Repair tired skin overnight with a retinal night cream and glycolic acid cleanser, your secret to a brighter, smoother face.
If your face could talk, it would probably beg you for a good night’s sleep and a solid skincare routine. Between late-night doom scrolling, work stress, and Netflix marathons, your skin’s overnight recovery can take a real beating. That’s where the magic happens or doesn’t. Sleep and stress play a massive role in how your skin looks, feels, and functions. Luckily, the right skincare can help it bounce back.
Absorption of light allows 11-cis-retinal to relax from a bent shape (arising from the cis double bond) to a lower energy, all-trans arrangement. The straighter all-trans-retinal can no longer fit in the receptor designed for 11-cis-retinal and is ejected. This change leads to differences in cell membrane potential and, as ions are pumped into the cell, this response turns into a nerve impulse that travels to the brain. That is not the end of the matter; the all-trans-retinal generated by this process is reconverted to 11-cis-retinal by specific enzymes, which can re-bind into the receptor, ready to interact with another photon of light.

Dotting the Eyes
Peering into a medaka fish’s eye, scientists look for clues to how are own vision develops. On the left, tiny dot-like stem cells in the neural retina develop into the distinctive dome of the eyeball. Some cells are genetically engineered to produce green fluorescence – so generations of dividing cells appear as stripes which fan out as the eye grows. On the right, a mathematical model mimics these developmental patterns, but also makes a prediction. For healthy growth, the neural retinal cells must send signals to their neighbours in the retinal pigment epithelium, helping these two layers of the eye to develop at the same rate – too slow might produce a wrinkled eyeball and loss of vision; out of control division might lead to cancer. Investigating such close relationships in other tissues, and in other species like humans, may reveal how cellular communication breaks down causing disease.
