Beauty, explained.

Ganesia is an English magazine about skin, beauty and aesthetic medicine: what an ingredient does at which concentration, in what order a routine goes on, how much sunscreen a face really needs, and what a treatment costs you in downtime. 15 interactive tools turn the reading into something you can try on yourself, and every result becomes a picture you can share.

Three minutes for your skin.

Each pillar starts with a small exercise you can do right here, then hands over to the full tool and its shareable card.

Skincare

How much sunscreen is enough?

Every SPF number on a bottle is tested at 2 milligrams per square centimetre. Most people apply a quarter to a half of that and get a fraction of the protection. Pick the areas you cover and see the amount in grams and teaspoons.

The SPF Day Planner adds the UV index, your phototype and your hours outdoors, and turns it into reapplication times and a card.

1.2grams

About a quarter of a teaspoon for face and neck.

Four pillars

What the magazine covers.

The guides and tools sort into four fields. Together they cover most of what people ask a dermatologist, a facialist and an aesthetic practitioner.

Interactive tools

Small instruments for your skin.

Each tool is built around a number or a decision you can act on. When you have a result, the page draws it as a card you can download or share.

In depth

Four threads that run through everything.

The barrier

Most skin problems start with too much, not too little

The outer layer of the skin is a wall of dead cells in a mortar of ceramides, cholesterol and fatty acids. Acids, retinoids and scrubs all thin that mortar a little. Stacked nightly, they thin it a lot, and the result reads as stinging, flaking and a sudden crop of small bumps.

The Barrier Check turns ten signs into a status and a 14-day plan. The Routine Architect makes sure the actives never land on the same night.

The evidence

An active is a dose, a pH and a number of weeks

L-ascorbic acid works at 10 to 20 percent below pH 3.5. Niacinamide is studied at 2 to 5 percent. Tretinoin trials report their first changes at 12 weeks and their strongest at 24. An ingredient without those three numbers is a marketing claim, not a plan.

The Results Timeline shows when each active usually delivers, so that nobody stops at week 3. The Retinoid Ramp Planner spreads the first weeks so that the skin keeps up.

The shelf

Beauty has expiry dates, undertones and a lot of folklore

Mascara lasts 3 to 6 months once opened. A vitamin C serum turns orange when it is done. An undertone does not change with a tan, and the float test for hair porosity mostly measures product residue. The Beauty pillar sorts the useful habits from the inherited ones.

The Undertone Finder ends with six colours that flatter you, the Shelf-Life Tracker keeps your open-jar dates, and the Hair Porosity Check replaces the glass of water.

The consultation

A treatment is a medical procedure, however small the needle

Botulinum toxin takes 14 days to show its full effect and lasts 3 to 4 months. A hyaluronic acid filler can be dissolved, which is exactly why the person injecting it should have the enzyme in the room. The Aesthetics pillar explains what each family of treatments does, and what to ask before anyone touches your face.

The Aesthetics Compass matches a concern to treatment families, the Recovery Planner draws the downtime on a calendar, and the Consultation Checklist gives you the questions.

From the guides

Answered with numbers.

24 guides across four pillars. Each one answers its question in the first paragraph and names its sources.

The actives, one by one.

Each entry gives the concentration that was studied, the pH it needs, what it pairs with and how many weeks it takes.

12
weeks before a first line acne course is judged

NICE sets a 12 week first line course and asks clinicians to explain that visible change can take 6 to 8 weeks, so a treatment abandoned in week 4 has not really been tried.

55
percent of California emergency departments held hyaluronidase

A survey of 330 emergency departments in California found only 55 percent had immediate access to hyaluronidase, so the clinic injecting your filler should hold its own supply.

1
cm of new hair a month

Scalp hair grows about 0.35 mm a day, near 1 cm a month, so the ends of shoulder length hair are roughly 3 years old and still carry every bleach and every hot iron since.

kDa is the largest chain shown to cross, and only in ex vivo skin

Raman imaging of ex vivo human skin sections found hyaluronic acid of 20 to 300 kDa crossing the stratum corneum and 1000 to 1400 kDa staying on top, with nothing between the two ever applied.

5
percent of UV is all mineral filters reflect

In integrating sphere measurements zinc oxide and titanium dioxide reflected 4 to 5 percent of the ultraviolet reaching them, less than an SPF of 2, so absorption does almost all the work.

6
weeks before a topical acne treatment can be judged

The United States tretinoin label says more than 6 weeks of therapy may be needed before definite benefit shows, and NICE puts noticeable improvement at 6 to 8 weeks, which makes week 6 the earliest honest checkpoint.

treatment families weighed against one concern

Thirteen families cover ten concerns, but only 2 of them work on unwanted hair, and the only families that put lost volume back are injected.

28
days for one skin renewal cycle

One renewal cycle takes about 28 days in young adults and 40 to 60 days after 50, so texture answers in 1 to 2 cycles while pigment and collagen need 3 to 6.

About the magazine

What Ganesia stands for.

Ganesia is an editorial offer, not a clinic, not a shop and not a brand. It explains, it lets you try things on yourself, and it says where the evidence ends.

Independent

Nothing to sell you

No products, no clinics, no affiliate links. The magazine earns nothing from what you decide to put on your skin or who you book.

Reviewed

Editorially accompanied

Every text is read and signed off before publication. Whoever stands behind it is named in the legal notice.

Plain

Numbers with their limits

A before-and-after picture is not a trial, and a cell culture is not a face. Where an effect is proven, we say so. Where it is not, we say that too.
