How to check your skincare for pore-clogging ingredients?
20-30 minutes max. So worth it., that's how long it took me to go through every product in my routine properly. The amount of research I was doing on active ingredients was counter-intuitive bc I should have been understanding the fillers/inactive ingredients way more. Live and learn I guess! This was my process, not the simplified version:
Pull the full INCI list from each product, NOT just the front label. The front label tells you the marketing story, the INCI tells you what's actually in it. For some products I had to go to the brand website to find this since packaging doesn't always list everything legibly.
Cross-reference against comedogenic checkers. There are a few options online with long databases, ingredient checker tools, brand-specific checkers. They don't always agree with each other, which is its own problem. When I got conflicting results I looked at concentration (position in the INCI list) and erred on the side of caution for anything rating 3 or higher.
A few ingredients worth paying specific attention to: isopropyl myristate (rates a 5, in more products than you'd think), isopropyl palmitate, anything coconut-derived (the derivatives vary widely but many rate high), coconut alkanes, palmitic acid, lauric acid. Some silicones are also worth checking depending on your skin.
One thing I didn't expect going in: the "non-comedogenic" label on the front of a product means nothing. It's completely unregulated, a brand can print it on anything regardless of what's in the formula. Checking the actual INCI is the only way to properly know.
My cleanser had lauric acid. My moisturizer had isopropyl myristate at position six in the ingredient list, that's not a trace amount. My SPF had two coconut-derived emollients. All three had "gentle" or "non-comedogenic" or "for sensitive skin" somewhere on the packaging.
After swapping those out the persistent blackheads I'd been attributing to stress mostly resolved over about six weeks. It started getting noticeably better almost immediately after removing the isopropyl myristate and the one with coconut alkanes ( this was in my Rhode glazing milk so I was SO sad).
