I have fine wrinkles and uneven skin texture, so I'm thinking of trying retinol. Will it actually be effective?

Recently, fine wrinkles around my eyes and mouth have become more noticeable, and my skin texture has become rough, so I'm considering retinol products.

I looked it up and it said that it would be good to gradually increase the concentration, but I have no idea how much redness or stinging it would actually cause.

I have sensitive skin, so I'm worried that mixing it with other ingredients might cause problems, and I'm also curious about how to best incorporate it into my routine.

Those who have experience using it, please tell us honestly about the actual effects, the degree of skin changes, and the recovery period.

If you are an expert, it would be helpful if you could tell me the recommended concentration, usage cycle, and precautions.

As someone who is using it for the first time, I would like to hear about your experiences to what extent it is possible to improve fine wrinkles and improve skin texture without side effects.
