Zestra® Female Arousal Fluid 3 packets / 0.8ml each. Better Sex, Effortlessly. The good news is that as women age, they often feel better about who they are. The bad news is that, sometimes, our bodies don’t respond the way they used to. That’s because declining levels of the estrogen lead to decreased vaginal lubrication and less vaginal elasticity, and lower androgens can diminish desire and arousal. Recommended by doctors, Zestra® is a safe, natural, easy-to-apply blend of botanical oils and extracts that works by heightening a woman’s sensitivity to touch. So you feel more during sex. Experience the Zestra Rush™ within minutes the first time — and every time — you use it.
