Tretinoin timeline: Weekly progress

What are the results of tretinoin after 2 weeks?

During the first two weeks of using tretinoin, your skin undergoes several changes as it adapts to it. These changes are often referred to as the “retinization” process which typically consists on the following:

Skin cell exfoliation

Tretinoin stimulates the turnover of skin cells, a process known as desquamation and exfoliation. This consists of shedding the outermost layer of dead skin cells and replacing them with new ones. By promoting this process, tretinoin helps to reveal fresher, younger skin cells, resulting in a smoother complexion and improved skin tone¹. 

Dryness and irritation

Many users experience increased dryness, redness, sensitivity, or even a slight increase in acne breakouts during the initial weeks of tretinoin use. This skin reaction is often referred to as the “tretinoin purge” and is a temporary reaction as the skin adjusts.

Stimulation of collagen production 

Tretinoin stimulates the production of collagen, a key protein responsible for maintaining skin’s firmness and elasticity. This process begins in the early stages of tretinoin use, although the visible effects may not be apparent until later².

Reduction of oil production in the skin

Tretinoin has the ability to decrease the growth and reproduction of sebocytes, which are the specialized cells found in sebaceous glands responsible for producing oil in the skin. Additionally, it also helps suppress the production of sebum itself³.

Activation of skin proteins and enzymes 

Tretinoin activates various skin proteins and enzymes that play crucial roles in skin repair and rejuvenation⁴.

It is important to note that the initial side effects like dryness, flaking, and increased sensitivity are common and usually temporary. To minimize tretinoin irritation, you can read our Dermatologist’s Guide: How to use tretinoin  

To minimize discomfort during this adjustment period, it is recommended to start with a lower strength of tretinoin and gradually increase frequency and potency under the guidance of your online dermatologist. Apply tretinoin only at night as it gets inactivated in the presence of light. Moreover, due to its extreme photosensitive potential, it is not advisable to ever apply it in the daytime.

Additionally, using a gentle moisturizer with niacinamide and applying sunscreen with a high SPF on a daily basis (even during winter) are essential to help maintain skin hydration and protect against potential sun sensitivity.

What are the results of tretinoin after 6 weeks?

After 6 weeks of using tretinoin, your skin typically goes through further improvements and adjustments as it continues to adapt to the medication. Here are some changes you may observe at this stage:

Smoother skin texture

One of the noticeable effects of tretinoin after 6 weeks is a smoother skin texture. As tretinoin continues to promote cell turnover, and inhibit collagen breakdown, the surface of your skin becomes more refined, with fewer rough patches⁵.

Reduced acne breakouts

If you are using tretinoin to treat acne, you may see a reduction in the frequency and severity of breakouts. Tretinoin helps unclog pores, which can lead to fewer pimples and blackheads⁶.

Even skin tone

Tretinoin can contribute to a more even skin tone by fading hyperpigmented areas, such as acne scars and sunspots. This can lead to a brighter and more uniform complexion⁷.

If you are interested in reducing hyperpigmentation, you could consider a formulation with tretinoin and hydroquinone (like Tri-Luma) or tretinoin with azelaic acid to get faster results. 

Decreased skin sensitivity

While you may have experienced initial sensitivity and redness during the first few weeks, after 6 weeks, your skin often becomes less sensitive to tretinoin. It is important to continue using a gentle skincare routine and sunscreen to minimize potential irritation.

Improved overall skin health

Tretinoin contributes to the overall health of your skin by encouraging the production of new collagen and promoting skin renewal. This leads to a fresher, more youthful appearance.

What are the results of tretinoin after 3 months?

If you consistently use tretinoin for three months you can expect to have a reduction in acne breakouts, smoother and firmer skin, a more even complexion, enhanced skin elasticity and more refined pores. 

Considerable reduction of acne breakouts

After three months of daily use, tretinoin often provides significant relief from acne. It helps to unclog pores, reduce inflammation, and prevent new acne lesions from forming. Your skin is likely to appear clearer with fewer pimples and blackheads.

Smoother and firmer skin

Tretinoin continues to stimulate collagen production, which can lead to a smoother and firmer skin texture. Fine lines and wrinkles may become less pronounced, and your skin may appear more youthful and supple.

Improved skin tone

Hyperpigmented areas, such as acne scars and sunspots, may continue to fade, contributing to a more even skin tone. This can result in a brighter complexion and reduced discoloration.

Enhanced skin elasticity

Tretinoin’s collagen-boosting effects can enhance the elasticity of your skin, making it more resilient and less prone to sagging.

Refined pores

Over time, tretinoin can help minimize the appearance of enlarged pores, by stimulating collagen production and unclogging pores. It helps in giving your skin a smoother and more refined appearance.

Reverse photodamage

With 12 weeks of consistent tretinoin usage, you’ll start seeing a significant improvement in the skin damage caused to the skin by sun exposure. There is a reduction of sun-induced yellowish thick appearance of the skin, sun spots, coarse wrinkles,  and uneven pigmentation due to sunburns.

What are the results of tretinoin after 1 year?

After 12 months of using tretinoin consistently, your skin will continue to experience a range of improvements and transformations. 

Significant reduction in fine lines and wrinkles

The long-term use of tretinoin often leads to a substantial reduction in the appearance of fine lines and wrinkles. The stimulation of collagen and elastin production and continuous skin renewal contribute to smoother, firmer skin. It also helps in increasing the thickness of skin and reducing the appearance of age-related translucency and sagging of skin⁸.

Minimized acne scarring

If you have been using tretinoin for acne scars, the 12-month mark is a significant milestone. Tretinoin’s consistent use can result in the fading of acne scars, making them less noticeable and contributing to an improved overall complexion⁹.

Enhanced skin firmness

The collagen-boosting properties of tretinoin will help you maintain skin firmness and elasticity. Your skin may appear more toned and resilient, and sagging is less likely.

Refined pores

Studies show that tretinoin can reduce the appearance of large pores due to the increased cell turnover. Pores may appear smaller and less noticeable, giving you a smoother texture. 

Radiant skin tone

Persistent hyperpigmentation, such as sunspots and post-inflammatory hyperpigmentation, is likely to fade further, resulting in a more even and radiant skin tone.

Ongoing skin health

Tretinoin supports the overall health of your skin by encouraging continual cell turnover and renewal. This contributes to a refreshed and youthful appearance.

The takeaway

According to Dr. Mohta, to maintain the benefits you achieved over the past year, it is crucial to continue using tretinoin as part of your long-term skincare routine. You can safely use tretinoin long-term. Research has shown no negative effects even with 2-4 years of usage.¹¹

The time taken for tretinoin to show effects also depends on the severity of your skin issues as well as the formulation and strength of tretinoin you are using. 

Many people wonder if the benefits of tretinoin persist in the long term. The answer is yes, but it requires the consistent use of tretinoin. Since your skin renews itself every month, discontinuing tretinoin for a month will require an adjustment period when you resume its use. The frequency of tretinoin use will also impact the lasting advantages.

Consistency is key, as discontinuing use may result in a gradual return to previous skin conditions. If you want to ensure you get tretinoin at the best price, read our Tretinoin coupon guide.
