Creams to improve crepey skin on neck and chest

[TheRoaringGirl]

Do they exist? Ones that work anyway. My neck resembles an accordion and my post-breastfeeding boobs look like unfilled sausage skin at the top. Normal moisturiser isn't cutting it. Help! Low-mid range ideally budget-wise

Prai Ageless Decolletage Cream. Was recommended on here and I rate it. Marks and Spencer do small pots I think.

Anything with hyaluronic acid for a quick fix (it improves appearance immediately), and anything with good old glycerine too

Both help draw/keep moisture back into dehydrated skin

Just looked it up and main ingredient in Prai is glycerine

Thanks!
