CELESTINE puts both into a bouncy, water-based serum built on fermented sea kelp, niacinamide, hyaluronic acid and tremella mushroom. Earth Harbor Naturals, a US brand founded by a toxicologist and herbalist, built this serum around plant amino acids and marine ferments, and its blue-silver colour comes from blue yarrow rather than a dye.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant amino acids cushion the surface.\u003c\/strong\u003e Hydrolysed rice and pea proteins, which Earth Harbor calls bio-peptides, sit alongside proline and glycine, amino acids the skin uses to build its own collagen. They hold water at the surface for a smoother, plumper look. Earth Harbor reports that 94% of people testing it found their skin firmer and more supple.*\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNiacinamide evens tone and steadies oil.\u003c\/strong\u003e It limits how much melanin reaches the surface and prompts the skin to make more of its own ceramides, which is why it suits dry and oily skin equally.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHyaluronic acid and tremella hold water in two ways.\u003c\/strong\u003e Sodium hyaluronate binds water at the surface, and tremella mushroom extract forms a light, water-holding film of its own, with glycerin and betaine drawing more in behind them.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSea kelp ferment and seaweed support a calm, balanced surface.\u003c\/strong\u003e Lactobacillus-fermented kelp and Laminaria seaweed bring minerals and ferment by-products, while blue yarrow settles visible redness.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTexture \u0026amp; Finish\u003c\/h3\u003e\n\n\u003cp\u003eA light, bouncy serum that spreads easily and absorbs to a soft, hydrated finish with no stickiness.

Many firming serums use synthetic signal peptides made to a precise sequence, such as Palmitoyl Tripeptide-1. CELESTINE uses hydrolysed rice and pea proteins, broken down into short chains and amino acids, plus free proline and glycine. They hydrate and smooth the surface well; if you want a named, sequence-specific peptide, a synthetic peptide serum is the route for that.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Does the lactic acid make this an exfoliating serum?\u003c\/strong\u003e\u003cbr\u003eA: No. Lactic acid sits near the end of the list with the pH adjusters, and at that position it keeps the formula at the right acidity rather than resurfacing the skin. The serum is gentle enough for twice-daily use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use it with vitamin C or retinoids?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Apply it after cleansing and any toner, before moisturiser, and in the morning finish with sunscreen. Niacinamide and hyaluronic acid sit comfortably alongside vitamin C in the morning and a retinoid at night.\u003c\/p\u003e\n\n\u003cp\u003eThe blue in the bottle is yarrow, not colouring, which tells you something about how the rest of the formula was put together.\u003c\/p\u003e\n\n\u003cp class=\"sn-claims\"\u003e\u003csmall\u003e* Earth Harbor's published results: 97% more hydrated, 94% firmer and more supple skin, 97% reduced fine lines and wrinkles, 94% more even tone and texture and 94% refined pores; timeframe not stated.
