What is Retin A, and Where Did It Come From?

Retin A is the brand name for tretinoin, a prescription-strength retinoid derived from vitamin A. It was first introduced in the late 1960s by Dr. Albert Kligman, a dermatologist who discovered its acne-fighting properties while studying treatments for skin conditions. Initially developed and approved to treat acne, Retin A soon caught the attention of researchers and dermatologists for its powerful anti-aging benefits as well.


Today, tretinoin is widely used in both dermatology and skincare. It comes in various strengths and formulations, ranging from over-the-counter (OTC) retinoids to high-strength prescription options for more targeted treatments.


How Retin A Works: The Science Behind the Glow

Retin A is not just another skincare trend—it’s backed by decades of research. Here’s how it works on a cellular level:


Promotes Skin Cell Turnover:

Retin A accelerates the natural skin cell renewal process. It helps shed old, dead skin cells on the surface and replaces them with fresh, healthy cells underneath. This turnover process reduces clogged pores (great for acne) and reveals smoother, more radiant skin.


Stimulates Collagen Production:

Tretinoin boosts the production of collagen, the protein responsible for maintaining skin elasticity and firmness. This makes it one of the most effective ingredients for combating fine lines and wrinkles.


Regulates Oil Production:

By normalizing the function of sebaceous (oil) glands, Retin A helps reduce excess oil, which is a significant factor in acne formation.


Unclogs Pores:

Retin A works as a powerful exfoliant that clears out debris from pores, preventing blackheads, whiteheads, and other types of acne.


Scientific studies have shown that Retin A’s effects go beyond superficial improvements. It literally rejuvenates the skin, promoting healthier skin from the inside out.


What is Retin A Used For Today?

Retin A has a wide range of applications in skincare and beyond. Here are some of its most common uses:

  1. Acne Treatment: Retin A is a gold-standard treatment for acne. It’s particularly effective for comedonal acne (blackheads and whiteheads) and can help with inflammatory acne as well over time.

  2. Anti-Aging: Tretinoin is one of the few ingredients proven to reduce the appearance of fine lines, wrinkles, and hyperpigmentation. It promotes smoother, firmer, and more youthful-looking skin.

  3. Skin Brightening: By encouraging cell turnover, Retin A helps fade dark spots, melasma, and post-inflammatory hyperpigmentation (PIH), leaving the skin more even-toned.

  4. Nail Growth: Fun fact: Retin A has also been explored for its potential to strengthen and promote nail growth.

  5. Other Uses: Tretinoin has been studied for managing conditions such as keratosis pilaris, chronic sun damage, and even stretch marks, although these uses are less common.






Strengths of Retin A: OTC vs. Prescription


Prescription Strengths:

Prescription tretinoin is available in concentrations such as 0.025%, 0.05%, and 0.1%. These higher-strength formulas are often prescribed for stubborn acne or significant anti-aging concerns.


Prescription versions require a consultation with a dermatologist, but online telehealth services now make it easy to get a prescription. We've used and really liked Hers.


Over-the-Counter (OTC) Options:

OTC retinoids, such as adapalene (Differin 0.1%), are milder but still effective for acne and anti-aging benefits. Other popular OTC options include A313 (a French pharmacy favorite) and products from brands like Sunday Riley A+ and our favorite, Senté Bio Complete Serum. Another top pick, though we have not tried it is, Eau Thermale Avène RetrinAL 0.1 Intensive Cream.


Should You Use Retin A?

The answer depends on your skincare goals. Here’s a quick guide:


  • For Anti-Aging: Retin A is one of the most effective ingredients to reduce fine lines, wrinkles, and improve skin texture.

  • For Acne: Retin A can help with blackheads, whiteheads, and mild to moderate acne. However, cystic or severe acne may require additional treatments.

  • For Hyperpigmentation: Retin A is a great option to fade dark spots and improve overall skin tone.


A Word of Caution: Things to Know Before Starting Retin A

While Retin A is a powerhouse ingredient, it’s also known for being drying and irritating, especially for beginners. Here are some tips to minimize side effects:


  • Start Slow: Use Retin A 2-3 times a week to allow your skin to build tolerance. Gradually increase frequency as your skin adjusts.

  • Watch for Signs of Irritation: If you notice redness, peeling, or dryness, take a 2-3 day break and focus on restoring your skin barrier with gentle moisturizers.

  • Skin Cycling: Many people follow a skin cycling routine, using Retin A every third day and alternating with hydrating or exfoliating products on other nights.

  • Not for Everyone: Retin A is not recommended during pregnancy or for individuals with very sensitive or compromised skin. This is due to its potential to affect cell development and increase irritation.
