Understanding Pore-Clogging Ingredients for Clear, Healthy Skin

Updated: Jun 28


Acne Specialist in Kitchener-Waterloo

With the rise of social media, there’s an overwhelming amount of acne "life hacks" and advice that can often do more harm than good. Many of my new clients at Shoreline Glow have been using coconut oil in their skincare routines, only to find their acne worsening, blackheads multiplying, and their skin becoming more sensitive and irritated.


The culprit? Pore-clogging ingredients and inadequate exfoliation routines!

Natural oils like cocoa butter and coconut oil, commonly found in many "organic" skincare lines, can wreak havoc on acne-prone skin. It’s not just these natural products; even professional, natural, organic, and acne-specific skincare products can contain pore-clogging ingredients.


Unfortunately, there is no government agency that oversees the claims skincare companies make about their products. This means any company can label their products as promoting clear skin, even if they contain pore-clogging ingredients.

Even prescription medications aren’t exempt. For example, Retin-A in cream form contains isopropyl myristate, a potent pore-clogger. Many other prescription products also contain comedogenic ingredients. Over-the-counter acne medications and so-called "oil-free" products can be just as problematic.


Adding to the challenge, many hair care products contain sodium laureth sulfate or sodium lauryl sulfate, both of which rank high on the comedogenic scale. Oils like jojoba, olive, and lanolin are mildly comedogenic and can be problematic when combined with other comedogenic ingredients.


Before trying a new skincare or hair care product, it’s crucial to check the ingredients list. Labels like "non-comedogenic," "oil-free," or "won’t clog pores" are not always reliable.


If you’re tired of wasting time and money on products that don’t work, schedule a skincare consultation at Shoreline Glow. Together, we can create a plan to help you achieve clear, healthy skin.


What is the Comedogenic Scale?

The comedogenic scale is a rating system that measures the likelihood of an ingredient to clog pores. The scale ranges from 0 to 5:

  • 0: Will not clog pores.

  • 1: Very low likelihood of clogging pores.

  • 2: Moderately low likelihood of clogging pores.

  • 3: Moderate likelihood of clogging pores.

  • 4: Fairly high likelihood of clogging pores.

  • 5: High likelihood of clogging pores.
