Spa Treatment — Professional Japanese Skincare from Japan Gals | Tsujimoto Market

About Spa Treatment (スパトリートメント)

Spa Treatment is a premium Japanese skincare brand developed by Wave Corporation, one of Japan's leading cosmetics manufacturers. The brand was born from a deep respect for the Japanese tradition of onsen (hot spring) bathing and its legendary skin benefits. Spa Treatment products harness the restorative power of natural Japanese ingredients — particularly hyaluronic acid, collagen, and mineral-rich components inspired by Japan's healing thermal waters — to deliver spa-quality results at home.

The brand is particularly celebrated for its ultra-concentrated sheet masks and intensive serums, which have earned cult status across Asia for their visible, immediate results. Spa Treatment products are a favourite among Japanese beauty professionals and are frequently featured in Japanese beauty publications and professional treatment rooms.

The Spa Treatment Philosophy: Professional Results at Home

Spa Treatment was created to bridge the gap between professional aesthetic treatments and daily home skincare. Each product delivers concentrated active ingredients at levels typically reserved for clinic-grade treatments, but formulated for safe, comfortable daily or weekly home use.

The brand's hero ingredient is 100% Pure Hyaluronic Acid — not diluted in a lotion base, but in its concentrated serum form. Their flagship products contain multiple molecular weights of hyaluronic acid alongside collagen, placenta extract, and ceramides, creating an intensive moisture-restoring effect that has made Spa Treatment one of Japan's go-to brands for intensive skin repair and hydration.

Frequently Asked Questions

How often should I use Spa Treatment sheet masks?

For visible results, use 2–3 times per week. Many Japanese users apply them daily during intensive treatment periods (post-sun exposure, seasonal skin changes, or pre-event intensive care). The gentle, predominantly-HA formulas make daily use safe for most skin types.

How do I use the Spa Treatment HA100 Serum?

Apply 1–2 drops to clean, damp skin before your regular moisturiser or toner. You can also mix a drop into your existing moisturiser to boost its hydrating power. Because it is 100% hyaluronic acid, it requires a moisturiser or cream on top to seal in the hydration — HA alone in dry conditions can actually draw moisture from the skin.

Is Spa Treatment suitable for sensitive skin?

The HA-focused products are generally very well tolerated. However, the EGF and placenta-containing products contain more active ingredients — if you have sensitive or reactive skin, start with the pure HA products and introduce other formulas gradually.

What is EGF and why is it in skincare?

EGF (Epidermal Growth Factor) is a protein that stimulates cell division and skin renewal. In skincare, laboratory-derived EGF (also called sh-Oligopeptide-1) is used in anti-ageing products to accelerate surface skin cell turnover, supporting faster recovery from UV damage and reducing the appearance of fine lines with regular use.
