ChekIt vs CosDNA: The Best Acne Ingredient Checker for Estheticians

Why Ingredient Checkers Matter for Estheticians

If you're helping acne-prone clients, reviewing product routines, or recommending safe skincare...

🔍 You can’t afford to rely on guesswork or 15-year-old spreadsheets.

Clients are looking to you for clarity and results. And that means you need a smart, branded tool that:

• Gives accurate results
• Educates clients in plain English
• Builds trust and authority for your practice

That’s where the ChekIt vs. CosDNA comparison really matters.

‍

🧬 CosDNA: A Legacy Tool (But It’s Showing Its Age)

CosDNA has been around forever. It lets you look up ingredients and see their comedogenicity, irritation, and safety scores. But for working estheticians, it falls short in some major ways.

🔻 Limitations of CosDNA:

• ❌ Outdated UI that’s hard to navigate during consults
• ❌ No way to paste full product lists for instant analysis
• ❌ No explanation of why an ingredient is flagged
• ❌ Can’t be embedded or shared on your own site
• ❌ Doesn’t match your brand — or help build it
• ❌ No support for synonyms, ingredient variations, or concentration context

It was a solid DIY tool — back when we were all cross-referencing spreadsheets. But your clients expect better now.

ChekIt: Built for Estheticians, Not Just Ingredient Nerds

ChekIt was designed specifically for skincare professionals who need real-time, acne-safe ingredient analysis that works in the real world — fast, branded, and accurate.

‍

Here’s What Makes ChekIt Different:

⭐ Comedogenic Ratings with Explanations

No more vague warnings. Every flagged ingredient shows:

• A comedogenicity rating (0–5)
• An explanation of why it clogs pores or irritates skin
• Whether it’s a concern based on position in the ingredient list

💡 It’s not just what’s in the formula — it’s how much and where it appears.

‍

Concentration-Level Context

ChekIt highlights high-concentration pore-cloggers based on their position in the list — so you can say things like:

“This ingredient is pore-clogging, but since it’s near the bottom of the list, it’s likely in a low concentration and may be less of a concern.”

🙌 Instant client education.

‍

🧠 AI-Powered Ingredient Matching

ChekIt uses AI to identify:

• Synonyms (e.g. “Cocos Nucifera” = coconut oil)
• Derivatives (e.g. “Laureth-4” from lauryl alcohol)
• Misspellings & altered spellings

This means fewer missed flags, more accurate results, and less confusion when clients submit weird ingredient lists.

‍

Clinic-Branded UI

ChekIt isn’t just smart — it looks good on your website.

• Match your clinic’s brand colors and fonts
• Embed it as a form or tool clients can use any time
• Add your logo for a custom-branded experience
• Route traffic to your own site, not a third-party database

It’s not just a tool — it’s a trust-building conversion machine.

‍

Designed for Consults and Client Self-Audits

Whether you’re reviewing routines mid-treatment or want to empower your clients between visits:

• Use ChekIt live during your consults
• Share a link so clients can self-check before buying
• Add to your Shopify store for customers browsing your acne-safe line
