Something to consider would be merging visible layers up to a new layer. Sharpen that layer, play with its opacity. Try different blend modes for the layer. In his book Skin, Lee Varis mentions making two layer copies. Sharpen one at the max of Unsharp Mask, 500%, radius 1, threshold 0. Change its blend mode to Darken. The one above, same Unsharp Mask, change its blend mode to Lighten. Then lower that layer's opacity so the highlights don't look excessively done.
With images of people, the eyes are generally what we want most sharp. If you think that there's excessive sharpening over all, mask out all but the facial features you consider most important. Excessive sharpening of women's features probably isn't a great idea. Often we want to soften their features, but have sharp, crisp eyes.
Hope I didn't ramble excessively.
