Our Story
Meet the acne brand that bridges internal and external skincare through supplements and topicals with no-pore clogging ingredients, ever.
It all started with two women determined to take their acne into their own hands.
Danielle struggled with severe acne—and many failed treatment attempts—for years before clearing up her skin by extensively researching the causes of acne and becoming a Licensed Clinical Esthetician.
In 2014, she founded The San Diego Acne Clinic, where she earned the title of The Acne Guru® due to her astonishing 98% success rate in clearing her patients’ skin across all ages, ethnicities, and skin types.
Among her success stories is Kayleigh Christina, an Integrative Health Practitioner + Nutritionist who couldn’t clear her cystic acne until visiting Danielle at her clinic and adopting her approach.
Their shared passion for wellness and transformation inspired them to create CLEARSTEM together to help more people achieve the skin they could previously only dream of.
CLEARSTEM is a labor of love, here to empower you with internal + external solutions for your skin. We’re so glad you’re here!
