The skin is the largest organ of the human body; it plays a crucial role in protecting the rest of the body from external agents, helps to regulate temperature and releases natural oils to keep the skin soft and supple. The skin has three layers: epidermis, dermis, and subcutaneous fat.
The skin contains many structures and cells. The epidermis, or outermost layer, supports the dermis, or the second layer of skin. It protects from dehydration and loss of heat by creating a barrier against water evaporation. The epidermis layer of the skin is made up of stratified squamous epithelium, and it is replaced by the basal cells that move up to replace dead cells. The dermis contains collagen, elastin, blood vessels, sweat glands, and hair follicles. The hair follicle is the most vital structure of the skin. The hair follicle is found at the base of each hair shaft. It produces hair and sebum, an oily substance that provides nutrients for the scalp and skin.
How to Choose the Right Facial Serum for You?
There are many types of facial serums available on the market, and it can be hard to know which one is best for you. A few things to consider when choosing your facial serum.
Firstly, you should assess your skin type; it will help you determine the type of serum you need for your skin. A serum can be oil-based or water-based, depending on your skin needs. Oil-based serums are more suited for those with dry skin. Water-based serums, on the other hand, are better suited for those with oily skin.
Secondly, it’s imperative to consider ingredients that are good for your skin type and what ingredients are bad for your skin type. Beauty consumers ought to pay close attention to any comedogenic or irritant ingredients that could cause breakouts or irritation to help combat the effects of acne and other skin conditions.
The Skin Care Ingredients to Watch Out For and What Causes Comedogenicity
The comedogenic rating is a measure of how likely a substance is to clog pores and cause acne. This rating is determined by conducting a test on the substance’s ability to stimulate the growth of keratinocytes, which are cells that produce keratin, proteins that form our skin’s outermost layer. The higher the number, the more likely these substances will cause breakouts. For example, anything with a rating of 4 or higher is certain to cause breakouts on sensitive skin types.
According to the U.S. National Library of Medicine, the word comedogenicity, and is derived from the word comedones. Comedones are known as small, flesh-colored, white, or dark bumps that give skin a rough texture. The bumps are caused by acne.
The Difference Between Irritants And Comedogenic And Why It Matters
Irritants are substances that cause an adverse reaction on the skin such as dryness, redness, or swelling. Comedogenic substances lead to acne breakouts by clogging pores. The following ingredients are known to clog pores. As such, if you have oily or acne-prone skin, it is best to avoid products containing the following ingredients:
- Sodium Laureth Sulfate
- Palm oil
- Coconut oil
- Wheat germ
This list is by no means exhaustive, but these ingredients are more comedogenic than the rest.
Meanwhile, irritants may have many factors. Irritation of the skin is mostly due to one or more of the following:
- Irritation and contact urticaria
- Contact allergy
- Photosensitive reaction
- acne genesis and comedogenesis
- Color changes of the skin and appendages
- Systemic side effects and other local side effects.
Skin irritation causes it to be inflamed. The inflammation of the skin is often induced by external agents such as chemical irritants, mechanical, thermal, climatic, UV and IR light.
Skin irritation often manifests itself in the form of erythema, dryness, scaling, itching, burning, and tingling symptoms. However, it is worth noting that most cosmetic-use ingredients will not produce acute irritation from a single exposure due to the level of usage recommended for each ingredient. Still, ingredients known for their propensity to irritate when combined may produce inflammation after repeated application on the same area of the skin, which is known as “cumulative irritation.”
Oil Serum vs. Water-Based Serum – What is the Difference?
Oil serums are typically thicker and heavier than water-based serums. They are also more moisturizing because they contain emollients.
Water-based serums are lighter in texture and weight. They are also easier to apply on the skin because they don’t leave a greasy residue on the skin after application.
Oil serums are often made with natural oils that hydrate the skin while water-based serums usually contain chemical ingredients that can dry out your skin over time.
Skin serums are a new beauty product that has quickly become more popular over the last few years. A skin serum is similar to f lotion or cream that has ingredients that penetrate deep into the skin, while water-based serums typically only moisturize the surface of the skin.
Are Oily Skin Types Suited for Oil Serums or Water-Based Serums?
Oil serums are typically thicker and richer than water-based serums. They can penetrate the skin and deliver the ingredients deep within the layers of skin.Water-based serums are lighter in consistency and can be applied more liberally to the skin surface.The best way to find out which serum type is best for you is by trying both types and seeing which one you like better.
The bottom line is skincare is one of the most important parts of our everyday routine. We spend a lot of money on it and we want to make sure that we are investing in the best products.
Many factors can influence your skincare routine, but there are three main ones to keep in mind: skin type, product ingredients, and skin condition.
There are several different skin types, but two main ones – oily and dry. Knowing which type you have will help you choose the right products for your needs. Oily skin should avoid products with heavy oils or too much fragrance because they will make it worse. Those with dry skin should look for moisturizing products that contain shea butter or jojoba oil because they will help hydrate your skin and make it less prone to itching and cracking. Thus, avoid choosing products that contain alcohol or petroleum, as these can dry out your skin.
