What to expect
A Routine, Not a Miracle
Skin starts to feel more comfortable and hydrated as the formula settles into your routine.
Texture feels smoother, and skin feels more resilient day to day.
Continued use supports firmness and visible bounce over time.

You're not imagining it
Your Skin Didn't Just Age. Something Changed.
"How fast everything changed after menopause because nobody warned me... The texture got rough almost overnight." A real comment surfaced during our audience research on this exact experience, not a Kreizi customer review.
- Texture that feels rougher, almost overnight
- Firmness that seems to disappear faster than it used to
- A "crepey" feel along the neck that wasn't there before
The real mechanism
The Estrogen Crash
Skin change in menopause isn't a slow fade. It's driven by a specific hormonal shift, and understanding it is the first step to working with your skin instead of against it.
Estrogen level, perimenopause through menopause: illustrative chart, not measured clinical data.
Estrogen declines
Estrogen levels drop sharply during perimenopause and menopause.
Collagen loss accelerates
Collagen production slows quickly once estrogen drops, not gradually.
Skin barrier weakens
A weaker barrier means less moisture retention and more sensitivity.
Texture & firmness change suddenly
This is the "cliff" moment so many women describe.
Two of these four breakdowns, collagen loss and a weakening barrier, are exactly what a signal peptide called Heptapeptide-7 is formulated to address: prompting fibroblasts, the cells that build collagen, into more activity, while the rest of the formula works to rebuild the barrier's ability to hold moisture.
This is exactly where Collagen Peptide Treatment steps in.
The solution
Formulated for This Exact Moment
- Supports the skin's natural collagen production
- Strengthens the moisture barrier
- Restores bounce and resilience to compromised skin
- Helps skin retain moisture through the day
Complete the Routine layers 3 steps in a specific order, morning and night. Each one is built to work on top of the one before it, not compete with it.
Step 1 · Collagen Peptide Treatment
Apply first to clean face and neck, AM & PM. A barrier that's still under-hydrated doesn't hold up as well to what's layered on top of it, so this step goes on first.
Step 2 · Collagen Booster
Layer over Step 1 once the barrier has something to work with. A concentrated texture, used in small amounts, carrying the formula's collagen-derived peptide.
Step 3 · Vita-C Brightening Booster
Apply last, in the morning, before SPF. Tone evenness is the least time-sensitive of the three needs, and this is when a stabilized Vitamin C does its antioxidant job best.
Tip: layer Step 1 under your regular moisturizer for extra comfort in dry climates.
Despite the name, this treatment doesn't rely on collagen molecules sitting on top of skin. Native collagen is roughly 300,000 daltons, far too large to meaningfully absorb through skin; the practical ceiling dermatology research points to is closer to 500 daltons.
Heptapeptide-7
The ingredient doing the most work here: a short signal peptide, not collagen itself. In lab and ex-vivo research, not a clinical trial on this specific cream, it's been shown to prompt fibroblasts, the cells that build collagen and elastin, into more activity.
Barrier & comfort support
Niacinamide, a stabilized Vitamin C (Tetrahexyldecyl Ascorbate), the antioxidant dipeptide carnosine, shea butter, and calming plant extracts (magnolia bark, witch hazel, rosemary, sage, thyme) round out the formula.
- Fragrance-free
- No synthetic dye

If you only do one step
Skip the Peptide Treatment
Booster and Vita-C still go on, but onto a barrier that's still under-hydrated. Both have less to work with.
Skip the Booster
Hydration and tone can both still improve. The only step carrying a collagen-derived peptide is the one left out.
Skip the Vita-C
The least costly of the three to skip. Hydration and firmness both hold; tone evenness is what's left on the table.

Questions
FAQ
Yes. Collagen Peptide Treatment is formulated without added fragrance.
The formula is fragrance-free and dye-free, and the Vita-C Brightening Booster uses a stabilized Vitamin C (Tetrahexyldecyl Ascorbate) instead of standard L-Ascorbic Acid, which is gentler on a reactive barrier. As with any new product, we recommend patch-testing on a small area first, especially if your skin is easily irritated.
Most people notice their skin feeling more comfortable within the first 1-2 weeks, with texture and firmness changes building over 4-8 weeks of consistent use.
Apply Collagen Peptide Treatment first, since a hydrated barrier holds up better to what's layered on top of it. Follow with Collagen Booster, then Vita-C Brightening Booster last, before SPF. Follow with your regular moisturizer.
