Description

"Cosmetic or dermatological composition for skin lightening"

The invention is in the field of cosmetics and relates to compositions for cosmetic or topical dermatological skin lightening which contain at least one ascorbic acid ester and at least two special plant extracts.

The invention furthermore relates to the use of the cosmetic or dermatological compositions for lightening the skin and / or for lightening pigmentations of the skin and for smoothing the skin surface and achieving a more even skin appearance.

The pigmentation of the skin takes place in the melanocytes, which are found in the lowest layer of the epidermis next to the basal cells as either isolated or frequently occurring pigment-forming cells depending on the skin type. The melanocytes form melanosomes in which melanin is formed. Through various chemical and / or physical influences, in particular by UV radiation, melanin is increasingly formed. This is transported via the keratinocytes into the corneocytes (horny layer) and leads to a brownish to brown-black skin color. Melanin is formed as the final stage of an oxidative process in which tyrosine is converted with the participation of the enzyme tyrosinase via several intermediates to the brown to brown-black eumelanins (DHICA and DHI melanin) or with the involvement of sulfur-containing compounds to the reddish phaeomelanin.

Melanin formation - and thus skin and hair color - is subject to external influences and, in addition to desired effects ("healthy tan"), can also lead to undesired phenomena, in particular UV radiation can cause the formation of freckles, but also due to genetic disposition, Wound healing or scarring or skin aging ("age spots") occur. Also, hormonal disorders may be responsible for abnormal melanocyte reactions and increased accumulation of melanin in the skin, resulting in unwanted - mostly brown - spots on the skin.

Skin aging also involves the phenomenon that dead or damaged skin cells can no longer be satisfactorily removed by conventional cosmetic skin treatments (such as peelings) and instead accumulate in the upper layers of the skin. Combined with a reduced rate of renewal of skin cells with increasing age, it may also result in an irregular appearance of the skin surface except for the formation of age spots, making skin lines and wrinkles more visible.

A variety of skin lightening compositions are known in the art. In DE 102005031482 skin whitening agents are proposed which contain ascorbic acid or its physiologically tolerated derivatives or salts and 8-hexadecene-1, 16-dicarboxylic acid, sebacic acid and / or azelaic acid.

Document DE 102012222970 relates to providing a skin lightening compositions, the possible natural product-based skin lightening agents (Exfolactive ^®) included.

However, there is still a need for well-tolerated cosmetic compositions for the treatment of heavily pigmented and / or aged skin which, in addition to a lightening effect, also cause a smoothing and care effect on the skin.

It was an object of the present invention to provide cosmetic or dermatological compositions with which several signs of skin aging can be combated in a single treatment step. In addition to the lightening of unwanted skin pigmentation and the achievement of a uniform skin tone, in particular irregularities of the skin surface should be mitigated and / or eliminated in order to achieve an overall more uniform appearance of the skin.

Another object of the invention was to find for the production of cosmetic or dermatological compositions well-tolerated, possibly based on natural substances or drug combinations.

It has surprisingly been found that the combination of ascorbic acid esters with an extract of Opuntia ficus indica and with at least one other plant extract selected from Bambusa vulgaris extract and / or Pisum sativum extract, in a cosmetic skin treatment composition to particularly good results in skin whitening, natural Exfoliation and smoothing of the skin resulted.
