In general, dermatology does not encourage to press the affected area, because improper handling will make the inflammation problem intensifying, and will lead to deeper inflammation of hair follicles, form acne.
Generally speaking, acne treatment can be divided into two major categories of oral and topical: oral antibiotics can prevent the growth of bacteria in the hair follicles which cause inflammation, thereby reducing acne; some oral vitamin A will control skin cell renew and reduce oil secretion, but will also comes with dry skin side effects, these patients can choose some with moisturizing auxiliary treatment products. Tretinoin (Vitamin A series) can effectively get rid of acne, it is reported that: tretinoin (Vitamin A series) remove acne, cosmetic effect is significantly, from remove acne, smooth fine lines, dilute the stain to narrow pores, almost almighty. Because of these drugs are irritating, many patients often abandon the use. The researchers point out, learn how to proper use tretinoin can reduce the side effects.
Compared to prescription products, the efficacy of non-prescription tretinoin product is weak, the onset time is longer, but to skin is relatively mild, and the price is relatively low. Therefore, the tretinoin manufacturer recommend that sensitive skin and first time users should be selected concentration of 0.1% of non-prescription tretinoin formulations retinol, it can be slowly converted to the active ingredient - tretinoin, so that its irritating to the skin will relatively small.
If use three months, the skin has not improved, we can consider switching to more effective prescription preparations. In this case, the non-prescription products had been make the skin gradually adapt to, so that even change to the preparations at this time, the side effects produced by latter will likely be significantly reduced. Due to tretinoin drugs will in some extents dry the skin. Therefore, choose to start using in summer when the air humidity is relatively large, it is a more scientific program.
What should be noted that during application period of retinoic acid, should be suspended for the depth of facial care. Because dry skin is more prone to having burning sensation, it is necessary to consider continuing facial cares after the stimulation symptoms of tretinoin disappeared completely. Moreover, some facial products, including scrub cream, exfoliating products, containing alcoholic toner, containing drugs cleanser and cosmetics, may react to tretinoin, should avoid using at the same time.
Cosmetic raw material suppliers advise that when the first time use tretinoin, take the size of the beans amount to try, but should avoid applied in lips, eyelids, and other sensitive areas. Retinoic acid has obvious teratogenic effects, even if apply very small doses, or a very short time, it may cause fetal severe brain and heart defects, mental retardation, therefore, during the treatment and stopping medicate 30 days after should strict contraception. Due to retinoic acid can make the surface dead skin shedding, which is equivalent to remove the natural protection of skin against UV layer. User can topical use the antioxidant products which can reduce inflammation, such as green tea essence. Mixed with oats and fresh milk into a paste, applied to the face for 10-15 minutes, first wash with warm water, then the cold water, it also can remove steatorrhea material, make the skin smooth and delicate.

Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
