JO, also known as System JO, is a U.S. brand founded in California in 2003 that specializes in lubricants and intimate care products. Its key feature is clearly separated formulas — water-based, silicone-based, and hybrid compositions — which let you choose the exact glide and staying power that best fits a specific situation; an extra advantage is subtle scents and fragrance-free versions for sensitive skin. JO is especially appreciated by those who want a reliable, smooth feel without stickiness and products that work equally well for solo moments and with toys. The range includes lubricants of different thicknesses, massage products, and specialized gels, making it very easy to find the right texture and sensation.
