SkinCeuticals Prevent & Protect Anti-Aging Duo

$239.00

The ultimate morning ritual in one set — SkinCeuticals' most iconic vitamin C serum paired with their best-in-class tinted mineral SPF. Together, these two products deliver the gold standard in daytime skin protection: defend against free radical damage, prevent visible signs of aging, and guard against UV-induced skin damage, all in two simple steps.

This is the routine we recommend to literally everyone.

If someone asks us where to start with their skincare, this is it. C E Ferulic is the most studied, most validated antioxidant serum in medical-grade skincare — and Physical Fusion SPF 50 is the sunscreen we've seen convert the most SPF-avoiders into daily wearers. The tint is genuinely beautiful, the texture is effortless, and together they make mornings feel like a luxury ritual instead of a chore.

The value here is real too — buying both together saves you versus purchasing separately, and you get the two products that do more for long-term skin health than anything else on the market.

If you're only going to do two things for your skin every morning, make it these two.

The Prevent & Protect Duo pairs SkinCeuticals' most celebrated product — C E Ferulic — with Physical Fusion UV Defense SPF 50, their best-in-class tinted mineral sunscreen. Used together, they form the most clinically validated morning protection routine in professional skincare.

C E Ferulic is built on SkinCeuticals' patented Duke antioxidant synergy theory — a precise formulation of 15% L-ascorbic acid (vitamin C), 1% alpha tocopherol (vitamin E), and 0.5% ferulic acid that works synergistically to neutralize free radicals from UV, ozone, and pollution. It's not just protective; it actively improves the skin, reducing the appearance of fine lines, wrinkles, loss of firmness, and uneven tone with consistent use. Clinically, C E Ferulic users saw a 44.8% increase in radiance and up to 36% reduction in visible wrinkles after 20 weeks.

Physical Fusion UV Defense SPF 50 pairs with it as the ideal mineral finish — a 100% physical sunscreen with a weightless, sheer tint that adapts to all skin tones. Zinc oxide and titanium dioxide provide immediate broad-spectrum UVA/UVB protection, while iron oxides provide an additional layer of defense against visible light. Lightweight, non-greasy, and beautifully wearable on its own or under makeup.

Together, these two products don't just work side by side — C E Ferulic has been clinically shown to enhance the photoprotective effect of sunscreen fourfold when used together. That's not marketing. That's the actual science.

Step 1 — C E Ferulic
• Every morning after cleansing and toning
• Apply 4–5 drops to a dry face, neck, and chest
• Allow to absorb for 1–2 minutes before next step

Step 2 — Physical Fusion UV Defense SPF 50
• Apply generously to face, neck, and chest after your serum
• Apply 15 minutes before sun exposure
• Reapply as needed throughout the day

Pro Tip: This duo has been clinically shown to provide fourfold photoprotection compared to sunscreen alone — the serum actually amplifies your SPF. Don’t skip the C E Ferulic step.
