Blue Hour Serum FAQ

What is Blue Hour Serum?

Blue Hour is a 30 ml hydrating cosmetic serum with glycerin, sodium hyaluronate, copper tripeptide-1, niacinamide, bifida ferment filtrate and centella. It is a simple step between cleansing and moisturizer.

How do I use it?

Apply 1–2 pumps to a freshly cleansed, slightly damp face and neck. Let it absorb, then follow with moisturizer. If using during the day, follow with sunscreen before makeup.

What should I avoid layering with it?

Do not layer in the same routine with direct vitamin C (L-ascorbic acid) or AHA/BHA exfoliating acids. For external use only. Avoid contact with eyes; rinse with water if contact occurs. Stop use if irritation or redness persists. Keep out of reach of children.

Does it contain fragrance, essential oils or retinol?

The labeled ingredient list contains no added fragrance, essential oils or retinol. That does not guarantee that every skin type will tolerate it. Patch test before first use and introduce one new product at a time. Blue Hour has not been shown in a human sensitive-skin study to be suitable for everyone.

What is the full ingredient list?

Water, Glycerin, Bifida Ferment Filtrate, Niacinamide, Sodium Hyaluronate, Copper Tripeptide-1, Phenoxyethanol, Sodium Polyacryloyldimethyl Taurate, Centella Asiatica Extract, Ethylhexylglycerin, Hydroxyacetophenone, 1,2-Hexanediol.

What does the supplier’s 1% copper peptide declaration mean?

The supplier declares 1% Copper Tripeptide-1. This is a supplier declaration, not independent verification of pure GHK-Cu in a finished Blue Hour batch. A percentage alone does not establish how a product will perform.

What results can I expect?

Glycerin and sodium hyaluronate are humectants used to help skin retain moisture. Ingredient research does not prove results for the finished serum. Blue Hour has no verified human efficacy study establishing overnight results, collagen changes or equivalence to retinol. Individual experiences vary.

Where is Blue Hour made?

Made in China by Guangzhou Baiyanhui Cosmetics Co., Ltd. Distributed by Mora Lora LLC for Only Child.
