The Ordinary Quick Starter Guide

The Ordinary is really confusing, especially if you’re new to skincare, so here´s The Ordinary quick starter guide.  

Did you know you can ask Deciem for a free personalised regimen or you can buy one of the complete skincare routines.

If you decide 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!

Buy a few, see how you get on, and then buy more as and when you need.    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 in, then I´d say you’re using too many.

Skin Type & Skin Concerns

Firstly, think about your skin type and concerns.  Be realistic about how many skin concerns you can tackle at once with a serum.  The main skin types are normal, dry, oily, combination and sensitive but there are many combinations.  Skin concerns include acne, pigmentation, rosacea, lines and wrinkles, melasma, eczema and many more. Read more about The Ordinary Regimens.

Choosing A Regimen

You’ll find lots of different Deciem Regimens here plus 100s of personalised 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 products in their categories here. Don’t buy too many of one category, you don’t need them all, save your money!   The Ordinary Products.

Layering 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.


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.  Search #cleansers #doublecleansing.  Deciem have 4 cleansers; The Ordinary Squalane Cleanser, Hylamide Face Cleaner and NIOD LVCE Low Viscosity Cleaner & NIOD SS Sanskrit Saponins. I’ve used all of these and love NIOD LVCE. The most surprising one is the Hylamide Face Cleaner, it´s amazing at removing all makeup, especially difficult mascara and whilst it´s an oil it doesn´t leave your skin feeling oily at all. The Ordinary Squalane Cleanser is my favourite to take away with me when travelling. 50ml is perfect for hand luggage.

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 Surival 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.

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 incorporating it so you can be sure all the products can be used together. Don’t buy too many products of the same solution or category 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.
