You’ve Got Questions? We’ve Got Answers

We’re *so* excited to announce that we just launched the Liz K Super First C Serum, a powerful Vitamin C serum with 13% pure Vitamin C. And it looks like you’re just as excited as we are because we’ve gotten a ton of questions about this unique product. To help you get the most out of your serum, we put together this FAQ of your most-asked questions. Read on to learn everything you ever wanted to know about this special serum.


Q: What are the benefits?

A: First C does just about everything! Vitamin C is amazing at brightening your complexion, fading acne scars — it even increases collagen production and smooths fine lines and wrinkles.

Q: How are you supposed to apply it?

A: Since it’s such a powerful serum, all you need is two drops, applied after cleansing and toning, and you’re good to go.

Q: Should I use vitamin C morning or night?

A: It’s up to you! It’s okay to use whatever time of day you want. You can even do it twice a day, it’s that gentle. But if you’re going to use it during the day, make sure to apply SPF!

Q: I heard Vitamin C is vulnerable to heat and light. How should I store it?

A: Keep it away from the sun! We like to store First C inside the box, away from direct sunlight. You could also pop it in the fridge if you like.  

Q: Can I use Retinol along with Vitamin C?

A: You can, but it’s all about timing. Retinol makes skin extra sensitive, so you don’t want to use them one after the other. Instead, use your Vitamin C in the morning and Retinol at night. If you have extra-sensitive skin, it’s best to alternate days — using it every day may cause some irritation or redness.  


Q: Is vitamin C better than AHA at smoothing skin texture?

A: Vitamin C is all about brightening your complexion and evening out your skin tone. For instance, if you have acne scars, the First C Serum would be really effective at fading them. AHA, on the other hand, exfoliates and decongests, which is better for smoothing skin.

Q: Is it good for acne-prone skin?

A: Definitely! First C is enriched with 13% pure Vitamin C, which will visibly fade those pesky red marks or dark spots that acne leaves behind, while epidermal growth factors speed up your blemish recovery process. Think of it as a two-for-one: You get brighter skin and your acne will go away even faster. Win-win!

Q: Is it OK to use on sensitive skin?

A: Yes! If you have super-sensitive skin, we suggest starting off by using it every other day so your skin can get used to it.

Q: Does it increase collagen production?

A: Research and clinical studies have shown that Vitamin C can increase collagen production. Plus, it’s an antioxidant that protects your skin from free radicals, which can cause accelerated aging.

Q: Will it make you oily?

A: Nope! In fact, Vitamin C actually helps to balance the skin.

Q: I’ve heard Vitamin C can cause skin damage from the sun. Is that true?

A: Vitamin C can make your skin more reactive to the sun, which is why it’s important to wear sunscreen on top if you choose to apply your serum in the morning. That said, Vitamin C is a potent antioxidant, which can also help your SPF work better by protecting the skin from other free radicals that can cause environmental damage.
