The spots can occur in just one area of the. The spots are sometimes called age spots, sun spots or liver spots. Hyperpigmentation can appear as brown, black, gray, red or pink spots or patches. Hyper means more, and pigment means color. Dilation enlarges bright regions and shrinks dark regions.
Use a darker wood stain of your existing lighter wood stain. Apply the wood stain: Now it is the turn to apply the wood stain on the previous wood stain. Wait for 5 to 10 minutes to dry the conditioner.

Hyperpigmentation is a common condition that makes some areas of the skin darker than others. When used properly, Hydroquinone is very effective in treating skin discolorations, but during the course of treatment you may notice that your skin appears darker. However, apply the wood conditioner using a soft brush or soft cloth onto the wood surface. The following code makes use of scikit-image's peak detector, applied on a distance map computed between the image and the values of pure red and blue: from skimage import io, color, img_as_floatįrom skimage.feature import corner_peaks, plot_matches
