Reserveage Beauty's Tres Beauty 3 focuses on comprehensive beauty support through its blend of specialized ingredients. It notably features Cynatine HNS, a patented form of soluble keratin, and an RA Collagen Blend, which are direct building blocks for hair, skin, and nails. The inclusion of essential minerals like Zinc and Copper, along with key B vitamins (Biotin, B6, Pantothenic Acid, Niacin), provides foundational support for cellular health and various beauty benefits. While the doses of keratin, collagen, zinc, copper, and most B vitamins are generally effective for supporting hair, skin, and nail integrity, the biotin content at 300mcg is relatively modest compared to the higher dosages often found in standalone biotin supplements or other comprehensive beauty formulas on the market. Additionally, the proprietary 'RA Collagen Blend' lacks transparency regarding the specific types and sources of collagen. The product's claims extend to stress relief, energy, immunity, and bone health; however, its ingredient profile provides only indirect or minimal support for these broader goals, primarily through the general roles of B vitamins and zinc. The price per serving is on the higher end when compared to other robust beauty supplements available, which might offer similar or superior ingredient profiles at a more competitive cost.
