Long Term skin trials assessing texture, and effects on types of skin.
An independent research facility conducted a single placement study with 53 female participants all over the age of 40 years old.
- 3 skin types were equally represented normal, dry and sensitive and a single daily application was studied.
- Skin types were assessed as a single cohort (combined) as well as individual cohorts.
- Short term benefits were assessed, after 6, 12 and 24 hours (trial 2) followed by the long term after 30, 60 and 90 days (trial 3).
- Test cream was a market relevant passive base formulation with a 3% Oat® COM extruded Colloidal Oatmeal inclusion using the following formulation:
- Three groups of subjects, normal, dry and sensitive skin were chosen, depending on their self-assessed skin type.
On initial application of the cream all test subjects gave positive responses for skin feel, lack of greasiness and moisturisation properties. Over 93% felt that the product left their skin feeling soft after use by selecting either ‘agree’ or ‘strongly agree’. The post absorption moisturisation responses were very positive especially for a single application. The data strongly indicates the ability of Oat® COM to improve skin feel and reduce greasiness in formulations.
Anti-aging activity over all skin types
The combined cohort trial was designed to show Oat® COM’s ability to demonstrate anti-aging activity over all skin types. The subjects were asked to assess the products moisturising, soothing, nourishing and skin feel properties.
The results (figure left) demonstrated that Oat® COM, at a low inclusion rate of 3%, displayed remarkable rapid and sustained anti-aging effects. The results were very impressive after 30 days but continued to be high over the whole 90 day period demonstrating that Oat® COM provides excellent long-term skin care benefit as an effective active over all skin types by moisturising, soothing and nourishing the skin.
Moisturisation effects on dry skin
One of the key challenges for individuals with dry skin types is the requirement for continual and consistent moisturisation. The subjects were therefore asked whether they agreed whether the product left their skin feeling moisturised, silky soft, soothed and nourished.
The results show that the subjects instantly recognised the moisturising effects and equally acknowledged that the effect was sustained across the entire ninety day period.
When subjects with dry skin conditions test moisturisers, it is expected that good short-term observations will be made, however long-term and sustained moisturising effects are rare. Dry skin conditions are often accompanied with related issues such as redness or flaking. Therefore the perceived soothing effects were also very encouraging. The results show Oat® COM as a moisturiser ideal for alleviating the symptoms of dry skin conditions.
Soothing and moisturising effect on sensitive skin
Sensitive skins are a major challenge as a definition covers a wide range of mild skin to more chronic conditions. Sensitive skin conditions tend to flare up at different times. Subjects were asked whether they agreed the product moisturised, soothed and left their skin feeling soft:
The results received were encouraging, as this is typically a very hard demographic to please and the data confirms Oat® COM as a powerful moisturising agent. As sensitive skin conditions tend to flare up at different times the consistency of results was noted, showing Oat® COM as a reliable soothing and moisturising agent over this longer period. The dry and sensitive skin cohort results show Oat®COM to be a versatile anti-aging ingredient.
The study was extended for a further 90 days to assess whether benefits could be sustained and to investigate the overall anti-aging efficacy of Oat® COM over 30, 60 and 90 days.
