Four stages, one continuous piece of skin: prep, the session, recovery, and the years afterwards. Each has different evidence behind it, and different amounts of it.

Prep

Skin that is intact, hydrated and not currently irritated is a better starting point than skin that is not. Dermatology describes the barrier as four interdependent layers — physical, chemical, microbiologic and immunologic — and describes how moisturisers support it: occlusives reduce transepidermal water loss, humectants draw water in, emollients integrate into the stratum corneum — that is, the water that evaporates continuously through skin, and the outermost layer it evaporates through. Harsh detergents and alcohol-heavy products work against that.

What prep does not do is change the outcome of the tattoo. It changes the condition of the skin the artist is working on. Anyone claiming more than that is claiming more than the evidence supports.

The session

FDA guidance describes ink deposited roughly 1.5–2 mm below the surface, into the dermis, and notes that the process can cause bleeding. Sterility during the session is a studio responsibility: the CDC recommends sterile ink products and, where dilution is needed, sterile water, and has documented outbreaks where those conditions were not met.

Recovery

The evidence here is the clearest in the whole ritual, and it points away from the folk instruction. Research in Nature found dry scab formation slows epithelialization — the spread of new surface skin cells across an open area to close it over — and that preventing the scab markedly increases the rate. Occlusion research reported improved re-epithelialization compared with air exposure. Practically: avoid cracking dryness, avoid saturation, keep it clean, don't pick.

Watch for what the CDC describes as the serious end — spreading redness, fever, escalating pain, pus, persistent nodules — and treat those as medical, not cosmetic.

Nourish

Long-term appearance comes down to two levers with published support behind them. Ultraviolet exposure: the AAD states UV light can fade tattoo inks and recommends broad-spectrum, water-resistant SPF 30+. And barrier condition: regular moisturisation supports barrier function, and the AAD specifically suggests water-based lotions or creams for dry tattooed skin, noting petroleum-based products can cause ink to fade.

Where our products fit — and where they do not

We make products for each stage. What we can describe is the ingredient and the sensation: what is in the bottle, and how it feels on skin. What we will not do is attribute a physiological outcome to a formula, because no published trial compares tattoo aftercare products against each other for long-term appearance. The full ingredient lists are in The Formula.

A tattoo cared for with a wet cloth, a plain water-based moisturiser and consistent sunscreen is being cared for correctly. That should be true on a page written by a company that sells alternatives, or the page is not worth reading.
