An esterified vitamin A that has better stability and, according to studies, works just as well as retinol in anti-aging and acne-reducing products. It speeds up skin cell regeneration and boosts collagen production.

Retinyl propionate is an esterified form of retinol (you can read more about it here).
Retinoids are a large group of ingredients with vitamin A-like activity (to put it briefly). Retinoic acid is the active form, while others like retinol, retinyl palmitate, and, of course, retinyl propionate, have to first be transformed in the skin cells into the active form. Retinoids have powerful collagen boosting, anti-aging, and anti-acne properties, although some people don't tolerate them well and they are quite unstable when exposed to air, heat, and light.
Retinyl propionate is one of the less used, but very promising, retinoids. A clinical study from 1998 reported only minimal trends towards anti-aging skin improvements after using a 0,15% RP cream for more than 24 weeks. That was not very promising, but what they did notice was that all signs of actinic keratosis had disappeared (a scaly spot caused by sun damage).
Two newer studies follow up on this: one test-tube study reports that RP is effectively utilized by skin cells, while another test-tube study reports that while pure RP is effective at stimulating collagen production, it works even better when combined with other antioxidants and niacinamide.
Other studies seem to agree – there are clinical tests with skincare products that combine RP with climbazole, niacinamide, and peptides, and a whole range of different ingredients, with good anti-aging results and less irritation. These also agree that the concentration of RP used should be 0,3%.
Lastly, RP appears to be more stable in a skincare formula than regular retinol. Overall, it is a promising retinoid that seems to be better tolerated and easier to work with.
Either way, it is important to always remember to include sunscreen in your retinoid skincare regime!
