Retinol: Why It Works, How to Start + How I Work It Into Your Routine

Most skincare debates eventually lead back to retinol. It’s one of the most talked about active ingredients, and for good reason. But it also comes with a lot of questions. What does it actually do? How do you introduce it? And isn’t it supposed to irritate your skin?
Let’s unpack it in a way that feels like a conversation, not a lecture, but with the science you actually care about.
What Retinol Actually Does (Science, Not Buzzwords)
Retinol is a derivative of vitamin A and is widely studied for its ability to increase epidermal cell turnover, improve texture, and support collagen production. Multiple peer-reviewed studies show that retinoids remodel both the epidermis and dermis, meaning smoother surface skin plus structural improvement deeper down where fine lines and wrinkles develop.
According to research published in Archives of Dermatology, topical retinol has been shown to stimulate type I procollagen production and reduce enzymes responsible for collagen breakdown in aged skin. That means it does not just improve surface texture. It actively supports dermal repair.
Further reviews in Clinical Interventions in Aging describe retinoids as one of the most evidence-supported ingredients for improving fine wrinkling, texture and overall photodamage through consistent use.
So yes, it does more than cause temporary flaking. It actively changes cellular behaviour beneath the surface.
Why You Might Hear It Can Irritate and How to Avoid That
Retinol accelerates cell turnover, meaning your skin sheds old cells faster. That is excellent for texture and clarity, but it can initially create dryness, redness or tightness if introduced too aggressively.
Retinol is not the same as prescription retinoids such as tretinoin, which have even stronger clinical evidence but are also associated with greater irritation potential. As outlined in dermatology literature on retinoid therapy, irritation is typically dose dependent and improves when introduced gradually. The goal is not discomfort. It is sustainable stimulation that your skin tolerates well.
Gentle Introduction vs Advanced Action
In clinic and on the website, I stock two retinol formulations to meet different needs without turning this into a sales pitch.
A starter strength suited to those new to vitamin A or anyone wanting results with minimal irritation. Even lower concentrations of retinol have demonstrated measurable dermal improvement when used consistently.
A higher concentration for clients who have built tolerance and are ready for enhanced resurfacing benefits. Clinical literature consistently shows that retinoid response is dose dependent, meaning higher strengths can produce greater collagen stimulation when introduced appropriately.
Both are available on my website and in clinic. The recommendation is always clinical and tailored to your skin’s current tolerance and long-term goals.
How I Typically Recommend Using Retinol
Night use only. Retinol increases UV sensitivity, so daily sunscreen is essential.• Start slowly. Every second or third night, increasing frequency as tolerated.• Support the barrier. A gentle moisturiser before or after application helps buffer irritation. Be patient. Noticeable improvement typically takes 8 to 12 weeks, with continued collagen remodelling beyond that timeframe.
For more advanced skincare users, I often recommend a structured approach such as Skin Cycling. This involves rotating active nights with recovery nights to optimize results while protecting the skin barrier. For example, one night of retinol followed by one or two nights focused purely on hydration and barrier repair. It allows for consistent collagen stimulation without overwhelming the skin. It is also one of my preferred long-term maintenance strategies.
This is not a one week glow ingredient. It is a long term structural strategy, which is why it remains one of the most trusted tools for ageing skin, uneven tone and textural concerns.
Final thoughts...
Retinol is not a trend. It is one of the most well studied topical actives available outside of prescription retinoids.
Backed by decades of dermatological research, it works at a cellular level to stimulate collagen synthesis, promote epidermal renewal and improve dermal architecture.
When introduced thoughtfully, it can be transformative without irritation becoming the focus. Think of it as a secure, long term partner and not a toxic situationship.
Every treatment starts with a conversation.
With love,
