Important: Quark (or yoghurt) should never be applied directly to open wounds! This also applies to severe sunburn with blistering.
(How well) does quark help?
The effect of quark/yoghurt as a home remedy for sunburn is not yet in meaningful studies have been examined. Basically, cooling is recommended for sunburn, so some may find a quark wrap beneficial. A quark wrap will probably not do any harm. However, whether the quark has any other special use has not been sufficiently researched. It is also unclear how exactly the quark is supposed to work – if it works.
Aloe vera as a home remedy against sunburn
Preparations with aloe vera are said to help with numerous complaints, including sunburn and other burns. Applied as a gel, the plant, which belongs to the grass tree family, is said to accelerate the healing process.
The ingredients of the aloe vera preparations come from the water storage tissue of the leaves. Some also swear by dripping the plant juice directly onto the injured skin.
(How well) does aloe vera help?
Studies on aloe vera abound. However, many are based on insufficient scientific standards, so that no general statement on effectiveness can be derived from them. The extent to which aloe vera actually promotes wound healing has not yet been conclusively proven by meaningful studies. However, many find the cooling effect of the aloe vera gel to be beneficial.
Other remedies for Sunburn: tea, vinegar, ice cubes
In addition to quark, yoghurt and aloe vera, there are numerous other home remedies for sunburn and their benefits is also not sufficiently documented. These include, for example, poultices with apple cider vinegar, boiled and cooled tea bags or lemon juice.
Sometimes, however, supposed home remedies can do more harm than good. Lemon juice or too much concentrated apple cider vinegar on sunburn can lead to skin irritation in sensitive people.
Be careful with ice cubes or ice-cold cooling pads: These should not placed directly on the skin – otherwise there is a risk of frostbite with further skin damage. A protective cloth should always be placed between the cooling source and the skin.
Sunburn: When home remedies are not enough
In the case of sunburn, the first thing to do is get out out of the sun! Those affected should then cool the skin area well, for example with damp-cold compresses or gels, creams and lotions from the pharmacy. If necessary, preparations containing cortisone can also be helpful for application.
Sometimes these measures and/or home remedies are not sufficient. Medical advice is needed when a large area of skin is affected. The same is true if the sunburn is very severe — for example, if blisters form. You should also see a doctor if you have symptoms such as fever, chills, nausea or headaches.
