Benefits & ingredients

2% vitamin C (ascorbyl glucoside), 1% ferulic acid and 1% organic sea buckthorn oil, with vitamin E, organic jojoba, sweet almond, avocado, rosehip and castor oils, glycerin made with organic ingredients, sodium PCA and a little hyaluronic acid. Scented with parfum. Vegan and made in the EU.

How to use

Every morning, on clean skin. Smooth one pump over face and neck and let it sink in, then Exofacial and Pep Step. SPF 30+ last, always.

Why it's different

Sunny Side Up is your morning vitamin C. 2% ascorbyl glucoside, a gentle, stable form of vitamin C, works with 1% ferulic acid and 1% sea buckthorn oil for brighter, more even-looking skin with antioxidant support for the day ahead. Jojoba, almond, avocado and rosehip oils keep it silky and soft, never sticky. One pump in the morning, then Exofacial, then SPF.

When you'll see results

Skin looks fresher and feels softer from the first morning. Most people see a brighter, more even-looking tone at 4–6 weeks of daily use, with SPF.

Frequently asked questions

You've got questions, we've got answers.

Morning or night?

Morning. Vitamin C and ferulic acid are antioxidants, so they make most sense under your SPF as you head out. At night, Beauty Sleep Bakuchiol Oil takes over.

Where does it go in my routine?

Cleanse, spritz if you like, Sunny Side Up, then Exofacial and Pep Step, then SPF 30+. Give Sunny Side Up a moment to sink in before Exofacial goes on.

Why 2%? Isn't more vitamin C better?

Not always. Pure vitamin C (ascorbic acid) at high strengths can sting and doesn't stay fresh for long once opened. We use ascorbyl glucoside, a gentler, more stable form, at 2%, with 1% ferulic acid and 1% sea buckthorn oil, so it's easy to use every single morning.

Can I use it with retinol or acids?

Yes, in different halves of the day: Sunny Side Up in the morning, and retinoids, Beauty Sleep, Fresh Start or Lunchtime Peel at night.

Do I still need SPF?

Yes. Vitamin C isn't a sunscreen. SPF 30+ goes on last, every morning.

Is it okay for sensitive skin?

It's scented, with a sweet mandarin aroma from parfum and natural essential oils. If you're fragrance-sensitive, patch-test on your jaw for 48 hours first.

I have a nut allergy. Can I use it?

It contains sweet almond oil, so please check with your doctor before using it.

Is it safe during pregnancy?

Please check with your doctor or midwife first and share the full ingredient list with them.

How long does a bottle last?

A few months at one pump each morning.

How does the guarantee work?

Use it for up to 60 days. If you don't love your skin, email support@plump.com within 60 days of delivery and we'll refund the product price, even if the bottle is empty. No need to send it back.

Reviews

Reviews summary ✦

Customers say their skin looks fresher and brighter in the morning and more even after a few weeks, without the sting they've had from stronger vitamin C serums. Many layer it under Exofacial and say it sits well under SPF and makeup. A few would prefer it unscented, and one reviewer noted the almond oil.

Vitamin C that doesn't sting

Every vitamin C I've tried made my cheeks burn. This one doesn't. I patch-tested for two days first and it's been fine every morning since.

Silky, not sticky

My old serum left a tacky film under my sunscreen. This sinks in and feels soft, and my SPF goes on smoothly over it.

Sunny Side Up in the morning, Spot On at night. My skin looks more even overall and the marks on my chin look softer. Would love a bigger bottle.

Good for oily skin, just

It has oils in it, so I was nervous. One pump is fine for my skin, but two makes me shiny by lunch. Brightness is lovely.

Under Exofacial every morning

I wanted a vitamin C that worked with The Daily Liquid Facial rather than against it. This is it. Skin looks fresh and even, makeup sits well.

My skin looks a bit brighter. The fragrance is pleasant but I prefer unscented products in the morning. Still using it up.

Read the label if you're allergic

Contains almond oil, which the page does say. I'm fine with it, but my sister has a nut allergy so she's skipping it. Lovely serum otherwise.
