Vitamin A delivers some of the most significant long-term results available in skincare. Smoother texture, refined pores, softer lines, improved elasticity and more even tone. Used consistently over months and years, vitamin A works at a cellular level to keep skin renewing, collagen synthesising, and the processes that maintain healthy, vital skin functioning well for longer.
The secret to getting there is understanding what your skin is doing at each stage, and staying consistent long enough to let it happen.
What is happening in your skin week by week?
Vitamin A works by influencing gene expression in skin cells. It signals them to behave like healthier, younger cells, stimulates collagen synthesis, and accelerates the natural cell renewal cycle. These are not superficial changes, which is why they take time to become visible.
In the first two weeks, the changes are mostly beneath the surface. Cell turnover is beginning to accelerate and your skin is adapting to the increased activity. Some people notice mild purging or flaking during this period, which is normal and temporary. The introduction phase — frequency, application, and what to expect — is covered in full in How to start a retinoid routine without irritation.
By week four, the accelerated renewal cycle is establishing itself. Skin typically starts to feel smoother to the touch and looks more even in tone. The dullness that builds up from slow cell turnover begins to lift.
By week eight, collagen synthesis is increasing and the structural improvements start to show. Fine lines appear softer, pores look more refined, and skin has a clarity and brightness that reflects genuine cellular renewal rather than surface hydration.
By week twelve and beyond, the results compound. Skin texture is noticeably more refined, tone is more consistent, and the cumulative effect of months of accelerated renewal becomes clearly visible. This is when people describe their skin as looking like a better version of itself — not dramatically different, but consistently healthier and more vital.
How do you know when you are ready for a stronger retinoid?
The signals are straightforward. If you have been using Superstar consistently for at least eight to twelve weeks, your skin has been tolerating it well without significant irritation, and you are seeing positive results but want to go further, you are ready for Superstar+.
At 1% HPR, Superstar+ works at a greater depth to resurface more intensively, stimulate collagen more significantly, and address advanced concerns including deeper lines, loss of elasticity, and hyperpigmentation. Your routine stays identical. The concentration increases fivefold and results over the following months reflect that. A full comparison of both strengths is in How to unlock your best skin with Vitamin A.
Why vitamin A is a long-term investment in your skin
Skin longevity is about supporting the processes that keep skin functioning well for longer. Collagen production declines from the mid-20s onwards. Cell renewal slows. The skin's ability to repair and regenerate diminishes gradually with time.
Vitamin A is one of the most evidence-backed ingredients available for supporting these processes. Used consistently over months and years, it maintains the renewal cycle, supports collagen synthesis, and keeps skin functioning closer to its optimal capacity. The results visible at twelve weeks are just the beginning. The skin you are building with consistent vitamin A use at thirty is the skin you will be grateful for at fifty.
This is pro-age skincare in its most straightforward form: not fighting the clock, but investing in what your skin needs to stay healthy and vital for the long term.
Build your complete ageing skin routine
Superstar sits at the heart of our Ageing Skin Routine — a complete system built around ingredients that support skin at every stage of the renewal cycle. Alongside HPR, the routine brings together squalane for deep barrier reinforcement, superoxide dismutase to neutralise the free radical damage that accelerates visible ageing, peptide technology to support collagen and elastin production, sodium hyaluronate to maintain optimal hydration at a cellular level, and algae extract to firm and protect.
Together, they address every dimension of skin ageing — barrier, hydration, collagen, cellular renewal, and oxidative damage — in a routine simple enough to sustain for the long term.
