From what I understand, you do own Photoshop, am I correct? If you do, I would suggest you to learn the basics to get the best results for editing your photos, maybe watch some tutorials on YouTube or something. If you don't own Photoshop, I would suggest you buy Lightroom, it's simpler than Photoshop and it is great for managing your photos.
And back to your questions, I think you should reduce the strength a bit, maybe experimenting with other simpler adjustments like contrast or brightness, I'm not really familiar with Fotor so I might not be the best person to help you use it. In general, whatever you use, I would strongly recommend looking up some tutorials on YouTube on how to improve your editing.
