You've tried the serums. The vitamin C drops. The retinol. And your skin looks... fine. Fine isn't bad. But you have a feeling fine isn't the ceiling.
Here's what most beauty routines miss: the skin is an organ. It's built from the inside — collagen synthesised in your dermis, antioxidants circulating in your bloodstream, proteins formed from what you ate for breakfast. No topical product reaches those layers. Supplements do.
This is the four-product inner beauty stack that covers the most ground, based on what the science actually supports.
The Case for Going Inside-Out
Topical skincare works on the surface. But collagen lives in the dermis. Melanin production happens in melanocytes. Antioxidant defence is a whole-body system. The skin's raw materials come from what your body has circulating, not what you apply at the sink.
That's why inner beauty supplements exist as a category. Not to replace skincare. To feed the systems that skincare can't reach.
The Four-Product Stack
1. Green Pasture L-Glutathione & Vitamin C — The Brightening Foundation
Why it works: Glutathione is the body's master antioxidant. For skin specifically, it inhibits tyrosinase, the enzyme responsible for melanin production. Less tyrosinase activity = less pigment clustering = brighter, more even tone from within. Vitamin C regenerates oxidised glutathione back to its active form, amplifying and extending its effect.
What makes this one stand out: 500mg of L-Glutathione alongside Vitamin C in a 200-capsule supply — one of the highest-strength formulations available in NZ. Currently on a Buy 2 Get 1 Free deal.

3. Go Healthy Hair Skin Nails — The Foundation Formula
Why it works: Biotin (Vitamin B7) is essential to keratin production. This formula adds zinc (wound healing, sebum regulation), silica (hair shaft strength), and B vitamins that support cell turnover. The baseline most people are mildly deficient in without knowing it. Available from $9.

4. Good Health Imaglow — The NZ Collagen Formula
Why it works: Imaglow delivers the amino acid building blocks the body uses to produce its own collagen. NZ-sourced marine collagen from clean coastal waters.
How to Stack Them
Start here: Glutathione + Vitamin C. Nothing topical does what it does. Run it for 8 weeks.
Add next: Beautiful Skin Collagen Support or Imaglow (not both at first). Commit to 10–12 weeks.
Complete the stack: Hair Skin Nails fills the micronutrient gaps — biotin, zinc, silica — that the others don't cover.
The Bottom Line
Inner beauty supplements feed your skin's actual building blocks from within. The four products above cover brightening, structural collagen support, and the nutritional foundation most beauty routines skip.
