Development and characterization of a natural herbal face pack for sebum management and skin hydration

Introduction

Cosmetics are products used to cleanse, beautify, enhance attractiveness, or change one's appearance. Various herbs are utilized to cleanse and enhance our faces. Herbs have been utilized for many reasons since ancient times [1]. The Greek term "kosmtikos," which means "having the power and skill in decorating," is where the word "cosmetic" originated [2]. An individual's skin depends on a number of things, including their health, lifestyle, regular work, climate, and upkeep. Overexposure to heat causes the skin to become dehydrated throughout the summer, which results in sunburns, wrinkles, freckles, pimples, and pigmentation. The harsh winters lead our skin to become cracked, cut, macerated, and infected. The Drugs and Cosmetics Act of 1940 defines a cosmetic as any substance that is meant to be rubbed, poured, sprinkled, or sprayed on, introduced into, or otherwise applied to the human body or any part thereof in order to cleanse, beautify, promote attractiveness, or alter appearance. Herbal cosmetics are preparations that contain phytochemicals from a range of botanical sources, which affect skin functions and supply nutrients required for healthy skin or hair. The adverse effects of these cosmetics are lower than those of the others. Natural herbs and their products are employed in cosmetic preparation because of their aromatic value. These organic herbs improve the health of our skin [3].

herbal face pack

The Ayurvedic word for the herbal paste used to cure facial pigmentation, scars, marks, acne, and pimples is "mukhalepa." Nowadays, this herbal concoction, called "mukhalepana," is often applied as a facial cosmetic procedure. A mild powder is also applied to the face as part of the "face pack" idea. A good herbal face pack should not only improve the skin's appearance but also reach the subcutaneous tissues and supply vital nutrients [4,5]. A face pack is a smooth powder that is applied to the skin. After being applied to the face, these liquid or paste-based preparations are let to dry and solidify into a film that strengthens, tightens, and cleans the skin. They are commonly applied to the skin for 15 to 30 minutes to let the water drain. This causes the film to compress and solidify, which simplifies removal. While the tightening and warming properties of the face pack offer the illusion of a regenerated face, adsorption and colloidal clays in these preparations help remove oil and debris from the face's skin [6] . The natural face packs are less complicated and relatively easy to use. They assist us in improving the flow of blood via the facial veins. The effects of the face packs are usually transient. For consistent radiance, use it two to three times a week [7]. These days, a variety of packs that are easy to use based on the skin type are available individually for oily, normal, and dry skin. Face packs must be used frequently to improve the skin's smoothness and fairness. Regular use of the face pack eliminates wrinkles, acne, pimples, and dark circles on the skin. Face packs which are recommended for oily skin prone to acne, black heads usually control the rate of sebum discharge from sebaceous glands and fight the harmful bacteria present inside acne lesion.Herbal face packs are widely utilized because of their many advantages over chemical-based packs. They don't cause toxicity, allergies, or habit formation. They are natural in every way and have a long shelf life. They can be simply prepared and kept for a longer period of time without the need for preservatives [8]. [9,10] 1. Depending on its herbal elements, helps lessen scars, marks, acne, and pimples. 2. A face pack typically eliminates dead skin cells. 3. The effects of these face packs are calming and relaxing. 4. Frequent use of a natural face pack improves the texture and complexion of the skin and gives it a glow. 5. The appropriate usage of face packs can successfully counteract the negative effects of pollution and severe weather. 6. They aid in preventing early skin aging. 7. Natural face masks are an effective way to prevent wrinkles, fine lines, and sagging skin. 8. A natural face pack gives the skin a youthful, healthy appearance.

Benefits of Applying Face Pack

Precautions to be taken while applying Herbal Face

Pack [11]  Choose a face pack based on the type of skin you have. Before using a face pack, get advice from a natural skin therapist or a concerned skin specialist.  Don't leave the face pack on your face for longer than fifteen to twenty minutes. If the face pack is used for an extended length of time, wrinkles, skin sagging, and an increase in open pores may result.  Avoid scratching the dehydrated face pack. Water at room temperature must be sprayed on the skin before to removing the dry face pack. After taking off the face pack, apply an ice cube to the skin on the face for a calming effect. This tightens the skin and helps to seal open pores. It also tones and calms the skin.  Applying a face pack on allergic skin is not advised.  Avoid scrubbing your face too hard as it could cause dark stains and pimples to appear.  Avoid heat sources after applying a face pack.  Because the skin around the eyes is so sensitive, face packs shouldn't be used close to the "eye zone." The skin surrounding the eyes may be harmed during the removal of a face pack.

1.1 Ideal properties of a Herbal Face Pack [12]  It must be non-irritating and non-toxic.  It should be physically and chemically stable.  Gritty particles should not be present.

 The smell should be pleasant.

Materials 2.1 Urtica Dioica

One of the most popular medicinal plants, it is valued for its many health-promoting properties, accessibility, and nontoxicity [13,14]. Several phytochemicals from the family of secondary metabolites, including as terpenes, phenolic acids, flavonoids, chlorophylls, carotenoids, and fatty acids, are abundant in the plant [15,16,17,18,19].

Additionally, nettle extracts are used in cosmetics, and topical use has several benefits for skin health (including anti-inflammatory and anti-swelling qualities). However, nettle extracts are among the most intriguing substances for cosmetic applications due to their antioxidant and anti-aging properties. Because it gathers a variety of reactive oxygen species scavengers, nettle has anti-aging qualities that might lessen free radical damage to the skin [20][21] . Apart from its antioxidant qualities, the anti-aging effects can also be ascribed to the suppression of degrading enzymes such as collagenase or elastase, which reduce skin suppleness and lead to wrinkles [22]. Quercetin and ursolic acid are two substances present in nettle extracts that are especially promising for the development of anti-aging action [23,24]. While quercetin, one of the most well-known antioxidants, is largely present in leaves [26], ursolic acid, a well-known elastase inhibitor, is mostly found in nettle roots [25]. Its exceptional antibacterial and antifungal properties also make it an excellent component for skin care [27] A) Urtica dioca leaf B) stem

Papaya powder

Papaya (Carica papaya), a tropical fruit in the Caricaceae family, is rich in bioactive phytochemicals with antioxidant qualities such benzyl isothiocyanate [29] and dietary antioxidants include vitamin C, tocopherols, total phenols, and β-carotene [28]. Papayas contain the papain enzyme, which functions as a natural exfoliator to help eliminate dead skin cells and enhance skin texture. Additionally, it includes vitamins A, C, and E, which protect and nourish skin. It can also be used to soothe damaged skin and treat sunburns because it contains a lot of healing enzymes. Papaya powder's flavonoids stimulate the skin to make more collagen, giving it a firm, supple, and velvety tone. [30].

Rose water

One of the oldest plants is the attractive and oil-rich rose.

The genus Rosa has over a hundred different kinds of vines and shrubs. The plant has been utilized in the medical and cosmetic domains due to its numerous attributes [31]. By retaining moisture, it functions as a natural humectant, keeping the skin soft, smooth, and moisturized. Its antiinflammatory qualities lessen redness, inflammation, and swelling, which helps calm sensitive or acne-prone skin [32]. Rose water's antioxidants also protect the skin from free radical damage and environmental stresses, postponing the development of premature aging and encouraging skin restoration [33].

Multan mitti (fuller s earth)

Multani Mitti, another name for Fuller's Earth, is a versatile skincare ingredient with several benefits. By reducing pore size, removing freckles and sunburns, and eliminating blackheads and whiteheads, it helps create a smoother and more even complexion. Multani Mitti effectively detoxifies the skin with its natural cleansing properties, removing excess oil and pollutants and enhancing blood circulation for a healthier and more luminous complexion. Packed with essential nutrients, Multani Mitti cures acne and minimizes imperfections, leaving skin smoother and more evenly Toned. Magnesium chloride also contributes to its skinfriendly properties [34,35].

Glycerine

Glycerol is a thick, colorless, odorless liquid that is also sold under the brand name glycerin. Food, cosmetics, pharmaceuticals, and polymers are just a few of the many industries that employ glycerin [36]. Because glycerin retains moisture, the skin remains hydrated, smooth, and supple. Because of its anti-inflammatory properties, it can lessen redness and inflammation in skin that is inflamed. Additionally, glycerin aids in shielding the skin from environmental stresses including wind, cold, and dry air. Glycerin makes skin more flexible, which lessens the appearance of fine lines and wrinkles. Dark patches and hyperpigmentation might be less evident by brightening the skin with glycerin [37]. 2.6 Raw material and formula for formulating herbal face pack: The herbal face pack was prepared using natural ingredients selected for their cleansing, sebum control, exfoliating, and moisturizing properties. Each component was carefully weighed and blended to obtain a uniform and smooth powder formulation suitable for topical application. The composition of the polyherbal face pack and the functional role of each ingredient are presented in Table 1. Papaya powder Exfoliation: uses the natural enzyme papin to exfoliate dead skin cells. 10 gm

Methodology 3.1 Process of formation of herbal face pack: step-bystep

Choosing natural herbs that work well for various skin types is part of creating a herbal face pack. To treat particular skin issues like acne, dryness, pigmentation, or aging, a blend of these components is created. [39] This is a complete, step-bystep procedure with theoretical justification:

Step Step 2: Preparing the base of the face pack The consistency and application of a face pack are greatly influenced by its base. Common bases are powders or clays that create a paste when combined with liquids. Additionally, the base establishes the main purpose of the pack, such as hydration or oil absorption.

Step 3: Mixing the ingredients When the chosen components are mixed together, their chemical characteristics work in concert to offer a variety of skin benefits. The base is multanimitti, which has great cleaning and oil-absorbing qualities. Papaya powder exfoliates dead skin cells, while urtica dioica helps control sebum production and lessens inflammation. Rose water and glycerine help to hydrate, calm, and tone skin, giving it a smooth, nourished, and well-balanced appearance [38] .

Add base materials

Take the required quantity of Multani mitti as the main foundation.

It absorbs extra oil, gets rid of debris and pollutants, and gives the face pack a smooth base.

Add herbal powders

Add papaya and urtica dioica powder to the base gradually. Papaya powder promotes skin renewal and exfoliation, while urtica dioica helps regulate sebum production.

Add liquid component

To get a smooth, spreadable mixture, gradually add the glycerine and rose water while stirring continuously. [38] Rose water calms, tones, and hydrates the skin, while glycerine holds onto moisture and keeps the skin from drying out.

Add preservatives

Finally, incorporate a tiny quantity of sodium benzoate into the face pack. Without changing the face pack's texture or advantages, sodium benzoate prolongs its shelf life and protects the formulation by stopping microbiological development . [39] Consistency adjustment Add a little extra liquid (rose water) if the pack is too thick.

For a smooth, spreadable paste, add extra powder if it's too thin Step 4: Application of the face pack  Effective skin penetration of the active substances is ensured by proper application. The face pack works best when applied to dry, clean skin.  Clean the skin. To get rid of pollutants, oil, and dirt, wash your face with a mild cleanser. This guarantees that surface-level dirt won't interfere with the pack's ingredients' ability to function. [38]  Apply evenly: Avoid the areas around the lips and eyes when applying the face pack. Use your fingers or a brush.  The uniform distribution guarantees that the substances are beneficial to every area of the skin. [39] Fig 8: Application of the face pack

Step 5: Let the Pack Sit and Dry When the pack is applied to the skin for a set amount of time, the active substances have a better chance of penetrating the skin. When using clay-based packs, drying also helps remove excess oil and impurities from the skin.  Let it sit on your face for ten to fifteen minutes. If there is clay in the pack, it will begin to dry. This helps to Tighten pores and remove excess oil . [39]  The pack may stay moist if moisturizing substances like glycerine are used, providing hydration and calming properties.

Watch for skin reaction

Always perform a patch test to check for any allergic reactions or skin sensitivity before applying a face pack to your entire face.

Step 6: Rinse off  Rinsing the face pack eliminates any absorbed contaminants as well as the active ingredients.



After the procedure, proper removal guarantees that the skin won't feel dry or irritated.



Use warm water to rinse. Use lukewarm water to gently rinse off the face pack.



To exfoliate dead skin cells, gently massage your face in circular motions with your fingertips while you rinse.



After washing, use a gentle towel to gently dry your face. After treatment, the skin may become sensitive, so avoid rubbing.

Step 7: Moisturize  Applying a moisturizer is crucial to seal in moisture and stop moisture loss because the skin may be a little dry or irritated after using a face pack.  Use an appropriate moisturizer To restore moisture balance, use a heavier cream for dry skin or a lightweight, non-comedogenic moisturizer for oily  Skin.

Evaluation Studies

Physicochemical evaluation Moisture content, extractive values, pH, and ash levels were among the physicochemical parameters that were determined. [40] Organoleptic evaluation: The physical characteristics of the material were manually assessed using organoleptic parameters, which include its nature, colour, odour, feel, and consistency.

Angle of repose:

A granular material can be stacked on a horizontal surface at the steepest angle without sagging.

Discussion

The present study focused on the formulation and evaluation of a Polyherbal face pack containing natural ingredients such as Multani mitti, Urtica dioica, papaya powder, glycerine, and rose water for sebum management, exfoliation, and skin hydration. The selection of herbal ingredients was based on their traditional use and reported dermatological benefits. Multani mitti acted as an effective oil-absorbing agent and helped in deep cleansing of the skin pores. The inclusion of Urtica dioica contributed to sebum regulation and helped reduce excessive oiliness, while papaya powder provided mild exfoliating action due to the presence of natural enzymes that aid in the removal of dead skin cells. Glycerine served as a humectants that enhanced moisture retention, and rose water helped in soothing the skin and maintaining pH balance. The formulated herbal face pack showed desirable physicochemical properties including smooth texture, good spreadability, and ease of application. The consistency of the formulation was found to be appropriate for topical application without causing discomfort. The washability of the face pack was satisfactory, and no irritation or redness was observed during the skin compatibility test, indicating that the formulation is safe for routine use. The pH of the formulation was found to be within the acceptable range for skin application, which helps prevent skin dryness and irritation. Overall, the combination of selected natural ingredients demonstrated synergistic effects in providing cleansing, exfoliation, oil control, and hydration. The developed formulation was found to be stable, safe, and effective for routine skincare application. This study supports the use of Polyherbal formulations as a natural alternative to synthetic cosmetic products, offering multiple skin benefits with minimal risk of adverse effects.
