Serums and Drops UK: Vitamin C Face Serums, Oral Skin Nutrient Drops and Methylene Blue Solution, Each Sold Under Its Own Rules

Three different things live on this page and we keep them apart. One food supplement in liquid form, whose copper and vitamins carry authorised skin claims. Two cosmetic serums, applied to the face and governed by cosmetics law rather than the supplement register. And methylene blue solution, which is a laboratory and general-purpose product, not for human consumption, and is sold with no health information at all. Which rules apply to which product, and what each can say, below the products.

Three products, three sets of rules

A bottle with a dropper can be a food supplement, a cosmetic or a laboratory reagent, and UK law treats each one differently. A food supplement may only use health claims from the Great Britain register, at the amounts the register requires. A cosmetic is not covered by that register at all; it is governed by the UK Cosmetics Regulation, is applied to the skin, and is described by what it contains and what it does on the surface. A laboratory solution is sold for laboratory, educational and general external use, is not for human consumption, and gets no health information from us whatsoever.

This page is in three parts, in that order. Part 1 is the oral drops, with the claims the register allows. Part 2 is the serums. Part 3 is methylene blue, and the only things we say about it are what it is, what it is for and how to handle it.

Part 1: food supplement drops with authorised claims

Sunless Tanning Liquid Drops 60ml

Oral nutrient drops: copper, vitamins A, C, E, B6 and B12, beta-carotene, lutein, zeaxanthin and L-tyrosine. Copper contributes to the maintenance of normal skin pigmentation; vitamin C contributes to normal collagen formation for the normal function of skin. Not a topical tanner, no UV protection. Contains soya.

The claims in bold are the register wording; the paragraph that follows explains only how the nutrient does it.

Copper contributes to the maintenance of normal skin pigmentation

Copper is a cofactor for tyrosinase, the enzyme that starts the conversion of L-tyrosine into melanin, the pigment that gives skin its colour. Adequate copper keeps that enzyme working normally. This is a claim about normal pigmentation, not about tanning, darkening or a change in skin tone.

Copper contributes to the protection of cells from oxidative stress

Copper is part of the superoxide dismutase enzyme, one of the body's own systems for neutralising reactive oxygen species before they damage cell components.

Vitamin C contributes to normal collagen formation for the normal function of skin

The enzymes that cross-link collagen fibres need vitamin C to work. Collagen is the main structural protein of the skin's lower layer, so normal collagen formation is part of normal skin function.

Vitamin A contributes to the maintenance of normal skin

Vitamin A regulates how skin cells divide and mature as they move to the surface, the process that keeps the skin barrier renewing normally.

Vitamins B6, B12 and C contribute to the reduction of tiredness and fatigue

Each is a cofactor in the pathways that release energy from food; adequate intake keeps those pathways running normally.

Beta-carotene, lutein, zeaxanthin and L-tyrosine

Declared on the label but carrying no authorised claim of their own. Beta-carotene is a source of vitamin A and can be counted towards it; lutein, zeaxanthin and tyrosine are listed for what they are, with nothing promised.

What these drops are not

They do not tan the skin, do not contain a self-tanning agent, do not darken skin tone and do not provide any protection from the sun. Use sunscreen as normal. The word tanning in the product name refers to the market people search in, not to an effect, and the label says so.

Part 2: cosmetic serums, applied to the skin, not the register

5-in-1 Face Serum 30ml

Vitamin C, niacinamide, hyaluronic acid, collagen and vitamin E in one serum. For the face, morning or evening, under moisturiser. Cosmetic: not for consumption.

Shop now →

Vitamin C Serum 30ml with Hyaluronic Acid

A brightening serum pairing vitamin C with hyaluronic acid for hydration. For the face, after cleansing. Cosmetic: not for consumption.

Shop now →

Why the serums do not use the health claims register

The register covers food and food supplements. A serum is a cosmetic, applied to the skin, and is governed instead by the UK Cosmetics Regulation: it must have a product safety assessment, a named responsible person, a full ingredient list in INCI order, and claims that can be substantiated. A cosmetic may not claim to treat or prevent a disease; it may describe its cosmetic effect.

What the ingredients do, in cosmetic terms

Vitamin C in a serum is used for brightening and evening the look of skin tone. Niacinamide is used for the appearance of pores and skin texture. Hyaluronic acid holds water at the surface for hydration. Vitamin E and collagen are conditioning ingredients. These are cosmetic functions, not nutritional claims, and they are different from what the same names mean in a supplement.

How to use a serum

Cleanse, apply a few drops to the face and neck, press in, then moisturise. Vitamin C serums are usually used in the morning under sunscreen. Patch-test on the inner forearm for 24 hours first. Keep the bottle closed and out of light; vitamin C serums darken as they oxidise and should be replaced when they turn deep orange.

Part 3: methylene blue solution, not for human consumption

Read this before you buy

Methylene blue solution is sold on this site for laboratory, educational, aquarium and general external use only. It is not for human consumption. It is not a food supplement and we do not sell it as one. In the UK, methylene blue as a medicine is prescription-only and administered in hospital. We provide no dosing, no directions for ingestion and no information about effects in people, and we will not answer questions asking for them. It stains skin, fabric and surfaces; wear gloves, keep away from eyes, keep out of reach of children, and store closed away from heat and light.

Methylene Blue 1% Solution 60ml

Methylthioninium chloride 1% in purified water, brown glass dropper bottle. Laboratory, educational and aquarium use. Not for human consumption.

Shop now →

Methylene Blue 1% Solution 120ml

The same 1% solution in a larger bottle for laboratory and general-purpose use. Not for human consumption.

Shop now →

What it is

A synthetic thiazine dye, methylthioninium chloride, dissolved at 1% in water. Its ordinary uses are as a biological stain in microscopy, a redox indicator in chemistry teaching, and an aquarium treatment. Those are the uses we sell it for.

What we will not say

Anything about taking it, any amount, any effect in people, any comparison with a medicine. There are websites that discuss ingesting methylene blue; this is not one of them, and no material on our site should be read as encouragement to do so.

Handling

Nitrile gloves; it stains skin for days and fabric permanently. Avoid eye contact; rinse thoroughly if it happens. Not for use in aquaria containing invertebrates without checking suitability. Safety data sheet available on request.

Frequently asked questions

Why are supplements, cosmetics and a laboratory solution on the same collection page?
Because customers search for liquids in droppers and serums together, and the collection is named for the format. The rules are not the same, so the page splits them: the oral drops are a food supplement and use only authorised register claims; the serums are cosmetics under the UK Cosmetics Regulation and are described by what they contain and do on the skin; the methylene blue is a laboratory and general-purpose solution, not for human consumption, and carries no health information.

Can the methylene blue be taken as a supplement?
No. It is sold for laboratory, educational, aquarium and general external use only, and is labelled not for human consumption. Methylene blue is not an authorised food supplement ingredient in the UK; as a medicine it is prescription-only and used in hospital. We do not provide dosing, and we do not describe any effect of ingesting it. Please do not ask us to.

What claims can the Sunless Tanning Liquid Drops make?
Only the authorised claims for the nutrients in them, at the amounts in the daily serving: copper contributes to the maintenance of normal skin pigmentation and to the protection of cells from oxidative stress; vitamin C contributes to normal collagen formation for the normal function of skin; vitamin A contributes to the maintenance of normal skin; vitamins B6, B12 and C contribute to the reduction of tiredness and fatigue. The product does not tan the skin, does not provide UV protection and is not a sunscreen. Contains soya.

Are the face serums supplements?
No. They are cosmetics applied to the skin and are not to be swallowed. Cosmetics do not use the supplement claims register; they are governed by the UK Cosmetics Regulation, which requires a safety assessment, a responsible person and claims that can be supported. Vitamin C, niacinamide, hyaluronic acid and vitamin E are described on the serum pages by their cosmetic function: brightening, hydrating, conditioning.

Can I use the vitamin C serum and take the oral drops together?
They are different routes and different products, so there is no interaction between them. The serum works on the skin surface; the drops supply nutrients through the diet. Patch-test any new serum on the inner forearm for 24 hours before using it on the face.

Is copper safe to take every day?
At the amount in the daily serving of the drops, yes, for healthy adults. Copper has an NRV of 1mg and a supplementary safe upper level well above that. People with Wilson's disease must not take copper supplements. Check with your GP if you take zinc long-term, since the two minerals compete, or if you are pregnant or breastfeeding.

Why is one methylene blue listed as 60ml and one as 120ml?
Two bottle sizes of the same category of product, both 1% solution, both sold for laboratory and general-purpose use and neither for consumption. Choose by the quantity you need. Both stain skin, fabric and surfaces; handle with gloves.

Do you sell these wholesale?
Yes. Serums by the case, the oral drops by the case, and methylene blue solution in larger volumes for laboratory and aquarium trade customers, with the safety data sheet supplied. Use the contact page for a trade price.
