Having five active serums doesn't mean you need to use all five every day. The key is knowing which ingredients complement each other, when to use them, and how to adjust your routine as your skin's needs change.
We recommend Vitamin C and Probiotic Enzymes in the morning, Retinol and CoQ10 at night, and Green Tea Resveratrol whenever your skin needs extra calming and barrier support. Here's how to build a complete routine with Exponent's five fresh-activated serums.
Our five fresh-activated serums were developed to address a range of skin concerns, from premature aging and discoloration to clogged pores and sensitivity. We recommend Vitamin C and Probiotic Enzymes in the morning, Retinol and CoQ10 at night, and Green Tea Resveratrol whenever your skin needs extra calming and barrier support. Here's how to make the most of each formula in your daily routine.
Your Skincare Routine at a Glance
AS NEEDED / RESET
Green Tea + Resveratrol + Cica for sensitive-skin days and barrier support.
- AM: Brightening Boost Vitamin C + Clear Comeback Probiotic Enzyme for antioxidant support, radiance, pores, and texture.
- PM: Time Rewind Retinol + Firming Filter CoQ10 for cell turnover, fine lines, and firmness.
- As needed: Calm Revival Green Tea Resveratrol for visible redness, sensitivity, and barrier support.
You don't need to use all five every day. Think of this as a guide to choosing the right treatment for your skin, rather than a checklist to complete.
The Morning Routine: Brighten and Protect
Your daytime routine should focus on protecting skin from environmental stressors while addressing concerns like dullness and uneven texture. For this, we recommend pairing Vitamin C with Probiotic Enzymes.
Brightening Boost Vitamin C: Your Daily Antioxidant
There's a reason Vitamin C is a staple in so many dermatologist-recommended routines. As a powerful antioxidant, it helps neutralize free radicals generated by UV exposure and environmental pollution, which contribute to premature skin aging.
Beyond its protective benefits, Vitamin C supports collagen production and helps visibly improve discoloration and uneven skin tone.
Our Brightening Boost Vitamin C Active Serum contains 10% pure L-Ascorbic Acid, preserved in powder form until the moment of activation. This is especially important for Vitamin C, an inherently unstable ingredient that begins losing potency when exposed to water, air, and light.
By activating it fresh, you're getting a precise dose of pure Vitamin C at its most potent, rather than relying on a pre-mixed formula that may have oxidized over time.
Clear Comeback Probiotic Enzyme: For Clearer Pores and Smoother Texture
If Vitamin C takes care of your skin tone, Clear Comeback Probiotic Enzyme Active Serum addresses what's happening on the surface.
The formula combines exfoliating enzymes that help break down dead skin cells clogging your pores with probiotics that support the skin's microbiome and barrier health.
Unlike exfoliating treatments that can leave skin feeling stripped or dry, Clear Comeback is designed to refine texture while maintaining hydration. In clinical testing, the formula demonstrated improvements in blemishes, blackheads, and pore size in just 1–2 weeks.
Paired with Vitamin C, it helps address both uneven tone and texture for a clearer, more radiant complexion.
How to use them: After cleansing, activate and apply Brightening Boost Vitamin C, followed by Clear Comeback Probiotic Enzyme. Allow the first serum to absorb before applying the next. Finish with moisturizer and broad-spectrum SPF 30 or higher.
The Evening Routine: Renew and Firm
Nighttime is when we recommend bringing out two of our most powerful anti-aging ingredients: Retinol and CoQ10.
While Retinol encourages skin renewal, CoQ10 helps support cellular energy and combat oxidative stress. Their complementary benefits make them a particularly effective pairing for targeting visible signs of aging.
Time Rewind Retinol: The Gold Standard for Skin Renewal
Retinol is one of the most extensively studied ingredients in skincare, and for good reason. It increases cell turnover and supports collagen production, helping improve the appearance of fine lines, wrinkles, and uneven texture over time.
The challenge with Retinol is that it's both notoriously unstable and potentially irritating, especially for sensitive skin.
Time Rewind Retinol Active Serum contains 0.25% pure Retinol, protected in powder form until activation. The formula was developed with sensitive skin in mind and clinically tested for improvements in fine lines, wrinkles, and texture.
We recommend incorporating Retinol into your evening routine, starting with a few nights per week if you're new to the ingredient and gradually increasing frequency as your skin adjusts.
Firming Filter CoQ10: A Boost for Skin Firmness
Coenzyme Q10, or CoQ10, is an antioxidant naturally found in our bodies that plays an essential role in cellular energy production. Our skin's CoQ10 levels decline as we age, making it a useful ingredient to consider for a firming routine.
Firming Filter CoQ10 Active Serum delivers 0.5% CoQ10 per dose to help improve skin firmness, reduce the appearance of fine lines, and restore a more youthful-looking complexion.
It's also a favorite among makeup artists for its ability to leave skin looking smoother and more radiant.
We especially like pairing CoQ10 with Retinol at night. While Retinol targets cell turnover, CoQ10 provides antioxidant support and helps address the loss of firmness associated with aging.
How to use them: After cleansing, activate and apply Time Rewind Retinol, followed by Firming Filter CoQ10. Finish with moisturizer. If you're easing into Retinol, CoQ10 can also be used on its own on the evenings you're taking a break.
When Your Skin Needs a Reset: Calm Revival
Even with a consistent routine, skin doesn't always behave predictably. Seasonal changes, environmental stress, or overdoing active ingredients can leave it feeling more sensitive than usual.
When that happens, the best approach is often to simplify your routine rather than introduce more treatments.
Calm Revival Green Tea + Resveratrol: For Sensitivity and Barrier Support
Calm Revival Green Tea Resveratrol Active Serum was developed specifically for skin that's prone to redness, irritation, and sensitivity.
Its formula combines Green Tea EGCG, a potent antioxidant known for its soothing properties, with Resveratrol, which provides anti-aging benefits while remaining gentle on reactive skin. Cica rounds out the formula by helping calm irritation and support barrier repair.
What makes Calm Revival particularly versatile is that it addresses signs of aging without relying on more intensive actives like Retinol.
We recommend keeping it on hand for days when your skin feels reactive or its barrier needs extra attention. It can be used morning or night, either as part of your regular routine or in place of stronger treatments while your skin recovers.
Think of it as the serum you reach for when your skin tells you it needs a break.
Why Fresh Activation Matters
Choosing the right active ingredients is only part of the equation. Many powerful skincare ingredients, particularly Vitamin C and Retinol, are inherently unstable and can begin losing potency in conventional water-based formulas long before you've finished the bottle.
Exponent's patented Self-Activated Skincare System keeps concentrated active ingredients in powder form until the moment of use. Each powder is freshly activated with our Quadruple Hyaluronic Acid Hydrator, delivering a precise dose of potent actives alongside multi-depth hydration.
With one shared hydrator and five interchangeable Active Powders, it's easy to customize your routine as your skin's needs change.

The Exponent Anthology brings together all five of our clinically tested Active Powders and the Quadruple Hyaluronic Acid Hydrator, so you can create a routine that's as comprehensive or as simple as your skin needs it to be.

FAQ
Which Exponent serums should I use in the morning? We recommend Brightening Boost Vitamin C first, followed by Clear Comeback Probiotic Enzyme. Apply each freshly activated serum separately after cleansing, then finish with moisturizer and broad-spectrum SPF 30 or higher.
Which Exponent serums should I use at night? Our suggested evening pairing is Time Rewind Retinol followed by Firming Filter CoQ10. Apply them after cleansing and before moisturizer. If you are new to retinol, begin with a few nights per week and use CoQ10 alone on other nights.
Can I use vitamin C and retinol in the same skincare routine? Yes, you can include both in your overall routine. We recommend using Vitamin C in the morning and Retinol at night to simplify layering and reduce the risk of irritation.
Can I use vitamin C and probiotic enzymes together? Exponent recommends Brightening Boost Vitamin C and Clear Comeback Probiotic Enzyme as a morning pairing. Activate and apply them separately. If your skin is sensitive or you are introducing new actives, start gradually and adjust based on tolerance.
When should I use Calm Revival Green Tea Resveratrol? Use Calm Revival in the morning or evening when skin feels sensitive, looks red, or needs extra barrier support. During a flare-up, simplify your routine and use it in place of stronger treatments until your skin feels comfortable.
Do I need to use all five serums every day? No. The five serums cover different skin concerns, but they are not meant to be used all at once. Choose a morning and evening routine based on your skin’s needs, and keep Calm Revival available for sensitive-skin days.
How do Exponent’s fresh-activated serums work? Each Exponent Active Powder is kept separate from the Quadruple Hyaluronic Acid Hydrator until use. Dispense and mix them just before application to make a freshly activated serum, then apply it as part of your usual skincare routine.
