It's like the GPS for your retinol journey. Always check the expiration date mentioned on the box. Typically, retinol products have an expiration date of 6 to 12 months after opening.
Shelf life after opening: Once opened, tretinoin typically lasts 6 to 12 months, but factors like light, temperature, and humidity can affect its stability and effectiveness.
How long that lasts will depend on how much skin is affected and how well the application instructions are followed. The maximum daily dose, however, is one gram, so a 30-gram tube should last at least 30 days, if not longer.
It depends heavily on use. In a closet, the tubes will last forever, of course. For practice in a bedroom a couple of times a week at modest volumes, you'll probably get five to ten years out of them.
When you open an OTC or prescription retinol product like Tretinoin or Retin-A, its effectiveness begins to diminish as time passes. Generally, the retinol expiration date will fall between 6 to 12 months after opening, although this can vary depending on the formulation, packaging, and storage conditions.
When it comes to expiration dates, Retinol A and Retinols typically have an expiration date of two years after the manufacturing date. After this period, both products may become less effective, and cause skin irritation or other side effects.
Retinol can help improve the skin's firmness, which may help the skin appear “tighter.” However, topical medications (including retinol) can only treat the outer layers of the skin; they cannot address loose or sagging skin due to age-related changes in the underlying support structure of the face.
In spite of what you've read online, retinol products don't need to be refrigerated. Retinol and other retinoids, like many other antioxidants, are sensitive to light, temperature and air. However, stashing your retinol or retinoid product in the fridge isn't the solution to these ingredient challenges.

In general, the recommended age to start using retinol is between 20 and 25.
Tretinoin vs. retinol
Tretinoin is a retinoid available by prescription only. It's been used for decades to treat acne and signs of premature aging from sun exposure (photoaging). It's stronger than the retinol you can buy over the counter, so it may work faster.

It's the number of days or months a medication will last if taken as prescribed. The most common days' supply are for 30 and 90 days. Not all insurance plans will cover a 90-day supply. But you can always ask your prescriber for a 90-day supply, which can sometimes save you money.
Retinol: Apply a pea-sized amount of retinol to your face. If you're new to retinol, start with a lower concentration and gradually increase as your skin builds tolerance. Wait: Allow the retinol to absorb into your skin. Waiting 20-30 minutes can reduce the risk of irritation.
Anti-aging products with ingredients like retinol, glycolic acid and vitamin C can break down quickly and typically last nine months to one year, depending on how they're dispensed. Opt for vacuum-sealed products in air-tight pump bottles for a longer lasting product.
“The symptoms related to tretinoin purging typically involve acne breakouts, severe skin dryness and peeling, redness and irritation, but it is important to know that this phase is temporary and once it's over, the skin will generally begin to improve, and you will be able to see the positive effects.
Retinol can also mitigate the production of tyrosinase, an enzyme integral to the formation of melanin. This preventive mechanism can decelerate the onset of new hyperpigmented spots – which might be why it has been touted as THE skincare ingredient for treating skin conditions like hyperpigmentation and melasma.
