chitosan is in the application of preparing in cosmetics, and described chitosan is a kind of polymer chitosan, and relative molecular weight is ～;. Aging is also part of our skin's natural cycle, and the aging process is both intrinsic and extrinsic. Cosmetic or cosmeceutical solutions containing chitosan can be developed to tackle common skin conditions such as hyperpigmentation, eczema or psoriasis, microbial imbalance, skin healing, sun damage and signs of aging, such as wrinkles, fine lines and loss of elasticity.
Also, thanks to chitosan's film-forming nature, it covers the surface of the skin in a thin and flexible film. This provides an extra layer of protection against external aggressors, while it also locks in moisture, helping the skin to remain hydrated.
Its antipruritic properties help to reduce itching, while its breathable film allows for good air permeation. Chitosan is also a powerful antioxidant , with scavenging ability against free radicals that cause oxidative stress. Oxidative stress can result in several skin problems, including skin pigmentation and premature aging, inducing changes in skin complexion, homogeneity, dryness, wrinkling, sagging, discoloration, loss of collagen and elastin fibers.
Skin photoaging, a type of skin aging damage, is caused by exposure to UV radiation, and is characterized by oxidative stress, inflammation, wrinkles, dryness, and skin laxity, among other side effects.
Chitosan can help reduce photoaging in the skin, thanks to its antioxidant and anti-inflammatory properties. Chitosan's anti-inflammatory and anti-pruritic properties also make it suitable for the treatment of acne vulgaris. Chitosan's skin healing properties help to restore irritated skin and reduce scarring, by promoting aesthetic collagen rearrangement during the natural skin healing process.
Being antimicrobial, chitosan can be widely used in oral care applications. It can reduce growth of bacteria in the mouth, enhance gum health and prevent tooth erosion.
Its antimicrobial activity can also help battle oral pathogens, plaque, gingivitis, dental caries, and other oral diseases. Oral hygiene is related to both buccal and dental health, as well as cosmetic appearance. Issues such as tooth decay, bacterial infections, gum diseases, caries and plaque can have serious health and aesthetic side effects.
It can also be used as a natural alternative to certain preservatives. Chitosan has been proposed for use in preventive and conservative dentistry, endodontics, periodontology, prosthodontics, and orthodontics. When applied to oral healthcare, chitosan can assist in preventive dentistry, to avoid gum and dental illnesses.
It can be used in toothpaste, mouthwash, chewing gum, and dental varnishes. Chitosan, having hair-fixing and antistatic properties, is a powerful ingredient for hair care. Hair can be damaged by UV exposure, heat stress from hair dryers, curling or straightening irons, perming, harsh chemicals, or chlorine.
Chitosan can help rebuild damaged hair, improve hair thickness, and provide hair with a healthy shine. Hair care products with chitosan can improve hair suppleness and softness, reduce static electricity, remove sebum and oils, improve hair hydration, fight the fungus that causes dandruff, and promote hair growth.
Chitosan can also be used as a bacteriostatic agent. Thanks to its ability to improve the flow of ingredients in hair care formulations, it can also enhance the adhesive character of specific ingredients to the hair. As chitosan's properties are related to its physio-chemical characteristics and functional properties, it is important to accurately characterize this polymer when developing a formula.
Accurate characterization is crucial, as it determines which characteristics emerge and are relevant for each specific application. Chitosan can undergo varying degrees of deacetylation to achieve the desired solution, while its molecular weight can also help formulate solutions for specific cosmetic applications.
As chitosan can be used in aqueous solutions or solid form, it can be combined with other active ingredients or bioactive products, for example for moisturizing creams, solar filters for sunscreen products, skin tones, and serums, further facilitating their effects. Chitosan's unique properties also allow its use as an emulsion stabilizer or viscosity controller when formulating cosmetics.
Chitosan's antioxidant action makes it an excellent additive that can help prevent the oxidation of other ingredients, such as vitamins or essential oils.
Chitosan, therefore, can operate as the active ingredient thanks to its own unique properties, or it can act as a delivery system. For example, in skincare, it prolongs the contact between an active agent and the epidermis, enhancing the action of active agents in a long-term controlled manner.
