Description

sunscreen

technical field

The invention belongs to the technical field of daily chemicals, and more specifically relates to a sunscreen.

Background technique

The ultraviolet rays in the sun are the main factors that cause skin aging and the formation of spots on the skin surface. Even in spring, if one is allowed to expose to the sun for ten minutes, the skin will age ten days prematurely.

The damage of ultraviolet rays to the skin mainly includes the following points:

1. Increase melanin synthesis. It can lead to hyperpigmentation, such as dark spots, freckles, chloasma, etc. The increase, increase, and darkening of various spots;

2. Hyperplasia of keratinocytes, destruction of dermal collagen fibers and elastic fibers. Can cause skin hypertrophy, sagging, roughness and wrinkling;

3. Telangiectasia can produce erythema;

4. Decreased skin immune function. Can form skin cancer or precancerous lesions, such as actinic keratosis, squamous cell carcinoma, melanoma, etc.

At present, in the outdoors, the skin is usually protected from ultraviolet rays by applying sunscreen to the skin; the principle of sunscreen is to isolate the skin from ultraviolet rays, thereby preventing the skin from being sunburned.

There are two types of sunscreens: physical sunscreens and chemical sunscreens.

Physical sunscreen, as the name suggests, is to use the principles of physics for sun protection; the atomic particles of this sunscreen are flakes, and when applied on the face, they reflect sunlight like a mirror to achieve the purpose of sun protection. Titanium dioxide and zinc oxide are both physical sunscreen ingredients. They form a protective film on the skin that prevents UV rays from penetrating the skin's surface. However, this type of product also has certain limitations: for people with darker skin, the touch-up effect may not be natural; for people with dry skin, it is not moisturizing enough; it is not suitable for full body sun protection; must use makeup remover products to help Remove it cleanly; due to technical difficulties, the particles are often too large, making the use feeling thicker and airtight, etc.

Chemical sunscreen is to use chemical ingredients to prevent sunscreen; this kind of sunscreen uses the principle of absorption to prevent sunscreen. It is a light-transmitting substance that can absorb ultraviolet rays and convert them into molecular vibration energy or heat energy to achieve sunscreen effects, such as amino Benzoic acid and its derivatives, cinnamic acid, etc. When applied to the face, the atoms absorb sunlight to prevent it from reaching the skin.

In theory, physical sunscreens are better than chemical sunscreens, but most of the sunscreens on the market are chemical sunscreens.

Common chemical sunscreens usually contain harmful chemical components and heavy metal elements, which are prone to greasy feeling when used and need to be reapplied frequently; and if used more often, it is easy to cause skin allergies, and even more serious, it will cause certain irritants in the human body. harm. According to a survey report covering 785 well-known cosmetic brands, 84% of the sunscreens with an SPF of 15 or higher on the market today do not provide enough protection for the skin from harmful rays, or contain ingredients that are harmful to the skin. Element. Even though some sunscreens claim to have sun protection function, they "melt" when they encounter sunlight.
