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.
Tretinoin should be used for at least 6 months for maximum effect. After two years of continuous tretinoin treatment, there is marked improvement in fine and coarse wrinkles, lentigines (“age spots”) and mottled pigmentation.
The degradation of tretinoin 0.025% in the conventional gel was greater than 83 percent within two hours. In the second light exposure study, in vitro exposure to simulated solar light provided a gradual dose-response effect with tretinoin 0.05% formulated as the micronized tretinoin gel.
Tretinoin expiration
If you are wondering if tretinoin expires, tretinoin products typically have an expiration date of two years after the manufacturing date. After this time, the product may become less effective or even cause skin irritation or other side effects.

Storage. Store in the refrigerator. Do not freeze. Keep out of the reach of children.
Expired retinol loses its effectiveness, turning into a lackluster, gooey substance that does little to help your skin.

The bottom line. Retin-A (tretinoin) is a topical medication that's effective for the treatment of acne, wrinkles, and skin damage from the sun. It starts working within the first few weeks of treatment for acne, but can take 3 to 6 months for wrinkles.

After washing your face, apply a layer of moisturiser. Allow it to dry down for 5-10 minutes. Then, apply a pea-sized amount of tretinoin to your entire face. Allow this to dry down for 5-10 minutes.
The skin on the neck is thinner and more sensitive, so it may not tolerate tretinoin well, causing irritation. However, if you want to address signs of ageing on your neck, you may benefit from using tretinoin there. To avoid irritation, start with a lower frequency on your neck and build up as your skin tolerates it.
Some people may notice that this side effect goes away within a few weeks of use, while others may have flaky skin for up to two months. Regardless of how long it takes to subside, tretinoin peeling is temporary and will go away once your skin gets used to the product.
