Also a woman is in her 60's but her skin is sagging and she looks extremely old.

Answer

The skin-lifting procedure is haraam. This is also a shaitaani act. The Qur'aan Majeed describes such interference with the natural growth and appearance as acts of shaitaan. Old age is also a blessing. The Hadith describes such old people who emulate young people to be the worst of the people. For that reason it is not permissible to pluck out white hairs. The 60 year old lady should act her age. She is on the verge of the Grave. She should not make herself stupid with attempts to emulate the young.
