Does Retinol Cause Cancer? Facts About The Cancer Risk


Retinol, also known as vitamin A1, has become a popular skincare ingredient in recent years. It is known to reduce wrinkles, improve skin texture, and fight acne. However, there have been some claims linking retinol use to an increased risk of skin cancer. In this article, we will analyze if there is any truth to these claims and look at the potential risks and benefits of using retinol.

What Is Retinol?

Retinol is a form of vitamin A naturally found in foods like dairy products, fish, and meat. It is also available in many skin care products as an over-the-counter treatment for acne, wrinkles, and sun damage. 

Retinol And Cancer

Once applied to the skin, retinol gets converted into retinoic acid, which acts as a cell communicator. It boosts collagen production, speeds up cell turnover, and reduces oil production. This makes skin appear smoother, firmer, and more even-toned with diminished pores and breakouts.

What Is The Connection Between Retinol And Cancer? 

There have been some studies linking retinol use with increased skin cancer risk. Here is what the research says:

  • In laboratory studies, retinol has been shown to speed up the growth of tumor cells. It may also hinder apoptosis or natural cell death in UV-damaged skin cells with existing DNA mutations. This can allow damaged cells to proliferate into skin cancer.
  • Long-term exposure to UV rays from the sun causes genetic mutations in skin cells, leading to cancer. Retinol speeds up cell turnover, pushing mutated cells to the surface faster than the body can repair DNA damage.
  • Retinol thins the outer layer of the skin and makes it more sensitive to UV radiation. This may make it easier for UV rays to penetrate deep into the skin and cause genetic mutations.

However, human data directly linking retinol use and skin cancer risk is lacking. Most dermatologists maintain that the benefits of retinol outweigh any unproven cancer risk.

What Are The Potential Risks Of Using Retinol?

Connection Between Retinol And Cancer

While an increased risk of skin cancer is unproven, here are some potential side effects of retinol use:

  • Irritation: Retinol increases skin cell turnover rapidly, which can cause redness, dryness, flaking, stinging, and peeling, especially when starting. 
  • Photosensitivity: Retinol thins the outer layer of skin and makes it more vulnerable to sunburns. Proper sun protection is vital when using retinol.
  • Interactions: Retinol may not be suitable for those on certain acne medications or skin treatments like chemical peels. 
  • Pregnancy/breastfeeding: Oral retinol supplements are not recommended as high doses may cause birth defects. Topical use is likely safe but check with your doctor.

To reduce irritation, limit application to 2-3 times per week when starting retinol and gradually increase frequency. Use a moisturizer to buffer the effects. Avoid excessive sun exposure and always wear broadspectrum SPF 30 sunscreen. Consult a dermatologist before using while pregnant or nursing.

Are There Any Natural Alternatives To Retinol?

For those concerned about potential cancer risks or side effects, some natural retinol alternatives include:

  • Rosehip seed oil – Rich in vitamin A and lycopene, it reduces wrinkles and sun damage.
  • Sea buckthorn oil – With over 190 bioactive compounds, it nurtures compromised skin. 
  • Green tea extract – The antioxidant EGCG may help inhibit tumor growth and protect skin cells.
  • Vitamin C – Boosts collagen production and protects against UV damage when used topically. 
  • Coconut oil – Contains fatty acids to improve skin elasticity.
  • Alpha lipoic acid – This antioxidant protects skin from photo-aging.
  • Genistein – Found in soy, this phytochemical guards skin cells against UV radiation. 
  • Bakuchiol – Derived from the Babchi plant, it mimics retinol without irritation.

While more research is still needed, there is currently no strong clinical evidence proving retinol use increases skin cancer risk significantly. When used correctly under medical guidance, most experts believe the proven anti-aging and acne-fighting benefits outweigh any theoretical cancer concerns. Still, those worried about potential risks may want to explore topical natural alternatives for healthier skin. Moderation, sun protection, and consulting your dermatologist is key if using retinol.


Q: Does retinol make skin thinner?

A: Yes, retinol slightly thins the stratum corneum – the outermost layer of the epidermis. This makes the skin more permeable and effective at absorbing active ingredients. However, retinol thickens the deeper dermal layers by boosting collagen, making the skin healthier overall.

Q: Can you reverse retinol damage? 

A: Most negative effects of retinol like redness, peeling, and sensitivity subside over time as skin builds tolerance. Proper moisturization and avoiding overuse limit damage. For lingering effects, discontinue use and focus on skin repair with gentle cleansers, Vitamin C, and sunscreen.

Q: Is retinol safe to use daily?

A: Retinol dosage should be built up gradually from 2-3 times a week to every other day, then daily use if tolerated well. Start with a low concentration and use only a pea-sized amount. Too much too soon can irritate the skin. Always follow usage guidelines and discuss suitability with your dermatologist.

Q: Can retinol remove acne scars?

A: By boosting collagen and skin renewal, retinol helps diminish the appearance of acne scars over time. Shallow scars or discoloration respond best. Deeper pitted scars may require other professional treatments alongside retinol for significant improvement.
