THE PRINCIPLE OF WHITENING
The colour of human skin is mainly determined by the skin’s content and distribution of melanin. The most critical step is controlling the formation of melanin by controlling the tyrosinase in the human body. The role of active whitening ingredients in whitening cosmetics prevents the biosynthesis of melanin or activates the anti-free radical ability of human epidermis and dermal cells. It can promote the metabolic renewal of epidermal pigment cells, reduce the degree of pigmentation and hyperkeratinization of the epidermis, and make skin cells elastic and shiny.
DESIGN OF WHITENING COSMETIC FORMULA
The key to the formula is to grasp the mechanism of action of whitening and freckle removal, rationally compound the raw materials for whitening efficacy, select the emulsification system, and select the necessary additional raw materials. Efficacy of ingredients If a single active whitening ingredient is used, the whitening effect will not be obvious, and combining multiple ingredients can have a significant effect. Кроме того, the selection and compounding of the emulsification system, the anti-discolouration agent, the ultraviolet absorber and the oil phase all affect the system’s stability, appearance and effect.
1. Selection of dosage form
The whitening formula can be used in many forms: крем, лосьон, liquid (масло, вода), гель, sheet mask and clay mud. We can choose different dosage forms according to product characteristics and usage requirements. You can choose one of them or develop a series of products. If you make a series of products, it can provide the perfect whitening process for the skin. В то же время, it plays a role in sun protection, wrinkle removal, skin rejuvenation and repair to keep the skin moist and healthy while whitening.
2. Selection of functional ingredients
There are many ingredients for whitening and freckle removal, including physical, chemical and natural plant extracts.
Physical whitening agents, such as iron oxide, titanium dioxide and zinc oxide, are also called physical covering agents.
Whitening agents extracted from natural plants are kojic acid and its derivatives, hydroquinone, арбутин, fruit acid, provitamin B (ниацинамид), vitamin c and its derivatives, proteolytic enzymes, coix seed, mulberry, алоэ, Licorice extract, Scutellaria root extract and Morus alba extract, так далее. Whitening agents most used are safer and have better effects include arbutin, kojic acid and its derivatives, vitamin c and its derivatives, ascorbic acid-arbutin phosphate and plant extracts.
Chemical whitening agents are absorbed through the skin and can play the following roles:
① Inhibit tyrosinase activity: Mainly inhibit or reduce the production of skin pigment intermediates (pigment source) and melanin, such as hydroquinone and arbutin, так далее.
② Skin pigment reduction: Mainly to reduce and eliminate the produced skin pigment intermediates (pigment source), anti-oxidative free radicals and anti-ageing, such as vitamin C and its derivatives, vitamin P, так далее.
③ Dual effects of pigment reduction and tyrosinase inhibition: Such as ascorbic acid – arbutin phosphate can play a double whitening effect.
④ Increase the degradation and inactivation of the black particles of keratinocytes and promote and promote the timely exfoliation of the epidermis: Such as fruit acid, kojic acid and kojic acid esters, skin dead skin peeling agents, так далее.
⑤ Skin whitening: Some Chinese herbal medicines can selectively destroy melanocytes and inhibit the formation of black particles and degrading agents.
Поэтому, these factors should be considered when choosing a whitening agent. It can not only inhibit the activity of tyrosinase but also consider the lightening and reduction of the formed pigment and stain. Adding an appropriate amount of skin whitening agent (Chinese herbal extract) has a more obvious effect, and some formulas add ingredients to soften cutin and exfoliate dead skin. Regular exfoliation can penetrate and absorb the whitening ingredients more effectively, reflecting the skin care concept of deep purification combined with whitening and conditioning.
3. Selection of emulsification system
The emulsification system of whitening cosmetics generally chooses the o/w type, which has a better affinity with the skin and is conducive to the absorption of active ingredients. The emulsifier is generally a liquid crystal emulsifier, which makes the product feel good on the skin and can be absorbed well. В то же время, the paste made with it is beautiful and has a specific effect on maintaining the stability of active substances.
4. Selection of moisturizer
Whitening products must have good moisturizing properties, and an excellent moisturizing effect will facilitate the penetration and absorption of active ingredients. В то же время, it keeps skin cells plump and anti-ageing.
When choosing a moisturizer, you should consider both effectiveness and cost. Ordinary moisturizers, such as glycerin and propylene glycol, are cheap and have average moisturizing effects. Moderate humectants include amino acid humectants, marine polysaccharide humectants, reed gum oil, sodium pyrrolidone carboxylate, and complex humectants. Their moisturizing effect is ideal, but the cost is relatively high. Advanced moisturizers like hyaluronic acid.
5. Selection of synergists
Adding some moisturizing agents, keratinizing agents, and penetration enhancers are conducive to absorbing active ingredients and has a synergistic effect. Кроме того, adding some ascorbic acid-tyrosinase inhibitors, vitamin B, и т.п., also has a synergistic effect on skin whitening.
6. Selection of other auxiliary raw materials
Adding UV absorbers can effectively block the external triggers of melanin production, play a whitening and protective role to a certain extent, and prevent skin sunburn and product discolouration. Adding softening keratinizes and pigment removers can reduce the concentration of melanin in the epidermis and accelerate the renewal of epidermal pigment cells. When the amount of active whitening ingredients added is high, it is easy to irritate the skin, and the appropriate addition of anti-sensitizers can eliminate skin inflammation. The addition of moisturizing and rejuvenating agents can delay skin ageing while whitening.
ISSUES TO BE AWARE OF
1. Absorption problems
The active ingredient’s degree of absorption determines the whitening effect. The addition of penetration-enhancing ingredients, moisturizing ingredients and keratin softening ingredients is conducive to the absorption of whitening ingredients.
2. Penetration problems
Applying a penetration enhancer ensures it can deeply penetrate the active ingredients of whitening into the epidermis and dermis. The ultra-fine active ingredient structure facilitates osmotic absorption.
HOW TO USE WHITENING COSMETICS CORRECTLY
Whitening products are prone to discolouration. No other protective ingredients are added to the formula, and there are almost no raw materials that keep the colour unchanged for 2 к 3 годы. From the selection of packaging, it can play a partial protective role. В общем, light-proof or vacuum packaging is used to avoid colour changes caused by light and air. Кроме того, products with a single whitening ingredient are more effective at night. Some anti-ultraviolet skin care products, such as sunscreen and moisturizing day cream, should be used during the day to protect the skin and maintain the whitening effect. And professional whitening products generally have day cream and night cream (take cream as an example) to use together. The night cream mainly emphasizes the whitening effect, and the day cream mainly emphasizes the whitening protection and the repair of damaged skin.
