What results should I expect after the first laser hair removal season of bikini area with soprano laser?

Immediately after your first laser hair removal session, hair will be still visible.  Laser targets hair follicle under the skin, and it will take some time for your body to go through a natural process to push dead hair out. Once the dead hair falls out, you will experience a hair-free period  After first treatment, the hair-free period will be brief.  You will experience longer and longer hair-free periods after each subsequent treatments.  

it is way too early for you to notice a difference.  The bikini area hair is coarser and lasers attack the hair follicles and each cycle new hair follicles grow. You need at least 6 treatment for that area and even then is hair reduction of 75 to 90 percent.  You may need touch ups later. 

It is too early after laser hair removal to see results. Remember it takes 6-9 sessions of laser treatment to reduce 70%-90% of the hair. This is because not all hair is in its active growth phase. Keep up with your treatments to see best results.

It will work. Where the color of the skin is darker, it might take more sessions. Bikini area does well with most lasers and even with IPL.

It is way too early to look at results from LHR. Generally, the settings in the bikini area are less than the underarm area, so results take longer to appreciate. Remember it takes about 6 treatments in most people to get results and these are 75% reduction in hair growth. Touch ups are needed every 6 months.
