Slightly old thread, I know, but I'm feeling embarrassed about my crepey arms too now that the good weather is coming and it will be difficult to keep them covered. They seem to have got worse very quickly this winter but, at 73, I suppose it's normal. I'm slim built and go to the gym three times a week for weights/resistance exercises and do Pilates or a stretch class 3 times a week. The weights really tone up the muscles which is gratifying but don't do anything for the skin when the elasticity has gone. Same over the rest of the body - it doesn't matter how well toned the muscles are, if the skin has lost its elastin and collagen, you're stuck with old-looking arms/legs/tummy etc. Moisturising daily helps slightly but not a lot! If anyone knows any miracle creams that don't cost a bomb, please let me know!
