As a writer in the beauty industry, I cannot begin to explain the importance of vitamin C in a proper skin care regimen: it can hyperpigmentation, contributes to the production of skin collagen, and (we consider the most important property of this ingredient) Protect the skin from harmful free radicals. Unfortunately, the warning here is that many people are sensitive to vitamin C derived from ascorbic acid. So, does this mean that people with sensitive skin, acne-prone or even mature cannot use vitamin C? Not at all.
Vitamin C serum has various shapes and sizes, and comes from different sources, so there is little or no damage to the skin. Dr. Joshua Zeichner, Director of the Dermatology Committee and Head of Skin Beauty and Clinical Research at Mount Sinai Hospital, explained: “Vitamin C has two main forms, pure ascorbic acid and an ester form. Pure vitamin C is water-soluble. It is difficult to formulate and requires acidity. The pH value is unstable under ultraviolet light. It is usually packed in dark or opaque bottles. I think it is more irritating to the skin, so I usually use it for people who are not sensitive. On the other hand, vitamin C ester is oil-soluble Yes. I find them more useful for dry or sensitive people. Their formula is more stable and actually penetrates better into the skin.”
Dr. Zeichner continued: “If you are very sensitive, please start [applying a vitamin C serum] Every other morning-otherwise, you can apply every day. Unlike ingredients such as retinol, there is no adjustment period for vitamin C. Dr. Zeichner explained that it is more critical to combine this ingredient with sunscreen to maximize its effectiveness.
So which vitamin C serum is right for you? In advance, fully decompose the ingredients and add some products that are most suitable for your skin type.
If you often find that your patch test products are not helpful, Dr. Zeichner recommends that you use vitamin C serum derived from vitamin C esters, including “THD ascorbate, sodium ascorbate phosphate and others with words ascorbic acid inside. “
Although you may be wary of applying any sensitive and controversial content in the breakthrough, vitamin C serum can actually help you get rid of the predicament of the breakthrough. Dr. Zeichner explained: “There are data showing that vitamin C itself can help treat acne by reducing inflammation in the follicles. Vitamin C can also reduce the dark spots left behind after acne subsides.” For acne-prone skin, vitamin C is effective. The best form comes from sodium ascorbyl phosphate. However, Dr. Zeichner did explain that all forms of vitamin C are generally suitable for acne-prone skin.
Dr. Zeichner said: “If your skin is mature, you should look for vitamin C products that are used in conjunction with vitamin E. Together they can protect the skin from free radical damage, so it is useful for mature skin.” In addition, vitamin E is one A highly moisturizing ingredient, which means that while protecting the skin from free radicals, it can also plump your skin and reduce the appearance of fine lines and wrinkles.
