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.

- 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
