How to apply hair removal cream on pubic area?

Could you please elaborate on the proper steps to safely apply hair removal cream in the pubic area? I'm particularly interested in understanding the precautions to take to avoid skin irritation or any potential allergic reactions. Would it be advisable to conduct a patch test first? Also, how long should the cream be left on for optimal results, and what is the recommended post-application care routine to ensure smooth and healthy skin? Additionally, are there any specific brands or types of hair removal cream that are better suited for this sensitive area? Thank you for your guidance.
