Vitamin C is available in many different forms,which may cause some confusion about which vitamin C products you should use. Today we will discuss the benefits of vitaminC. Let’s see if vitamin C is good for skin. Is topical vitamin C good for skin? Hello, I am Dr. Dhananjay Chavan, CosmeticDermatologist and Hair Transplant Surgeon, Clear Skin and Hair MD, Pune. Vitamin C is an antioxidant that protectsour skin from free radical damage. These free radicals are aggravated by pollution,radiation and smoking to harm skin, making it dull and cause signs of premature ageing. Vitamin C protects your skin from cellularand tissue damage caused by free radicals. Apart from this, vitamin C prevents skin fromgetting hyperpigmented and stimulates collagen production. It is because of all these benefits that vitaminC is found in so many skin care products. Vitamin C is also known by the name ascorbicacid. It supports our immune system and helps calciumand iron absorption. Vitamin C is water soluble. Our body does not produce or store vitaminC. That is why it is necessary for us to eat or ingest vitamin C to maintain bodily functions. Eating vitamin C rich foods, fruits, and vegetableswill satisfy the daily vitamin C quota. But applying vitamin C topically has morebenefits. So let’s understand the benefits of topicalvitamin C. The first benefit is that vitamin C brightensskin. As we know, vitamin C protects the skin fromfree radical damage and prevents excess melanin production. Other than this vitamin C also plays a rolein natural skin lightening. It stimulates the production of glutathioneand vitamin E in our body which in turn stimulates the production of pheomelanin. This pigment replaces the darker pigment andmakes your skin light and bright. The second benefit is that vitamin C naturallyexfoliates the skin, bringing the lighter toned skin to the surface. The third benefit is that vitamin C improvesthe skin texture. Vitamin C helps in skin cell renewal whichevens out the skin tone. The fourth benefit is that vitamin C stimulatescollagen production which makes the skin smooth and glowing. Vitamin C is an excellent healing agent forthe skin. In fact, research indicates that vitamin Calso helps with wound healing. By stimulating collagen production, vitaminC heals and repairs the skin. The next benefit is sun protection. You know that vitamin C is an antioxidantthat protects our skin from free radical damage. It also shields our skin from UV radiationand prevents pigmentation and photoageing. Vitamin C is important for the overall healthof the body. It can be taken both topically and orally. Vitamin C can be taken orally from fruitsand vegetables. Fruits like strawberry, orange, kiwifruit,mango, grapefruit, papaya, melon, plums, grapes, apples and vegetables like red peppers , broccoli,tomato, spinach and cauliflower are excellent sources of vitamin C.But when we consume vitamin C orally, a very small percentage of it reaches our skin. In fact, research also says that topical vitaminC has more benefits. The collagen in the body reduces with age. Vitamin C is extremely useful in boostingthe collagen levels in the body. Topical vitamin C is very effective in skinrejuvenation and slowing down the ageing process. In fact topical vitamin C is 20 times moreeffective than oral ingestion. Continuous use of vitamin C for 3 days itselfshows a lot of improvement in our skin. So let us discuss the topical forms of vitaminC. Topical vitamin C is often found in moisturisersand serums. Serums are thinner and silkier in texturethan moisturisers. Moisturisers hydrate our skin, and serumspenetrate our skin and controls specific issues. Let us take a look at the benefits of vitaminC serums. Vitamin C serums have a higher concentrationof the necessary ingredients which is why they work better. Vitamin C products have a higher concentrationof vitamin C in the form of active ingredient L-Ascorbic acid. Products with vitamin C have 10-15% concentrationof L-Ascorbic acid. If you are going to use vitamin C, first startwith a lower concentration and then increase the concentration gradually. Vitamin C is available in different formsand derivatives. L-Ascorbic acid is also called LAA and thisis the most effective form of vitamin C. It is less stable in other forms which may causeirritation on the skin. If this suits your skin, it can bring aboutthe best results for your skin. It works best on normal to oily skin. Next is Magnesium Ascorbyl Phosphate whichis a water-soluble derivative. This causes less irritation to skin and isa good option for dry and sensitive skin. Next is Ascorbyl Palmitate which is a stableform and used in oil-based skincare formulas. It is less effective in other forms, but inthe stable for it is very effective in protecting the skin from free radical damage. The next form, Ascorbic Glucosamine, is effectivein reducing hyperpigmentation. It is also a water soluble derivative whichhas antioxidant and skin brightening properties. However, not a lot of research has been carriedout on this derivative. The last derivative is Sodium Ascorbyl Phosphate. This is stable and water soluble, gets easilyabsorbed into the skin and gets converted to ascorbic acid. This brightens the skin and protects it fromfree radical damage. Vitamin C is often combined with other ingredients like hyaluronic acid. Hyaluronic acid helps to hold in the moisturein the skin. This keeps the skin hydrated and makes theskin less prone to ageing. Vitamin E is also used in combination withvitamin C. Ferulic acid is also an antioxidant and helpsto keep vitamin E and C stable, protects skin from free radical damage and stimulates collagenproduction. So let us see how vitamin C is used. We will try and answer all the common andpopular questions. First question – When should we apply vitaminC? How to use vitamin C serum? If you are using vitamin C serum, you shouldapply it after your face is freshly cleansed. If you are using a vitamin C moisturiser,then apply it after the serum. Next question, how to apply vitamin C serum? Wash your hands well before applying the serumor moisturiser on your face. The next question is how much serum shouldyou use? Usually the amount of serum to be used ismentioned on the bottle, this is based on the concentration of the serum. So make sure you read all the instructionsbefore using serum. Usually, a few drops of serum are enough toapply on the whole face. It is necessary for the serum to be completelyabsorbed by the facial skin. If the serum has not been absorbed completelyor has been over absorbed, use a little lesser serum. Whenever you use a serum, remember that yourremaining skincare products should be applied only after the serum has dried. If you are applying it at night, it is necessaryto apply moisturiser after the serum. If you are applying it in the morning, thenat least apply moisturiser and sunscreen. As we said before, you should initially startwith 10-15% vitamin C serum and increase the concentration if your skin can tolerate it. Mostly, the maximum concentration used is15-20%. It is necessary to patch test any serum beforeusing, especially if you have dry and sensitive skin. Take a little serum and apply it behind yourear or on your wrist. If you do not see any unusual reaction, youcan continue using it. To see the results of any product, you willhave to wait patiently. I want to share some tips so that you getthe best results. Tip number 1:Use any skin formula regularly. Random use will not give you the desired results. Tip number 2:Do not use expired or old products. Tip number 3:Store your products well. Do not store the products in direct sunlight. L-Ascorbic acid, LAA or vitamin C may undergooxidation if directly exposed to sunlight. This is why they come only in dark glass bottles. The product has to be stored in an airtightcontainer, you should never leave the bottle open as oxygen can cause a breakdown of vitaminC serum and make it inactive. Always keep the serum in a cool, dry place. Vitamin C can degrade because of high temperatures. Tip number 4:Vitamin C serum can irritate sensitive skin. So if you have sensitive skin, you can usemagnesium ascorbyl phosphate instead of L-ascorbic acid, as this is gentler on the skin. Tip number 5:While choosing a vitamin C serum, choose one that has a pH level close to 3.5, as thiswill aid better absorption. Tip number 6:Do not combine vitamin C serums that contain L-ascorbic acid with retinol which is vitaminA and niacinamide which is vitamin B3. The pH levels of these ingredients do notmatch and do not work together. Using these in combination may cause rednesson the skin. Tip number 7:Wait at least 3 minutes before applying retinol or niacinamide with vitamin C serum. If you already have a product that has thiscombination of ingredients, don’t worry. These have been formulated systematicallyand scientifically to be used without harming your skin. Tip number 8:Pay attention to the appearance, color, smell, and consistency of your serum. Your serum should be clear or white or a lightchampagne color. Of it is cloudy, brown or dark in color, ithas become oxidised. Vitamin C serum is odourless. Tip number 9:Do not use the serums that are available in clear bottles. So as you must have understood, vitamin Cis quite effective for the health of your skin. This can be orally consumed, but your bodycannot store it and you have to regularly consume it. The vitamin C you get from your diet may notbe enough for overall skin health.
