Retinol Tri-Active Technology is a blend with a fast-acting retinoid, delayed-release retinol, and a retinol booster for rapid results while still being gentle on skin.

Apply retinol at night after cleansing and toning but before moisturizer. Use every other night, or use 2-3 times per week and gradually increase to nightly use as your skin builds tolerance. Apply SPF 30 or higher in the morning as retinal increases sun sensitivity.

This product has been tested safe for sensitive skin. However, we advise performing a patch test and introducing the serum gradually into your routine, as well as buffering with a moisturizer.

Yes, Retinol Youth Renewal Serum includes added fragrance (parfum) and fragrance components.

Key actives include retinol, hydroxypinacolone retinoate, sodium hyaluronate (hyaluronic acid), ceramide NP, squalane and swertia extract.

Retinoids can be drying for some users. If needed, layer a moisturizer over the serum or use less frequently to minimize dryness.

To reduce irritation, introduce other retinoids or strong actives slowly and consider alternating nights or using buffering steps in your routine.

Yes, this serum is formulated without animal-derived ingredients.

Apply Retinol Youth Renewal Serum to your face and neck, avoiding the eye area. Keep the serum below the orbital bone and away from your lips. For the delicate eye area, use a product specifically formulated for that zone, like Retinol Youth Renewal Eye Serum.

If you're using other strong actives such as AHAs or vitamin C, introduce this serum gradually to avoid irritation. Use your dark spot serum during the day, and retinal/retinol at night. Start by alternating nights with retinal/retinol or reducing frequency until your skin builds tolerance, then adjust based on how your skin responds. Always apply broad-spectrum SPF during the day when using retinoids, brightening, or exfoliating serums to protect skin and prevent new dark spots from forming.
