Skin by D requires 24 hour advanced notice in order to cancel any service with no charge. Scheduled treatments are reserved especially for you and time is needed to fill your spot with another appointment. If your appointment is not cancelled within this notification period, your appointment is considered confirmed. Any changes or cancellations made after the 24 hour window are subject to 100% charge for each service. Because of this policy, a valid credit card number is required at time of booking. This policy also applies to gift card and certificate holders.
