TOPICAL SKIN CARE COMPOSITIONSFILED OF THE INVENTION
[0001] The present invention relates to topical compositions and methods for skincare treatment employing the topical compositions disclosed herein. More specifically, the topical compositions and methods for skincare disclosed herein are cosmetic formulations that may be applied to various areas of human skin, including but not limited to face and neck areas to treat signs of aging such as wrinkles, fine lines and sagging skin.BACKGROUND
[0002] Normal healthy skin has a smooth epidermal layer that acts as a strong barrier to water and environmental damage. Natural firming and hydrating elements such as collagen (which provides skin firmness), elastin (which supplies skin elasticity and rebound) and glycosaminoglycans or GAGs (which keep the skin hydrated) are abundant in normal healthy skin. Aging can have a negative effect on the health, function and appearance of skin.
[0003] Aging caused by the natural aging process is sometimes referred to as intrinsic aging. Intrinsic aging is a continuous process that normally begins in the mid-twenties. Aging slows the natural production of collagen, elastin, and GAGs within the skin, which results in unwanted changes in skin such as dryness, itchiness, redness, shadows or dark areas, sagging, thinning, or more noticeable fine lines and wrinkles. Aging also slows the natural production of adenosine triphosphate (ATP), a nucleotide known to drive and participate in intracellular processes including repairs. Dermal levels of ATP decline with age and create an energy deficiency, thereby affecting dermal function and skin appearance.
[0004] Aging caused by environmental factors such as sun exposure, chemicals, microorganisms, food or environmental pollutants can accelerate the aging process. Aging due to environmental factors is sometimes referred to as extrinsic aging, which can trigger a variety of enzymatic and non-enzymatic modifications in skin. One such non-enzymatic process is the reaction of proteins with reducing sugars (glycation or Maillard reaction). Glycation alters the structure and functional properties of proteins, including collagen, elastin, and GAGs, and adversely affects cellular metabolism. The accumulation of glycation products is observed in skin during aging.
[0005] Aging generally causes a decrease in a subject’s extracellular matrix (“ECM”) and its major component hyaluronic acid (“HA”). HA stabilizes the intracellular structures by forming a viscoelastic network in which collagen and elastin fibers are embedded. HA provides a cushion effect to the skin structures including the epidermis. The loss of HA and consequently the viscoelastic buffering system contributes to tearing, resulting in skin disruptions and skin dehydration leading to visible wrinkles on stratum corneum.
[0006] Destruction and / or loss of dermal collagen fiber also contributes to skin wrinkling and increased appearance of muscular attachments.
[0007] The biological signs of aging are apparent in both the epidermis layer and dermis layer of the skin and include a decrease of epidermal thickness (that correlates with the reduced keratinocyte proliferation), a reduction and disorganization of major key components, such as HA, collagens and other elastic fibers (proteoglycans and glycosaminoglycans), an increase in matrix metalloproteinases production and a flattening of the dermal-epidermal junction (“DEJ”).
[0008] With age, skin homeostasis is also disrupted, metabolic activities are slowed, and endogenous production and accumulation of reactive oxygen species (ROS) leading to oxidative cellular stress and secretion of inflammatory mediators may occur.
[0009] The prior art is replete with various topical compositions for treating the signs of aging skin. Some such compositions are described in U.S. Patent Nos. 11,224,566 and 11,696,888 which are incorporated herein by reference. Examples of commercially available topical products that have been or are marketed for treating the effects of skin aging include SKINMEDICA’s HA5® Rejuvenating Hydrator, ALASTIN’s HA (Hyaluronic acid) IMMERSE SERUM™, ALGENIST’s GENIUS LIQUID COLLAGEN®, ELEMIS’ PROCOLLAGEN MARINE CREAM, PCA SKIN’s COLLAGEN HYDRATOR CREAM, SKINCEUTI CALS’ Hyaluronic Acid Intensifier, and SKINCEUTICALS’ Hydrating B5 Gel.
[0010] Although numerous topical anti-aging compositions are described in the art, there remains a need to develop an improved topical anti-aging, skin care composition.SUMMARY OF THE INVENTION

In certain aspects of this embodiment, the topical composition will further comprise at least about 60 wt% or more of water.
[0014] The topical composition may be applied to various skin areas of a human subject, particularly areas of the face, neck and decolletage area at least once or more times a day, preferably two, three or four times a day.
[0015] In certain embodiments the topical compositions may also be applied to various skin areas before, during or after an ancillary therapy, including but not limited to laser treatment, chemical peels, intense pulsed light, dermabrasion or cryotherapy.

[0023] Before the present invention is further described, it is to be understood that this invention is not limited to the particular embodiments described. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.
[0024] It should be noted that as used herein, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.
[0025] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range, is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges, and are also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the invention.
