the light up booster is a modern-day miracle worker.

here’s the deal: we wanted to bring a vitamin C packed booster to mix with your favourite creams and serums, to skyrocket their effects.

but after doing more research on ascorbic acid in its dissolvable form for skincare, the fancy word for vitamin C, it turns out the oxidation of ascorbic acid is the same oxidation that turns copper green, apples brown, and metal to rust.

and just like you don't want to eat brown apples, you don't want oxidized vitamin C in your products, or on your skin. plus we don’t want to sell an ingredient that we know doesn’t work after two weeks (and yes, other people do!).

the alternative? sea buckthorn, the key ingredient in our super packed vitamin C booster.

want to know more?

I read a fancy paper saying that sea buckthorn is the richest source of vitamin C, with ascorbic acid content of up to 2500 mg%. that’s like, a lot.

so if you’re looking for a vitamin C booster that, I don’t know, really works, then light up is your man. packed with anti-oxidants, light up will help your skin look refreshed and lit (I had to go for the cheesy pun).


phytosqualane (olive squalane), sea buckthorn.

how to use

our boosters are like supplements for your skin. you can add them to your daily regimen as standalone products or mix them with other products to improve their performance. use light up anytime of day. mix with serums, creams or masks, and apply to face and neck. or, apply 2-3 drops directly to your skin.

allow to absorb 2-3 min before applying makeup.

Vit C serum

Absolutely love this product, you only need a small amount and it leaves your skin glowing. This is my second bottle.

It’s okay

So I love madebysunday products and I thought I’d try this booster a go and I have used it for 2 weeks and yes it brightens your skin but it made my face very greasy and it felt like the oil just sat on my skin and didn’t really do much, such a shame really considering all the other products I’ve tried have been great!

Hi Daisy,

Love a madebySUNDAY fan! The product is super concentrated so you only need to use a tiny bit as it's not diluted in water but rather squalane (vegetable sources).

Hope this helps, otherwise happy to assist you if you book in a consultation so you get the most out of your products!

Have a wonderful day,

I have been using these products for around a month now.
I started due to excellent reviews. I suffer with sun damage spots and had 3 - 4 on the tip right side of my forehead. Since using this product my sun damage spits have disappeared!!! I am over the moon thank you so much.
I'm gutted I don't have a before picture however have added an after x

Love this serum, it’s light and although it feels like an oil it sits comfortably under my moisturizer and SPF. Leaves an instant glow and has fed my skin to glow on it’s own. Highly recommend.
