Here, I will give a quick review of a few of the most popular products. There are also several other sites I recommend that cover a wide variety of snoring products. Please note that these reviews are my personal opinion and not necessarily those of my physicians.
The most popular and most expensive snoring mask. It is made of a mix of olive and almond oils, and contains a lot of sodium and vitamin E, but not much other stuff. This product is so popular that I have a whole separate page for it! The mask has four main features: It is very expensive. It is a non-masking mask. It's made from an extremely high concentration of the following: Water-based moisturizer.
Olive and almond oils.
Grapefruit seed oil. It contains: water-based moisturizer. (This is very important. For a good moisturizer, the ingredients should have more than a 5% water-based moisturizer.) Olive and almond oil. The following ingredients also have water-based moisturizer: cocoa butter (and some other vegetable and animal-based ingredients), polybutylene glycol, lanolin, emulsifying fats (palm, olive, sesame, soybean, etc.), vitamins (including E, C, and D, but also iron and vitamin B, as well as vitamins A and D), and minerals (and even iron). The other oils listed here should be very important, and the products should contain at least some of these ingredients.
