The Ordinary Quick Starter Guide – The Beginner´s Guide To The Ordinary

The Ordinary can be really confusing especially if you’re new to skincare. Here´s The Ordinary quick starter guide or your beginner´s guide to The Ordinary which I really hope will make it all a little clearer.

I know you´re excited to get on and buy but please, spend a little time reading and you will save money, time and maybe your skin.

Don’t want to read and just want to get on?

  • Ask Deciem for a personalised routine
  • Buy the products they suggest
  • Layer them in the order they give you
  • Stick to the AM & PM routine for a good few weeks
  • Patch test the products before using.

The Ordinary Names

The names of The Ordinary products are basically the names of the ingredients and the percentages. You have most likely used them already in your other skincare products.

The Ordinary is so confusing

If you are finding it all so confusing, the easiest thing to do is to ask Deciem for a personalized regimen. If you do not to buy a set regimen or ask Deciem for a regimen, you may find yourself spending hours scrolling through the website and Facebook Group posts, get totally overwhelmed and spend more money than you really need to. You´re also likely to buy products that conflict too that could cause irritation to the skin or possible allergic reaction.

Buy a few products, see how you get on and then buy more as and when you need it.    It´s good to stick to a routine to really see the benefits.  If you’re getting stressed and have no idea what order to use them all in, then you´re probably using too many.

The Ordinary Quick Starter Guide

Skin Type & Skin Concerns

Firstly, think about your skin type and concerns.  If you don´t know what your skin type is, have a look at The Ordinary products for every skin type here. Be realistic about how many skin concerns you can tackle at once with a serum.   Skin concerns include acne, pigmentation, rosacea, lines and wrinkles, melasma, eczema, and many more. Read more about The Ordinary Regimens.

What each of The Ordinary Products target

There is the regimen page on the Deciem website that lists the products and their targets. I have created a page so you can look at skin concerns first and then the product. Click here for the best The Ordinary products for all different skin concerns.

Choosing A Regimen

You’ll find lots of different Deciem Regimens here plus 100s of personalized regimens the group members have been sent by Deciem.  Browsing through these will give you a good idea about which products to use together and how many to use in one regimen. Deciem does not recommend more than 3 serums in one routine.

The Ordinary Products

This brand can be really confusing with all the technical names and percentages but these are simply the ingredient names.  I have listed all the different The Ordinary products in their categories here. Don’t buy too many of one category. You don’t need them all, save your money!   

How To Layer The Ordinary

Read all about Layering The Ordinary here where you can see all The Ordinary products arranged by their different solutions; Water, Oil, Anhydrous, Suspension & Emulsion.  The general rule is from the thinnest / clearest to the thickest / opaque. Make sure you read this page which is regularly updated.

The Ordinary Product Conflicts

I have put together this chart which marks all The Ordinary products that conflict. It´s taken quite a lot of work to put together but think it ´s the easiest and quickest way to see all The Ordinary conflicts together. Always check the official pages on the Deciem website and instructions as these are often updated.

The Ordinary Products You Can & Cannot Mix

For those who find the chart a bit confusing, you can now find this page which shows all The Ordinary products you can and cannot use together.

The Ordinary You Can & Cannot Mix


A good cleanser or two is really important because it´s the foundation of your skincare routine, so you want something that´s going to leave your skin feeling really clean and hydrated. We have hundreds of posts in the Facebook Group all about cleansers.  Just search #cleansers #doublecleansing.  

There are 4 Deciem cleansers and you can read all about them here and reviews.

Sun Creams

It is really important to use sun cream every day and reapply when needed.  You should avoid the direct sun when using these products, especially the Acids, Retinols and Retinoids.  We have hundreds of suggestions for sun creams in the Facebook Group and  I´m sure we can find the perfect one for you. Deciem has the NIOD Survival Range, S10, S20 & S30 and also The Ordinary Sun Creams in Factor 15 & 30.

The Ordinary Reviews

When it comes to reviews, the truth is that some people will love a product, some will hate it and some will think it´s just ok.  Read reviews by the Deciem Addicts, the people who have bought, tried and tested. The Ordinary Reviews. These are your reviews!

Keep it Simple

If a product has too many conflicts, for example, Buffet + Copper Peptides, then you could be making life really difficult for yourself by trying to figure out a regimen on your own.  Ask Deciem for a regimen so you can be sure all the products can be used together. Don’t buy too many products of the same solution (water-based, emulsion) or category (acids, antioxidants, etc) and stick to the same routine for a good few weeks for the best results.

Why Start Slowly?

If you use 3 products for the very first time and your skin has a bit of a reaction, how will you know which product caused it? That’s why it´s recommended that you introduce one product at a time.

Patch Testing

Deciem recommends patch testing in case of allergic reactions. We have received a few posts in the Facebook Group from members who unfortunately have had reactions to some of these products as you can with any brand. The majority of people don´t patch test, but you have been warned!

Deciem Regimen Page

If you read one page, please make sure you read the Deciem Regimen Page. It´s so important to know which products conflict, which products should only be used in the evening and how to layer. It´s also important to read the product pages before using them. They explain how to use the product and if a product is nut-free, vegan, oil-free, water-free, silicone-free, gluten and cruelty-free.
