  One remaining open question regarding the physical properties of Ly$\alpha$
emitters (LAEs) is their dust content and its evolution with redshift. The
variety of results is large and with those reported by now is difficult to
establish clear relations between dust, other fundamental parameters of
galaxies (star-formation rate, metallicity or age) and redshift. In this
Letter, we report \emph{Herschel} PACS-100$\mu$m, PACS-160$\mu$m and
\emph{Spitzer} MIPS-24$\mu$m detections of a sample of spectroscopically
GALEX-selected LAEs at z$\sim$0.3 and $\sim$1.0. Five out of ten and one out of
two LAEs are detected in, at least, one PACS band at z$\sim$0.3 and $\sim$1.0,
respectively. These measurements have a great importance given that they allow
us to quantify, for the first time, the dust content of LAEs from direct FIR
observations. MIPS-24$\mu$m detections allow us to determine IR properties of
the PACS-undetected LAEs. We obtain that mid-IR/FIR detected star-forming (SF)
LAEs at z$\sim$0.3 have dust content within 0.75$\lesssim$ $A_{1200\AA}$
$\lesssim$2.0, with a median value of A$_{1200\textrm{\AA}}$$\sim$1.1. This
range broadens out to 0.75$\lesssim$ $A_{1200\AA}$ $\lesssim$2.5 when
considering those LAEs at z$\sim$1.0. Only one SF LAE is undetected both in
MIPS-24$\mu$m and PACS, with $A_{1200\AA}$ $\lesssim$0.75. These results seem
to be larger than those reported for high-redshift LAEs and, therefore,
although an evolutionary trend is not clearly seen, it could point out that
low-redshift LAEs are dustier than high-redshift ones. However, the diverse
methods used could introduce a systematic offset in the results.
