What others say

Extensive knowledge of the cosmetics industry makes her an exceptional expert and advisor.

I have worked closely with Dr. Theresa Callaghan in the preparation of several publications on the results of preclinical and clinical studies of dissolvable microneedles. As a result, we published two peer-reviewed scientific papers. Since that time, I began to actively seek expert assistance from Dr. Callaghan on the preparation of descriptions, labels, and claims for cosmetic and medical products for compliance with the requirements of EU and US legislation. Exclusively thanks to our cooperation, our company managed to register soluble microcones as cosmetic products in the EU. Theresa's extensive knowledge of the cosmetics industry makes her an exceptional expert and advisor. Discussing the syntax of a paragraph or a claim, she helps to immerse yourself in the depth of the meaning of each thesis, as if you looking at an Aivazovsky painting. On a personal level, it has been easy and enjoyable to communicate with her. No matter how stressful the situation is, she always creates an abode of calm. She is a strong communicator and a trusted colleague.

Combines knowledge (which she has a lot) with creative thinking (ditto)

Theresa has lots of talents but most important of all she combines knowledge (which she has a lot) with creative thinking (ditto). In the projects we worked with her on, she has shown to be extremely professional and detailed in her reports and advice without ever losing sight of the projects timing and deadlines. Truly recommendable.

Impressive market insights

Having worked with Theresa on different projects in different companies, I have always been impressed by her broad knowledge of the scientific aspect of cosmetics and other dermatological products (especially on activity and safety testing), as well her impressive market insights. This unique, and rare, combination of skill have always brought us the information needed to take the right decisions.

This is not a usual thing!

It is really a pleasure that you are teaching on the MSC Cosmetic Science, evidence to that is the interaction and interest from the students! I saw their comments on LinkedIn, this is not a usual thing!

Knows the cosmetics industry inside out

Theresa knows the cosmetics industry inside out and strives to ensure that your product information and claims are justifiable and sound. She is also scientifically curious which helps when designing studies and protocols for product evaluation.

What an honour

Oh what an honour to have Dr. Theresa Callaghan on our Professional Beauty Conference. She has participated in multiple online conferences with us and I am so looking forward to moderating this session on Greenwashing and the new Greenclaims code 2021.
