Why trust us

How we write these guides

Types, not hype

We describe ingredient and product types in general terms instead of ranking brands with numbers we can’t verify.

No invented data

No fake star scores, no “best-seller” counts, no before-and-after fiction. If we can’t verify it, we don’t publish it.

Patch test first

Skin is personal — what suits one person can irritate another. We always recommend patch testing and asking a dermatologist when in doubt.

Honest about money

Some links are affiliate links. We earn a small commission at no extra cost to you, and we’re never paid to recommend a brand.

This page is general information about skincare ingredient types, not medical advice. Everyone’s skin is different — patch test new products and consult a dermatologist before starting anything if you have a skin condition, allergies, or are pregnant.
Good to know

Frequently asked

Do you use star ratings or rankings?
No. We never invent star scores, ratings, “best-seller” counts, or before-and-after results. We describe product and ingredient types in plain language so you can decide what suits you. Anything we can’t verify, we don’t publish.
How do you choose what to feature?
We organise guides by skin type, concern and ingredient family — the way people actually shop. Within each guide we explain what a product type does and who it tends to suit, drawing on published ingredient science, and we flag where evidence is limited.
Are the shopping links affiliate links?
Some are. As an Amazon Associate we may earn a small commission from qualifying purchases at no extra cost to you. We are not paid to recommend any specific brand and only describe ingredient types in general terms.
Is this medical advice?
No. These guides are general information about skincare ingredient types, not medical advice. Skin is personal — patch test new products and consult a dermatologist if you have a skin condition, allergies, or are pregnant.
