FAQS

Brightening Vitamin C Serum

How do I pick the best skin brightening serum for me?

The best brightening serums contain proven actives like Vitamin C to boost radiance, Niacinamide to even out tone, and Vitamin E to help protect against oxidative stress.

Good Vitamin C brightening serums also feel lightweight, absorb easily and fit into your daily routine without irritation or buildup. Steer clear of products overloaded with fragrance or harsh alcohols, which can cause sensitivity over time.

Who can use Boost Lab's brightening serum?

We're all about inclusivity at Boost Lab, which is why our Vitamin C serum is a popular choice for a range of skin types and ages – just take a look at our reviews!  

Our Vitamin C Brightening Serum is gentle enough for daily use and ideal for anyone wanting to:

  • Revive dull, tired-looking skin
  • Tackle signs of ageing, such as dark spots

Can I use a face brightening serum every day?

Yes. Most serums for face brightening, including ours, are made for daily use. Apply once or twice a day as part of your morning or night skincare routine. Regular use helps maintain even skin tone and a healthy glow.

When should I expect to see results?

Everyone's skin is different, but you will generally notice smoother, more radiant skin within 28 days of consistent use. Over time, this Vitamin C brightening serum helps refine texture, reduce the look of dark spots and reveal a clearer, more even-toned complexion.

    Brightening Serum

    I use this in my morning routine. Applied while holidaying in Bali twice a day to help with my brown patches on my face. Helping each day not a one day miracle but after using for a few months it has helped to pre lighten the spots.

    Brightening serum

    I love the thickness of this serum, it doesn't leave my skin feeling oily at all. When used with the daily moisturiser I feel hydrated all day and love that it doesn't make me oily.

    Smooth and not stinky

    I’ve tried a few other brand vit c and they can have a strong smell that lasts on the skin. I found this one absorbs easily and no unpleasant smell. Only used for a few weeks and can see it working along with all my other skin care nicely
