Dermatest clinical trials

dermatest is an independent institute, recognised at an international level – founded in 1978 (like La Vialla!) – that carries out dermatological tests on a wide range of products. Its seal guarantees that the product has been tested according to precise, strict criteria and certifies perfect skin tolerability. The 5-star seal is only awarded to products that are clinically tested.

To verify their tolerability and effectiveness, each product was tested for 4 weeks, on 20 volunteers, in clinical cosmetic application studies carried out at the dermatest institute.
The formulations were tested according to dermatological and clinical criteria, without the skin showing sensitivity, undesired or even pathological reactions.
All the products tested, including the new ones, received the highest distinction – Excellent 5-star.

From the dermatological and clinical trials, it was seen that the Intensive Serum improves skin hydration by 54% and reduces wrinkles and imperfections by 24%; the Face Cream improves skin hydration by 25% and reduces wrinkles and imperfections by 15%; the Hand Cream improves skin hydration by 32% and the Body Cream by 53%. What’s more, 90% of the volunteers confirmed that their skin was smoother, softer, generally improved in quality, after just 4 weeks.

For the Nourishing Cream and Olive Salve, developed for the delicate skin of babies and children (and of many adults), a tolerability test was carried out on children from 0 to 3 years of age, as well as a skin-protection test (Noxae with irritation) on adults (dry and very dry skin) which highlighted the protective effect. These two products are also indicated as cosmetic aids for the treatment of neurodermatitis.

For the Intensive Purifying Gel Face Wash for blemished and acne-prone skin, Dermatest carried out a study on 20 people with spots and impure skin. The results showed a marked positive effect on skin prone to blemishes and acne. Evaluation was carried out straight after the first application (immediate effect) and after 4 weeks (long-term effect).
Shortly after the first application, a marked reduction was observed in bacterial germs of the skin, which may be responsible for inflammation and spots, and skin lipids were reduced by 78.06%. After 4 weeks, there was a marked reduction in bacterial germs and skin lipids. Comedones1 (or blackheads) were reduced by 21.45%, papules2 by 21.16% and pustoles3 by 17.86%.

1 Comedones develop when pores become clogged. They may be open or closed: “open” ones have a small dark dot of melanin in the centre and are known as blackheads.
2 Papules are small bumps that can be felt under the skin surface; they can be as large as a pea.
3 Pustules have small cavities on the surface that fill with pus (both papules and pustules are commonly known as “spots”).

The clinical trials and dermatological tests carried out on the new products (Shampoo, Hair Tonic and SOS Spray) have shown, as always, the utmost skin compatibility, excluding unwanted, sensitising or pathological reactions.
Further tests, carried out for the SOS Spray, have certified an improvement of 24.93% in skin hydration and a decrease of 5% in the skin’s temperature (refreshing/soothing effect, excellent for relieving, for example, the itch of mosquito bites) immediately after application. What’s more, the majority of those participating in the tests, in a general evaluation survey, evaluated the SOS Spray as extremely effective against the formation of perspiration and unpleasant odours.

For the new products dedicated to in-depth care of the scalp and hair, a series of specific tests were carried out, with the participation of 20 volunteers for a period of 3 months, during which they used the Hair Tonic (1-2 times a day) and the Shampoo (2-3 times a week).
The results – obtained by measuring objective parameters used in the field of cosmetics – revealed the data summarised below.

Results of the dermatest clinical trials regarding the Hair Tonic and Shampoo:

- Improvement of general hair condition: +26.17%
- Improvement of scalp condition: +26.74%
- Improvement of terminal hair density: +14.9%
- Improvement of hair thickness: +8.3%
- Improvement of shine: +20.7%
- Reduction of dandruff
