I am not here to talk you out of your sunscreen. Please keep wearing it every single day, rain or shine. That habit is doing real work. But if SPF is your entire summer skincare strategy, you are only covering half of what actually ages your skin, and the other half is the part nobody talks about.

Let me break down the chemistry. A broad-spectrum SPF blocks both UVB, the burn ray, and UVA, the ray that penetrates deeper and drives most of the free radical damage tied to photoaging. A good SPF 30 filters about 97% of UVB, and SPF 50 filters closer to 98%. Broad-spectrum formulas are designed to cover UVA as well. But 97% is not 100%, and that number comes from a lab, where a thick, even layer is applied that almost nobody actually uses. Most of us apply a fraction of that tested amount and skip the two-hour reapplication window entirely, so the real protection we get on a given day is lower than the number on the bottle.

And even flawless SPF application only addresses ultraviolet light. It does nothing for the free radicals generated by heat, pollution, and visible light, sources that have nothing to do with the sun's rays but trigger the same chain reaction of unstable, electron-hungry molecules that scavenge electrons from healthy skin cells, including the collagen and elastin that keep skin firm, triggering oxidative stress that quietly breaks down structure all summer long.

This is where antioxidants are our summertime heroes. An antioxidant works by donating an electron to stabilize a free radical before it can cause damage, without becoming unstable itself. Think of SPF as the wall, an excellent one, but not a perfect or complete one, and antioxidants as the reinforcement working the line behind it, catching what gets through and what was never UV in the first place. Neither one replaces the other, and that is really the whole point of this post. SPF and antioxidants are two different jobs done by two different tools, and summer skin needs both done well.

When people ask me what separates a good face cleansing oil from a genuinely great one, the answer lies in the oils themselves and what they do once they are on your skin. Our Free Radical Neutralizing Oil is formulated with 14 antioxidant-rich botanical and vitamin oils, including grape seed, passionfruit, and orange peel, chosen specifically for their ability to donate electrons and neutralize free radicals before they can compromise collagen and elastin. It is consistently the product our Sherak community tells us they love and reach for first, and it is often what people are searching for when they ask us what the best cleansing oil looks like on an ingredient list.

Here is how I use it every night, in this order. Cleanse first with the Free Radical Neutralizing Oil to remove what the day left behind, including sun, heat, and pollution. Follow with the Reactivation Serum, our peptide serum built on the Pentapeptide Matrix, to support the pathways that keep collagen and elastin production strong. Finish with the Barrier Shield Moisturizer, a peptide moisturizer formulated with tetrahexyldecyl ascorbate, a stable, oil-soluble form of vitamin C, so your antioxidant defense keeps working through the night while your barrier restores itself. Cleanse, serum, moisturizer, in that order, every evening. It is a simple ritual, and it is the one most summer routines are missing.

Here is the key point to remember. Your SPF has one job, and a good broad-spectrum formula, worn daily, does that job well. Give your skin the other half of the summertime coverage it needs, every night, with an antioxidant cleanse, a peptide serum, and a peptide moisturizer working together.

With grace and gratitude,

FAQ

Do I still need sunscreen if I use antioxidant skincare?

Yes. Antioxidants and SPF do different jobs. SPF blocks most incoming UV rays, antioxidants neutralize the free radicals generated by the UV that gets through, plus the free radicals caused by heat, pollution, and visible light, which SPF does not address at all. You need both, not one instead of the other.

Does SPF 30 or SPF 50 block UVA rays, or only UVB?

A broad spectrum sunscreen is formulated to block both UVA and UVB. The SPF number itself measures UVB protection specifically, SPF 30 filters about 97%, SPF 50 about 98%, while "broad spectrum" is a separate claim confirming UVA coverage. Real world protection is often lower than the tested number because most people apply less product and reapply less often than lab testing assumes.

What does a peptide serum actually do for summer skin?

A peptide serum, like our Reactivation Serum, supports the pathways that increase collagen and elastin production, which helps skin stay firm and resilient against the extra stress summer heat and sun put on the skin barrier.

What is the best cleansing oil for face in summer?

Look for a cleansing oil for face built on antioxidant-rich botanical oils rather than fragrance alone. The Free Radical Neutralizing Oil uses 14 antioxidant oils, including grape seed and passionfruit, to neutralize free radicals while it cleanses.

Can I use a cleansing oil, peptide serum, and peptide moisturizer together?

Yes, and we recommend it. Cleanse, then apply serum, then seal with moisturizer. Each step supports the one before it, which is the idea behind the full Sherak system.
