When it comes to first-generation retinoids, such as tretinoin, the brand can indeed play a role in the effectiveness and tolerability of the treatment. However, the active ingredient is what primarily dictates the pharmacological action, meaning that the core benefits of the medication—such as anti-aging and acne treatment—should remain consistent across different brands that contain the same active ingredient.
First-generation retinoids, like tretinoin, are known for their ability to promote cell turnover, reduce the appearance of fine lines, and improve skin texture. They work by increasing the rate of skin cell turnover, which helps to prevent clogged pores and can lead to clearer skin. While the active ingredient is the same, the formulation, including the base ingredients, preservatives, and other additives, can vary significantly between brands. These differences can influence how well the product is absorbed by the skin, its stability, and its potential for causing irritation.

For instance, some formulations may include additional moisturizing agents or soothing ingredients that can help mitigate the dryness and irritation commonly associated with retinoid use. Others may have a more potent formulation that could lead to increased irritation or sensitivity. Therefore, while the active ingredient is crucial, the overall formulation can affect how your skin responds to the treatment.

If you are using a specific brand like "愛潔膚" (Aijiefu) and finding it effective, it may not be necessary to switch to another brand unless you are experiencing issues such as irritation or insufficient results. If you were to switch to a different brand, it would be wise to monitor your skin's response closely, as you may find that some brands work better for you than others.

Regarding the concern about whether using a non-original brand of first-generation retinoids would negate the anti-aging effects, it is important to note that as long as the active ingredient is the same and the formulation is stable, you should still experience the benefits associated with retinoid use. However, if the formulation is significantly different, it could impact how effectively the retinoid works for your skin type.

In conclusion, while the active ingredient in first-generation retinoids is the primary factor in their effectiveness, the specific brand and formulation can influence the overall experience and results. If you are satisfied with the results from your current product, it may be best to continue using it. However, if you are considering trying a different brand, consult with a dermatologist to discuss your options and ensure that you choose a product that aligns with your skin's needs. Always remember to introduce new products gradually and monitor your skin for any adverse reactions.
