From Rock Bottom to Running the Industry

I didn’t come from money. I didn’t have investors or a perfect plan. I learned one skill — teeth whitening — and turned it into a business that’s trained over 10,000 pros and reached 70,000+ clients worldwide. 

 

This brand wasn’t built in a boardroom. It was built in real life — between clients, chaos, and crazy faith. Every session, every product, every student represents a piece of that journey.

 

If you’ve ever been the one people doubted… if you’ve ever had to figure it out on your own… welcome home. You’re looking at what “Self Made” really means.

frequently asked questions

What are the benefits of your teeth whitening service?

You’ll see visible results in one visit — no pain, no sensitivity. Our formula safely removes years of stains from coffee, wine, and smoking while leaving enamel strong and healthy.

How should I prepare before my appointment?

Avoid brushing too roughly or eating anything that might irritate your gums beforehand — and honestly, just bring your teeth 😄

Is it safe for sensitive teeth?

100%. We use top-tier cosmetic-grade peroxide gels designed for comfort and effective results, even on sensitive teeth.

With good habits (less coffee, smoking, liquors, more water, and regular touch-ups), your whitening can last longer.

Do I need a license to get certified?

Nope. Our Whitening Pro Certification is open to anyone with a passion for people and a desire to build income in the beauty industry.

Are your products FDA approved?

Teeth whitening gels themselves are not FDA-approved products — the FDA doesn’t classify or approve cosmetic whitening gels. However, our gels are manufactured in FDA-registered and regulated facilities, which means the labs follow all FDA safety, labeling, and quality guidelines.

So while the gels aren’t indi
