Affordable Nivea Moisturizer
Clinique at a moderate price
There is Ambrose, known as the great treasure of France, but the price is higher than the other two.
Twenty-five volunteers were selected to test their skin moisture content, skin health status and barrier function, and then the effectiveness of the product was measured according to the data comparison after using the product.
Volunteers were asked to draw blindly. Clinique was used in group A, Ambrose in group B and Nivea in group C.. After applying it twice a day for three weeks, the researchers found that it is not the most expensive product among the three that has a good hydrating effect, but the volunteers with the lowest price product, and the skin moisture content increases most obviously; The most expensive moisturizing cream has poor hydrating effect.
The researchers said that it is unwise to judge the moisturizing effect of products only by price, and that the more expensive the better. Next, they observe whether the user's skin has improved. The researchers found that these three products did not improve skin health at all, let alone anti-aging. After careful observation, the expert group believes that there is no difference between using products and not using products, and the level of skin health has not changed.
As for long-term use, can it reduce wrinkles? Experts say no, what we can see with the naked eye is actually only the short-term effect brought by the product. Therefore, the documentary concludes that there is no absolute anti-aging moisturizing cream in the world.
A girl at the scene said a lot of people's inner words:
Does this truth surprise you? ! If you want to make your skin white and beautiful by using skin care products, you may have miscalculated!
Wang Baoxi, the chief physician of the Department of Dermatology, Plastic Surgery Hospital of China Academy of Medical Sciences, pointed out on March 22nd, 20 17 that skin care products are just like "health products" rather than medicines, and have no such strong functions. Don't expect a certain skin care product to make the skin change quickly and achieve whitening effect.
These kinds of skin care products are pure money!
Hu Xiaobo, a skin care R&D engineer who graduated from the Biology Department of Fudan University and is one of the top 500 companies in the world, pointed out in an article on the popular science website that these skin care products actually make you pay IQ tax!
1, deep hydration?
Deep hydration is often heard in advertisements, such as: let the skin drink enough water. ......
Deep hydration? Forget it! Our skin, except the cuticle on the surface, never lacks water in the deep layer, because all this water comes from the subcutaneous tissue, where 70% is water and does not need external supplement. Besides, I can't make it up if I want to.
2. Apply collagen?
Apply collagen directly, want to protect skin? No way! Collagen is a kind of "macromolecular" structure, and the channels in human skin are very small, so it is basically impossible for collagen coated on the face to be absorbed by the epidermis. Oral collagen can't make up the face! Collagen after eating will be decomposed, and after being absorbed as a nutrient, it may not be able to combine into collagen and act on the face accurately. Oral pearl powder, resveratrol and grape seed essence are also unreliable.
3. stem cell skin care products?
99.9% of stem cell products are unreliable, and reliable ones will not use these three words for publicity. Because: no cells can survive in skin care products, let alone stem cells.
The so-called stem cells are differentiated cells that exist in the skin. Once the skin is damaged, they can be repaired quickly. The animal stem cells and plant stem cell promoted by some products are just common extracts, and there is no such thing as "cells". Even if there is stem cell extract, it is not the same as the stem cells in your skin. Therefore, seeing the words "stem cells", rational consumers can immediately put down their products, wash and sleep.
4. Placenta/cord blood essence?
The concept of placenta is scary enough. As soon as the umbilical cord blood came out, it was immediately compared. Don't try this kind of unknown composition, it is risky. In fact, whether it is umbilical cord blood or placenta extract, the effective components of such products are unknown, the batch stability is poor, and there may be virus pollution and harmful hormones. Therefore, for these new and exotic products, there is a strange effect of the legend that "the skin will be much better the next day", so be careful to plant grass.
5. Anti-aging?
Can anti-wrinkle cream prevent skin aging? The answer given by Australian dermatologists is: No, Schumacher, a professor at the Australian Dermatology Society, said that there is no evidence that anti-aging cream has anti-aging effect. Some skin care products contain peptides that promote the growth of collagen and elastin; Some also contain vitamins A and C, which can help repair damaged cells. But these effects are all theoretical, and there is no practical evidence that they play an anti-aging role.
Ultraviolet rays can promote skin aging and increase wrinkles. Therefore, Schumacher believes that the only way to really slow down skin aging is sun protection. If you want to slow down skin aging, a better way is to use sunscreen and wear a hat to avoid direct sunlight.
6. Quick whitening?
Yang Yang, director of dermatology department of Guangdong Armed Police Corps Hospital, reminded everyone that whitening is a gradual process in an interview with Health Times reporter on June 17, 2003. Beware of some whitening creams and masks that turn white after use. This immediate whitening effect may be caused by too much whitening phosphor.
It is allowed by the state to add fluorescent agent to whitening products, but some unqualified products on the market will be added in excess in order to achieve quick results, which may cause cancer. Dermatologists have long pointed out the truth of skin care: the simpler the better!
1, Cleanliness: Clear water is the best skin care product.
Guo Guowei, a famous Chinese doctor and director of the Institute of Dermatology of Guangdong Provincial Hospital of Traditional Chinese Medicine, is over eighty years old, but his face is ruddy. On April 20 14, in an interview with the Health Times reporter, he pointed out that if you want Yan Ruyu, you should wash it with clean water. In his eyes, clean water and even tap water are the best cosmetics. The old man said that the south is warm and humid, and there is a lot of oil secretion on the face. You must wash your face frequently. After a nap, you will secrete more oil and wash it with water. If you come home from a dusty outdoor and feel dirty, use some facial cleanser appropriately.
2, moisturizing: the past "clam oil", the most common vaseline.
Chen Tongyun, the chief physician of dermatology in Beijing Hospital of Traditional Chinese Medicine, is over 90 years old, and her skin is still fair and delicate, without any wrinkles. In the program of Beijing Satellite TV Yangshengtang in March 18, she said that she actually didn't have any special maintenance methods, and the skin care products she used were very simple, which was almost: clam oil in the past, the most common vaseline. Her "secret recipe" is to clean the face with ordinary facial cleanser and then apply some skin care products made by herself. There is nothing particularly valuable.
3, anti-aging: sunscreen all year round.
Wang Baoxi, chief physician of Department of Dermatology, Plastic Surgery Hospital, China Academy of Medical Sciences, told Health Times reporter on April 27th that photoaging is the main cause of skin aging. The sun will tan our skin, accelerate skin moisture loss and skin aging, aggravate freckles, and may breed wrinkles. The secret to aging skin is to avoid light and sun protection.
If there are few outdoor activities, you usually stay indoors, and you should apply sunscreen every day in summer. If you have a lot of outdoor activities, you'd better wear sunscreen all year round. Under normal circumstances, choose SPF20-30 sunscreen, and apply it every 2 hours if possible; Choose sunscreen above SPF50 when going to the seaside, and wear a hat and sunglasses when going out.
