For more than 90 years, Ducray’s know-how in the dermatological field has been dedicated to designing skincare products that improve everyday life. Their adage: act scientifically to soothe and take charge of dermatological disorders in the best possible way. Today the laboratories are launching a new range of innovative products: Kertyol PSO, a new generation of treatments which accompany skin prone to psoriasis. To find out more about this unique range, we spoke to Gautier Doat, doctor at the Medical Department of Ducray Dermatological Laboratories.
1 / How is the Kertyol PSO range pioneering?
At Ducray, when it comes to developing new products, our teams work closely with patients. Focus groups were created to identify their needs. For a chronic and prominent condition such as psoriasis, the issues raised often related to difficulties in the eyes of others and the constraints related to the treatments offered (texture, odor, frequency of application necessary …) Psoriasis is indeed a recurrent pathology. evolving in spurts, therefore having a strong impact on the quality of life.
It is to meet these daily needs that we have reworked the galenics of dermo-cosmetic products within the KERTYOL PSO range.This involves offering them products with a pleasant smell, which do not stain or stick to clothing, with a simplified frequency of application.
In addition to feedback from patients, we have worked with recognized experts in this field such as Professor Jean François NICOLAS, dermatologist. Its expertise has enabled us to develop products with active ingredients responding to new pathophysiological data on the disease: skin not affected by psoriasis lesions is not healthy. It has inflammatory cells that may be responsible for possible future outbreaks and pruritus all over the skin. This non-lesional skin therefore requires specific and comprehensive care for the skin of the patient suffering from psoriasis with specific active ingredients.
2 / What innovative active ingredient have you chosen to put at the heart of your formula and why?
Celastrol is obtained from the roots of Tripterygium wilfordii (TW), a plant widely used in traditional Chinese medicine for its anti-inflammatory properties. This targets both skin cells called keratinocytes (key players in inflammation) and immune cells called lymphocytes (producers of inflammation molecules). Celastrol breaks the vicious circle of inflammation responsible for psoriasis outbreaks. By the cutaneous route, contained in our specific KERTYOL PSO treatments, it acts effectively on the epidermis, both on non-lesional skin and on the skin showing psoriasis lesions.
3 / What is the Ducray routine to adopt against psoriasis?
All the products in the KERTYOL PSO range have demonstrated their excellent skin tolerance under dermatological control in patients with psoriasis. Patients who tested the product were satisfied with their cosmetic properties and perceived their effectiveness, resulting in a significant improvement in their quality of life. The objective within the entire range is also to simplify the care routines in order to meet the needs raised by the working groups of patients. All products have also been tested for use alone and in combination with drug treatments usually prescribed.
KERTYOL PSO moisturizing balm is to be applied once a day to the entire body, preferably in the morning, in order to treat all of the skin, particularly that which does not show any lesions. If a topical treatment is associated (topical corticosteroid for example), it is recommended to apply it in the evening on the lesions.
KERTYOL PSO shampoo is indicated for scalp psoriasis. It is to be used three times a week. In the meantime, if necessary, Elution shampoo can be combined. The shampoo in combination with a drug treatment is of interest in the morning, in order to rinse these topical treatments applied in the evening which can present a very sticky texture.
KERTYOL PSO topical concentrate can be applied to lesions on the body alone or in combination. In the morning to promote (thanks to its keratolytic active ingredients) the penetration of the topical medicinal product applied in the evening. It can also be left applied to the scalp overnight before being rinsed in the morning (with KERTYOL PSO shampoo or Elution) in situations of severe itching of the scalp.
And finally, the KERTYOL PSO washing gel is a specific hygiene treatment to be used on a daily basis.
