Type tretinoin before and after pores into your search engine, and you’ll get countless amounts of user experiences with improved appearance of their skin after weeks or even months of using the drug regularly. Enlarged and visible pores are one of the main problems tretinoin is used to treat – and it’s not a coincidence at all. But to understand the true mechanism behind tretinoin’s effects on pores, as well as “before and after” that you should expect, you need to know some facts.
The following article is devoted to the real mechanism of action of tretinoin on pores, the realistic timeframe according to modern dermatological research, and methods for achieving the best effect from the treatment.
Can Tretinoin Actually Make Pores Smaller?
And here is the first and most important clarification: the pore size is determined mostly genetically, as well as such characteristics as the size of sebaceous glands and skin elasticity. Tretinoin does not physically make the structure of the pore smaller, as surgery may affect the tissues. However, tretinoin can reduce the pores’ appearance because of the following two major factors:
Pores that are clogged and filled with different substances look as if they are stretched and bigger than the pores that are clear.
The lack of skin elasticity makes the pores look as if their openings were wider. With the aging process and exposure to the sun, the collagen becomes depleted, and, therefore, the skin around the pores loses some of its support.
In this way, tretinoin deals with these two problems: it promotes faster cellular turnover and clearing the pores of congestion, as well as it stimulates collagen production due to its well-known effect on it. The result is a reduced appearance of pores, which is really noticeable, although it is not the change in the pore structure itself.
The Mechanism Behind Pore Improvement
A few specific biological processes are behind tretinoin’s effect on pore appearance:
- Normalization of keratinization: This drug facilitates proper shedding of dead skin cells from pores instead of letting them accumulate and block the opening of the follicle that results in enlarged and congested-looking pores.
- Acceleration of skin renewal: The main principle of the action of this drug is the acceleration of the skin renewal cycle that results in the clearance of the debris responsible for stretched and large pores.
- Stimulation of glycosaminoglycans (GAGs) production: This drug was found to stimulate GAGs production, which are important for skin hydration and elasticity, thus contributing to better appearance of pores due to the effect on the structure surrounding them.
- Collagen synthesis: Same as other effects of tretinoin that are associated with anti-aging activity of the drug, the stimulation of collagen synthesis contributes to the structural integrity of the skin and directly affects the appearance of the pores.
The fact that tretinoin is the only drug among retinoids FDA-approved for photoaging treatment, during which one of the symptoms is enlarged pores, suggests that this is not a random effect of the drug.
A Realistic Before-and-After Timeline for Pores
Based on the most recent dermatological resources and time frames, here is an estimate of what most people may expect:
Weeks 1–2: Adaptation Weeks. Weeks 1–2 will most likely include drying out of the skin, minor peeling, and the absence of any effect on pores. This is the retinization stage, when your skin adapts to the increase in cell turnover without showing its results.
Weeks 2–6: Purging Stage During this time, some people may have a purge, i.e., a period when existing congestion is flushed out faster than usual. As a result, pores and acne may get worse temporarily until they begin to heal.
Weeks 4–6: First Improvements. Weeks 4-6 are usually considered a period when actual improvements in the condition of pores and texture of skin can be observed.
Months 2-3: Visible Results. In about two to three months after the start of using the product, most consistent users can expect smoother skin, clearer pores, and improved skin texture.
Months 3-6: Further Optimization of Appearance. Pore structure and skin texture may be expected to keep improving throughout this period because the effects of collagen remodeling and continuous cell turnover are compounding one another.
Months 6-12: Full Completion of Collagen Remodeling. The most comprehensive improvement in pore appearance and skin tightening will occur during this period because of the slow process of collagen production and skin restructuring.
Consistent message from all the dermatology sources: pore-related improvements are expected to appear somewhat sooner than fine line/pigmentation improvements, which come from tretinoin, yet still take months rather than weeks.
Why “Before and After” Photos Can Be Misleading
There’s good reason to be skeptical about the before-and-after content available online, especially that seen on social media, and for several reasons:
- The lighting and angle used in pictures have a huge influence on how visible the pores look; sometimes more than any actual change in one’s skin.
- Makeup, photo filters, and the ability of cameras to smooth out skin in photos can make “after” pictures look more impressive than what can be achieved using skincare products only.
- Personal results can differ greatly depending on skin type, the underlying causes for enlarged pores (oily skin, sun damage, genetics, aging), consistency of use, and tolerance to the treatment.
- Selective posting; it is natural for people to post pictures showing the most impressive results rather than those with little or no changes, thus distorting the true image of the “typical” result.
That doesn’t mean that tretinoin isn’t effective for shrinking pores, and that the science behind it isn’t true.
Getting the Best Pore-Related Results From Tretinoin
1. Start Slow, But Stay Consistent
Start using tretinoin slowly – just once or twice per week at the beginning, particularly if this is your first time using retinoids – with a low dose such as 0.025% to avoid drying out or irritating your skin. The consistency during the following few months will be more important than quickly moving to stronger dosages or increasing frequency.
2. Don’t Quit During the Purge
The purge period, which usually occurs between weeks 2 and 8 of treatment, is often defined as the point where people are most inclined to stop using the product. It is usually necessary to push through this period (using the right technique, not abusing the medication) in order to get the desired results.
3. Apply Correctly
Apply the amount of pea-sized on clean and totally dry skin while keeping away from the eyes and lips, then apply your moisturizer after the tretinoin has been absorbed into your skin. “The ‘sandwich’ technique (moisturize-wait-tretinoin-wait-moisturize) may help minimize irritations, especially if you have sensitive/reactive skin.
4. Address Contributing Factors Too
Because excess oil and dirt are some of the factors that cause the appearance of clogged pores, adopting a routine that involves gentle, non-comedogenic cleansers, as well as avoiding pore-clogging cosmetics, could help you in your quest for clearer pores.
5. Protect Your Progress With Sunscreen
One of the factors that causes reduced skin elasticity (hence causing the appearance of pores) is UV damage. In addition to offering protection against tretinoin-related sensitization to the sun, sunscreen would offer protection for your progress.
What Tretinoin Won’t Do for Pores
Of course, it is important to set realistic expectations. The effects of tretinoin do not include:
- An actual change in genetically defined pore size structure – it only makes pores look smaller; the anatomical size remains unchanged
- Visible results within days or just a few weeks – the effects will appear gradually, over several months
- The same effect on all people – while someone with enlarged pores due to sebum and debris accumulation might achieve significant results faster, others, whose enlarged pores are a consequence of long-term sun damage and collagen depletion, will not
- A substitute for healthy skin care practices, such as gentle washing and sun protection
Does the Cause of Your Enlarged Pores Matter?
But there are several reasons why the pores become larger, and some of them may affect the effectiveness of the treatment with tretinoin:
- Pores affected by oily skin: The abundance of sebum causes stretching of the pores and also congestion. In this case, tretinoin works quite well because cleaning and regulation of the sebum are essential for the functioning of the medicine.
- Pores affected by aging and UV damage: With aging and prolonged exposure to UV rays, the levels of collagen and elastin decrease. It causes enlargement of the pores because the skin lacks structural support. In this case, the ability of tretinoin to stimulate collagen production becomes highly relevant, although the results appear slowly in accordance with the timeline of anti-aging properties of the medicine.
- Genetically large pores: There are people who have pores of larger size from the beginning due to the natural skin structure. They usually occur in people with oily skin. In this case, tretinoin is able to make them look better by keeping them clean and supporting the skin around them.
Knowing which group you belong to will aid in having a reasonable expectation because an individual who has pore problems caused by congestion will see results faster than an individual whose pores are mostly affected due to aging skin structure.
Final Thoughts
Tretinoin before and after pore effects are based on scientifically proven dermatology principles, not beauty product advertising. Since tretinoin helps clear congestion and build collagen and elasticity around each pore, tretinoin can actually give you improved pore size results, even though tretinoin does not change the DNA makeup of your pores.
A realistic process to get those results will be a slow one: starting slow, getting through the purge phase, and sticking with the regimen for many months rather than waiting for the instant changes that may be seen in internet videos. Along with using gentle skincare products and daily sunscreen, tretinoin continues to be one of the most research-proven methods available.
Frequently Asked Questions
How long does it take to see pore improvement from tretinoin?
The majority of resources claim that pore-related and texture changes appear after 4 to 6 weeks, and improvement becomes more evident between 2 and 3 months, continuing up until 6 to 12 months as collagen remodeling occurs.
Does tretinoin permanently shrink pores?
No, because pore size is mostly determined by genetic factors. However, what tretinoin does is keep pores unclogged and ensure the elasticity of the skin around them, making them appear smaller visually.
Will my pores go back to looking larger if I stop using tretinoin?
As there is no change in the underlying structure of the pores, stopping the use of tretinoin will probably lead to the eventual reemergence of congestion and lack of firmness, which is one of the reasons why tretinoin is usually taken as a long-term treatment.
Is purging part of getting better pore results?
Yes, for many people, this can be a phase during which increased congestion or even breakouts may occur as a result of faster appearance of old clogs, usually between weeks 2 and 8, before the improvement phase begins.
What strength of tretinoin works best for pores?
It is usually recommended to begin with the lowest concentrations (0.025%), and some studies indicate improvement of photoaged skin pores within a few months of using 0.05% concentration of tretinoin.
