My skin is rough and won't slough off properly after chemical peel and VI peels, why? (Photos)

After about 6 months to maybe a year my skin always goes back to being rough and thick with dead skin and hyperpigmentated even after chemical peels such as vi peel, why ? is my skin heavily damaged from a life in the sun ? none of my family has this problem only me, however !!! i did use generic retinoid one year and its after this my skin is always sun damaged. did it ruin my skin ???
