Questions and answers about natural beauty techniques

At present, the public's questions about natural beauty techniques focus on three aspects: the safety of homemade solutions, the true efficacy of natural ingredients, and the compatibility with different skin types. The other minor issues are basically an extension of these three categories.

To be honest, there are many people around me who have fallen into the trap of homemade natural beauty products. A while ago, a friend with dry skin followed the example of a blogger and used fresh lemon and honey to whiten his face. After applying it for three days, his cheeks immediately turned red and a small rash developed. He went to the hospital and was diagnosed with contact dermatitis. It took him a thousand dollars to repair it. There has been a lot of controversy on this point. Many people think that "all natural without additives are much safer than industrial skin care products." Many people also share their experience of using homemade facial masks to ruin their faces. In fact, from a dermatological perspective, the irritating ingredients in unpurified natural ingredients have not been removed. For example, the pH value of fresh lemon is only about 2, which is far lower than the normal weakly acidic environment of the skin. Applying it directly to the face will only destroy the barrier. Those who say it works without any problems after using it mostly have skin with extremely high tolerance. The skin condition is also stable during that time, so the method itself is not universally safe.

The second most asked question is the actual effect of various natural beauty methods. For example, whether drinking grape seeds can whiten skin, whether oral collagen peptides can resist aging, and whether matcha oil can lighten wrinkles. I am asked by my friends every now and then. This part is even more controversial. Some people say that they have not tanned in the summer after drinking grape seeds for three months. Others say that after half a year, there is no change at all. In fact, current clinical research has already given the boundaries: for example, small molecule collagen peptides can indeed be absorbed and converted by the human body, but the conversion rate varies from person to person. If you stay up until two or three o'clock every day and eat heavy meals No matter how much you drink oil and salt, you can't keep up with the loss of collagen in your skin. I drank a regular brand of small molecule peptides for two months. During that time, I deliberately went to bed early and didn't stay up late. When the season changed, I didn't have the same powdery and flaky skin as in previous years. But then I stopped and went back to a messy schedule, and my skin condition returned to its original shape. There is no one-and-done effect.

Another issue that is easily overlooked is that many people think that natural products can be used by everyone. In fact, there are many pitfalls in adaptability. For example, everyone thinks that aloe vera is soothing. A colleague of mine with sensitive skin was bitten by a mosquito in the summer. He used fresh aloe vera grown in the community to rub the wound. Not only did it not go away, but the swelling became larger and the mark remained for several months. This is because the emodin in the fresh aloe vera has not been processed, which is a strong allergen in itself. On the contrary, those with oily skin with high tolerance can apply refrigerated cucumber slices for ten minutes after sun exposure in the summer. The soothing effect on the redness is quite obvious, and there is no irritation reaction.

To put it bluntly, many people pursue natural beauty because they are essentially afraid of the risks of chemical ingredients. However, "natural" cannot be equated with "safety". If you really prefer natural beauty methods, it is better to start with a regular schedule and eat more fresh fruits and vegetables. This is a basic method that does not come into direct contact with the skin. The probability of getting into trouble is much lower.
