Intelligent Retinol 6TR

Retinol at 0.6% in an anhydrous squalane and safflower base. The middle rung, for skin settled at 0.3%.

Retinol at 0.6% — double the 3TR — in the same oil base of squalane, safflower seed oil and caprylic/capric triglyceride, with vitamin E and BHT keeping the retinol stable.

This is a step up, not a starting point. The convention with a Vitamin A ladder is to finish the tube you are on before you climb, and to climb only if your skin is comfortable where it is. Staying at a lower rung indefinitely is a legitimate place to end up.

Four drops in the evening, phased in over about a month, then nightly. Sunscreen every morning while you are using it.

Made for skin settled on a lower strength of Vitamin A.

Actives: Retinol 0.6%
