A large number of cosmetic formulations have been developed based on herbs. Indian women have been using herbs such as sandalwood, aloe for skincare protection, since ages. In India, the rich cultural heritage is behind the materials used in cosmetics from the earliest period of medical and cosmetic art.
Continuous application of synthetic compounds on the skin causes many adverse effects such as skin irritation, allergy, discoloration, rashes along with skin cancer. The aim of this review article is to explore herbs for different skincare needs.
Materials and Methods:
A literature search was done on various herbs used for skin nourishment, cleansing, sun-screens, bleach, anti-ageing, moisturization and other skin requirements.
There are various herbs present in nature. They improve and clarify skin gently in an utmost manner.
These herbs are full of phytoconstituents, having natural goodness to fulfill the different demands of skin.
Ayurveda makes use of many herbs to make cosmetics for beautification and protection from external effects. The natural phytoconstituents not causes any side effects on the human body; but provide nutrients and other useful minerals to the body . Herbal cosmetics or products are made from various cosmetic ingredients to form the base in which one or more herbal ingredients are incorporated for defined cosmetic benefits . The health, habits, job routine, climatic conditions and maintenance are mainly responsible for the skin and hair beauty . Excessive exposure to heat, the causes skin to dehydrate during summer and causes wrinkles, blemishes, pigmentation and sunburns. Extremes of winter causes damages to the skin and hairs in the form of cracks, cuts, infections, hair fall and dandruff . The diseases of skin are common among all age groups and can be due to exposure towards microbes, chemical agents, biological toxins, and also due to malnutrition . large number of herbs are available commercially as cosmetics for skincare, hair care and anti-oxidant effects. These herbal formulations produce cleansing and beautifying effects and improves overall appearance when rubbed, poured, sprayed externally or applied to body parts [6-10]. Cosmetics from natural sources are considered better and safer . Plants are the natural sources of cosmetic formulations. They can be used to design some useful inorganic materials that are called green synthesis.  They are made from original ingredients in plants, leaves, roots, fruits and flowers which have properties for health and beauty . Major chemical compounds in plants are alkaloids, flavonoids, terpenoids, steroids, tannins and saponins which can be assessed by phytochemical screening. Herbs serve as important cosmeceuticals as they do not carry any adverse effects . They can be categorized as shown in Fig. (1).

Literature was studied in order to obtain the information about herbs that play an important role in skin care and its various complications. The search was done on Google scholar, MEDSCAPE, BMC, Science Direct, MEDLINE database, SCOPEMED and other relevant databases, using keywords like herbs, skin, phytoconstituents, care etc. The information was also extracted from various Ayurvedic treatises, textbooks of Ayurveda and books of Pharmacognosy available in the Library of Pranveer Singh Institute of Technology, Kanpur, and NBRI Lucknow. Available dissertations/thesis and various research articles were also investigated.
2.1. Herbs With Anti –Acne Effects
Acne develops when pores become clogged or infected with bacteria. Acne is the most common skin condition, affecting around 80 percent of people in their lifetime .
2.1.1. Green Tea
It contains high concentrations of polyphenol antioxidants called catechins. Most people with acne produces lots of sebum or natural body oil in their pores and lack enough antioxidants. Sebum secretion is associated with hormonal activity in the human body  and excess sebum production causes skin disorders, such as acne vulgaris. Antioxidants help the body to break down chemicals and waste products that can damage healthy cells. Green tea clears out some of the debris and waste that causes open acne sores. It contains compounds that may help to reduce sebum production and inflammation. Components of green tea beverage measured as weight percentage of extract solids include 30%–42% catechins, 5%–10% flavonols, and 2%–4% other flavonoids . Catechins are divided into catechins, epicatechins, epicatechin gallates, epigallocatechin, and epigallocatechin-3-gallate, which are mainly responsible for the anti-oxidant property of green tea. Green tea is available in the form of serums and hydrating lotions [18, 19].
Manjistha is reputed as an efficient blood purifier and hence is extensively used against blood, skin and urinary diseases. Manjistha is used externally on major burns, mixed with honey and on freckles and blemishes. It is a potent drug for severe skin diseases . Methanolic extract of Rubia cordifolia inhibits proliferation of acne. It is moderately effective against TNF alpha and shows low activity against IL-8. It is regarded as an astringent and treats external inflammations like ulcers and skin diseases. The anthraquinone rich fraction of a plant in a gel formulation shows anti-acne activity against Propionibacterium acne, Staphylococcus epidermidis, and Malassezia furfur, as compared with the standard Clindamycin gel. Manjishtha is available in the form of gel and ointments [21-25].
2.2. Herbs With Anti-Inflammatory Effects
Inflammation is a defense response of our body to hazardous stimuli such as allergens or injury to the tissues. Uncontrolled inflammatory response is the main cause of a vast continuum of problems such as allergies.
Aloe vera inhibits the cyclooxygenase pathway and reduces prostaglandin E2 production from arachidonic acid. It is used in the form of soothing gels [26-28].
For more than 4000 years, Santulum album L., belonging to the family Santalaceae has been used mainly in religious rituals as fragrance and is also used as a flavouring agent in Ayurvedic medicine to manage inflammatory reactions initiating various skin disorders [29, 30]. In addition, it has been used as an astringent. It is used in the form of face packs, masks, etc. [31-34].
2.3. Herbs With Anti-Oxidant Effects
Antioxidant concept refers to mechanisms for staving off “free-radical” reactions. Such “radicals” have definitively been shown to affect all biochemical components such as DNA/RNA, carbohydrates, unsaturated lipids, proteins and micronutrients such as carotenoids, vitamins A, B6, B12, and folate [35, 36].
Nature has gifted Emblica officinalis with defensive antioxidant mechanisms,-superoxide dismutase, catalase, glutathione, GSH peroxidases, reductase, Vitamin E, Vitamin C, etc., along with several dietary components. Diverse potential applications of antioxidant or free radical mani- pulations in the prevention or control of disease have been revealed by several researches. The fruit extract produces positive responses in total phenol, total flavonoids and total tannin assays, that is used in the form of a scrub [37, 38].
Rosmarinus officinalis L. is a rich source of phenolic compounds and its properties are derived from its extracts and essential oils. Extracts of rosemary also contain several antioxidant and volatile components such as phenolic acids, flavonoids, and diterpenoids. There are seven main flavonoids in rosemary leaves, flowers, roots and stem. Rosemary oil hydrates the skin, which helps to control oil production. It also provides an antibacterial surface to the skin, keeping acne at bay. The presence of 7-O-glucoside, hispidulin, diosmin, hesperidin, 3′-o-β-D-glucuronide, genkwanin and isoscu- tellarein 7-O-glucoside has been studied. They play an important role in anti-ageing [39-41].
2.4. Herbs With Anti-Wrinkle Effects
The botanical ingredients present in herbal cosmetics impact biological functions of the skin and provide the nutrients required for a healthy skin. The imperative efforts associated with medicinal plants with scientifically validated mechanism leads to the emergence of novel cosmeceuticals for the prevention of sagging [42, 43].
The vitamins A, C, and E, β-carotene and selenium contents of apricot showed wrinkle prevention qualities. The total oil content of its kernels ranged from 40.23 to 53.19%. Oleic acid contributed 70.83%, followed by linoleic acid 21.96%, palmitic acid 4.92% and stearic acid 1.21% as fatty acids. It was reported in another study that the seed oil is a rich source of P, Ca, Mg, Fe and Cu, and contained 73.58%. oleic acid. It is used in the form of sheet or scrub [44, 45].
2.5. Herbs with Depigmentation Effects
Depigmentation is the lightening of the skin, or loss of pigment. Depigmentation of the skin is due to a number of local and systemic conditions. Pigment loss can be partial or complete. It can be temporary such as in tinea versicolor or permanent such as in albinism [46, 47].
Some constituents of leaf of Carica papaya are myrosin, alkaloids, rutin, resin, tannins, carpaine, dehydrocarpaine and pseudocarpaine enzymes, ascorbic acid and saponins. Aliphatic and aromatic hydrocarbons contribute to aroma. On the other hand, the following carotenoids along with vitamin C increases on ripening as lycopene, β-criptoxanthin, β-carotene [44-46]. Carotenoids helps in depigmentation of the skin, generally used in the form of face wash, and also help to remove tan.
Its extract is rich in vitamins, especially vitamin C and A, which have some cosmetic benefits for the skin, hence it is used to make sheet masks and gel. Cucumber has an excellent potential for cooling, healing an irritated skin, whether caused by sun or due to cutaneous eruption. Cucumber extract is often used for skin problems, wrinkles, sunburn and as an antioxidant [47-50]. Cucumber extract is a superfood for skin. The juice is composed largely of proteins, lipids, Vitamin C and a variety of minerals and possesses moisturizing and emollient properties. It also has astringent effects and can soothe and relieve puffy skin.
Astringents are chemical compounds that help to shrink pores and constrict body tissues. Astringents are used for treating skin irritations, such as acne. They are also used to relieve allergies, insect bites and fungal infections. Astringents work well on oily skin.
2.6. Witch Hazel (Hammamelis Virginiana)
Witch hazel is an excellent herb with high concentration of tannins, and is a great herbal astringent. The leaves and bark are highly beneficial. Witch hazel is used to protect the skin and the herb can be used to prevent future blemishes as well.
2.7. White Oak (Quercus Alba)
As another potent astringent, the white oak is a giant tree native to North America. The powerful astringent properties lie in the bark. It is also a high source of tannins and iron. The white oak is used to create skincare products as well. White oak has also been known to treat infections and protect against harmful bacteria [51, 52].
2.8. Herbs Used for Anti-aging Treatment
It is obtained from the plant Daucus carota belonging to the family Apiaceae. It is a valuable herb because of its richness in Vitamin A. Carrot seed oil is used as an anti-aging, revitalizing and rejuvenating agent. It gets its bright orange colour from β-carotene and lesser amounts of α-carotene and γ-carotene. α and β-carotenes are partly metabolized into Vitamin A. It is available in the form of packs and lotions.
It comes from the ginkgo tree, Ginkgo biloba, belonging to the family Ginkgoaceae. It is best known as a circulatory tonic, in particular for strengthening the tiny little capillaries in present the organs, especially in the brain. The capillaries become more flexible with ageing, therefore more oxygen is delivered to the organs as well as skin. Ginkgo is used in the form of micro-foliant [53-55].
2.9. Herbs With Sunscreen Effects
Sunscreen products are very popular nowadays. Earlier, people would get beautiful sun tan easily and, without the risk of sun burns. Nowadays, it is necessary for to use sunscreen products against ultraviolet radiations.
2.9.1. Cucurbita pepo (Pumpkin)
With a lipid profile from the seed containing high levels of linoleic acid (43 – 53%), it contains two classes of antioxidant compounds: Tocopherols and phenolics, which account for 59% of the antioxidant effects. The skin's natural sun blockers are proteins with peptide bonds, absorbing lipids and nucleotides. It is used in the form of hydration mask and serum. The high concentration of plant peptides protects the peptide bonds of the skin proteins. Cucurbita pepo seed oil deserves greater recognition, as in the form of masks and serum. With a lipid profile containing high levels of linoleic acid (43 – 53%), it contains two classes of antioxidant compounds: Tocopherols and phenolics, which account for 59% of the antioxidant effects .
The extract is made from the fresh green shells of English walnut, Juglans regia. The aqueous extract acts as a self-tanning sunscreen agent. Its most important component is juglone, a naphthol closely related to lawsone. Juglone is known to react with the keratin proteins present in the skin to form sclerojuglonic compounds. These are colored and have UV protection properties. It is used in the form of a scrub to diminish sun damage on skin [57-60].
2.10. Herbs With Antiseptics Effects
Natural antiseptic herbs are used to kill or inhibit the growth of microorganisms when applied to a living tissue or skin. Antiseptic medicinal herbs reduce the possibilities of infection, sepsis or putrefaction. Plants are a rich source of antibacterial agents with chemical defense against predation or infection. Morus alba, Ocimum sanctum, Oxalis corniculata, Piper nigrum, and Syzygium aromaticum belong to this category [61-64].
2.10.1. Clinacanthus Nutans
It is well known because of its various medicinal uses. Clinacanthus nutans or Sabah snake grass is a small shrub that belongs to the family of Acanthaceae and can be found in South East Asia. Ethyl acetate fractions from leaves of this plant are effective against Bacillus cereus, Escherichia coli, Salmonella and Candida albicans that use minimum inhibitory concentration and minimum bactericidal or fungicidal assays [65-68].
It is extensively used as spice, food preservative and coloring material in India, China and South East Asia. Various sesquiterpenes and curcuminoids have been isolated from the rhizome of Curcuma longa. They are used in anti-inflammatory wound healing, anticancer and antibacterial activity. Skin conditions such as acne, alopecia, atopic dermatitis, facial photoaging, pruritas and psoriasis. Antioxidants in turmeric protect the skin cells from free radical damage and quickly recover all kinds of wounds due to its antiseptic qualities [69-71].
The latest trends in beauty, health and well-being have given rise to a new realm of possibilities by fusing with traditional Indian medicine. They are useful for exploration of possibilities of developing new anti-aging cosmeceuticals with natural ingredients for topical applications. The future for beauty-from-within functional cosmetics is bright, because of multifunctional benefits in the area of anti-oxidant cellular protection and skin health with anti-inflammatory and anti-stress properties. Green tea helps to treat acne sores, while Manjishtha purifies the blood and indirectly facilitates skin. Aloe vera soothens the skin, sandalwood brightens the skin. used as an astringent, while rosemary hydrates the skin. Apricot helps to fight the wrinkles. Papaya and cucumber have an important role in the treatment of pigmentation. Witch hazel and white oak act as astringents. Carrot and Gingko act as astringents. Pumpkin and walnut are rich in sun-screen effects. Turmeric is a beneficial antiseptic. Backed by sound science and substantiated structure and function, they offer huge benefits to the cosmeceutical sector. This review may help cosmetic and personal care industry, marketers and modern scientists to understand different trends of potential use to research cosmeceutical approaches to deal with the problems associated with derma care.
In India, more than 70% of the population prefers herbal cosmetics for their health care. Current scenario shows that herbal cosmetics have been marked up in personal care system and there is a great requirement for herbal cosmetics in daily life. The chemical formulation of all these cosmetic products includes the addition of various natural additives, like waxes, oils, natural colours, natural fragrances and parts of plants like leaves. There is need to do more Research and Development in the field of herbal cosmetics to prove effectiveness and include herbal cosmetics in safety profile. It is important to conduct adequate safety testing as per existing regulatory rule and present requirements. Quality control for ability and safety of herbal cosmetic products is of predominant importance, although it is assumed to be safe for longer periods of time.
