Why You’ll Love It
For first-time users, Kiehl's popular retinol serum is now available in a 14-day trial size! This aggressive and protective retinol*1 serum addresses complex adult skin concerns in one bottle. It leaves skin bouncy, firm, and poreless.*2 While retinol*1 is widely regarded for its numerous beauty benefits, it can often cause skin irritation. Through extensive research, we've developed a unique formula that makes retinol*1 suitable for sensitive skin*3. Kiehl's Micro Retinol*1 works gradually, delivering the same benefits without irritation. It also contains niacinamide*4 and peptides*5 for aggressive effects, and ceramides*6 and hyaluronic acid*7 for protective effects. Its multi-faceted formula addresses the increasingly noticeable pores around the cheeks*2, shadows under the eyes and around the corners of the mouth*8, and fine lines caused by dryness*9, all of which appear with age. It also deeply moisturizes and supports the skin's barrier function*10. *Limited to one time per person *Please refrain from using if you are pregnant or breastfeeding, or have just had waxing or laser treatment. *Please read the instructions and precautions carefully before use. *1 Skin conditioning ingredients *2 Skin smoothness *3 This does not mean that skin problems will not occur in all people *4 Skin conditioning ingredients *5 Acetyl dipeptide-1 cetyl (skin conditioning ingredient) *6 Ceramide NP (moisturizing ingredient) *7 Hyaluronic acid Na (moisturizing ingredient) *8 Reduces loss of firmness and uneven texture *9 Reduces the appearance of fine lines caused by dryness (efficacy evaluation test completed) *10 Stratum corneum
How to Work It Into Your Routine
For daily skincare, apply 2-3 pumps to your entire face after toning with lotion, then moisturize with your regular skincare routine, such as cream or lotion. We recommend using it at night. When using in the morning, be sure to apply sunscreen. Avoid the upper eyelids and lips, where the skin is particularly thin, and avoid contact with eyes. It can also be used on the neck and décolleté, using one pump as a guide. For customers trying retinol* for the first time: Start with a small amount every other day for approximately 1-2 weeks to allow your skin to become accustomed to the retinol*. Thereafter, use once daily, monitoring your skin's condition. If you are concerned about irritation, we recommend using it after a cream. Please read the instructions and precautions carefully before use. *Retinol (skin conditioning ingredient) *Do not use during pregnancy or breastfeeding. *Avoid use on particularly sensitive skin or immediately after laser or wax treatment.
