The Science

How it works.

EPIDERMIS DERMIS HYPODERMIS Retinyl Palmitate Retinol Retinaldehyde Encapsulated Granactive

Five forms of vitamin A. Every layer of skin.

Traditional retinol converts through one pathway and irritates as a byproduct. The 5-Form Retinol blend uses HPR, bakuchiol, retinyl palmitate, retinaldehyde, and encapsulated retinol — each one targeting a different depth of skin, from epidermis to deep dermis. The result is clinical-strength resurfacing and collagen support without the flaking, redness, or purging that drives most people to quit.

Proven Benefits

Proven Benefits of 5-Form Retinol

Traditional retinol irritates because it converts through a single pathway. Dr. Ching's clinical blend of five complementary forms of vitamin A — HPR, bakuchiol, retinyl palmitate, retinaldehyde, and encapsulated retinol — delivers the smoothing, resurfacing, and collagen-supporting benefits of prescription-strength retinoids without the flaking, redness, or purging that drives most people to quit.

  • Reduces the appearance of fine lines and wrinkles
  • Smooths texture and refines pore appearance
  • Supports collagen and elastin production
  • Strengthens the skin barrier against photodamage

Questions

Frequently asked.

How is this different from traditional retinol?
Traditional retinol converts through a single pathway that produces irritation as a byproduct. Our five-form blend uses complementary vitamin A pathways that bypass the irritation mechanism while still delivering clinical-strength resurfacing and collagen support.
Will I experience purging or flaking?
96% of our users reported zero irritation in clinical testing. The five-form blend is specifically engineered to deliver retinoid benefits without the classic purge period.
How long until I see results?
Most users notice smoother texture within 2 weeks. Significant wrinkle reduction and firming typically appear between weeks 4-8 with consistent nightly use.
Can I use this with Vitamin C?
Yes. Apply Vitamin C in the morning and this retinol serum at night. The two are complementary — Vitamin C protects during the day, retinol renews overnight.
Is this safe for sensitive skin?
Yes. Dr. Ching formulated this specifically for his surgical patients with compromised skin barriers. Start 2-3 nights per week and build tolerance.
How long does one bottle last?
Using 2-3 drops nightly, one 30mL bottle lasts approximately 3-4 months.
