The difference between retinoids, retinol, retinal and retin-A

Retinol, retinal, same-same… right? Not so much.

There’s a few differences between retinoids, retinol, retinal and retinoic acid (retin-A), and because we know how easy it is to get overwhelmed with skin care jargon and ‘magic’ ingredients, we’ve looked to an expert to help us make sense of it all.

Below, Dr. Ginni Mansberg, founder of ESK – Evidence Skincare, helps decode the difference between these forms of vitamin A, so you can know exactly what it is you’re looking at on the label.

Retinoids

Think of retinoids as the head of the vitamin A family.  According to Mansberg, “Retinoids are a class of chemical compounds that are vitamers of vitamin A – an ingredient strongly linked to a myriad of skin repairing benefits, including anti-ageing.”

This includes the strongest, prescription only form, Retin-A  or over-the-counter varieties which are your retinol or retinyl palmitate’s, the weaker forms.

Other types of retinoids you may have heard of could include retinaldehyde and tretinoin.

Retinol 

Under the retinoid umbrella, sits retinol. Retinol  is the most scientifically proven anti-ageing ingredient and easily the most popular form. As Mansberg says, “[it’s] widely accessible to consumers in a range of over the counter creams, serums and lotions”.

This specific type of retinoid is on the recommended list of almost every skin expert, and with decades of research behind it, there’s no question to why. It converts into an active vitamin A in two steps, while significantly reducing fine lines and wrinkles, fading pigmentation and improving skin elasticity.

Retinol esters

Sometimes sensitive or reactive skin can become irritated by the retinol. Or if you’re new to retinoids, you may want to start out on a more gentle form. This is where we look to Retinol esters, a slightly weaker form of retinoids, as they convert to an active vitamin A in three steps.

These can include:

Retinyl propionate:

The most effective retinol ester, in high doses can be beneficial in reducing wrinkles and pigmentation

Retinyl palmitate:

 A weak retinol ester, which has shown benefits in sun damage.

bh recommends: L’Oréal Paris Revitalift Day Cream, Swissline Cell Shock Age Intelligence™ Youth Booster – Retinol + Retinyl Palmitate

Retinaldehyde

Also known as retinal. Just to confuse you.

This form converts into an active vitamin A in just one step, which makes it one of the more potent varieties. In fact, according to Mansberg, 20 times more potent than retinol.

This particular form works faster than retinol, and can be more effective in clearing acne, treating sun damage, and reducing wrinkles.

Retin-A

These are your prescription only forms of retinoids as they can hold some serious side effects.

As they are pure retinoic acid and there is no conversion process required, they are the strongest form of retinoids.

These forms are commonly prescribed for severe acne treatment. Tretinoin (the most widely prescribed retinoid), tazarotene (the strongest topical retinoid), and isotretinoin (which is the active ingredient in common acne medication Roaccutane).

  1. I started at the 0.2% and recently hit 0.5% too!

    And if I have any breakouts that pop up I use Niacinamide (usually around my time of the month), I have such sensitive skin and so hormonal so I do alternate a few things.

  2. Oh cool we are using the same thing! I started slowly on the 0.5% as it was my first retinol (was using granactive retinoid 2% for a couple of years). So far no peeling or irritation. Went a bit mad on my TO purchases and still have a bottle of 5% granactive retinoid (which is supposed to be about the same strength as 0.5% retinol), after that I’ll try moving up to 1% retinol 😛

    Niacinamide is great isn’t it. Good for making skin more tolerant to other treatments too. I am impressed that you can use the retinol given that you have sensitive skin. Did you have to ease into it?

  3. That’s a good plan!!

    I still have a few other TO items in my stash I have to use (but cannot recall which, ones) I do have the caffeine eye on that I am using.

    Yes, I very very very carefully eased in so I did it once a week first week, then twice a week for 2 weeks, then three times a week for 2 weeks and so on 🙂 so it took me ages to get up there.

    I find it interesting though, it really does just depend the brand I recently had a reaction to little ol’ Avene (for a simple clay mask/moisturiser) so I think my skin is sensitive to “certain things” and it’s hard to sometimes pinpoint exactly what it is causing a reaction. One brand for example, that many rave about is GlamGlow and that one just burns for me immediately.

  4. Great information and product recommendations. Gives me a bit of direction as to what products to consider. I was using Neutrogena Rapid Wrinkle Repair cream – I liked it. It worked but the benefits disappeared quite quickly once I ran out of cream. I remember reading about a natural anti aging ingredient that repairs the skin inside out. It was apparently the new ‘Retinol’ but the benefits lasted significantly longer (As it repaired the skin) if you stopped using the cream. Did I just dream about this? Haha or has anyone else heard about it? I can’t find it on google.

  5. I have been using the Ordinary Granactive 2% emulsion for the last few weeks and have noticed a reduction in some of the hyper-pigmentation. This article was great as the naming is very confusing!
