Looking to level up your skincare routine? Adding a vitamin C serum into the mix is a great way to unlock new skincare benefits. It’s also one of the most accessible ‘actives’ (a.k.a. active ingredients that are potent enough to make visible changes to the skin over time) out there.
But what does it actually do and which one should you pick up?
What does vitamin C serum do to the face?
Vitamin C, also known as ascorbic acid, offers lots of benefits to the skin! It’s more popularly known for brightening and giving the skin a more radiant look. But it also helps reduce the appearance of hyperpigmentation or dark spots, fine lines and wrinkles.
It also promotes collagen production, keeping your skin looking supple and youthful. It protects against the sun’s harmful rays too!

Can we apply vitamin C serum everyday?
The good news is you can use one everyday! Being consistent with applying it also gives you a better chance at seeing results.
Should you use it in the morning or the evening though? While there’s no right or wrong way to use one, most dermatologists recommend incorporating it into your daytime routine. This is because it’ll work in tandem with your sunscreen in protecting your skin against sun-caused damage.
Apply your chosen serum after your cleanser (or toner) and before you moisturizer. Seal the deal with your sunscreen and you’re good to go.
Which vitamin C serum is the best?
This depends on what you need and how your skin reacts to the product, of course! But there are lots of really good options on the market to test out right now. Here are some of the best vitamin C serums you can buy in the Philippines.
1. Luxe Organix Power Glow Serum Vitamin C 20%

This serum contains not only vitamin C but also galactomyces, which has antioxidant properties that combat skin stressors. Did you know that the famed SK-II Essence is said to have galactomyces (they call it Pitera) as its star ingredient?
2. Klairs Freshly Juiced Vitamin C Serum

Got sensitive skin? Start with this serum. It has 5% vitamin C, which is powerful enough to provide skin-caring benefits but also gentle enough for those who can’t handle more potent stuff. This one’s also fragrance-free! (Pro tip: Keep this in the fridge so the serum doesn’t oxidize and lose its brightening power.)

Want to ease your way into the serum world with something that’s a bit more affordable? Try this one from Garnier. This lightweight serum promises to lighten dark spots in only three days!
