Embodiment 1

[0026] Different molecular weight hyaluronic acid (3K-7K, 7K-10K, 10K-100K, millions of D), the decomposition speed is different. The smaller the molecular weight, the faster the rate of catabolism. This product is used twice a day, using 3-7K Dalton hyaluronic acid, which can fully maintain skin moisture without adding extra burden to the skin.

[0027] Oat β-glucan can promote self-synthesis of collagen, and the absorbed hyaluronic acid combines with collagen for hydration and better water retention. In this example, two or three schemes of hyaluronic acid + collagen, hyaluronic acid + oat β-glucan, hyaluronic acid + oat β-glucan + allantoin were tried, and the experiment was carried out in the spring season when people are prone to allergies , 50 women aged 25-35 were selected in each of the three groups. There were no facial skin problems at the time of selection, and there were 16, 14, and 17 people with a history of skin problems in the three groups respectively. Use i...

Embodiment 2

[0032] (1) Pre-heat the pure water to 80°C, keep it warm for 20 minutes, then lower it to room temperature for use, and replenish 4% of water;

[0033] (2) In the reaction kettle, add water 92g, butanediol 2g, trehalose 2g, oat β-glucan 2g, sodium hyaluronate 0.5g, allantoin 0.2g, dipotassium glycyrrhizinate 0.2g, hydroxyl Benzyl ester 0.2g, stir and heat up to 80°C, stir at 25rpm, stir for at least 30min, until the dispersion is uniform, then cool down at a uniform speed for 1°C / 2min;

[0034] (3) When the temperature drops to 45°C, add 0.2g of phenoxyethanol and 0.2g of ethylhexylglycerin, stir at 15rpm, and cool down at a uniform speed for 1°C / 2min after the dispersion is uniform;

[0035] (4) When the temperature drops to 40°C, add 0.2g of paeoniae officinalis root extract, 0.2g of peony root extract, and 0.2g of 1,3-propanediol, and stir for 15 minutes until the mixture is evenly dispersed;

[0036] (5) When the temperature drops to 35°C, take a sample to detect the phys...

Abstract

The invention discloses ethanol-free aqueous essence used for preventing and repairing multiple skin injuries. The ethanol-free aqueous essence is characterized by being prepared from the following raw materials in percentage by weight: 0.5-20 of butanediol, 0.5-5 of oat beta-glucan, 0.5-5 of trehalose, 0.05-2 of sodium hyaluronate, 0.05-8 of plant root extract, 0.05-5 of 1,3-propylene glycol, 0.05-2 of allantoin, 0.05-3 of an antibacterial agent, 0.01-2 of a preservative, 0-0.2 of disodium EDTA and the balance of water, wherein the total weight percent of the raw materials is 100%. The obtained essence has multiple functions of activating skin, resisting wrinkles, moisturizing, resisting inflammation and repairing keloid scars.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to an alcohol-free water essence for preventing and repairing various skin damages and a preparation method thereof. Background technique [0002] Healthy skin moisture content should be maintained within a certain range. If it is low, the skin will be dry, rough, lack luster, and even desquamated; if it is high, it will damage the barrier function, prone to acne, increased sensitivity, infection and various skin problems. The water content of the stratum corneum of the skin should be maintained between 10-30%. Hyaluronic acid can lock in moisture. Insufficient hyaluronic acid will cause water shortage. Excessive hyaluronic acid will cause excessive water content in the skin, which will increase the permeability of the skin and reduce the barrier function, which will cause various skin problems. As the age increases, the skin loses hyaluronic acid and the skin will be dehydrated. However, ...
