The Power of Vitamin C

The Power of Vitamin C

Hello, beauties! It’s another Friday and time for some more skincare talk! On today’s agenda is one of the most proven, reliable, and versatile ingredients in modern skincare—vitamin C!

What can vitamin C do for skin?

Unlike many trendy but unsubstantiated skincare ingredients, vitamin C’s positive effects on skin are well known and have been researched for some time. The three main benefits of vitamin C in skincare are:

  • Photoprotection: Vitamin C is a powerful antioxidant, which means that it prevents free radicals, which are destructive at a cellular level, from damaging skin. Topically applied vitamin C has been shown to protect skin from UV damage, making it a powerful ally against sun-induced skin aging! Vitamin C is not a substitute for sunscreen but is an excellent booster to your daily sunscreen’s protection. (Source:
  • Collagen synthesis: Vitamin C doesn’t just protect skin from premature wrinkling and sagging caused by sun damage—it can actually reverse at least some of that wrinkling and sagging! It does so by stimulating increased production of healthy collagen in skin. Collagen is the support system for skin. In a youthful, healthy complexion, collagen keeps skin firm and smooth. Collagen breaks down with age and sun damage, and our skin is less able to produce healthy collagen as we age. The support that vitamin C provides can minimize the damage, smoothing out fine lines and reducing wrinkles. (Source:
  • Reduction of excess pigmentation: Vitamin C is also important for the treatment of dark spots and excess pigmentation caused by things like sun exposure and acne scars. Vitamin C reduces existing hyperpigmentation over time. It also helps block the production of more melanin, minimizing the appearance of new dark spots in the future. Finally, vitamin C helps prevent existing melanin from oxidizing in skin, also helping to minimize the appearance of hyperpigmentation and sunspots. (Source:

Vitamin C warnings

So far, so good, right? Vitamin C’s status as a skincare superstar is pretty solid! But that doesn’t mean that any source of vitamin C will do. Here are a few things to keep in mind as you look for ways to get more vitamin C into your skin’s diet:

  • Eating more vitamin C won’t help your skin much, so upping your orange intake (though very healthy for the rest of you!) isn’t going to replace a solid vitamin C product. Our bodies tend to prioritize pretty much every other organ system before skin, so your skin won’t receive much of any vitamin C you consume. The fact that our bodies don’t store unused vitamin C also works against efforts to improve skin by eating more fruits and veggies.
  • Speaking of ingesting vitamin C, using the contents of vitamin C dietary supplements as skincare isn’t a good idea, either! In order to be properly absorbed by skin (rather than our digestive systems), vitamin C needs to be correctly formulated as a skincare product. Breaking open a vitamin C capsule and putting it on your face is more likely to cause irritation and breakouts than to provide skin benefits.
  • Finally, be very wary of skincare tips that suggest putting orange, lemon, or any other citrus juices directly on your skin. Doing so can lead to severe skin reactions caused by sunlight. It’s dangerous and unnecessary!
