After Bite is an American brand of outdoor mosquito bite anti-itch products, which has been the sales champion in the field of outdoor anti-itch products for many consecutive years, and the products have also been recommended by authoritative review websites such as Bestreviews.

After Bite's anti-itch products are known for their mildness, mainly for infants and young children, a total of 5 models, of which Advanced Formula (dark green) and Kids (purple) are mainly composed of 5% sodium bicarbonate (NaHCO3), claiming that it can neutralize the acid secreted by mosquitoes through alkaline substances (sodium bicarbonate), and then eliminate the itching pain after biting.

In fact, the anticoagulant in mosquito saliva is an exogenous substance, once it enters the human body, the immune system will immediately respond and release histamine, an appropriate amount of histamine can protect the human body, but everything is too much, because histamine is the main itching medium in the human body, once it is excessive, it will stimulate the nerve endings in the skin and bring itching.

Once histamine is produced, weak alkaline substances cannot remove it, so the so-called neutralizing products such as Advanced Formula (dark green) and Kids (purple) on the market cannot reduce swelling and itching from the root.

In contrast, After Bite's other three products: Xtra, Outdoor, and Plus really have anti-itching effects, and the ingredients are all added with 2% diphenhydramine hydrochloride (Diphenhydramine hydrochloride), which improves the efficiency of itching and swelling, and also has a certain effect on the pain caused by midge bites, all of which are 0.7oz (20g) gel-type products, priced at about 50 yuan, and the cost performance is also okay.

However, like many brands, After Bite also has no official purchase channel in China, and can only be purchased through purchasing agents or overseas shopping, which is also more troublesome.
