A solution, applied to the skin, that causes the top layers to peel off. These can be made of fruit acids and can be very strong or mild, depending on the individual requirement.
Also known as Beta hydroxy acid this is a mild exfoliant that helps peel off dead layers of the skin. Beware if you have an aspirin allergy as it may cause a serious swelling reaction.
Permanent cosmetic implants could cause allergic reactions such as arthritis, according to a report published in the Archives of Dermatology journal.
Doctors have reported that some patients developed problems over a year after the fillers or implants were placed.
The report said that the safety of polyalkylimide implant gels is questionable.
Dr Jaume Alljotas-Reig of the Vall d’Hebron University Hospital and Autonomous University of Barcelona said that both doctors and patients needed to be aware of delayed reactions.
The team examined 25 patients who had adverse reactions a year or more after having filler implants.
Dundee: Cooking methods may increase the acidity of foods, therby increasing dental erosion, researchers at the University of Dundee have found. The research was prompted by the premise that vegetarians may be more at risk from dental decay because the vegetables and fruits they eat are higher in acids than foods in a usual diet.
They looked at the classic French dish Ratatouille, a vegetable stew which has a high tomato, garlic and olive oil content, and discovered that roasting the vegetables first made it almost as acidic as some carbonated drinks.
The research team was led by Dr Graham Chadwick in the School of Dentistry, which found that although the dish was acidic, roasting it made it more so.
Dental erosion is caused by the direct contact of acid with the teeth. The acid destroys tooth tissues and can result in severe destruction, leading to the need for expensive and time-consuming dental treatment.
The Dundee team also investigated whether the cooking method had an impact on the acidities of individual vegetables and fruits. They found the cooking method had no impact on the acidity of tomatoes or onions, but roasting resulted in more acidic aubergines, green peppers and courgettes. Red peppers were more acidic when stewed.
The research is published in the current edition of the European Journal of Prosthodontics and Restorative Dentistry. It is one in a series of research projects being carried out at the University looking into the causes of dental erosion.
