I’ve loved working with the Spa doctor products! They feel so good on my skin! My favorite part is that I know the products are healthy and safe for my skin.
Dr. Terra Winston Naturopathic Physician
As a Naturopath...these are a YES!
As a Naturopath, I am always looking for clean non- toxic products that my patients can trust and that won't disrupt their hormones. Toxic products play such a huge role in hormone imbalances. Not only do I love the products, but they work so well and I've noticed a big difference in my hair (LOVE the hair mask) and skin (so hydrated and healthy). As someone who is also in perimenopause I value the clean ingredients. I will be carrying these in my clinic :)

I love their products, esp the Age-Defying Skincare system. It's a great go-to all-in-1 pack for beginning skincare enthusiasts. I have dry skin and the Facial Boost (#4) is my favorite. I am a naturopathic doctor and I've been a fan of Dr. Trevor Cates since my time as a med student.

It’s the only one I kept using

I’ve tried so many serums that ended up half-used in a drawer. This one felt different from the start and I actually saw a change. I’m on my third bottle.

Yes. All our skincare products are non-comedogenic.

I have sensitive skin, is it safe for me to use this?
