Skin-care guides

Short answers about skin, routines, ingredients and habits. Every guide ends with a next step.

Guide

A routine you can actually repeat

A beginner routine needs three jobs, not ten bottles: cleanse, moisturize and protect from the sun by day. Here is how to start small and keep going.

Guide

Two moments, different jobs

Morning and evening share most steps. The difference is sun protection by day and taking off makeup and sunscreen at night. Here is how to split the jobs.

Guide

Clean, without the scrub

Gentle cleansing means lukewarm water, a mild cleanser and your fingertips. Scrubbing harder does not clean better. Here is what a good wash looks like.

Guide

A toner is a choice

A toner is an optional step, not a required one. Some hydrate, others exfoliate. Here is how to tell whether you want one at all.

Guide

One new product at a time

Add one new product at a time and keep the rest of your routine the same. That is the only way to know what a change did. Here is how.

Guide

Read the sun-protection label

On a sunscreen label, look for broad spectrum, SPF 30 or higher and water resistance. Then check the exact version you are buying. Here is how to read it.

Guide

Does every bottle have a job?

Too many products? Give each bottle a job. If several do the same optional job, that is a reason to simplify, not a sign of a better routine.

Guide

Read a claim without inheriting it

Product names promise a lot. Learn to separate the marketing words from facts you can check, like the product's role, its label and its ingredients.

Guide

Keep pores in perspective

Pores are a normal part of skin, not a flaw to erase. Here is how to keep them in perspective and why squeezing is not the answer.

Guide

A washing plan, not a stopwatch

How often should you wash your face? The general guidance is up to twice a day and after sweating. Here is how to fit it into a normal day.

Guide

Double cleansing has a purpose

Double cleansing means an oil or balm first, then your usual cleanser. It helps with makeup and sunscreen, and is optional the rest of the time.

Guide

You do not owe your skin ten steps

The ten-step routine is a famous idea, not a requirement. A short routine that covers cleansing, moisturizing and daytime sun protection is complete.

Guide

Pack the routine you know

A trip is not the time to test new products. Pack small versions of what you already use, plus enough sunscreen for the days you will be outside.

Guide

Know what your profile does not know

Your skin profile is built only from what you tell it. It helps organise a cosmetic routine; it cannot see your skin, diagnose anything or predict reactions.

Ingredient

Niacinamide

What niacinamide is, what the name on a label can and cannot tell you, and why one good product with it is enough.

Ingredient

Hyaluronic acid

Hyaluronic acid and sodium hyaluronate show up in many hydrating products. Here is how to read the name without buying a step you do not need.

Ingredient

Ceramides

Ceramides are lipid ingredients common in moisturizers. What their presence tells you, and what a ceramide claim does not prove.

Ingredient

Panthenol

Panthenol is a common skin-care ingredient. Why a safety assessment is about uses and amounts, not a promise that it suits everyone.

Ingredient

Centella asiatica

Centella asiatica is a signature K-beauty ingredient. Why a plant on the label does not mean a single-ingredient formula or a guaranteed fit.

Ingredient

Vitamin C

Vitamin C comes in several forms in skin care. Why the form and the headline percentage are separate facts, and a bigger number is not a better match.

Ingredient

Retinol and retinoids

Retinol belongs to the retinoid family, which includes prescription treatments. Why our routine builder never adds it for you, and when to ask a professional.

Ingredient

Alpha hydroxy acids

AHAs are exfoliating acids such as glycolic and lactic acid. Why they need their own directions and can make skin more sensitive to the sun.

Ingredient

Beta hydroxy acids

BHA usually means salicylic acid in cosmetics. Why the abbreviation alone does not tell you how to use a product, and what to check instead.

Ingredient

Polyhydroxy-acid labels

PHA is a broad label for polyhydroxy acids such as gluconolactone. Why a reputation for gentleness is not a guarantee for your skin.

Ingredient

Cosmetic peptides

'Peptides' covers many different ingredients. Why a result reported for one cannot be stretched to every serum that uses the word.

Ingredient

Snail secretion filtrate

Snail secretion filtrate is the label name behind snail-themed products. What the ingredient is, and why it matters for vegan preferences.

Ingredient

Glycerin

Glycerin is one of the most common ingredients in skin care. Why seeing it on a label is useful but tells you little about how the product will feel.

Ingredient

Squalane

Squalane and squalene are different ingredients with similar names. How to keep them apart and what a squalane label does not tell you.

Short read

Water, comfortably warm

A small habit for this week: check the water temperature before you wash, and keep it comfortably warm rather than hot.

Short read

Keep one change visible

A small habit for this week: change only one product, and jot down what and when, so you know what made the difference.

Short read

Give the essentials room

A small habit for this week: set out one product for each basic step and move the duplicates aside to see what you actually use.

Short read

Pause at the label

A small habit for this week: before you rebuy a favourite, check the current name, version and directions on the package.

Short read

Leave one step optional

A small habit for this week: plan one evening without an extra layer and notice that the shorter routine is still complete.

Short read

Plan for the time outside

A small habit for this week: before going out, plan shade, clothing and where your sunscreen will be when you need to reapply.

Short read

Buy for a role

A small habit for this week: decide which step you are shopping for before you open a sale, so the discount does not decide for you.

Short read

Describe what you enjoy

A small habit for this week: describe, in your own words, the texture and the finish you enjoy, as two separate preferences.

Short read

Hands off, spots alone

A small habit for this week: touch your face only with clean hands and for a reason, and leave spots unsqueezed.

Ingredient

Ginseng (Panax ginseng)

Korean ginseng appears on labels under Panax names. What a 2012 safety review concluded, and what that conclusion leaves out.
