Background and the Prior Art
Ultraviolet radiation (UVR), a major culprit in skin damage (Massimiliano Gentile et al. 2003, Nucleic Acids Research, Vol. 31(16)4779- 4790), is divided to three regions based on ensuing biological affects, UVC (200- 280nm), UVB (280-315nm) and UVA (315-400nm). UVC though being most toxic is mainly reflected by stratospheric ozone and hence does not reach the Earth’s surface (Kumar et al. 2009, Indian J. of Experimental Biology, 47: 906-910). Ten percent of penetrating UVR is UVB which plays a predominant role in photo-carcinogenesis by DNA damage (M. Ichihashi et al. 2003, Toxicology, 189: 21-39). UVB also causes photo-ageing by directly upregulating the matrix metalloproteinases (MMPs) that degrade proteins in extracellular matrix. UVB also leads to ‘delayed tanning’ (Wonseon Choi et al. 2010, Journal of Investigative dermatology, 130: 1685-1696). In contrast, UVA is estimated to contribute only 10-20% to the carcinogenicity of sunlight (Desiree Wiegleb Edstrom et al. 2001, Photodermatology, Photoimmunology and Photomedicine, 17(2):66-70), but is majorly involved in causing photo-ageing owing to its greater penetration to the skin dermis. UVA generates reactive oxygen species (ROS) and causes immediate pigment darkening (IPD) as well as persistent pigment darkening (PPD) of skin (Wonseon Choi et al. 2010, Journal of Investigative dermatology, 130: 1685-1696).
To combat the harmful effects of UV radiation 23 UVB and UVA sunscreens approved by EU are available in the market. Aside from avoiding sunburn, modern-day sunscreen also has the potential to prevent skin cancer and slow photo-ageing (UliOsterwalder. 2011, Expert Rev. Dermatol. 6(5), 479–491). The earliest sunscreens had offered protection only against UVB radiation. Further research established deleterious effects of even UVA radiation on skin. This led to the advent of UVA sunscreens thereby providing broad-spectrum UVB and UVA protection.

Effect of UV on photo damage of skin is obvious, for which various sunscreens are available to protect the skin. However, the effect of visible light on photo damage of skin is currently being explored in detail. Visible light penetrates deeper into the skin reaching even the hypodermis. It causes generation of Reactive oxygen species (ROS) by interacting with the endogenous photosensitizers, induces inflammatory cytokines (IL-1, IL-6, IL-8, GM-CSF), and induces expression of extracellular matrix degrading enzymes (MMP-1 and MMP-9). All these precipitate into skin photo-aging. Exposure to visible light also leads to skin darkening (Dupont et al. 2013, Intl. J. of Cosmetic Science. 1-9). Amongst the visible light green light is prominent in triggering the deleterious effects on skin. Green light is also proven to play a role in skin melanoma (Richard B. Setlow. 1999, JID Symposium proceedings. 4(1)) and to cause skin and immune system damage (Bohm et al. 1995, Photochemistry and Photobiology. 62(6), pp. 980-983).
US 5554374 discloses the process of preparation of a composition for skin comprising excipients, a drug carrier encapsulating beta-carotene and a blend of UV-A and UV-B sun filters characterized in that the drug carrier consisting of nanospheres represents 3 to 6% by weight of the preparation; the proportion of UV-B filters is greater than that of the UV-A filters; and the UV-B filters have a cinnamic structure. The composition finds application in the treatment of melanic skin stains.

US 2011/0033400discloses cosmetic formulation comprising (a) particulates having an absorption in the range of 400 to 800 nm; and (b) UV filters selected from (b1) particulate organic UV-filters; and (b2) soluble organic UV filters. The prior art teaches a lot of components including acid red and beta-carotene.

US 8,465,729 provides a photo-protective composition that has a synergistic combination of at least one sunscreen agent and at least one carotenoid, which results in a composition with an increased SPF compared to a composition without the synergistic combination. Preferably, the composition also has at least one of the following additional components: emulsifier, emollient, skin-feel additive, moisturizing agent, film former/waterproofing agent, pH adjuster/chelating agent, preservative, or any combinations thereof.

Even though the deleterious effects of green light on human skin is being looked into in great detail by the scientific community there are no sunscreen- like molecules identified which can absorb green light and thereby protect the skin from getting damaged. Hence there is a need for a composition which would protect the human skin against the visible light, more particularly against the green light. The current invention tries to address the aforesaid problem of attenuating green light by identifying a combination of two molecules namely ß-carotene and Acid red 52 (C.I. No: 45100) dye which absorbs visible light from 500 to 570nm.
