Under-watering:
The soil will be completely dried out and the leaves on the succulent (especially near the bottom of the plant) will begin to wrinkle. This means the plant is low on water and rehydrating with the water stored in its leaves. Water modestly and the wrinkling should fix itself in about a day or so!
Consequently, how do you save a shriveled succulent?
Dig the succulent out of the soil and remove excess soil stuck to the roots, cut off any brown/black roots as these are rotten already. Leave the plant on a mesh or any kind of strainer till the roots have air dried from anywhere two to three days. When the roots are dry completely, plant them back in the pot.
Also know, what happens when succulents get too much sun?
When succulents are getting the right amount of sun they’ll often “blush” or change colors. This is such a beautiful transformation to see! If they start to get too much sun however the leaves will actually burn. You may begin to notice white or pale patches on the succulent leaves.
