Retinol Evening Renewal Serum

Gently renew the surface of your skin each night for improved skin tone, fewer lines, and less visible pores. 


If you can use retinol, you should. It’s one of the most lauded ingredients in skin care, backed by decades of impressive study results. Dermatologists recommend products containing this powerfully effective vitamin A derivative more than any other anti-aging topical, because it addresses such a widerange of age-related and environmental damage to the skin.

Size: 1 fl oz

What It Does
  • Reduces lines and wrinkles
  • Firms and restores lost volume and elasticity
  • Minimizes scarring and stretch marks
  • Helps to lessen the appearance of enlarged pores
  • Smoothes uneven tone and texture
  • Repairs and protects skin from environmental damage
  • Provides long term protection from skin aging
Who It’s For

Most skin types (this product may be too active for some extra sensitive skin types) seeking anti-aging and rejuvenation from past damage to the skin.

How It Works

Retinol Evening Renewal Serum delivers 1% retinol in a curated blend of anti-aging actives. It’s a formula that proves less can truly be more. Prescription-strength retinol can be irritating, requires a doctor’s visit, and usually does not come with other beneficial ingredients.

Rather than a one-dimensional, high dose retinol product, this unique serum pairs just the right amount of retinol with other dermatological powerhouse ingredients.  Hyaluronic acid and ferulic acid maximize results and minimize the potential for sensitivity in most skin types. This serum also packs two B vitamins, B3 (niacinamide) for hyperpigmentation and inflammatory conditions like acne, and B5 for moisture retention and clarifying acne-prone skin.

These active ingredients, paired with a results-optimizing concentration of retinol, make this serum a must-have in your anti-aging regimen.

How To Use

Apply to face, neck and chest once daily in the evening. 


Water, Hamamelis Virginiana (Witch Hazel) Distillate, Glycerin, Panthenol, Niacinamide, Hyaluronic Acid, Retinyl Acetate, Ferulic Acid, Caprylyl Glycol (and) Phenoxyethanol (and) Sorbic Acid

Helped Heal My Skin

I went through a period of time when I was getting terrible cystic acne. After getting it under control, I was left with terrible scaring all over my face. KRS Retinol Evening Renewal Serum has been essential in healing my skin. A little goes a long way with this product and I can see the the difference in my skin!


I started using the Retinol Evening Renewal Serum six weeks ago along with the Salicylic Cleanser. I was really impressed when Kate Ryan guided me towards starting slow with the products, cleanser first then adding on once I felt it out. They could have easily suggested a full regimen but instead noted the high quality ingredients and potency to their formulations and encouraged me to slowly introduce my skin for best results. Overall my skin is brighter and smoother. I'm no longer breaking out weekly like I had before, my pores seem less noticeable and my makeup goes on so much smoother. Excited to see more changes as time goes on as well as trying more products. Packaging was so well done and the little note was a sweet touch.


I've been using KateRyan skincare about 5 months, and my skin feels wonderful, less lines visible on the forehead and around the eyes. I had collagen injections about 4 years ago and my face and skin felt fuller and smoother, but that only lasted about 3 years. Since being introduced to the vitamin c serum and the collagen booster serum, my skin and face are almost back to the fullness and smoothness I experienced with the injections, which by the way are painful and expensive. I'm very happy with all the products, DMAE serum, retinol serum and even the cleanser, which I wasn't crazy about at first, but have definitely changed my mind! Keep doing what you're doing, I'm a fan!


This product is amazing! I could tell a difference the next morning after using this. I have rosacea, so I was hesitant about using a product with Retinol. But not being in my thirties anymore, I felt like I should be using something. This is gentle but effective. It's nice that you don't need a lot either. This definitely changed the appearance of my skin!


Retinol serum arrived promptly and well packaged. I have used the product for several weeks and have had excellent results with skin toning. I will definitely buy again.
