Vitamin C and SPF
The morning pairing your skin has been asking for.
If there are two things we talk about more than anything else at The Follicle Spa, they are vitamin C and SPF.
Not because they are having a moment. Not because they are new. Because after decades of caring for skin in Burlington, these two ingredients continue to be among the most well-supported, most consistently effective choices a person can make for their skin. The science behind them is compelling. The results our clients experience over time are real. And as the days grow longer and the sun grows stronger, May is exactly the right time to make sure both are a part of your morning.
This is what each one does on its own, and what they are capable of when they work together.
What vitamin C is doing for your skin
Vitamin C is an antioxidant. That word gets used a lot in skincare, and it is worth understanding what it actually means for your skin.
Every day, your skin is exposed to UV radiation, pollution, and environmental stress. These exposures generate something called free radicals: unstable molecules that cause oxidative stress at the cellular level. Over time, unaddressed oxidative stress contributes to dullness, uneven skin tone, changes in texture, and collagen breakdown. It is cumulative, and quiet, and it is happening whether or not you are paying attention to it.
Vitamin C, applied to your skin each morning, works by neutralizing those free radicals before they can cause lasting damage. It is not a corrective ingredient in the reactive sense. It is a protective one. And the benefits accumulate steadily over months and years of consistent use.
But vitamin C does something else that makes it genuinely essential.
Your skin cannot produce collagen without it.
Collagen synthesis, the process by which your skin builds and maintains its structural protein, requires vitamin C as a necessary partner. Without adequate vitamin C, that process is compromised. With consistent daily use, you actively support your skin’s ability to stay firm, resilient, and healthy over time. This is why we recommend it so often, and why it belongs at the beginning of a thoughtful morning routine.
What SPF is doing for your skin
If vitamin C works at the cellular level, SPF works at the barrier level. And both are necessary.
Sunscreen creates a protective layer between your skin and UV radiation. UV is the single most significant external factor in collagen degradation. Daily exposure, even on overcast days, even incidentally through a window, breaks down existing collagen and disrupts your skin’s ability to produce new collagen. It is also the primary driver of uneven skin tone and the kind of cumulative texture changes that have very little to do with how old you are and everything to do with how well your skin has been protected.
May matters here. The days are longer now. The sun is higher in the sky. Many of us are spending more time outdoors, in cars, and near windows, and our skin is absorbing more UV exposure than it did in January, often without us noticing.
Daily SPF is not a summer habit. It is a year-round one, and spring is the season when it becomes especially important to revisit.
SPF protects everything you are working toward. Every serum you apply, every professional treatment you invest in, every good decision you make for your skin. Without it, UV exposure quietly undermines much of that work. With it, your skin keeps what it has earned.
The dream team: why vitamin C and SPF belong together
Used together, these two ingredients do something that neither one can fully accomplish on its own.
Think of it this way. SPF creates a barrier, but no sunscreen absorbs or reflects 100% of UV radiation. Some gets through. Vitamin C is there to address what does, neutralizing the free radicals generated by that exposure at the cellular level before they compound the damage.
At the same time, vitamin C benefits from the protection SPF provides. UV radiation can destabilize topical vitamin C over the course of a day. SPF maintains the conditions that allow vitamin C to remain effective from morning until evening.
Each one makes the other more powerful. SPF reduces the burden that vitamin C has to manage. Vitamin C addresses the damage that SPF cannot fully prevent. Together, they protect your collagen from two directions at once: blocking the primary cause of collagen breakdown at the surface, and supporting collagen synthesis from within.
The routine that follows from this is beautifully simple. Cleanse. Vitamin C serum. Allow it a moment to absorb. Moisturize. SPF over top. Four steps. Five minutes. The most reliable foundation you can give your skin every single morning.
Making this work for your skin
Consistency is where the real results live with both of these ingredients. One morning will not shift your skin. Six months of this routine will, and the changes will build quietly in the best possible way.
The products you choose matter, too. Not all vitamin C formulations are created equally. Concentration, stability, and the presence of supporting ingredients all influence how effective a serum will be for your specific skin. The same is true of SPF. A formula that sits beautifully on your skin is one you will actually use every day, and that is ultimately what determines results.
If you are not sure where to begin, or if you have been using vitamin C and SPF for a while and want to know whether you are getting the most from what you have, our team would love to help. This is exactly the kind of conversation we have every day.
We are also featuring our Vitamin C Facial this month, for anyone curious about what professional-grade vitamin C can do beyond what at-home products offer. A professional treatment takes the ingredient to a whole new level. The formulations, the preparation of your skin, and the technique all work together to deliver results that your daily serum builds toward but cannot fully replicate on its own.
Your skin is worth a few good decisions every morning. These two are a very good place to start.
Always learning, always glowing,
