Guides

Eleven guides, written to be useful on their own whether or not you ever open the app. No account, no email capture.

Identification

Blackheads or sebaceous filaments?

Two things that look almost identical. One is a clog worth treating; the other is normal anatomy you cannot remove — and trying is how people damage their skin.

Method

What order to apply things in

Layering order changes how well products absorb and work. One rule covers almost every case.

Ingredients

Salicylic, glycolic or lactic acid?

Three exfoliants that do genuinely different jobs. Picking the wrong one is the usual reason exfoliating goes badly.

Causes

Why dark circles happen

Four common causes needing four different responses. Most eye creams address only one of them.

Medicines

Steroid creams: why they need a prescription

They work, which is why they get misused. What long-term facial use does, and why borrowing someone's tube is a bad idea.

Nutrition

Eating for your skin

Which nutrients genuinely affect skin, which foods carry them, and why food beats supplements for almost everyone.

Habits

Water and your skin

What hydration actually does, what it does not, and a calculator for a sensible daily target.

Causes

Facial puffiness, salt and fluid balance

Why your face is puffy in the morning, what sodium and potassium do, and which fixes are real.

Decisions

Before you consider cosmetic surgery

The costs, risks and psychological factors clinics rarely lead with, and the questions worth asking first.

Ingredients

Retinoids: what they do and how to start

The most evidence-backed ingredient in skincare, and the one most people quit in week three. How to introduce one without the irritation.

Ingredients

Chemical or mineral sunscreen?

How the two genuinely differ, why "natural sunscreen" is a marketing term, and the three things that matter more than either.
