Swallowing a pill with a glass of water is so routine we never question whether it’s actually the most effective way to take a supplement. For glutathione and biotin — two of the most popular inner beauty nutrients — it might not be. Esther Formula’s oral dissolving strips take a different approach, and the science behind why is worth understanding.
Esther Formula is a Korean inner beauty supplement brand founded by Dr. Esther Lyuh (PhD), whose research sits at the intersection of pharmaceutical science and skin health. The brand’s flagship innovation — Oral Dissolving Strip (ODS) technology — has sold over 500 million strips worldwide and is now produced in the United States using Korea’s leading supplement innovation standards. The two flagship US-market products are the Liposomal Glutathione Direct strips and the Biotin Strips, both designed for daily inner beauty support with a 7-second ritual that requires no water, no pill-swallowing, and no schedule disruption.
What Is Esther Formula?
Esther Formula was founded on a simple but transformative idea: that the format of a supplement determines how much of it your body actually receives. Traditional pills pass through the stomach, where digestive acids and enzymes break down active ingredients before they can be absorbed. The oral dissolving strip bypasses this entirely — active ingredients absorb directly through the mucous membrane in the mouth, entering the bloodstream within seconds.
The brand is Korea’s premier oral strip supplement innovator and has expanded its flagship formulas to US production to meet global demand. Every formula is developed and safety-reviewed by Dr. Esther Lyuh, third-party tested for quality and purity, and formulated without sugar, artificial sweeteners, gluten, soy, or dairy.
The current US product lineup centres on two products covered in this review — both available at esther-mall.com with 15% off using code VIVIBLOOM1.
The Two Products at a Glance
Liposomal Glutathione Direct
90% pure liposomal glutathione · L-Cysteine · Vitamin C & E · Milk Thistle. Master antioxidant for skin radiance, liver support & cellular protection.
Biotin Strips
Fast-absorbing biotin via ODS technology. Strengthens hair and nails, promotes keratin production, supports fuller, healthier appearance.
Why Strips Beat Pills: The Science of ODS Technology
Understanding why the strip format matters requires a quick look at how traditional oral supplements are absorbed — and where the losses happen.
When you swallow a glutathione or biotin pill, the journey to your bloodstream goes: stomach → intestine → liver → bloodstream. At each stage, a portion of the active ingredient is broken down. Glutathione in particular is notoriously fragile — digestive enzymes rapidly degrade it before it can be absorbed in meaningful quantities. This is the reason why high-dose glutathione pills often show disappointing results despite impressive label numbers.
The oral mucosa (the membrane lining the inside of the mouth) is approximately 4,000 times more permeable than the skin. ODS technology exploits this: the strip adheres to the membrane, and active ingredients absorb directly into the bloodstream within seconds. Combined with liposomal encapsulation on the glutathione strips — which wraps each molecule in a phospholipid bilayer for additional protection against degradation — the bioavailability of Esther Formula’s products is significantly higher than traditional pill formats.
The 7-Second Daily Ritual
Wash your hands
Open the individual strip packet with clean, dry hands.
Place on the roof of your mouth
Grip the strip with two fingers and adhere it to the palate or inner cheek. The strip adheres on contact.
Let it dissolve
The strip dissolves within seconds. Absorption happens through the oral mucosa — no swallowing, no water required.
Continue your day
No water needed, no aftertaste (natural lemon flavor), no friction. One strip per day. Take it anywhere — at your desk, commuting, after a workout.
