[0033] The effective components of willow for post-sun repair mainly include the following categories:

[0034] 1. Tannins

[0035] Content and characteristics: Willow is rich in tannins, which have a relatively high content in willow and are one of the important chemical components. Tannins have astringent effect, which can help shrink the dilated pores caused by sun exposure and reduce the evaporation of water on the skin surface, thereby playing a moisturizing role.

[0036] Effect: Tannins can also inhibit bacterial growth, prevent post-sun skin infection, and promote skin repair and regeneration.

[0037] 2. Flavonoids

[0038] Content and characteristics: There are many flavonoids in the willow, which are natural antioxidants.

[0039] Effect: Flavonoids can remove free radicals, reduce the damage of ultraviolet rays to the skin, prevent post-sun skin aging, and also have certain anti-inflammatory effect, which can relieve the redness and discomfort of post-sun skin.

[0040] 3. Willow polysaccharide

[0041] Content and characteristics: Willow polysaccharide is another important component in willow, which has many biological activities.

[0042] Effect: Polysaccharide ingredients can enhance the immunity of the skin, promote the metabolism and repair of skin cells, and help the recovery of post-sun skin.

[0043] 4. Other ingredients

[0044] Organic acids, steroids and anthraquinones: Although these components have a small amount in willow, they also have certain biological activity and can assist in the repair of post-sun skin.

[0045] Application suggestions

[0046] Post-sun repair: Willow extract or cosmetics containing willow ingredients can be applied to the skin after sun exposure, gently massage for a few moments to promote absorption, which can effectively relieve the discomfort of post-sun skin and promote skin repair and regeneration.

[0047] Precautions: Although willow has many skin care effects, everyone's skin condition and needs are different, so when using cosmetics containing willow ingredients, it is recommended to do a skin test on the back of the hand or behind the ear to ensure that it does not cause an allergic reaction.

[0048] Therefore, the effective components in willow, such as tannins, flavonoids, polysaccharides, etc., play an important role in post-sun repair. They can shrink pores, moisturize, antioxidant, anti-inflammatory, enhance immunity, etc., which can help relieve the discomfort of post-sun skin and promote skin recovery and regeneration.

[0049] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
