Aloe vera: what science confirms, and what it does not
By Jeremy Fain, founder of Restelys. Updated 17 October 2026. 2 sources cited.
Aloe vera is everywhere. Its real effects are more modest than its reputation, but they exist, and that is what counts.
Aloe vera gel, taken from the heart of the leaf, is mostly water, polysaccharides and minerals. Studies confirm a moisturising and soothing effect on irritated skin, notably after sun exposure.
On the other hand, many of the virtues attributed to it rest on laboratory work or small studies. So we will not tell you it works miracles: it brings softness and hydration, and that is why we chose it.
This caution is a rule for us: an ingredient only enters our specifications if its benefits are documented, and we never claim more than the studies allow.
