Is collagen serum better than retinol?

The choice between collagen serum and retinol depends on your personal skin type, sensitivities, needs, and goals, according to an article by Good Glow. Retinol is ideal for active acne and prevention, while collagen should be considered for skin repair and maintenance (as well as hair and nail growth). However, an article by Beauty Way Mag suggests that retinol is stronger and better to use than collagen serum because it can penetrate deep into the dermis, unlike collagen serum. The ability of retinol to penetrate the skin helps the skin to turn over cells on time, to the end that your skin is smooth and young-looking. Ultimately, the choice between collagen serum and retinol depends on your individual skincare concerns and goals.

How often should you use a collagen serum?

I would recommend using a collagen serum once a day. Hasan Benar, MD , a dermatologist and aesthetic doctor, says you could even use it twice daily for quicker results.
