Regenerative Longevity Aesthetics™ — evidence-informed protocols for healthier-aging skin and body.
Cathy M. Estrella, MPH founded South County Microspa to give clients a clear, unhurried path through aesthetic care.
She developed the Dual Pathway Regenerative Anti-Aging Model™ and created NeoFusionLift™ and the DermaJeune MD™ skincare collection.
Her work focuses on practical guidance, careful treatment selection, and care that clients can understand and maintain.
The Practice Philosophy
Evidence Over Trend
Protocols and technologies are selected deliberately, with attention to research, comfort, and a client's individual goals.
The Whole Body Matters
Skin care works best when it reflects the larger picture, including recovery, lifestyle, and the realities of everyday life.
Longevity, Not Just Aesthetics
The aim is care that feels considered and remains useful long after a single appointment.
