How to treat hyperpigmentation from cyrosurgery?

For hyperpigmentation scars, I would suggest Melarase AM and Melarase PM creams followed by light chemical peels and fractional laser. Best, Dr. KaramanoukianLos Angeles

This will lighten over time but a purple concealer will decrease the appearance. If it persists a medium vi peel or a q switched yag laser can lighten or eliminate the problem

Hyperpigmentation will usually get better over time.  I would recommend daily use of sunscreen.  In addition to this you can apply a prescription strength topical hydroquinone cream.

To properly answer your question it would be very helpful to know your skin type. it is more difficult to lighten post inflammatory hyperpigmentation  in darker skin individuals. Also, I would like to know the percentages of each of the ingredients of the triple bleaching cream that you were given and what you were washing your skin with. Are you using a moisturizer? Which one?there are many skin lightening products that can work with time. Some have hydroquinone or kojic acid alone or in combination. Others have that same combination with higher doses of hydroquinone. Tretinoin may be added to hydroquinone and a topical steroid such as triamcinolone can also be an effective addition.Whatever your skin type is it will take time to get good results.

Give it timeUse a high factor SPF 50Plus sunscreenUse a fading agent such as HQ by itself (not a combination cream), or dilute your current cream Consider Low energy Q switch 1064 laser CheersDr Davin Lim Laser and aesthetic dermatologistBRISBANE, Australia.
