Shelby Sumner

Shelby Sumner is a registered Clinical Nutritionist (BHs, ANTA), Holistic Skin Therapist and founder of SKNbyShelby, a holistic nutrition clinic specialising in skin conditions.

Combining her clinical expertise with the personal experience of chronic acne, Shelby brings a compassionate approach to her work. Her philosophy is grounded in the understanding that skin health is a reflection of internal balance, with particular focus on the gut-skin axis, hormonal influences, and nervous system regulation.

Having worked closely with clients navigating chronic skin conditions, such as acne, eczema, dermatitis, and topical steroid withdrawals, Shelby understands the emotional and psychological impact that skin concerns can have. She is particularly passionate about helping individuals move away from restrictive, fear-based approaches to food and skincare, and instead build sustainable, nourishing habits that support long-term skin health.

Shelby’s work integrates corneotherapy principles, having a barrier-first approach, with personalised nutrition and lifestyle interventions, allowing her to support the skin both topically and systemically.

Outside of clinic, Shelby prioritises the same foundations she teaches - regular movement, a balanced whole-food approach to nutrition, and of course prioritising fun. Her work is driven by a commitment to empowering clients with the knowledge and tools to achieve resilient, healthy skin from the inside out.
