they can trap oil and bacteria, especially if not removed properly.

😩 Why Figuring Out Acne-Causing Ingredients Is So Hard

Here’s why you keep seeing “breakouts” from new products — even the ones that say non-comedogenic or clean:

  • The term “non-comedogenic” is not regulated
  • Many acne-causing ingredients have innocent-sounding names
  • Ingredient lists are long, confusing, and often full of hidden triggers
A product may look beautiful, be backed by influencers, and still include:
  • Isopropyl Myristate (Rating: 5 – yikes)
  • Coconut Oil (Rating: 4)
  • Algae Extract (sneaky pore-clogger)
  • Red Dyes (D&C Red 30, etc.)
  • Fragrance or “Parfum” (irritating AF)

Why It’s Hard to Spot Comedogenic Ingredients

They hide behind scientific or botanical names — and sometimes seem skin-friendly!

Examples

Common Name: Coconut Oil

INCI Name: Cocos Nucifera

Comedogenic Score: 4–5

Common Name: Wheat Germ Oil

INCI Name: Triticum Vulgare

Comedogenic Score: 5
