Yon-ka is taking over our experience room for a limited time with the Yon-Ka Summer Skin Ritual.

For the duration of this promotion, the Bali Revitalizing Ritual is getting the Summer Skin upgrade, featuring Yon-Ka’s Gommage aux Sucres – Mandarin.

For the same price as the client-favorite Bali experience, each client who books the Summer Skin Ritual will receive their own full-size Gommage aux Sucres – Mandarin to self-apply during the session + take home ($60 Value).

Self-apply the Gommage, from Yon-Ka’s Aroma Fusion line, as you detoxify in the steam of our beautifully-appointed Experience Room, with tranquil music + color therapy to amplify your relaxation. This product combines the exfoliating + moisturizing elements of the standard Bali experience in one single product.

After massaging this sugar scrub from neck to toe to buff away imperfections, utilize the Experience Room’s multiple shower heads. The warm water activates the product to melt into a nourishing milk to hydrate the skin with a silky finish.

For 2-6 people 40 min $75 per person
