What is Tretinoin?

As mentioned above, Tretinoin is a topical derivative of vitamin A that is commonly used to treat acne and skin aging. [R]

In its active form as all-trans retinoic acid, tretinoin exerts its effects by binding to retinoic acid receptors located inside skin cells. This binding stimulates gene transcription and cell signaling pathways, ultimately triggering increased skin cell turnover, normalizing disordered growth, and reducing inflammation. Tretinoin could be one of the active ingredients of certain topical treatment that treats acne.

More specifically, tretinoin, as a topical treatment, works by speeding up cell division and shedding of the outer layers of the skin. This makes it effective for clearing out pores and preventing new acne lesions from forming. The increased cell turnover also means fresher, younger-looking skin cells come to the surface more rapidly. Over time, fine lines and uneven pigmentation diminish as healthier smoother skin is revealed.

In addition to clearing up acne vulgaris, tretinoin has demonstrated efficacy against photoaging changes like wrinkles, dark spots, and rough texture induced by sunlight exposure over one’s lifetime. It accomplishes this by directly reversing abnormal growth patterns in skin damaged by UV radiation. It also seems to stimulate collagen production for firmer, more resilient, and healthy skin.

Possible Benefits of Tretinoin Cream

Repair sun-damaged cells

A double-blind, vehicle-controlled study published in the Journal of the American Academy of Dermatology in 1993 demonstrated that using tretinoin (0.05%) for photoaged skin resulted in the formation of granular layers and thinning of the stratum corneum. Additionally, epidermal pigmentation was significantly reduced after using the topical tretinoin. These results show that tretinoin repairs some damage from long-term sunlight exposure by normalizing keratinization and epidermal pigment. [R]

A later study published in Clinical Interventions in Aging 2007 confirmed tretinoin’s effects on photoaged skin through a trial involving mexametrix gel containing 0.05% tretinoin. After just 8 weeks, researchers observed clinically visible reductions in fine wrinkling, dyspigmentation, pore size, irregular pigmentation, and overall improvement in the appearance and texture of photodamaged skin (Creidi et al., 2007).

Therefore, multiple clinical trials actively demonstrate tretinoin’s ability to regenerate sun-damaged skin cells in part by promoting rapid cell turnover, displacing dysplastic cells, and resetting abnormal pigmentation caused by UV radiation over time. When test subjects consistently apply tretinoin topically, research indicates it can significantly repair and rejuvenate the epidermis altered by decades of sunlight.

Reduce fine lines and wrinkles

A randomized, double-blind, vehicle-controlled clinical trial conducted in 2006 actively demonstrated tretinoin’s ability to reduce fine wrinkles. Researchers treated photodamaged skin on the face and upper neck with either 0.1% tretinoin emollient cream or a vehicle cream for up to 12 weeks. They found tretinoin significantly improved fine wrinkling around the eyes (crow’s feet) as well as creases around the mouth and cheeks compared to control areas. [R]

Additionally, Varani et al. actively showed in a 2000 medical article in the Journal of Investigative Dermatology that using 0.1% tretinoin for 4 months induced collagen synthesis and enhanced levels of collagen-degrading matrix metalloproteinases around wrinkles. These effects ultimately led to measurable clinical improvement in periorbital and perioral wrinkles, likely due to collagen remodeling and repair of dermal structures. [R]

Improve skin texture and tone

A randomized, vehicle-controlled trial conducted in 1988 actively demonstrated tretinoin’s effects on collagen production, acne breakouts, and skin texture improvement. Researchers treated photodamaged forearm skin with either 0.1% tretinoin cream or vehicle control for up to 12 months. Biopsy results showed 0.1% tretinoin actively increased collagen synthesis by approximately 80% relative to control skin after 3-6 months of treatment. Additionally, clinical examination revealed significant improvements in fine wrinkling, skin smoothness, and overall texture in tretinoin-treated areas. [R]

Therefore, this landmark study provides evidence that topical tretinoin actively signals new collagen formation leading to measurable differences in skin texture, smoothness, and tone. By thickening the dermis and stimulating the repair of damaged fibrous structures in aged skin, tretinoin can actively improve tactile roughness as well as visible texture and skin quality, especially in areas chronically exposed to sunlight over time.

Prevents follicular plugging

Multiple clinical studies have actively demonstrated that consistent use of topical tretinoin improves follicular plugging and congestion by accelerating epidermal turnover. A trial conducted by researchers in 1993 treated photodamaged skin with 0.05% tretinoin cream for up to 50 weeks. Biopsies taken at 16 weeks showed tretinoin actively decreased compact hyperkeratosis and epidermal thickness while increasing keratinocyte proliferation. These effects are indicative of enhanced desquamation and cell shedding which actively clear pore-clogging debris. [R]

Additionally, a more recent 12-week study published in 2005 found that 0.05% tretinoin gel applied once nightly actively reduced non-inflammatory closed comedones by 51% after 12 weeks of treatment. By promoting rapid maturation and shedding of skin cells that otherwise would build up inside follicles, tretinoin is able to actively prevent plugging problems associated with blackheads and whiteheads.

In summary, consistent topical tretinoin actively normalizes excessive keratinization in the follicular epithelium and increases cell turnover through receptor-mediated signaling cascades. Together, these mechanisms actively reduce plugging, congestion, and visible signs of closed comedones over time.

Reduces inflammation

A meta-analysis published in the Journal of Clinical and Aesthetic Dermatology in 2011 reviewed evidence for tretinoin’s effects on acne-related inflammation. [R]

Researchers identified five key mechanisms that allow topical tretinoin to actively combat inflammation related to its anti-aging properties:

1. Downregulation of inflammatory markers like IL-1α
2. Increased toll-like receptor 2 expression to reduce inflammation
3. Induction of immunosuppressive signaling cascades
4. Inhibition of AP-1 transcription factor activation
5. Suppressed activation of inflammatory C5 component

Accelerates new skin cell growth

Tretinoin, a derivative of vitamin A and a potent retinoid, offers a multitude of benefits for the skin due to its ability to increase epidermal cellular turnover.

A study published in the Journal of Drugs in Dermatology in 2018 titled “Tretinoin: A Review of its Anti-inflammatory Properties in the Treatment of Acne” emphasized the role of tretinoin in modulating cellular differentiation and proliferation. It highlighted how tretinoin influences the turnover of epidermal cells, promoting the shedding of old cells and stimulating the growth of new cells, resulting in smoother and clearer skin. [R]

Another notable study, published in the Journal of Investigative Dermatology in 1996, investigated the impact of tretinoin on skin aging. The findings indicated that tretinoin promoted collagen synthesis and increased the turnover of epidermal cells, contributing to improved skin structure and appearance. [R]

How Does Tretinoin Work?

Tretinoin accelerates skin cell turnover by binding to receptors (retinoic acid receptors) inside skin cells and altering gene transcription. This speeds up the cell cycle, causing faster proliferation and shedding of epidermal cells. Essentially, it signals the epidermis to regenerate itself more rapidly.

Under normal conditions, it takes around 40-56 days for the skin to renew its outer layer through complete turnover of epidermal cells. Tretinoin drastically shortens this cell life cycle to just a few days. Older, damaged cells are pushed out faster as younger cells divide and move into the lower layers.

In acne, this rapid cell turnover has multiple benefits – it prevents dead skin cells and accumulated debris from clogging hair follicles while clearing existing comedones. It also reduces inflammation by increasing cell-mediated immunity and directly inhibiting inflammatory mediators.

For photoaged skin, quicker replacement of epidermal cells erases fine lines, evens out dyspigmentation, and replaces abnormal, dysfunctional cells with healthier ones. Increased epidermal proliferation is also associated with greater collagen production in the dermis underneath.

In summary, by binding to receptors inside skin cells and switching on genes that accelerate cell turnover, tretinoin is able to treat acne, reverse signs of sun damage, and improve the skin’s overall youthful appearance.

Safety and Side Effects of Tretinoin

Generally Safe

Based on studies, Tretinoin shows potential in treating acne and skin aging, but it commonly causes significant irritation, especially when first starting treatment. It is generally safe to use. Today, certain manufacturers mix tretinoin with hyaluronic acid for better results.

Typical Side Effects

Typical side effects include redness, dryness, peeling, itching, and a sunburn-like sensation on the skin. These localized reactions reflect increased cell turnover in the epidermis. It may take 2-6 weeks for the skin to adjust and irritation in subjects to subside.

Additionally, by thinning the stratum corneum, tretinoin makes skin more vulnerable to UV damage from sunlight exposure. Diligent daily sunscreen use is imperative when using this medication to avoid increased photosensitivity.

Frequently Asked Questions

Do you need a prescription to buy Tretinoin?

Yes, you need a prescription from a doctor or dermatologist in order to purchase tretinoin products. Tretinoin is a prescription-medication retinoid drug that is regulated as a medical treatment for certain skin conditions. It is not available over-the-counter without a valid prescription. This helps ensure proper medical oversight for an effective yet potentially irritating medication. Behemothlabz does not sell Tretinoin.

Why is Tretinoin considered a retinoid?

Tretinoin is considered a retinoid because it is a chemical compound derived from vitamin A. Specifically, tretinoin consists of an active form of vitamin A called all-trans retinoic acid.

Retinoids refer to a class of compounds that are structurally related to vitamin A. All retinoids have a common molecular backbone structure and exert cellular effects by binding to retinoic acid receptors inside cells. These receptors regulate gene expression and control processes like cellular growth and differentiation.

Are there alternatives to tretinoin?

Topical retinoids such as tazarotene and trifarotene can be used as an alternative to tretinoin, however, just like tretinoin, these prescription retinoids are only sold with a doctor’s prescription.

Summary

Tretinoin is a topical derivative of vitamin A which belongs to a class of compounds called retinoids. Its efficacy as an acne and anti-aging treatment comes from its ability to accelerate the turnover of skin cells. By binding to receptors within epidermal cells, tretinoin stimulates gene transcription that causes rapid cell proliferation and shedding. This replaces older, damaged cells with healthier ones and prevents dead skin buildup that clogs pores.

Consistent application results in comprehensive skin renewal – fine lines and uneven pigmentation fade as smoother, clearer skin surfaces. Tretinoin also possesses direct anti-inflammatory properties to reduce acne erythema. However, the irritation potential is high, and patients often endure weeks of dryness, peeling redness, and sensitivity as the skin adjusts. Due to increased photosensitivity, diligent sunscreen use is critical.

While challenging to initiate, once ramped up slowly under dermatology guidance, tretinoin safely and effectively treats both acne vulgaris and chronological aging. It kickstarts cellular processes that cannot be stimulated to the same extent by other topicals. With proper medical oversight, tretinoin’s dramatic improvements in skin texture, tone, and clarity make it the gold standard treatment for photoaging and acne management.
