Bottle or Jar?

You may have asked yourself why companies use a bottle or a jar for a particular skincare product. Does it really matter? The truth is that not all containers are created equal when it comes to particular formulations. Factors that affect the type of container used are:

  • Oil vs water based formula
  • Ingredients that go rancid quickly (e.g. argan, hemp oils)
  • Ingredients that degrade easily (e.g. botanical extracts, vitamins)
  • Exposure to light, heat and/or humidity
  • TSA package requirements
  • Shipping requirements

The best container for the job

When ingredients aren’t taken into consideration when choosing a bottle or jar, the result is often a less effective product. Many ingredients are expensive to source, so it makes sense for companies to choose the right container for skincare products. Here are a few quidelines:

  • For liquid formulations like soaps, gels, oils and lotions, a pump bottle works well. Opening sizes vary according to the viscosity of the liquid. It is a hygienic choice because hands don’t touch the product directly. This includes airless pumps, which introduce less air into the container, minimizing degradation. An example of this is our Vitamin C Face Creme with Niacinamide.
  • Plastic is preferable to glass if the product is used in the bath or kitchen in order to avoid having a product slip out of one’s hand and break. Check the bottom of the container to see which plastic is being used. Some are more recyclable than others. If a product is going to be heated (e.g. oil treatments), then glass is preferable, as it is inert and not likely to melt.
  • As a rule, if ingredients degrade or become rancid easily, a dark or opaque container is preferable to a clear one. Exposure to light will degrade many oils, vitamins and botanicals. As an alternative, keep the product either in the refrigerator or in a cool, dark place.
  • For thick creams, body butters and scrubs, a tube works best. That’s because it minimizes the likelihood of touching the product directly. Jars are less preferable because of what’s known as “head space”, which sometimes necessitates the use of additional preservatives to minimize contamination. Possible exceptions are products that are oil-based with low rancidity like our body balms.  Another alternative is an airless jar, a recent innovation that reduces the chance of contamination.

If you are trying a product for the first time or if you’re using it infrequently, it’s best to buy the smallest possible size. Once opened, a product’s shelf life is limited to between 3 and 12 months. If, on the other hand, you’re buying a product that you use frequently, get the largest possible size to save money.

Travel Requirements and Skincare Products

The Transportation Safety Authority (TSA) has developed strict rules regarding what to pack when traveling. As a rule, any type of liquid must be 3.4 ounces or less and sealed in a quart-size airtight bag for carry-on luggage. Anything larger must be in a checked bag. Many companies sell sample-size products that will serve this purpose. As an extra precaution, it’s a good idea to cover the area between a bottle or jar and its dispenser with duct tape to prevent its opening. It’s also safer to carry products in plastic containers than in glass ones.

Should I Re-Bottle or Re-Jar a Skincare Product?

It’s not recommended that you re-bottle or re-jar a product once you receive it. Even if you are careful to sterilize everything, you’re exposing all of the product to the elements, which introduces airborne particles and other contaminants. Exceptions might be made for household products that don’t come in regular contact with skin, like dishwashing liquid or detergents. When it comes to skincare, however, it’s best to leave it to the pros.

which cleanser right skin type

Which Cleanser Is Right For My Skin Type?

There are three basic types of cleanser – 1)soaps; 2) surfactant (or detergent) cleansers; and 3) soap-free (or oil) cleansers. It may be difficult to know which cleanser is right for your skin type, with all of the choices available. Below are the basic differences to help you choose.


Soaps can be divided into bar soaps and liquid soaps. Soaps have been around for thousands of years. Essentially, a soap is classified as a product created by combining an oil or fat with lye, or sodium hydroxide. If this process doesn’t occur, it can’t be called a soap. An example would be WEBA’s Lavender/Rosemary Bar Soap. Soaps tend to be more basic, with a pH between 10 and 12, depending upon how much sodium hydroxide is left behind and whether or not they are “superfatted.” Unlike our bar soaps, which retain glycerin and use premium butters like cocoa and shea, commercial soaps remove the glycerin for sale. It’s important to read labels; not all bar soaps are created equal. Bar soaps travel well and cost less to use than liquid soaps.

Liquid soaps are made by combining fats or oils with potash, or potassium hydroxide. This is a “hot process” reaction – the ingredients are heated for a period of time until the reaction is done, after which water is added. If less water is added, you have a gel. More water produces a thinner formula. These also tend to be more basic. A major difference between liquid and bar soaps is that with liquid soaps, a preservative must be added due to the high water content. Again, read labels to see what preservatives or other ingredients are used.

Soaps, because they clean so well, are generally fine for people with combination or oily skin, although soaps can have ingredients added to them which make them more moisturizing for all skin types. Many also find liquid soaps convenient and more hygienic than bar soaps. It’s really a matter of personal preference.

Surfactant (detergent) cleansers

Surfactant cleansers include detergents (e.g. dish detergent, laundry detergent) and are generally synthetics (made in a lab). Many of the “Beauty Bars” are, in fact, a combination of surfactants formed into a bar under high pressure. Some surfactants like Sodium Lauryl Sulphate have fallen into disrepute lately, but there are other naturally-derived surfactants like Coco Betaine, which cleans more gently compared with soaps. These tend to be better for persons with problem skin (acne, ezcema, etc.). This class of cleansers is popular in shampoos, as well, because many have conditioning properties.

Soap-free (oil) cleansers

Soap-free cleansers can include oil-free cream and oil cleansers. They are good for dry, combination and oily skin and are good at removing makeup. Oil-free cleansers consist entirely of surfactants, some synthetic and some naturally-derived, with perhaps a wax and conditioning agents. Reading the labels on these products can be confusing because of the chemical names. What is polyethylene? (A plastic resin). What is Methyl Lactate? (A solvent.) It can also be difficult to determine whether ingredients come from plants or animals. Most have water as their first ingredients, necessitating a preservative. And just because these products are soap-free doesn’t mean that you can’t react to one or more ingredients. Companies are required to provide common names on their labels; you can search for information about an ingredient if you’re not sure what it is.

Oil cleansers are also soap-free, but usually contain a combination of oils along with other beneficial ingredients. Again, check the label if you want to be sure that you’re not sensitive to an ingredient like nuts or certain essential oils. One example of an oil cleanser is our Whole Earth Body Actives Gentle Facial Cleansing Oil and Makeup Remover. Ours is free of essential oils, perfumes and dyes. These also tend to be used exclusively for the face, unlike other cleansers. They tend to be less irritating to the eyes.

Our recommendation? It’s probably best to use a variety of cleansers, depending on your family’s skincare needs and their particular use. For travel, bar soaps are best. When skin is dry, try a cream cleanser. To remove makeup and excess oils, try an oil cleanser. Regardless of which you choose, always check labels so you know what is going on your skin, and to avoid irritation.
