Our Lemon Thyme Facial Tonic HydroSoul is 100% fresh plant material and nothing else. It is distilled in alembic copper at low temperatures over three to four hours. This slow, labor-intensive artisan process creates a vitalizing and energetic HydroSoul, offering subtle, aromatic hydration for all skin conditions. In contrast, conventional distillation uses stainless steel and high temperatures, the entire process lasting approximately forty-five minutes.
