Beware of the "miracle drug" Retinol.

Retinoids are divided into three generations, available in both oral and topical forms. Depending on your skin problems, you should choose the appropriate generation.

For acne, Tretinoin, Adapalen, and Isotretinoin (oral) are recommended. For melasma and hyperpigmentation, Tretinoin is the best choice. For anti-aging, Tretinoin, Tazarolene, and Retinol (often mistakenly considered all retinoids) are recommended.

Among them, Retinol stands out and is the most popular because it is the most potent ingredient in over-the-counter retinoid products.

To better understand Retinol, let's first learn a little about aging. Aging includes both intrinsic and extrinsic aging, primarily caused by sunlight. Photoaging of the skin is related to the activity of free radicals caused by UV rays.

Through free radicals, UV rays reduce collagen synthesis. Retinol acts on the skin by binding to receptors in the cell nucleus, promoting skin cell regeneration from deep within the epidermis and boosting collagen production, resulting in firmer, younger-looking skin. Retinol also exfoliates the skin's surface, making it appear brighter. The skin will be renewed, wrinkles will be reduced, and skin tone will be improved.

Although Retinol offers numerous benefits for the skin, it can cause irritation, especially in those with sensitive skin. By exfoliating the top layer of skin, Retinol also increases the risk of sunburn. Therefore, when using products containing Retinol, you need to be aware of the following to ensure effectiveness and avoid side effects:

1. Start with a low concentration: When using Retinol for the first time, you should start with a product that has a lower concentration, then gradually increase it as your skin adapts.

2. Use the product at night: Retinol can make skin more sensitive to sunlight. You should use products containing retinol in the evening before bed and use sunscreen during the day to avoid the harmful effects of UV rays.

3. Use the right amount: You should use the product in moderation as directed by the manufacturer, avoiding excessive or frequent use (usually twice a week).

4. Combine with moisturizing products: Retinol can dry out the skin, so you should use additional moisturizing and restorative products to keep your skin soft and hydrated.

5. Avoid combining with irritating products: Do not use Retinol at the same time as AHA, BHA, or vitamin C products.

6. Do not use during pregnancy: Retinol is believed to potentially harm the fetus, so you should avoid using products containing retinol while pregnant or breastfeeding.
