Earth Harbor Naturals CELESTINE Hydra-Plumping Peptide Serum
Skin-Nomad's Take — At a Glance
- Deeply hydrates and firms with consistent daily use
- Lightweight water-based formula, all skin types, morning and evening
- Pairs easily under any moisturiser or facial oil
Earth Harbor Naturals, a woman-owned, small-batch brand from the United States, formulates everything without synthetic ingredients. CELESTINE is a strong example of what that approach looks like when it works. This water-based serum delivers eight botanical hydrators alongside fermented sea kelp peptides, Niacinamide, and Pomegranate antioxidants in a featherlight, fast-absorbing texture with a distinctive pale blue-silver colour from organic wildcrafted Blue Yarrow.
Key Benefits
The serum addresses hydration, firmness, barrier health, and tone in a single lightweight step.
- Firms and Plumps with Seaweed Peptides: Fermented Sea Kelp (Lactobacillus/Nereocystis Luetkeana) delivers vegan peptides that support collagen production and improve skin elasticity. The fermentation process enhances bioavailability, allowing the actives to penetrate more effectively than unfermented plant extracts.
- Multi-Level Hydration: Crosslinked Botanical Hyaluronic Acid draws moisture into the skin at multiple depths, while Glycerin and plant-derived Propanediol lock it in and maintain the skin's water balance throughout the day.
- Brightens and Evens Tone: Niacinamide (Vitamin B3) reduces melanin transfer and improves uneven skin tone, while also strengthening the skin barrier and regulating sebum production, making it equally useful for oily and dry skin types.
- Antioxidant Repair from Pomegranate: Punica Granatum (Pomegranate) Extract provides Vitamins C and E alongside polyphenols that protect against environmental oxidative stress and support collagen synthesis.
- Soothes and Calms with Blue Yarrow: Organic wildcrafted Blue Yarrow (Achillea millefolium) has well-established anti-inflammatory and skin-calming properties, making it particularly useful for reactive or redness-prone skin.
Why Choose the Earth Harbor Naturals CELESTINE Hydra-Plumping Peptide Serum?
- Entirely Synthetic-Free: No preservatives, synthetic peptides, parabens, sulfates, or artificial fragrances. The formula relies entirely on plant-derived actives and natural stabilisers.
- Dual-Purpose Texture: The lightweight serum can be applied as a leave-on treatment across the face and body, or mixed directly into a moisturiser or facial oil for a one-step hydration boost, a practical flexibility not common in peptide serums.
- Sustainably Packaged: Glass bottle with recyclable closures using 50% post-consumer recycled plastic.
- Suitable During Pregnancy: The formula is free from retinoids, synthetic actives, and sensitising compounds, making it appropriate for use during pregnancy and breastfeeding.
Ideal For
- Skin types: All skin types, including dry, oily, combination, sensitive, and mature skin
- Skin concerns: Dehydration, loss of firmness and elasticity, fine lines, uneven tone, redness, dullness
- Best used by: Those wanting a single hydrating serum that also addresses early signs of ageing; anyone with sensitive skin looking for a peptide formula without synthetic irritants
FAQ
Q: Can I use CELESTINE with a retinol or AHA serum?
A: Yes. The formula contains no actives that conflict with retinol or acids. If layering, apply CELESTINE first as a hydrating base, then your acid or retinol treatment, finishing with moisturiser.
Q: Why does the colour fade over time?
A: The blue-silver colour comes from organic wildcrafted Blue Yarrow, which is subject to natural variation between harvests and can fade with light exposure. This is entirely normal and does not affect the formula's efficacy.
Q: How long before I notice results?
A: Most users notice improved hydration and plumpness within the first few days. Firming effects from the peptide complex generally become visible after four to six weeks of consistent daily use.
For skin that needs serious hydration and gradual firming delivered through a genuinely natural, peptide-led formula, the Earth Harbor Naturals CELESTINE Hydra-Plumping Peptide Serum delivers both without compromise.
