Onion skin weathering is an ongoing process. How long it would take for a specific rock to completely weather would depend on its size.
Common in exposed granite, it is the exfoliation of the outer layer of the rock due to differences in temperature between the surface and the interior of the rock which eventually leads to fracturing. This happens when a rock is repeatedly heated and cooled. As it is heated , the outer layer of the rock expands slightly and as it cools the rock contracts. Continual expansion and contraction causes small pieces of the rocks surface to peel off just like a skin of an onion Onion skin weathering can also occur from the dissolution of feldspars in granite rock by acidic rainfall, which creates clay minerals. The outer layer of a chemically weathered granitic rock can become crumbly and slough off in layers, typical of onion skin weathering.

The process of weathering can take thousands of years or longer, depending on the type of rock, climate, and other environmental factors. Chemical weathering tends to be a slower process compared to mechanical weathering, which can occur relatively quickly in areas with frequent freeze-thaw cycles or high levels of erosion. Overall, weathering is a gradual process that continuously shapes and changes the Earth's surface over extended periods of time.
The rate at which weathering and erosion occur on rocks can vary greatly depending on factors such as rock type, climate, and the presence of organisms. Weathering and erosion can range from taking thousands to millions of years to significantly alter or break down rocks.
Weathering can occur over both short and long time scales, from a few days to thousands of years, depending on factors such as the type of rock or material being weathered, climate conditions, and the presence of vegetation or water. Chemical weathering can be a slow process, whereas physical weathering can happen more rapidly in response to factors like temperature changes and mechanical stress.
Onion
An onion!
If an onion is wrapped in foil, it can take an hour.
An onion. When you peel off an onion's skin, it may make you cry due to the release of its pungent aroma, but the onion itself cannot cry.

It takes less than 72 hours for an onion to start growing bacteria.
Well, i started a decomposition and we threw an onion in it. It took about 3-8 months, but i'm not really sure.
how long does it take to grow a new layer of skin
500 years
It can take as many years as it needs to. It all depends on what kind of weathering occurs, and how big the grain size is.
A long time.
