Sting-Less HOCI Mist: Clinically Tested With Zero Reactions

  • Clinically Tested
  • Dermatologist Supervised
  • Non-Irritant
  • Hypoallergenic

Sting-Less Rapid Repair Mist is clinically tested for skin safety. We sent it to Evalulab, an independent clinical testing lab, for a Human Repeat Insult Patch Test (HRIPT). This is the standard test for whether a skincare product causes irritation or allergic reactions. Here's what they did and what they found.

  • 52 adults completed the study
  • 0 reactions to Rapid Repair Mist
  • 520 skin readings, every one scored “no visible reaction”

The test

What is an HRIPT?

Skin allergies often don't appear the first time you use something. They build up with repeated use. So this test applies the product over and over, takes a break, and then applies it one more time to fresh skin to see if an allergy has developed.

An HRIPT checks two things:

  1. Irritation

    Does the product cause redness, swelling, or other damage where it touches the skin?

  2. Sensitization

    Does repeated contact cause the body to develop an allergy to it?

Method

How the study worked

  1. 3 weeks

    Repeated exposure

    Rapid Repair Mist was applied under a patch on each participant's upper back 3 times a week for 3 weeks, for a total of 9 applications. Each patch stayed on for 24 to 48 hours. Lab staff checked and scored the skin every time before a new patch went on.

  2. 10–20 days

    Rest period

    No product was applied. This gives the immune system time to develop a sensitivity if the product is going to cause one.

  3. 48 hours

    Challenge patch

    A final patch went on a new, untouched area of skin for 48 hours. Then lab staff removed it and examined the skin. A reaction at this stage is the classic sign of a developed allergy.

How skin was scored

Every reading for Rapid Repair Mist was 0.

Lab staff graded each patch site on a six-step scale, from no visible reaction to severe. Here is where all 520 Rapid Repair Mist readings landed.

Takeaways

What this means for you

What the results show

With repeated contact on healthy skin, across a wide range of ages and skin types, Rapid Repair Mist caused no irritation and no allergic response.

What the results don't show

  • No test can guarantee that nobody will ever react. Anyone can be sensitive to any ingredient.
  • If you have sensitive skin or known allergies, try a small area first.
  • Always follow the directions on the bottle.

Questions

FAQ

What does “clinically tested” mean for Rapid Repair Mist?

Rapid Repair Mist went through a supervised clinical study at an independent lab. 55 adults enrolled, 52 completed, and a dermatologist oversaw the results. The study tested for skin irritation and allergic reactions, and Rapid Repair Mist caused neither.

Who ran the test?

Evalulab Inc., an independent clinical testing lab in Quebec, Canada. A dermatologist, Dr. Michel Journet, M.D., F.R.C.P.(C), supervised the study and signed the report's summary.

What does “hypoallergenic” mean here?

It's the lab's conclusion based on the study: no participant developed an allergic reaction to Rapid Repair Mist. There's no single federal standard for the term in the U.S., so we're showing you the actual data behind it.

Was this a test of how well Rapid Repair Mist works on damaged skin?

No. An HRIPT tests whether a product is gentle on healthy skin. It measures irritation and allergy potential, not results on wounds or irritated skin.

Can I see the full report?

The original lab report lists personal information about the people who took part in the study, so we don't share copies of it. We created this page to show you the results while protecting the privacy of everyone who participated.
