The full read
RCTs show significant increases in lash length, thickness, and darkness by week 16. Side effects to know: possible iris darkening (rare, permanent), periorbital fat atrophy with prolonged heavy use, and lid pigmentation (reversible). Prescription route is safer than gray-market 'lash serums' with undisclosed analog doses.
