Supplements

Inner Beauty: Supporting your beauty from within

Aesthetic medicine has its limits with external approaches alone. The foundation of beauty—collagen synthesis in the skin, melanin metabolism, antioxidative defense, and intestinal environment—is all determined by nutritional status at the cellular level. Under physician supervision, Zetith Beauty Clinic's supplement program carefully selects scientifically-backed ingredients and provides inner care that maximizes treatment effectiveness.

Collagen Peptide: Supporting skin firmness and elasticity from within

Collagen is a protein that comprises approximately 70% of the dermis and is responsible for skin firmness, elasticity, and hydration. As we age, collagen production declines, leading to sagging skin and wrinkles. A randomized controlled trial published in Nutrients in 2019 (Bolke et al., DOI: 10.3390/nu11102494) reported that women who consumed a drink supplement containing 2.5g of collagen peptide showed significant improvements in skin moisture, elasticity, roughness, and density after 12 weeks. Additionally, a 2022 review in Dermatology Practical & Conceptual (DOI: 10.5826/dpc.1201a18) demonstrated that oral collagen is effective in delaying age-related skin changes.

Vitamin C: Essential for collagen synthesis and skin brightening

Vitamin C is essential as a coenzyme for collagen-synthesizing enzymes (prolyl hydroxylase and lysyl hydroxylase) and is also an antioxidant that inhibits melanin production. Since the body cannot synthesize it, continuous supplementation through diet and supplements is important. Our clinic provides high-concentration vitamin C supplements (2,000-3,000mg per packet), and combined use with infusion therapy can produce additional synergistic effects. Saviluna (containing vitamin C, hydrogen, and blood orange extract) supports prevention of UV damage and post-inflammatory hyperpigmentation by eliminating reactive oxygen species.

NMN & CoQ10: Cellular energy and anti-aging

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme involved in cellular energy metabolism and DNA repair, and its levels in the body decline with age. NMN (β-nicotinamide mononucleotide) is a precursor to NAD+ and efficiently restores intracellular NAD+ concentration. Zetith NMN10000+, formulated under physician supervision, contains NMN (domestically manufactured), CoQ10, collagen peptide (fish-derived), resveratrol, and vitamin B12. This multi-faceted approach supports youthful cellular function. Coenzyme Q10 is essential for ATP production in the electron transport chain of mitochondria in cellular tissue and, as a potent lipid-soluble antioxidant, reduces oxidative stress in skin cells.

Intestinal Health: The foundation of beautiful skin and immunity

The intestine is also known as the "second brain," with approximately 70% of immune cells concentrated there. When the balance of the intestinal microbiota becomes disrupted (intestinal dysbiosis), it can lead to skin irritation, allergies, and chronic inflammation. Our clinic offers a comprehensive lineup to support intestinal health, including probiotics such as butyric acid bacteria (Miyai BM), plant-derived lactic acid bacteria, bifidobacteria, and lactoferrin in D-Lact, glutajennics (containing glutamine, licorice, and aloe vera) that protect the intestinal mucosa, and digestive enzyme supplements such as Digestive Enzymes.

Minerals, Vitamin D, and Omega-3: Nutrients commonly lacking in modern diets

Zinc is involved in over 300 enzyme reactions and supports collagen synthesis, immune function, and hair keratin formation. Zinc picolinate (Zinc30) is known as the form with the highest absorption rate. Magnesium serves as a coenzyme in over 300 biochemical reactions including muscle contraction, nerve transmission, and hormone secretion. Magnesium glycinate is a form with minimal burden on the digestive tract and high absorption rate. Vitamin D is involved in intestinal mucosa protection, immune regulation, anti-allergy effects, and bone density maintenance. Our clinic provides vitamin D3 supplements at 1,000IU-4,000IU. Omega-3 (DHA, EPA, and DPA) has anti-inflammatory effects and contributes to inflammation recovery after treatment and strengthening of skin barrier function.

Synergistic effects through combination with treatments

For those undergoing cosmetic surgery, laser, and injectable procedures, concurrent use of supplements before and after treatment promotes recovery. High-concentration vitamin C accelerates collagen resynthesis and prevents post-inflammatory hyperpigmentation, zinc promotes wound healing, and omega-3 calms inflammation. Following consultation with your attending physician, we will propose an optimal program tailored to your specific treatment type and timing.
