There is something about the first really warm day of the year that makes me want to stand outside with my face tilted up like a houseplant. Pure instinct. Zero regrets. But if there is one thing I know after years of working with skin, it is that summer skin care is worth thinking about before the season arrives rather than after.

But it is a conversation worth having before the season arrives rather than after. Here in southern Ontario, we go from grey and cold to hot and humid almost overnight, and that shift does something to the skin that most people do not anticipate. The humidity changes how products sit and absorb. The UV index climbs faster than we remember every year. And the cumulative sun exposure that starts quietly in May is the kind that stays with us, not just this summer but for years.

As an esthetician, the thing I come back to again and again is this: protection is not a reactive conversation. The damage that shows up on skin in our forties and fifties was almost always written in our thirties and earlier. The good news is that it is genuinely preventable, and it does not require a complicated routine to do it well.

Three things. Consistent, supported, and started before the season gets away from you.

Vitamin C Serum: Your Skin’s First Line of Defence

Vitamin C is one of the most researched and clinically supported ingredients in skin care, which is a sentence I do not say lightly because I am deeply suspicious of exaggeration in this industry. But the evidence is real. Topical Vitamin C neutralizes free radicals generated by UV exposure and environmental pollution, supports collagen synthesis, and over time meaningfully improves uneven skin tone and dullness.

The key word in all of that is topical. Your moisturizer with “a hint of Vitamin C” buried in the ingredient list is not doing the same job. You need a properly formulated, stable serum applied in the morning before your SPF, at a concentration that actually reaches the skin and does something once it gets there.

The one I reach for is the Citrus & Kale Potent C+E Serum from Éminence Organic Skin Care. Combining Vitamin C with Vitamin E is not a trend, it is chemistry. Vitamin E stabilizes Vitamin C so it does not oxidize before it can work, and together they provide a level of antioxidant protection that neither delivers alone. Clean formulation, beautiful texture, and it layers under SPF without a single complaint.

Apply it every morning. That is the entire strategy.

Mineral Sunscreen: The Non-Negotiable That Actually Needs to Be Non-Negotiable

If you are only going to do one thing for your skin this summer, please let it be this one. Broad-spectrum SPF 30 or higher, applied generously, reapplied honestly. The research on daily sunscreen use and long term skin health is not a debate. It is the single most important step in any summer skin care routine.

Mineral or Chemical: Does It Actually Matter?

Mineral sunscreens use zinc oxide to physically sit on top of the skin and deflect UV rays. Chemical sunscreens absorb UV rays and convert them to heat within the skin. Here is my honest take as an esthetician: the best sunscreen is genuinely the one you will actually use every single day, and if a chemical SPF is the one that works in your routine, please keep using it. Consistent protection will always beat the perfect product sitting unused on your shelf.

That said, if you are choosing from scratch or open to switching, mineral is where I land every time. For skin that is reactive, rosacea-prone, hormonally disrupted, or post-treatment, the difference is meaningful. Less heat generated in the skin, less potential for irritation, and zinc oxide has a safety and efficacy profile that has held up across decades of research. In Ontario’s humid summers especially, a well-formulated mineral SPF also tends to wear more comfortably than people expect.

The white cast era is largely behind us now. Formulations have genuinely come a long way.

I currently love two options from Éminence, depending on what the day calls for. TheDaily Defence Tinted SPF adds a whisper of warmth and skin-evening without any real makeup effort, which on a Tuesday in June is exactly what I need. The Radiant Protection SPF Fluid is completely invisible and goes under everything without making its presence known in the way that old mineral sunscreens used to announce themselves. And I will also be reaching for TANIT this summer, a clean mineral SPF that layers beautifully and sits quietly on the skin without any fuss.

Generous application means more than you are probably using. Reapplication means yes, even at noon, especially if you are outside.

Omega Supplements: Because Skin Care Starts Before the Serum

This is the one that surprises people the most, and it is also one I feel strongly about.

Your skin barrier does not exist in isolation. It is built from the inside, supported by nutrition, sleep, stress levels, and the essential fatty acids your body cannot produce on its own. If you want to go deeper on how food directly supports your skin through summer, I wrote a whole post on eating your sunscreen and it is worth a read.

Omega 3 fatty acids specifically play a direct role in maintaining the integrity of the skin barrier, regulating moisture loss, and calming the kind of chronic low grade inflammation that shows up on the skin as redness, sensitivity, and that general look of being slightly overwhelmed by everything. Which, honestly, is a mood. But it does not have to be a skin condition.

Food first, always. Salmon, sardines, walnuts, flaxseed for those of you who have genuinely integrated flaxseed into your lives (I am working on it). But a quality supplement fills the gaps on the days when real life happens instead of a beautifully constructed omega-rich lunch, which for most of us is most days.

The supplement I recommend and use personally is Bend Beauty Renew and Protect. What sets it apart for me is that there is an actual published study behind it examining skin hydration and UV resilience specifically, not just general cardiovascular or joint health claims lifted from standard fish oil research. Skin-specific outcomes, peer-reviewed, and available to read here. You can find the study here. If you are someone who likes to look at the data before committing to something, that link is for you.

The Bottom Line on Summer Skin Care

Three things. Vitamin C in the morning. Mineral SPF applied generously and reapplied honestly. Omega support from the inside out. None of them are new discoveries. None of them require a fifteen step routine or a significant lifestyle overhaul. They just require consistency, which is still the most underrated ingredient in summer skin care and probably always will be.

Summer does not have to be something your skin recovers from in September.

With the right support going in, it can just be a season your skin actually enjoys. Same as the rest of you.
