What are the issues with natural beauty techniques?

In fact, most of the questions related to natural beauty techniques revolve around the three core points of "will it hurt the skin, is it effective, and is it suitable for you?" There are far less bells and whistles than everyone thinks.

Many people who advocate natural skin care believe that the active vitamin C in fresh lemon is milder than synthetic ones and does not contain preservatives. The whitening effect of a thin application for 10 minutes is more obvious than dozens of essences. However, most dermatologists do not recommend using fresh lemon directly on the face. After all, its pH value is only about 2, which is far lower than the normal weak acid environment of the skin. It can easily damage the stratum corneum, and it is photosensitive. Sex, going out without washing off can easily cause spots. I have a friend with combination skin who applied fresh lemon slices before going to bed for three consecutive days in the summer to whiten her skin. On the fourth day, her face became red and stinging. It took almost two weeks to recover. There was also a girl who went shopping for a long time without washing off after applying the application. Two symmetrical light brown spots appeared on her cheekbones, which took half a year to fade away.

In addition to safety, the most controversial thing is whether this technique is useful. For example, the rice water used for face washing and skin rejuvenation has been passed down for many years. I tried it myself in the past two years. Every time I cook, I keep the second rice water and clarify it before using it to wash my face. I have persisted for more than half a month. My face does feel a little slippery to the touch and the oil is less, but it returns to its original shape after a week. I checked the relevant skin care literature and said that the small amount of starch and B vitamins in the rice water are indeed effective. It can temporarily absorb oil and soften surface cuticles, but these ingredients have high molecular weight and cannot penetrate the stratum corneum into the dermis, and cannot achieve the deep effects such as lightening spots and anti-aging that everyone expects. However, some skin care bloggers who have been using it for more than three years have shared that they have used warm rice water instead of cleansing all year round, and their original oily and acne-prone skin has gradually turned into neutral skin, and acne rarely occurs again. Both sides have their own arguments, and there is no unified conclusion yet.

In addition to these two points, the most easily overlooked issue is adaptability. Many people think that "natural is universal" and they can use it directly if others use it, without considering the difference in skin type. Take the most common application of cucumber slices on the face. If you have oily skin and get red in the summer, leave it on for 10 minutes. The effect of moisturizing and reducing redness is better than many expensive patch masks, and it is not sticky at all. However, if you apply it this way and don't apply facial cream in time to lock in moisture, it will It takes away moisture from the surface of the skin, making it drier the more you apply it. There is also aloe vera, which is known as the "skin care oil." Many people like to break off pieces of fresh aloe vera and apply it on their faces if they have sunburn or acne. If you have healthy skin, it will be fine. If you have sensitive skin, it will cause a lot of damage if you don't remove it. Fresh aloe vera containing flavin is likely to cause redness and allergies. Last year, I accompanied a friend to the dermatology department of the hospital. She had an acne and applied aloe vera grown at home. The next day, her face was swollen like a steamed bun. It took three days for the acne to subside.

In fact, to put it bluntly, everyone is struggling with these issues because they are still afraid of stepping on pitfalls and ruining their face. After all, natural does not mean non-irritating. It is better to do a post-auricular sensitivity test before applying it on the face and judge based on your own skin type.
