Our Wellness Lounge

We are thrilled to announce that Skin by Cynthia, Lash St. Helena, and Napa Valley Collective Permanent Jewelry + Charm Bar are joining forces to open a brand-new wellness lounge! As sisters and passionate entrepreneurs, we're dedicated to creating a luxurious, comfortable experience for all our guests.

About Me

Hi Welcome! I'm Cynthia, Esthetician, Certified Acne & Sensitive Skin Specialist, and the owner of Skin by Cynthia. Born and raised in Saint Helena, I returned to Napa Valley after almost 14 years in San Francisco.

My love for skincare, ingredients, and transformative treatments guided me to this industry. With a background in healthcare and a BA from San Francisco State University, I’ve gained invaluable expertise, both administratively and through hands-on experience.

My journey began by helping my sister open her lash and wax business over a decade ago, and from there, I’ve cultivated my skills in local health spas, crafting customized protocols and deepening my knowledge through continued certifications. Every day, I’m inspired to bring beauty, balance, and care to those I serve.

Thank you for choosing us. Todos son bienvenidos. Hablamos español.

Book this session to prepare for any peel, including the upcoming Green Sea Peel. This comprehensive service includes a deep consultation, double cleanse, skin analysis, & may include a patch test.

  • This advanced two-part treatment, strictly utilizes professional Korean skincare, is suitable for all skin types and is ideal for acne-prone & rosacea symptoms. Treatment contains elevated antibacterial properties to combat breakout-causing bacteria, while improving hydration & overall skin appearance. Includes: aromatherapy, double cleanse, skin analysis, extractions, Omega Green treatment, LED light therapy, corrective serums, moisturizer, & SPF. Perfect for those seeking rapid relief & lasting results.

  • This treatment features a carbon dioxide gel and a treatment mask, working together to create the Bohr effect. This occurs when the skin is temporarily deprived of oxygen, triggering red blood cells to rush to the area to deliver oxygen. The result? Increased oxygen boosts collagen production, accelerates healing, and deeply hydrates the skin. Beneficial for most skin types including acne-prone skin. It also provides lots of anti-aging benefits by stimulating collagen production and improving skin elasticity.

  • "My skin feels AMAZING! Such an incredible experience. Cynthia is patient, attentive and has a passion for good skin. Book the appointment... you will not be disappointed!"
