Low resolution is something that gave headaches to all designers. There is no miracle to diminish this annoying problem, but there are some tips that we can use with Photoshop to salvage this disaster.
1) When enlarging picture:

Navigate to Image > Image Size. At “Resample Image” you can change the type of anti-aliasing used to enlarge and smooth the image. Change it to “Bicubic Smoother (best for enlargement).” By default, Photoshop uses “Bicubic.”

Bicubic Smoother will allow your image to become as near to your raw file as possible. Well, this is what we need for enlarging of our pictures. Though not perfectly identical, but at least not too far from what we need.
2) Improving the details after enlarging image:

Most Photoshop users mostly uses just RGB or CMYK colour and overlooked or ignored the different colour mode called Lab Colour. Switch any enlarged image and change it to Lab color by navigating to Image > Mode > Lab Colour.
Make sure you have a channels panel open by going to Window > Channels. Then select the “Lightness” channel or click the Photoshop Tutorial : To Improve low resolution of your Image - Image 4 beside the a and b channels as shown. With “Lightness” selected, then use a Smart Sharpen filter by going to Filter > Smart Sharpen.

Test your own settings according to your own image, the settings above worked well for me. You’ll probably want to keep your “Remove” setting to “Gaussian Blur” as shown above.
You can remain in Lab Colour or convert back to RGB after this depending on your preference. Since Lab Colour, unlike a conversion between RGB and CMYK colour, RGB converts perfectly to Lab without any noticeable colour shift.
In either colour mode, select your combined channelset by pressing Ctrl + 2.It’s not perfect, but the comparison of before and after is pretty dramatic.
