Thank pdeco.I think I am experiencing shedding after a week only. The bumps diminish slowly but the hyperpigmentation is still there. I still have a few questions, though.
1. I once had laser a year ago in Indonesia using the same machine but never went back. I noticed that the hair was reduced but some hair were still growing. Probably 60-70 hairs. Do you think that in the laser treatment I had last week would kill these remaining hairs and will not grow again?
2. The speed of my upper lips hairs growth are like of those men's. I used to shave or pluck everyday. So, wouldn't 4 weeks interval is enough for another treatment?

Everyone's body is different, go in for your next treatment about 1-2 weeks after you see new growth. Four weeks may be too soon. Shaving is fine but plucking will cause stronger regrowth. If the remaining hairs you have are dark and coarse, LHR can treat them.

You need 6-8 treatments spaced about 8-12 weeks apart for permanent results because hair grows in cycles. So what you see at one point is not all the hair you actually have, but a portion of it. Each treatment kills a certain percentage of all the hair you have. If you only had one treatment before, you probably killed some of the hair. You'll still need at least 4-5 treatments for most of the hair you still have to be gone.

PSF is not recommended for darker skin, as there is no cooling used with it. Also, the settings used are important. If you can give us that information, we can be of further assistance.

Thank you! I will ask what setting they use on me next time I am in the clinic.

I would call and ask for settings, so next time you come prepared.

So guys, can I use Hydroquinone while still on the laser treatment? I still have 5 laser treatment to go on my upper lips and I am planning to use Hydroquinone to get rid of the hyperpigmentation on my uppser lips. Or should I wait until I am done with the whole laser treatment?

I would consult your clinic and your dermatologist. Also, I would make sure they don't use the PSF on you anymore to avoid more pigmentation.

Thank you Lagirl. I will make sure they don't use PSF on me on my next treatment.

I finally used Hidroquinone mixed with tretinoin for the hyperpigmentation and the result is very satisfying. Here's the picture after 2 weeks of applying the cream every night:
