What is "Oily On The Outside And Dry On The Inside" Skin
What is "oily on the outside and dry on the inside" skin? How to do skin care of it?
First of all, it must be clear that in skin classification, there is no such skin type as "oily on the outside and dry on the inside". "Oil on the outside and dry on the inside" is a description of how the skin feels. In many cases, it can cause a feeling of "oil on the outside and dryness on the inside". Generally, there are three situations in which consumers will describe their skin condition as "oily on the outside and dry on the inside". They are: 1. Wrong choice of products for combination skin; 2. The skin barrier is damaged and the ability to lock water is reduced; 3. The sweat gland function is damaged or blocked.
Combination skin product selection error Combination skin is a common skin type, mainly manifested as enlarged pores on the forehead, nose, mouth, jaw, etc., strong oil secretion, prone to blackheads and acne, but insufficient sebum secretion on the cheeks, Easy to dry and lack of water. Combination skin has oily T-zone and dry skin on the cheeks.
Part of the combination skin feels oily in the T zone, mistakenly thinking that they have oily skin, and like to use oil-controlling and refreshing products. These products usually contain oil-absorbing and oil-controlling ingredients. High-concentration alcohol is standard, plus cleansing products with strong cleaning power. The oil secretion in the T zone is strong, showing the characteristics of oily skin. Appropriate use of such products will not cause damage to the skin.
But for combination skin, the cheek sebum secretion is not excessive, and even somewhat insufficient. In the hot season, if you use an instrument to observe combination skin, you can see that the pores in the T zone are constantly expelling sebum, but the amount of sebum secretion on the cheeks is very small, or even unobservable.
If you use products suitable for oily skin on the cheeks of mixed skin, it will cause excessive cleaning and damage the sebum film; in addition, products for oily skin are generally refreshing, not moisturizing enough, and have the effect of absorption and oil control. The skin lacks the protection of the water-locking film, the water loss is accelerated, and the skin appears dry, tight, and dehydrated. Shows up as oily T-zone and dry cheeks. Many friends describe this situation as "dry on the outside and dry on the inside.
If this wrong skin care method lasts for a short time, it will generally not damage the skin barrier. As long as you adjust the product and take care of different areas, the skin will soon return to normal, and the symptoms of "oily on the outside and dry on the inside" will disappear. However, if the product is not adjusted in time, the skin function will be severely damaged and it will be difficult to restore it if the product is taken care of in this way for a long time.
◆ Nursing methods
If you want to avoid the problem of "oil on the outside and dry on the inside" of mixed skin, "zone care" is the best way. Use a refreshing product for the T-zone and a moisturizer for the cheeks. If you are not afraid of trouble, you can use two sets of products for the T zone and cheeks separately, or only distinguish between individual products. If you are afraid of trouble, you can also use a set of products and combine some small skills in the use method to achieve the purpose of partition care.
For example, if the lotion or cream is more moisturizing, you can use toner to dilute it in the palm of your hand when applying it on the T zone. If you don't use or reduce the amount of lotion (cream), you can achieve the purpose of partition care. There are many similar methods, and friends can use their wisdom and use them flexibly. To use a set of products for zonal care, you need to spend some thought when choosing products, taking into account the needs of different parts of the skin.
The skin barrier is damaged, and the ability to lock water is reduced. The outermost layer of the skin is a sebum film formed by the mixture of sebum and sweat. Below the sebum film is the stratum corneum composed of neatly arranged keratinocytes, and the intercellular space between the keratinocytes is filled. Moisture in the skin exists in three forms: free state, bound state, and encapsulated state.
The sebum membrane, stratum corneum, and intercellular substance together constitute the barrier of the skin, which resists the stimulation and damage of external foreign bodies and prevents water from evaporating. Most of the water in the skin combines with natural moisturizing factors, hyaluronic acid, etc. to form bound water, which locks in water and prevents water from evaporating.
Long-term use of anti-acne drugs, excessive cleaning, excessive use of products that peel off the cuticle, excessive skin care and other wrong skin care methods will damage the skin barrier, and the skin's natural moisturizing factor, hyaluronic acid and other water-locking ingredients will be lost too quickly. In the absence of protection, the evaporation of water is accelerated, the bound water in the skin is reduced, and the skin will feel dry and tight.
For oily skin and mixed skin, although the oil secretion is strong, the skin barrier is damaged, the natural moisturizing factor in the skin is lost, and the moisture cannot be effectively locked. Dry, dehydrated feeling. At the same time, the sebum secretion is high, and the skin is greasy. Causes the feeling of "oil on the outside and dry on the inside".
This symptom is more common in oily skin and mixed skin. The main manifestations are: dry skin, but strong sebum secretion, and greasy skin. Even the use of strong occlusive creams such as mineral oil and petroleum jelly cannot relieve the symptoms of dry skin. At the same time, the skin is relatively fragile and prone to allergies. Slightly irritated, it is prone to redness, tingling, itching, and even redness and swelling.
◆ Nursing methods
First of all, we must stop the wrong way of skin care. If it is caused by over-cleaning, adjust your makeup remover and cleansing products and avoid using products that are too strong. Gently removes makeup and cleanses face gently. Long-term use of cleansing products with strong degreasing power will not only cleanse the sebum on the skin surface, but also destroy the intercellular matrix, the skin barrier ability will decrease, the skin will release damaged signals, the sebaceous glands will accelerate the secretion of sebum, and the skin will become oilier. Aggravate the symptoms of "oily inside and dry outside".
Temporarily stop using all kinds of exfoliating products. For example, some products contain high concentrations of acidic ingredients such as fruit acid, salicylic acid, mandelic acid, and azelaic acid. Do not use products that contain high levels of alcohol. All kinds of exfoliating products should also be suspended. But there is no need to overcorrect. Some products contain very low amounts of acidic ingredients and alcohol, so don’t worry, you can continue to use them.
Long-term use of anti-acne drugs is also one of the reasons for the skin to be oily on the outside and dry on the inside. The first consideration of anti-acne drugs is the effect. Short-term use generally does not cause damage to the skin, but long-term use may damage the skin barrier. I saw many pictures sent to Zhen Yao by friends with acne. Because of long-term use of drugs, the skin is rough and scars appear locally, accompanied by itching, redness, allergies and other adverse reactions. If the acne is serious, it is recommended to go to a regular hospital to see a dermatologist, and do not buy medicines for long-term use without authorization.
Stop wrong skin care methods, avoid further skin damage, and stop damage in time. Then start caring for your skin. The basic principle of skin care is: streamline skin care, use only one product for each skin care step, and avoid excessive superposition. If it is not necessary, do not use sunscreen and make-up for the time being. You can use sun protection masks, sun umbrellas, sun protection clothing and other hard sun protection methods to protect yourself from the sun when you go out. If it is necessary to use make-up for work, you can only do basic care on the rest day to give the skin a chance to recuperate.
Directly replenishes moisture-locking ingredients to the skin. Glycerin, sodium PCA, B5, amino acid moisturizer, urea, lactate, hyaluronic acid, polysaccharides, sugar isomers and other ingredients can penetrate into the skin, lock in moisture, and assist the skin to restore normal functions. Most of the well-known moisturizing essences can meet the needs of the skin. If the skin is damaged due to excessive cleansing, oily on the outside and dry on the inside, keep using moisturizing essence, and the skin can recover quickly.
The function of sweat glands is damaged or blocked. There is also a kind of skin that is "oily on the outside and dry on the inside". The function of sweat glands is damaged or blocked, and the skin rarely sweats. When exercising or feeling excited, I often get flushed, but I don't sweat. We know that the sebum film on the surface of the skin is formed by mixing and emulsifying the sebum secreted by the sebaceous glands and the sweat secreted by the sweat glands.
When the sweat glands are abnormal or blocked, the sebum secreted to the surface of the skin lacks sweat emulsification, and cannot form a water-oil mixture similar to an emulsion, leaving only sebum, and the skin will feel greasy. The surface of the skin lacks the nourishment of sweat, and it will feel dry. At this time, it also feels "dry on the outside and dry on the inside".
