From fading hyperpigmentation<\/a> to repairing free radical damage, there are countless benefits of incorporating vitamin C serums<\/a> into your skin care routine.<\/p>\n

But with so many products claiming they deliver all the benefits of vitamin C, how do you go about choosing the right one for you? Turns out, factors like bio-availability and oil versus water-solubility<\/a> are important things to consider.<\/p>\n

Celebrity esthetician\u00a0Ren\u00e9e Rouleau<\/a>\u00a0breaks down everything you need to know below.<\/p>\n

Choose an oil-soluble form of vitamin C<\/strong>
\nCheck the ingredient label to see the form of vitamin C used. While pure, water-soluble forms of vitamin C, like ascorbic acid or L-ascorbic acid, are highly bio-available, they are also unstable and acidic, which risks irritation, skin barrier damage, and inflammation on sensitive skin. \u201cYou\u2019re much better off choosing a vitamin C serum with modern ingredients that are known for being stable and less acidic on the skin,\u201d Rouleau shares. \u201cOil-soluble forms of vitamin C are generally retained longer in the epidermal layers, providing prolonged benefits while [remaining] stable [and] without causing sensitivity.\u201d Rouleau recommends the Ren\u00e9e Rouleau Vitamin C&E Treatment<\/a>, which contains forms of vitamin C like tetrahexyldecyl ascorbate (THD ascorbate), ascorbyl methylsilanol pectinate, magnesium ascorbyl phosphate, and sodium ascorbyl phosphate.<\/p>\n

Ascorbic acid and L-ascorbic acid can make blackheads worse<\/strong>
\nThe right vitamin C serum should bring a glow and a more even skin tone in weeks. If you develop blackheads that worsen with time, an unstable form of vitamin C could be the culprit. \u201cAscorbic acid and L-ascorbic acid are known to oxidize quickly on the skin in the presence of light and air,\u201d Rouleau states. \u201cThis can cause unwanted side effects like more noticeable blackheads.\u201d<\/p>\n

Formulas with multiple active ingredients offer more comprehensive protection<\/strong>
\n\u201cYou will want to look for a formula that uses a variety of skin-protecting active ingredients,\u201d Rouleau advises. \u201cA good rule of thumb is to look at the key ingredients that are being promoted.\u201d For example, combining vitamin C with vitamin E and ferulic acid (like in the\u00a0Peter Thomas Roth Potent-C Vitamin C Power Serum<\/a>) are two favorites of Fatma Shaheen, founder of Skin Design London<\/a>. Rouleau also notes that its benefits are particularly noticeable for retinol-users.<\/p>\n

Packaging should be opaque and air-tight<\/strong>
\n\u201cAir and light are the worst enemies for a vitamin C product,\u201d Rouleau warns. \u201cAvoid vitamin C serums where you can see the formula through the container [or] that uses dropper bottles or a dip-tube pump [because] this allows air to enter.\u201d<\/p>\n

Toss it if it changes to a copper brown color<\/strong>
\nIf your serum begins to turn brown, Rouleau warns that this means it’s an unstable form of vitamin C. \u201cOnce the product has started to turn a light brown or copper color, you are definitely not getting the full benefit,\u201d she warns.<\/p>\n

Retinol-users must choose their vitamin C carefully<\/strong>
\nStability is the most important factor when pairing a vitamin C with a retinol. \u201cChoose a formula that offers long-lasting activity in the skin with maximum stability. A product that relies exclusively on ascorbic acid or L-ascorbic acid will not deliver the full benefits if the product can\u2019t hold up,\u201d says Rouleau.<\/p>\n
