In answer to the title of this article you may expect that the response is “it’s organic or natural” but that goes without saying. However, this article takes a deeper look at the classes of ingredients, the skin benefits of these ingredients and their impact on the skin. The basic aims of a good moisturiser is to maintain or restore skin barrier systems and to improve overall skin health. At a cellular level it is important that the formation of the epidermis or outer layer of skin is supported, as this is the foundation of an effective protective layer.
A well-formulated moisturiser will have the following properties:
• Mimic skin structure and function
• Slow trans epidermal water loss
• Maintain the skin’s protective barrier
• Nourish the skin by providing nutrients such as vitamins, minerals and essential fats
• Have a moisture saturating effect i.e. provide the skin with the moisture it needs
• Have a balanced pH
• Have a restorative effect i.e. work to improve superficial skin damage
In addition, it is important that the formulation looks, feels and smells nice. The aesthetics of a formulation have a large impact on its use. After all, a formulation can have amazing properties but if it sits on the bathroom shelf without being used, it is no good to anyone.
In order to achieve the above aims, a good moisturiser obviously needs to contain active ingredients but just as important are the base ingredients. In many cases, the base carriers, emollients (softening and soothing) and humectants (retains water) could also be considered active ingredients if well chosen.
Base ingredients are those that make up over 50 – 70% of the formulation. They are responsible largely for protection and hydration. If formulated well with ingredients such as fruit, seed and plant oils or gels, they will also provide some nutritional value.
The growing sophistication of natural and organic formulations highlights the key differences between these and their synthetic counterparts. Obviously the lack of potential toxic or irritating colours, fragrances and preservatives is a major difference, however, returning to the original premise of the article, “what makes a good formulation”, the key difference by proportion of formulation is actually the base ingredients. Comprising over half of the formulation, they can either actively promote skin health, or have a somewhat neutral effect.
By way of example, petroleum has an excellent and immediate barrier effect on the skin however, it sits on the surface of the skin and so stops the skin breathing and depending on where it is sourced may potentially be a source of toxic contamination. On the other hand, Shea Butter also has an excellent barrier effect but is also a source of vitamins A and E, iron and essential fatty acids. In addition it penetrates the skin readily, has an emollient effect and supports skin elasticizing. As you can imagine, a formulation containing Shea Butter is much more likely to meet the essential criteria of a good formulation.
Active ingredients are more likely to help to restore skin health and provide skin nourishment. These include antioxidants, vitamins, amino acids and minerals. They may make up between 5-10% of a formulation. These days it is common to see the same active ingredients in a good organic formulation as it is in an expensive department store brand or dermatologist cosmedic range. Ingredients such as vitamin C, alpha hydroxy acids, retinoids, hyaluronic acid and peptides are no longer the exclusive domains of dermatologists.
Depending on the formulation colours and fragrances make up less than 5%. An organic formulation is unlikely to have any added colours or fragrances but rather utilizes the natural fragrances of essential oils, which are in fact considered actives or essential oil based preservatives, which again give the formulation its fragrance.
Preservatives may also contribute up to 5% of a formulation. Depending on whether the formulation is natural or synthetically based, the preservatives will be either essential oil or plant based or a synthetic alternative such as parabens. Some organic products contain chemically modified preservatives i.e. the starting material is natural but it is modified to have a preservative-like effect. One example of this is phenoxyethanol. There are a number of ways of manufacturing this preservative however the form that is acceptable in organic formulations is based on natural starting materials.
Determining a good moisturiser from one that is…well average cannot be based on the active ingredients alone. A holistic review of the ingredients including the base formulation, colours, fragrances and preservatives will determine this and if after this you are still unsure, ask! Contact the manufacture, check the Skin Deep database or ask the retailer for a detailed explanation of ingredients so that you really know what you are putting on your face each day.

Have you noticed that organic products feel different to their synthetic counterparts? Sometimes they take a little longer to sink in or initially feel richer due to the oil component. Once applied however, you can start to notice your skin feels different, and not just after application but also over time, it feels smoother and more hydrated. There is a reason for this and it all comes down to the base ingredients used in organic skin formulations.
Conventional skin care contains synthetic ingredients such as fillers, silicon and slip agents. These make the product feel smooth as they give the product slip and are designed to settle on the top of the skin, creating a smooth barrier. It also makes your skin appear more hydrated than it actually is. In reality, the barrier created by fillers and silicone agents creates an occlusive coat, trapping ingredients below it and stopping the skin from breathing. While this may make your skin feel better in the short term, in the long term they provide little if any nourishment for the skin.
Skin “breathing” is a critical function of body detoxification. While creating a barrier to the outside world the skin also allows substances such as water, waste products and oxygen to pass through its layers. If these are then trapped below an occlusive emollient such as silicone it can lead to skin health issues such as congestion, poor skin texture and irritation. Extended exposure to sweat under an occlusive layer can further irritation. In addition, skin exposure to ingredients such as artificial colours and scents, which are already the most significant cause of skin issues, can become even more problematic if trapped under an occlusive layer.
By contrast natural base oils and butters, while giving products a smooth base feel, also allow the skin to breathe. As fatty substances they are absorbed into the skin, rather than sitting on the surface and in doing so carry important ingredients such as antioxidants through as well. In addition, they are a source of critical essential fatty acids, glycolipids and phosphlipids which support the skin cell membranes and permit nutrients and water into the cell and toxins out.
What to look for in your products are ingredients such as those listed below:
The benefits of products containing such ingredients as their basis are twofold; firstly they aren’t irritating to the skin and secondly provide essential nutrition. This is a win-win situation all round.Twitter It!
