Formulation view Emulsified resurfacing serum led by dulse extract; lactic acid plus gluconolactone form a gentle AHA/PHA system buffered with sodium hydroxide. Squalane, CCT and GLA-rich evening primrose and borage oils replenish lipids; olive esters emulsify; caprylhydroxamic acid, sodium phytate and potassium sorbate preserve. Multiple algae and flower extracts boost antioxidant tone. Suits dull, rough skin at night. Note: precise pH control is critical with acids in an emulsion.

Ingredients explained

Palmaria Palmata Extract
Algae extract for barrier protection; concentration supplier-dependent
Lactic Acid
AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.
Aqua/Water/Eau
Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.
Pentylene Glycol
Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
Caprylic/Capric Triglyceride
Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin
Cetearyl Olivate
Natural emulsifier pairing with glucosides; skin-like feel, biodegradable, prone to oxidation requiring light protection
Squalane
Emollient from plants or synthetic; light texture
Silybum Marianum Seed Oil
Milk thistle seed oil; silymarin-rich, antioxidant, high oil load, prone to oxidation
Sorbitan Olivate
O/W emulsifier, HLB ~15, requires ionic co-surfactant, potential sensitizer.
Glyceryl Caprylate
Mild emulsifier/deodorant at 0.5-2%; polyol ester, high humectancy, low irritancy, check cationic surfactant compatibility.
Glycerin
Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
Sodium Stearoyl Glutamate
Mild amino-acid surfactant, poor solubility, pairs with fatty alcohols, fine foam.
Sodium Hydroxide
Strong base neutralizer for pH adjustment; handle with extreme care
1,2-Hexanediol
Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
Gluconolactone
Multifunctional agent for chelation and permeation; acidic, may irritate at high levels, buffer recommended.
Bellis Perennis Flower/Helichrysum Italicum Extract
Not decoded yet
Hibiscus Sabdariffa Flower Extract
Roselle flower extract rich in anthocyanins, used for skin conditioning and antioxidant support
Algae Extract
Algae extract with humectant and conditioning effects; may contain natural fragrant components.
Gigartina Stellata Extract
Not decoded yet
Chondrus Crispus Extract
Carrageenan for thickening and moisturizing; seaweed-based, pH-sensitive
Haematococcus Pluvialis Extract
Haematococcus pluvialis extract rich in astaxanthin; potent antioxidant; used in anti-aging and photoprotection formulas.
Avena Sativa Kernel Extract
Antioxidant and soothing extract; mild abrasive properties, common in conditioning formulas
Salicornia Herbacea Extract
Sea spinach extract rich in polysaccharides and minerals; primarily for soothing and skin conditioning.
Limonium Gerberi Extract
Not decoded yet
Ribes Nigrum Seed Oil
Blackcurrant seed oil rich in GLA used as an emollient; high in unsaturated fats, prone to oxidation
Oenothera Biennis Oil
Natural oil rich in GLA; supports barrier, prone to oxidation, needs antioxidants
Borago Officinalis Seed Oil
Gamma-linolenic acid (GLA) rich oil; excellent for repair but prone to oxidation, requires antioxidants
Helianthus Annuus Seed Oil
Sunflower seed oil for emollient/occlusive; high linoleic acid, low comedogenicity.
Sclerotium Gum
Non-ionic gum for gels; neutral pH, requires dissolution via heating or fine milling
Xanthan Gum
Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
Caprylhydroxamic Acid
Chelating agent to stabilize metal ions; often paired with antioxidants for system stability, used at low levels
Sodium Phytate
Chelating agent stabilizes metal ions to prevent oxidative degradation; also used in oral care, high safety profile.
Potassium Sorbate
Preservative effective below pH 6; combinable with sodium benzoate
Citric Acid
Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
