Dry sensitive skin lacks water without using "oil"? The chemical composition in skin care products makes sense!

It is recommended that sensitive skin partners with dry skin pay special attention to moisturizing, but there are still many people who don't understand. Why do you obviously use moisturizing skin care products?
In fact, I said that the lock is moisturizing, and it is really water that is locked with grease.
Because for dry sensitive skin, the demand for oil to protect the skin is greater than the need for water.
Since the skin itself hardly secretes oil, the skin layer lacks a protective film to block the evaporation of moisture and oil, and the skin naturally becomes dry.
Therefore, extremely dry skin requires a sufficient supply of oil.
This layer of grease film prevents moisture loss, smoothes the skin, and reduces the skin's irritation to the skin. It can be said to be a protective barrier.
Therefore, the "oil" in skin care products is very important for sensitive skin. If you only apply water without lotion or cream, skin dryness will soon appear.
Skin tingling, peeling, itching, and a lot of small rashes, these are the performance of sensitive skin lack of water.
Therefore, as a dry sensitive skin, you should not feel refreshed when choosing skin care products. Be sure to pay attention to whether its "greasy" can help you moisturize.

What are the "oils" we need?

Vaseline
The most common skin care oil we have, the Vaseline is none other than it.
Vaseline is a semi-liquid mixture of paraffinic or saturated hydrocarbons, also known as petrolatum, which is fractionated from petroleum.
This is an excellent encapsulating agent, which can be applied to the skin to seal the skin well and prevent the skin from losing moisture.
The same effective oils are lanolin, mineral oil, silicone derivative polydimethylsiloxane, and cyclic polydimethylsiloxane.
They are also the ingredients of the envelopes that are often added to all types of moisturizers.

glycerin
Glycerin is also an "oil" that everyone is familiar with, but strictly speaking, glycerin is really not an oil. It is only a skeleton component of triglyceride molecules. Its chemical name is glycerol and it belongs to polyols.
Glycerin is a good solvent and hygroscopic agent that absorbs moisture from the environment, so it is a moisturizer ingredient in moisturizers.

Silicone oil
There is also an "oil" that is dispelled by shampoo ads - silicone oil. In fact, dermatologists do not disregard silicone oil because silicone oil is really useful and good for the skin.
Silicone oil is usually referred to as "dimethicone", which is a substance that is liquid at room temperature. The external use is basically harmless to the human body and has a good lubricating effect.
Remember not to be scared by the chemical composition behind it when choosing a skin care product, because there are many that are really needed by our skin.

Regular skin care products, their formulations have been tried and tested through numerous trials and experiments.
Only if it is not suitable for you, there is no dangerous component, and the partners can use it with confidence.
