Description
Core 4 Protocol
Daily Tone, Texture + Radiance System
The Core 4 Protocol is a high-performance daily routine for dull, uneven, textured, or tired-looking skin. Built around C20 + FE, Advanced AX5, Y.E.S.S.®, and NutraMoist, this four-product system supports brightness, clarity, smoother-looking texture, and a more refined glow.
For patients, it creates a simple AM/PM structure that removes routine guesswork and gives each step a clear role: antioxidant support by day, corrective renewal by night, and lightweight moisture support in both routines. For practices, it offers an easy-to-recommend protocol for patients who need a more complete approach to tone, texture, radiance, discoloration, and visible skin quality.
Cleanser and SPF are routine anchors and should be used as directed. The included products are the four corrective and moisturizing steps that power the protocol: C20 + FE, Advanced AX5, Y.E.S.S.®, and NutraMoist.
Who it’s for
This protocol is ideal for skin that looks:
- Dull
- Uneven
- Textured
- Tired-looking
- Discoloration-prone
- Post-breakout marked
- Low-radiance
- Pore-visible
- Early aging-prone
- Ready for a more active routine
What it does
Supports a brighter, smoother, more even-looking complexion through a structured AM/PM routine.
- Creates a clear daily protocol for tone, texture, clarity, and radiance
- Uses C20 + FE for daytime antioxidant support and visible brightness
- Uses Advanced AX5 to target the look of dark spots, dullness, pores, and rough texture
- Uses Y.E.S.S.® to support nightly renewal, smoother texture, and visible age support
- Uses NutraMoist to moisturize while reinforcing brightness and antioxidant care
- Helps patients build a more consistent corrective skincare routine
- Gives practices an easy protocol to recommend for multi-concern skin
- Supports best visible improvements with consistent 8–12 week use
Why this protocol matters
Most patients do not need another random product. They need a routine that makes sense.
Skin that looks dull, uneven, marked, or textured usually needs more than one corrective pathway. A basic moisturizer may not be enough. A single brightening serum may not address texture. A retinol alone may not give the daytime antioxidant support patients need to build a more complete routine.
The Core 4 Protocol organizes the routine into clear daily roles. Morning care focuses on antioxidant defense, brightness, moisture, and SPF. Evening care focuses on tone correction, resurfacing, retinol-based renewal, and hydration. That structure makes the routine easier to follow and easier for providers to explain.
What’s inside
Four products. One complete tone, texture, and radiance protocol.
Each product plays a defined role in helping skin look brighter, smoother, clearer, and more refined over time.

Application
A simple AM/PM routine built for consistency.
- AM: Cleanse → C20 + FE → NutraMoist → SPF
- PM: Cleanse → Advanced AX5 → Y.E.S.S.® → NutraMoist
- Start slowly with the evening corrective steps and increase use as skin builds tolerance
- Use SPF every morning, especially when using exfoliating acids and retinol-based products
- Use as directed by your skincare provider if this protocol is part of a professional treatment plan
What to expect
Early glow first. Best visible improvements with consistent use.
Most users can expect early brightness and hydration first, followed by smoother-looking texture in 2–4 weeks. Best visible improvements in tone, radiance, clarity, and overall refinement are typically seen with consistent 8–12 week use.
Because this protocol includes active brightening, exfoliating, and retinol-based steps, tolerance matters. Start slowly, avoid layering with unnecessary aggressive actives, and use daily SPF.
