The Right Balance to support our Intimate Environment

Your intimate area values equilibrium as much as you do to function properly. The vagina produces secretions to regulate and cleanse itself, maintaining a balanced acidic environment. Any interference with this delicate balance can result in the growth of bad bacteria. Yet, many of us don’t know our daily habits can disturb the vagina’s internal and external natural balance.

Some thingsthat can affect the vagina's natural balance include:

Daily life

  • Inadequate feminine hygiene
  • Daily use of panty liners
  • Feminine hygiene sprays
  • Excessive fragrance (from perfumed soap or wash)
  • Dyed and scented toilet paper

Environment factors

  • Humidity
  • Seasonal changes


  • Synthetic underwear
  • Tight clothes (such as skinny jeans and some sports clothing)
  • Harsh fabric softener used for underwear

Health/sexual related

  • Antibiotic treatment
  • Stress or fatigue
  • Poor diet
  • Intense sexual activity (semen is alkaline and affects the vagina’s acidity)
  • Birth control pills

Why Use Intimate Hygiene?

The intimate area is delicate and needs pH-balanced cleansing care.

  • The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic or alkaline. 94% of bar soaps have pH>9
  • The normal vaginal pH is 3.8 to 4.5
  • Normal skin pH – around 5.2 - 5.5
