Let's take another look at Vitamin C.
As a dermatologist and a doctor who practices cosmetic dermatology on a daily basis, I would like to take another look at the wide-ranging beauty benefits of vitamin C. 
Vitamin C is a powerful antioxidant and an important ingredient in supporting healthy and beautiful skin.
This ingredient can be used daily not only for those who are troubled with enlarged pores, blackheads, dullness and blemishes on the face, but also for a wide range of skin concerns, including preventing wrinkles, acne and melasma.
This is the familiar Vitamin C , and it is indeed a superior Vitamin C !
I myself rely a lot on the power of Vitamin C !
I love outdoor sports, so on my days off, I almost always go outside and play sports in the sun. Of course, I take physical measures to protect myself from the sun with sunglasses and hats, but I also take vitamin C supplements and give my skin plenty of vitamin C directly with serum. I particularly use Aoharu's original vitamin C serum, which is moist but not sticky and does not interfere with other makeup, so I apply it to my face first after washing my face. By the way, I have sensitive skin and sometimes get eczema on my face. At times like that, the vitamin C serum stings, so I take a break from using the serum until the eczema heals. I hope you all enjoy skin care while listening to your own skin's voice.
Now, let me explain in detail how Vitamin C works.
1. Antioxidant protection for skin
Vitamin C neutralizes free radicals produced by external factors such as UV rays and air pollution, preventing damage to skin cells, thereby contributing to the prevention of photoaging and maintaining healthy skin.
2. Promotes collagen production
Collagen is an essential protein for maintaining skin elasticity and firmness. Vitamin C helps produce collagen and is effective in preventing and improving wrinkles and sagging skin. Regular intake and application of vitamin C can help maintain the youthful appearance of your skin.
3. Improve pigmentation
Vitamin C inhibits the production of melanin, helping to improve dark spots and dullness. Continued use will help even out skin tone, resulting in brighter, more translucent skin.
4. Promotes scar healing
Vitamin C supports wound healing and may help speed up the healing of acne, acne scars and minor wounds by promoting collagen production and acting as an antioxidant.
5.Protection from UV Damage
Vitamin C helps reduce UV damage to the skin, so when used in conjunction with a sunscreen, it can provide extra protection from UV rays.
Effective ways to take Vitamin C
Vitamin C cannot be synthesized in the body, so it must be taken from an external source. By incorporating supplements and skin care products containing vitamin C into your daily routine, you can maximize its beauty benefits. Products containing pure vitamin C ( ascorbic acid ) are particularly effective.
Important points to note
High-concentration vitamin C products may irritate the skin. When using for the first time, we recommend starting with a low-concentration product and gradually increasing the concentration while observing the skin's reaction. If the skin is injured or extremely dry, it may sting, so please take a break only in such cases. On the other hand, it is said to increase the moisture content of the stratum corneum, so if the skin is only slightly dry and does not sting, use it properly. Also, since vitamin C is sensitive to light and air, it is recommended to choose a product in a light-blocking container, close the lid tightly after use, and store it in a dark place with as constant a temperature as possible.
When purchasing cosmetics or supplements from online shops, it is important to check the ingredients and choose a reliable product. By taking in Vitamin C properly, you can aim for healthy and beautiful skin.
