Why doctors trust Pipa: experts, testing and the founder

Pipa Skin Care is skincare made intentionally for kids and tweens ages 8 to 13. Every core formula has passed an independent, dermatologist-supervised patch test, every formula is free from fragrance, hormone disruptors, parabens, sulfates and phthalates, and the line is recommended by a board-certified dermatologist, a pediatrician and a board-certified plastic surgeon — all three of them parents. This page lists exactly what that means, with names, numbers and dates.

What the experts say

As a dermatologist — and as someone who understands how overwhelming the world of skincare can be — I believe every young girl deserves a safe, simple place to start. That's why I wholeheartedly recommend Pipa.It's gentle, dermatologist-tested, and free from harsh ingredients like parabens, sulfates and synthetic fragrance. More importantly, it's designed to support healthy skin without adding pressure to follow every new trend.In a time when social media can make girls feel like they need complicated routines or dozens of products, Pipa offers something different: a trustworthy way to care for your skin that encourages confidence in young kids. Pipa is a brand I trust.

Francisco Kerdel, MD

Board-certified Dermatologist, Miami, Florida

Pipa products are teen-friendly and doctor-approved — which means I feel totally confident recommending them to patients and using them for my own daughter. The routine is simple, smart and age-appropriate.

Lisa Klein, MD

Pediatrician, author, and co-founder of Turning Teen

As a mom of two young girls, I wanted to offer a line that I felt comfortable bringing home to my own kids. The age-appropriate products and safe ingredients made Pipa a perfect fit.

Independently tested: the clinical studies

In 2025 Pipa commissioned Repeated Insult Patch Tests (RIPT) — the standard test for whether a leave-on or rinse-off product irritates skin or causes an allergic sensitization — for each of its four core formulas. The tests were run by Eurofins | CRL, Inc. in Piscataway, New Jersey, an independent clinical research laboratory, under principal investigator Winston Moy, MD, Diplomate of the American Board of Dermatology. Each study enrolled 120 volunteers with self-perceived sensitive skin; 113 completed the full nine-application induction phase and the challenge phase.

Conclusion of each report, in the laboratory's words: under the conditions of the study, the test material "did not demonstrate a potential for eliciting dermal irritation or inducing sensitization." The studies were conducted under the laboratory's standard operating procedures and applicable ICH Good Clinical Practice standards, with written informed consent from every participant.

What clinically-tested means at Pipa

It means a board-certified dermatologist supervised a controlled test of the finished product on human skin, and the results are documented in a signed report. Patch tests of this kind are run on adult volunteers; children are, as a rule, not enrolled in cosmetic safety studies. That is why Pipa tests on adults with sensitive skin — the closest available model for young, thinner skin — and why the formulas leave out the ingredients that most often cause trouble on young skin in the first place. Study reports are available to retailers, pediatricians and journalists on request at hello@pipastics.com.

Meet the founder

Kristina Kubler is a licensed esthetician with more than ten years in the beauty industry, and a mother of three. Born in Venezuela, she studied business, worked as a professional makeup artist and specialized in skincare after moving to the United States. When her daughter — whose nickname gave the brand its name — asked for skincare, nothing on the shelf fit: adult products were too strong, and products marketed to kids were not effective.

So she set out to build something different: a line made specifically for ages 8–13, with gentle, age-appropriate formulas and no harsh actives. Every product is dermatologist-tested before it ever reaches a shelf.

Curious why a licensed esthetician created a skincare line just for tweens?

Questions parents ask

Is Pipa really tested by dermatologists?

Yes. Squeaky Clean, Glow Go, Smooth Operator and Sun-Sational each passed a Repeated Insult Patch Test at Eurofins | CRL in 2025, supervised by board-certified dermatologist Winston Moy, MD. A dermatologist in private practice, Francisco Kerdel, MD, recommends the line independently.

Is Pipa pediatrician-approved?

Pediatrician Lisa Klein, MD, co-founder of Turning Teen, recommends Pipa to her patients and uses it with her own daughter. Pipa's formulas were developed in consultation with pediatricians. Pipa does not claim endorsement by any medical association.

Was Pipa tested on children?

Cosmetic safety studies of this kind are run on adults, and Pipa's were too. The formulas were tested on 113 adults with self-perceived sensitive skin per product, and are designed for ages 8–13 by leaving out fragrance and adult actives. If your child has eczema, allergies or very reactive skin, patch-test on the inner arm for 48 hours and check the ingredient list with your pediatrician.
