Did you know that by purchasing your homecare from your G2O service provider, you are helping to generate opportunities for their continued training and education? With your Yon-Ka Paris purchase at G2O, you are helping our estheticians earn a trip to Paris in 2026 to tour their facilities and have a private audience with the matriarch of the company, who is always eager to hear feedback about their product. Help our incredible team get to Paris, and they will be taking your feedback with them.
*In order to qualify for the 20% discount on Yon-Ka, the Signature Facial must be received during the month of August 2025. This does not apply to other types of facials, nor to any appointment booked in August for a date outside of August. This only applies to Yon-Ka.
