Your retinol questions, answered

Last Updated: 6/11/2022

It is a {skin care} truth universally acknowledged, that most of us don’t have a clue when it comes to what {retinol} actually does. We know we need it, we’ve read about its benefits but when it comes to knowing what distinguishes the ‘retinols’ from ‘retinoids’ and ‘retinoic acids’ then we swiftly start to feel a lot light-headed (“Thank you, next!”). Same-same but different, choosing between ‘granactive’ and ‘bakuchiol’ might seem a lot like science class but trust us, understanding how these stellar skin care siblings differentiate will help prolong the health (and vibrancy!) of your complexion.

Wait – so why is retinol good for skin?

‘Retinoids’ is how the beauty realm refers to an ingredient that sits beneath the ‘vitamin A umbrella’ – our body converts carotenoids into vitamin A to maintain healthy vision and optimal brain function and similarly, our skin converts topical retinoids into a format it knows what to do with – retinoic acid.

The potency of retinoids depends on how much work your skin cells have to do. Applying retinoic acid would have near immediate effect – your skin would recognise it and absorb it like a sponge but, never has the phrase ‘more haste, less speed’ felt more appropriate…

How does retinol work?

Essentially an irritant, retinoids encourage sluggish cells to step it up a gear… urging them out of retirement where they resume manufacturing all of the scaffolding needed to keep your face firm, plumped and lineless. Stimulating synthesis of collagen (the building blocks) and elastin (the mortar), retinoids are one of few ingredients that quickly and visibly work – revving your cells’ engines so they act like younger versions of themselves.

However, with anything active its best to tread carefully. Usually prescription only, retinoic acid is reserved for those with chronic skin conditions such as acne (‘Rocaccutane’ is the brand name of ‘isotretinoin’ – a clinical form of retinoic acid) and its list of side-effects goes on… and on. Redness, flakiness and ‘peeling’ are a handful of the all-too-common contraindications, but it isn’t true that retinoids behave like acids; instead this pseudo-foliation is a symptom of accelerated turnover as new and healthy cells cause dulling surface cells to shed.

The rate at which this happens can be regulated – especially now that formulators are devising ways to moderate the cons without diminishing the pros. Micro-encapsulation, buffering with oils and plant-derived alternatives are making all the benefits of retinol accessible to everyone – especially those with a petal-esque skin type.

So when should you start using retinol?

There’s no need to introduce retinol too early (unless it has been recommended to help with blemishes or acne), however prevention is better than cure when it comes to delaying the signs of the passage of time… Collagen synthesis starts to slow-down once you’ve reached your mid 20s, so this is a good time to think about adding a gentle retinol to your routine – maybe on alternate evenings (you could try ‘skin cycling’ to introduce the benefits while minimising risk of any side-effects).

Bakuchiol and retinyl are ultra-gentle ways to introduce the joys of retinol to any skin care ritual. Extracted from seeds of an Indian plant – psoralea corylifolia – bakuchiol (pronounced ba-coochy-ol) mimics the youth-preserving impact of its retinoic cousins but without the tell-tale scales, while retinyl is tougher to convert which means its benefits are gradual; ideal for those who’re looking to postpone the development of fine lines and prolong skin’s youthful dewiness.
