Shaved bikini line for the beach. Totally embarassed by bumps. What can I do about razor burn?

Laser. People who get irritation and razor burn in the bikini line often struggle with this problem for a long time before finally deciding to do laser hair removal. If this is your problem, laser hair removal is likely the most effective option. The upfront cost is significant, but the relief can be life changing.
Razor burn. Insure you use fresh, sharp blades vice dull blades. If hair is > several mm long – then trim before shaving. Wash area before shaving – warm water helps to soften hair. Use a lubricant when shaving. Avoid using products that contain alcohol or are scented. Shave in direction of the hair – not against it. Be gentle when shaving – don’t push down too hard. Moisturize skin after shaving.
