What’s Behind the Q10 Sign aka The Inkey List Q10 Review. DHC Medicated Q 0.3% Lotion Also Here

What is Q10?

Q10 aka ubiquinone is naturally skin occurring coenzyime. It’s making our skin nicely tight (in a good way) and supple. Unfortunately, its production slowly decreases after age of 20 resulting in forming visible wrinkles and causing skin sagging. Good news is you can supplement it topically with cosmetics. In good skin care products Q10 absorption is very good and skin really can benefit from it. Read this study: Topical treatment with coenzyme Q10‐containing formulas improves skin’s Q10 level and provides antioxidative effects (Anja Knott et al.): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4737275/

I am currently enjoying two products that have Q10 in their very name. One is Q10 highly concentrated Japanese lotion (or toner as described here) DHC Medicated Q 0.3% Lotion and the other one is serum from The Inkey List (I mentioned them here) simply called Q10.

The Inkey List Q10


Here is what The Inkey List claims their Q10 serum to be:

A powerful antioxidant that is naturally found in the body, it can protect the skin from damage caused by environmental stressors such as pollution.

A naturally occurring enzyme, Q10 works in the upper layers of the skin to help prevent damage and repair. Q10 levels diminish over time, so using Q10 can help to protect the skin from damage that can accelerate signs of ageing.

Q10 acts to:

– Target fine lines

– Reduce fine lines

– Reduce wrinkles

– Hydrate the skin

Key features:

– SYN TACKS is a dual peptide that helps provide collagen boosting benefits

– Squalane to hydrate and protect skin

– Suitable for all skin type

Q10 is an amazing antioxidant for protecting the skin from damage and targeting signs of ageing. Whilst both Vitamin C and Q10 are antioxidants, Q10 is a great choice for those who find Vitamin C irritating or have more sensitive skin. /The Inkey List/

Ok, very ambitious claims, but do they live up to our expectations?

The Inkey List Q10

The Inkey List Q10 comes in 30ml / 1fl.oz. plastic bottle with the press cap. Yellowish, rather thick serum doesn’t leave sticky or oily residue on skin. No fragrance, no smell whatsoever.

How to use it?

The Inkey List Q10

Use AM and PM. On cleansed skin apply a pea-sized amount to the fingertips and gently pat into the face and neck. Can be used alongside other serums and followed with moisturiser. This product can be use alongside all other INKEY list products.

Works well with: Hyaluronic Acid, Collagen, Retinol.

INKEY Tip: Add to moisturizer for added protection against environmental damage. /The Inkey List/

Nothing to add here. I love using it prior highly concentrated retinol serums or creams. You know, to boost that antiaging effect.


The Inkey List Q10 Ingredients

Water (aqua/Eau), Butylene Glycol, Propanediol, Glycerin, Dicaprylyl Carbonate, Caprylic/capric Triglyceride, Dimethicone, Hydroxyethyl Acrylate/sodium Acryloyldimethyl Taurate Copolymer, Caprylyl Glycol, Squalane, Phospholipids, Lecithin, Glycine Soja (soybean) Extract, Carbomer, Polysorbate 60, Tocopheryl Acetate, (17th) Ubiquinone, Disodium Edta, Sodium Hydroxide, Glycolipids, Glycine Soja (soybean) Sterol, Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine, Palmitoyl Dipeptide-5 Diaminohy-droxybutyrate, Leuconostoc/radish Root Ferment Filtrate, Hyaluronic Acid, Phenoxyethanol

(from the actual packaging. Ingredients list varies from website to website)

And here is where my questions begin to raise. The very name ingredient Q10 (ubiquinone) is only at 17th place of this list meaning its concentration is rather low. Concentration of the first ingredient, in this case water, is defining the type and the quality of the skin care product, is it a water or oil based product etc. Cheaper, drugstore if you like, cosmetics has the water percentage very very high which means the other active ingredients are only in low concentrations water bathing. This ingredients list is rather diluted, so to speak, and definitely not an antiaging bomb as The Inkey List claims it to be.

Nevertheless, these ingredients are nice enough to form the moisturizing serum that skin can enjoy. But it will not kill your wrinkles.

Just to compare with the “serious” Q10 product, DHC Medicated Q 0.3% Lotion. As its name says 0.3% is ubiquinone concentration and that’s considered high. Here is the ingredient list:

DHC Medicated Q 0.3% Lotion

DHC Medicated Q 0.3% Lotion ingredients:

Water, Butylene Glycol, Glycerin, Sorbitol, Pentylene Glycol, Phenoxyethanol, (7th) Ubiquinone, Acetyl Glucosamine, Serine, Sodium Citrate, Elaeis Guineesis (palm) Oil, Caprylic/Capric Triglyceride, Polyglyceryl-10 Oleate, Polyglyceryl-10 Stearate, Dipotassium Glycyrrhizate, Lysolecithin, Allantoin, Citric Acid, Magnesium Ascorbyl Phosphate, Sodium Hyaluronate, Carboxymethyl Chitosan Succinamide, Soluble Collagen, Hydrogenated Lecithin, Placental Protein, PEG-60 Hydrogenated Castor Oil, Tocopheryl Acetate

See, the 7th place. Do your math knowing ubiquinone is in the 17th place in The Inkey List Q10.

You can tell how high concentration of Q10 is in skin care products by their colour. The yellower the higher concentration of Q10 there is. Just to compare these two:

Rosacea safe?


Who is it for?

All skin types

Does it work?

And now the final test; how does my skin enjoy these products?

As for The Inkey List Q10 I can say it definitely boosts other moisturizing products leaving my skin well moisturized and supple. I love how it works with retinol products and really complements other anti-wrinkle products. However, for the full Q10 experience I love to use it after DHC Medicated Q 0.3% Lotion. That’s the Q10 product and I definitely recommend it to anyone.

Skin soothing, moisturize booster, skin “thickener”, wrinkles almost-killing, those are all things that DHC Q10 does to my skin. The Inkey List Q10 is merely its humble sidekick. Or even better, The Inkey List Q10 is great wingman to the real hotshot – DHC. Imagine those Japanese perfect complexions.

Perfect skin for perfect selfie

First, the toner packed with Q10 and then rather lush textured serum. Not a bad combo.

Thumbs up?

Yes. And excited YES! to DHC Q10


    1. Thank you! Both products are good, but DHC is much better. But I gotta mention the price point. The Inkey List is under 10GBP and USD, DHC is 20+USD for travel size (2 fl.oz./60ml). Full size (5.4 fl.oz/160ml) is 35+ USD/GBP
