Unlike conventional beds where you see fairly immediate color, the color from HP is more delayed and will develop over 48 hours. It's important not to judge HP by just one session! You need 3-4 sessions over a 7-10 day period to develop a great base, and then once every 10 - 14 days to maintain. You must wait 48 hours between HP sessions.
Overall, our High Pressure bed will give you the deepest and longest lasting tan, and offers the best long term value.
