What is retinol serum?
Retinol serum is a skin care product that contains retinol, a vitamin A derivative that promotes skin cell turnover and collagen production. These serums work by increasing the rate of skin cell regeneration, improving skin texture, reducing fine lines and wrinkles, and making your skin tone more even. Retinol can also unclog pores, making it beneficial for those with acne-prone skin.
Is it proven to be effective?
Studies have shown the effectiveness of retinol in improving overall skin condition. One study found that skin condition significantly improved after using topical formulations containing 0.15% and 0.3% retinol for 8 weeks. Participants experienced improved skin tone, hydration, and radiance, as well as a reduction in the number of wrinkles and skin discoloration.

How do you apply it?
When it comes to applying retinol, it’s important to start slow and gradually increase your usage. If you’re a beginner, we recommend using a small (pea-sized) amount of a low-concentration retinol product once or twice a week, gradually increasing the frequency as your skin gets used to it. Retinol can increase skin sensitivity to sunlight, so be sure to apply it in the evening on clean, dry skin. For best results, please follow these steps:
Wash your face thoroughly and dry it completely. Apply a pea-sized amount of retinol serum to your face, focusing on problem areas. Gently massage the product into your skin until completely absorbed. Use a moisturizer to minimize potential dryness and irritation. In the morning, cleanse your face and apply a broad-spectrum sunscreen.
If you have sensitive skin, try the sandwich or buffering method. Apply a layer of moisturizer, then a retinol serum, then more moisturizer.
