The pads are just a semi-abrasive (i.e. exfoliating in texture) cotton mix pads, so without the solution, which you pour over the pads before using for the first time, there wouldn't be any benefit to the pads themselves. You shouldn't have solution left over if you follow the directions and pour the entire bottle of solution over the pads; that said, since you do have solution left over, just buy some regular drugstore cotton pads and use those to apply the solution.
As for whether you need to apply moisturizer on top after applying the solution-soaked pads, I think that's dependent on your skin type and, more importantly, how your skin feels a few minutes after the solution has dried on your skin. If your skin feels at all tight or irritated or dry, then by all means apply a moisturizer afterwards. If your skin feels fine after application, you don't need to apply moisturizer on top, unless you want to. The solution contains a ton of great ingredients so your skin isn't lacking in needed nighttime treatments beyond this, but again, if your skin feels tight or dry after application, a moisturizer isn't going to keep the solution's ingredients from working properly. Just don't use a moisturizer containing retinol since the solution has a lot of retinol in it already and you don't want your skin to become irritated from too much retinol.

You get 60 pads, and it's worth the money .. very good on sensitive skin and skin that cannot handle a retinol.

hi Laurie - I'd think that you'd probably want to alternate the 2 products; so use one on Monday and the other on Tuesday, etc. I personally love the Miracle Worker retinoid pads and have ditched Help Me since trying them - but everyone's different. Depending on your skin's sensitivity to retinol you might find that you prefer one product to another. Good luck!
