Latest Beauty Buzz - Top Tips for Firming + Tightening Sagging Skin with DMAE and Collagen

Question: I am looking into the Collagen Booster Intense Repair Serum and the 4% DMAE Firming Serum. What is the difference between the two of them? They both say they firm and tighten the skin. Do I need both? 

The short answer is a resounding, YES, here's why:

DMAE in skincare is getting a lot of buzz recently, and for good reason.

Although it's an obscure ingredient for many, it has actually been around for decades, including use as a skincare topical for toning, tightening, lifting and improving elasticity. Collagen is a protein that is more commonly known, especially for its overall healthy benefits for skin, bones, and connective tissue. We’re often asked if you need both DMAE and Collagen for firming, plumping, tightening and elasticity - the answer is yes because they work differently, each role vitally important to youthful skin. 

Kate's DMAE and Collagen Booster Serums both firm and tighten the skin - the difference is in the action of the actives.

Think of your skin in terms of a mattress – you need the structural frame and springs and also the filling that makes it full and firm - that's where collagen and elastin come in. Let's talk more about that here....

If we care about skin aging and reversing the aging process, we must care for our collagen! 

When we talk about skin aging, we are mainly talking about collagen, or lack of it. Collagen peptides are the main structural component of the skin, acting as the filler. Collagen makes up about 70% of skin mass. Baby skin is so plump and taut because collagen and elastin are abundant. As we age, we lose about 1% per year which is why we notice a decline in firmness and tone. Our skin becomes thinner, and wrinkles start to appear. 

By supplying the topical building blocks for collagen and protecting the structure of collagen and elastin, you are shielding your skin from future damage and aging. We recommend applying Collagen Booster Intense Repair Serum at night to take advantage of the restful overnight period while our skin is doing its' important reparative work. A moisturizer can be applied as a last step as needed. 

A lot of skin aging and lack of tone is the result of oxidative stress. A big part of the battle against aging is protecting skin from the free radical damage we’re exposed to every day. All KRS products contain antioxidants -- a vital part of any healthy skincare routine. 

DMAE is an excellent active for more immediate firming, especially for sagging skin.

DMAE works differently from the actives in Collagen Booster, as an ideal partner in the process of firming, toning, and tightening skin. DMAE works to boost acetylcholine (ACH). ACH degrades over time in large part due to oxidative stress from free radicals, and just the natural aging process. ACH is a natural chemical messenger in our body that signals muscle contraction. As we age, and the supplies of ACH decrease, we start to see sagging and lack of firmness. By supplying DMAE topically, in simple terms, we are sending our skin messages to be firmer and tighter. The results of DMAE and Collagen are similar, but with different mechanisms of action - both very important. 

How to use DMAE Serum and Collagen Booster Intense Repair Serum in your daily skincare routine:


Step 1: Cleanse using a gentle cleanser.

Step 2: Apply DMAE Serum to clean dry skin on face, neck and chest. 

Step 2 (optional): Many of our clients use a daily Vitamin C Serum. You can apply a Vitamin C Serum either before or after your DMAE Serum. 

Step 3: Moisturize as needed. 


Step 1: Cleanse using a gentle cleanser. 

​Step 2: Apply Collagen Booster to clean, dry skin on face, neck and chest. 

Step 3: Moisturize as needed.
