Ingredients
11 guides in Ingredients. Skin science without the jargon, plus where Beeuty's selfie analysis fits in.
Ingredient guides explain what an active does, which strength to pick, how often to use it and what to pair or separate it from. Each one is written to be read in ten minutes and acted on tonight.
If you are starting out, read retinol and sunscreen first. If you already use actives and your skin is reacting, read what not to mix and the barrier repair guide before adding anything new.

Glycolic, Lactic or Mandelic? How to Choose and Use an AHA
Alpha hydroxy acids are the surface exfoliants: the ingredients for dullness, rough texture, uneven tone and fine lines. Glycolic, lactic and mandelic all do that job, but at very different speeds and with very different margins for error. This guide explains how to pick the right one for your skin type and tone, what strength and pH actually mean, and how to use it without stripping your barrier.
Azelaic Acid: The Underrated Active for Acne, Redness and Dark Spots
Azelaic acid rarely gets the attention retinol or vitamin C do, yet it is one of very few actives that treats breakouts, persistent redness and the dark marks spots leave behind at the same time. It is gentle enough for rosacea-prone and pregnant skin, and slow enough that most people give up before it works. Here is how to use it properly.
Bakuchiol vs Retinol: Is the Plant Alternative Worth It?
Bakuchiol is marketed as a plant retinol that does the same job without the peeling. The truth is narrower and still useful: it is not a retinoid, it has two small studies behind it, and in one of them it held its own against retinol over twelve weeks. Here is who it suits, how to use it, and where it falls short.
Ceramides: What They Do, Who Needs Them and How to Spot a Real One
Ceramides are the main lipid in your skin barrier, and they drop with age, winter, over-cleansing and heavy use of actives. A good ceramide moisturiser puts them back, but the word on the front of the tube tells you almost nothing. Here is what ceramides do, who needs them and how to read the label.
Skincare Glossary: 67 Terms Explained in Plain Language
A plain-language reference for the words that actually change a skincare decision: what they mean, why they matter, and where to read more. Bookmark it for the next time a label or a forum thread loses you.
Salicylic Acid (BHA): How to Use It for Pores, Blackheads and Breakouts
Most exfoliating acids work on the surface. Salicylic acid is different: it dissolves in oil, so it travels down into the pore and loosens the plug from the inside. That makes it the first ingredient to reach for with blackheads, congestion and oily-skin breakouts, and also the easiest one to overdo. Here is how to use it well.
What Not to Mix in Skincare: Layering Actives Without Wrecking Your Barrier
The internet has turned ingredient mixing into a minefield, and most of the warnings are either outdated or overstated. A few combinations really do cause trouble. The rest are a matter of timing. This guide separates the two, then gives you a weekly schedule that fits retinol, acids, vitamin C and niacinamide into one routine without a single clash.
Vitamin C Serum: The Complete Buyer's and User's Guide
Vitamin C is one of the most-recommended ingredients in skincare, and one of the most-misunderstood. The right form at the right concentration on the right skin is genuinely transformative. The wrong form at the wrong pH does nothing.
Hyaluronic Acid: The Hydration Hero (and How to Use It Correctly)
Hyaluronic acid is the most popular hydrator in skincare and one of the most commonly misused. The trick isn't the product — it's the layer it goes between. Here's the complete user guide.
Retinol for Beginners: How to Start Without Wrecking Your Skin
Retinol has more clinical evidence behind it than almost any other ingredient in your bathroom. It also irritates more new users than almost any other ingredient. Here's how to get the benefits without the burn.
Niacinamide: The Complete Guide to Skincare's Most Versatile Ingredient
If skincare had a Swiss Army knife, it would be niacinamide. It calms oil, soothes redness, fades dark spots, supports the barrier, and plays nicely with almost everything. Here's the complete user's manual.
