Almost everyone can benefit from using this product. It fights UV damage, reduces the appearance of pigmentation and boosts collagen production for firm, smooth, glowing skin. Formulated with 15% antioxidant-rich Vitamin C Complex to combat free radicals (molecules with unpaired electrons known to damage skin cells) and NAD+ (an essential-for-life molecule needed for cellular energy, cell function and repair) boosting technology to protect and target the signs of ageing and reinforce the skin barrier. Think of this formula as a way to future-proof your skin.

Use one pump and apply to skin using the 13 Dot Technique ™ for full, even coverage. Add three dots to the forehead, three on each cheek, two on the nose and two on the chin, then massage in.

We recommend using Flawless Vitamin C NAD+ Serum in the morning to harness its free radical-fighting powers during the daytime, when our skin is more exposed to pollutants. Apply after cleansing skin and before applying Flawless Brightly Serum and your chosen Dr Sam’s moisturiser. Finish with SPF to further protect against UV damage.

Flawless Brightly 10% Azelaic Acid Serum is powered by 2% vitamin C alongside 10% azelaic acid, 5% niacinamide and 1% bakuchiol. Its key benefits are reducing redness, clearing pores, and brightening skin. Dr Sam formulated Flawless Vitamin C NAD+ Serum to work in partnership with Flawless Brightly 10% Azelaic Acid Serum by adding in additional antioxidant power to tackle the signs of ageing and by boosting NAD+, your Brightly Serum works even harder because the cells are energised. The result - healthy, vibrant skin others can’t help but notice.

Yes, all skin types are able to use Flawless Vitamin C NAD+ Serum. If your skin tends to be on the sensitive side, use alongside Flawless Moisturiser Intense to start with, which also contains barrier-building NAD+ technology. If your skin is very sensitive, use moisturiser first (“buffering”), then layer serum on top on alternate days for the first few weeks while your skin adjusts, then try using it daily. After that, you can start to apply serum directly onto your skin.

Yes, all of Dr Sam’s products are cruelty-free and Leaping Bunny approved.

We would recommend using Flawless Vitamin C NAD+ Serum on post-blemish skin, once the ‘angry’ stage of your breakouts has started to calm down - breakouts should be less frequent and last less time.

Vitamin C helps tackle the breakout aftermath, to help diminish the dark marks or acne scars, when it can get to work on reducing redness and smoothing skin texture. For active blemishes, try Flawless Neutralising Gel as your first line of defence against breakouts.
