Skincare trends come and go, but some products like tretinoin stand the test of time. Right now, tretinoin is having a major moment, with everyone from dermatologists to influencers praising its transformative effects on acne, fine lines, and overall skin health. What sets tretinoin apart from the average fad is the solid body of evidence supporting its benefits. This isn’t just another overhyped product; it’s a dermatologist-approved solution backed by decades of research.
As a holistic nutritionist, I believe skin health goes beyond what we apply topically—it reflects our overall wellness that starts from within. Still, I’m intrigued by tretinoin’s potential when used thoughtfully and holistically. I’m here to break down what tretinoin is, how to use it effectively, its benefits and drawbacks, and how to integrate it into a skincare routine that supports your health from the inside out.
Tretinoin, or retinoic acid, is a synthetic vitamin A derivative. It’s known to be the most bioactive vitamin A derivative, contributing to its efficacy as a skincare treatment. Tretinoin was originally developed as a prescription medication for treating acne, but researchers quickly realized that it also has anti-aging and skin-renewing properties. Tretinoin increases cell turnover, unclogs pores, and stimulates collagen production, making it a versatile tool in dermatology.
Unlike over-the-counter retinol products, tretinoin is much stronger and requires a prescription. While both are derived from vitamin A, tretinoin is pure retinoic acid, meaning it doesn’t need to be converted within the skin to become active. This potency makes tretinoin so effective, which is also why it should be used thoughtfully.
If you’re new to tretinoin, it’s crucial to introduce it into your routine with care. This product can do absolute wonders for your skin, but improper use can lead to irritation and setbacks.
Apply tretinoin two to three times per week to allow your skin to adjust. As your skin builds tolerance, you can gradually increase to nightly use if recommended by your dermatologist. Note that any acne may initially get worse before getting better. This “purging” stage typically goes away after the first few weeks and is only a natural part of the disease process.
Tretinoin is best applied before bed because it increases the skin’s sensitivity to the sun. Always follow up with sunscreen during the day (this is one of my fave skin tints with SPF 40!).
For most people, tretinoin is very drying and can make your skin feel uncomfortably tight. Pair tretinoin with a moisturizer to minimize dryness and support your skin barrier.
Tretinoin works over time. You may experience redness, peeling, and “purging” during the first few weeks. These effects are temporary and part of the process as your skin adjusts. Tretinoin’s evidence-based benefits will be just around the corner for you.
Tretinoin accelerates the natural shedding of dead skin cells, helping to reveal fresher, brighter, healthier skin underneath.
Many studies have shown tretinoin’s efficacy in improving skin texture caused by sun damage and aging. By stimulating collagen production, tretinoin helps to reduce the appearance of fine lines and wrinkles over time, making it a staple anti-aging tool.
Hyperpigmentation can be stubborn, whether caused by sun damage, acne, or aging. Tretinoin promotes an even skin tone by fading dark spots and discoloration.
Tretinoin unclogs pores and prevents new breakouts from forming. Its ability to reduce inflammation also helps in treating acne-prone skin.
With consistent use, tretinoin can give your skin a radiant, youthful glow, making it a valuable addition to long-term skin health.
As I mentioned, you may initially experience irritation, including redness, dryness, and peeling. This phase, though temporary, can be uncomfortable. However, if the irritation persists, check back in with your dermatologist.
Tretinoin increases your skin’s sensitivity to UV rays, making sunscreen an absolute must. Without proper sun protection, you risk sunburn and further skin damage.
Isotretinoin, a chemical similar to tretinoin but different in structure, can cause serious effects on fetal development when taken orally. While topical tretinoin is likely to be safe for pregnancy, it may be best to avoid it overall to reduce the risk of potential birth defects.
Incorporating tretinoin into your skincare routine can be transformative, but its use is most effective when paired with a holistic approach to skin health. Balance is key—while tretinoin works externally to renew your skin, you should also focus on detoxing your life in other ways to support overall wellness. This includes minimizing exposure to environmental toxins, such as harsh chemicals in household products, and prioritizing clean, nutrient-dense foods. A diet rich in vitamins A, C, and E, omega-3 fatty acids, and antioxidants can nourish your skin from within to complement tretinoin’s effects. Staying hydrated, getting enough restorative sleep, and managing stress are equally important in impacting your skin’s health and ability to heal.
By addressing the internal and external factors that affect your skin, you can create harmony between your skincare routine and overall lifestyle, allowing tretinoin to work its magic as part of a balanced, holistic plan.
