Skin Lightening Treatments. Skin lightening products -- also known as bleaching creams, whiteners, skin brighteners, or fade -- work by reducing a pigment called melanin in the skin. Most people who use lighteners do so to treat skin problems such as freckles, age spots, acne scars, or discoloration related to hormones.he active ingredient in some skin lighteners is mercury, so bleaching can lead to mercury poisoning. Mercury is a toxic agent that can cause serious psychiatric, neurological, and kidney problems.
Spider mites - outdoors. Spider mites are very common pests of outdoor plants. The mites suck juices from the plants, causing the plants to look dull and unhealthy. Mites also cause plants to lose vigor so that they may be unable to overcome a severe infestation, resulting in the plant's death. In Missouri, the most common outdoor spider mite is the two-spotted spider mite.
Tropical house plants need moisture, light and air to thrive. If any one of these factors gets out of balance, trouble occurs. Too much moisture can cause leaf spot and tip burn. Too much direct sunlight can blister the leaves. Too little air can cause the leaves to remain too moist, causing fungus to grow. Indoor plants generally prefer moist conditions with very little direct sunlight. So do most fungi. Air movement around and through your palm will help the plant's leaves dry off while moving the oxygen produced by the specimen. The dry leaf surface will not harbor fungus.
