|Peptide Boost Serum, How To Use It?

A great skincare ingredient, peptide is best known for its anti-aging ingredient, but, in fact, it has several effects more than just anti-aging. 
From improving wrinkles and elasticity to reducing pigmentation, reducing sebum, and moisturizing, peptide has a wide range of effects depending on the type of peptide. 

That's why COSRX mixed 6 different peptides in 「The 6 Peptide Skin Booster Serum」. 
A collection of peptides with different effects can help to use for any skin problem.



「The 6 Peptide Skin Booster Serum」 is a booster serum that is used as the very first step after washing the face to act as a toner. 

The overall effects can be more improved if serum, ample, cream, etc. are followed by after using this peptide product. The several active ingredients including peptide have different ways of benefits for each ingredient, which is why they have more a satisfying effect when they are used together.


Peptide, What Ingredient Can It Be Used With?

While a peptide product can be used alone to get a good effect, COSRX recommends some combinations for even better effect.

▶ Peptide and Vitamin C

Vitamin C is a classic antioxidant that is effective in improving a variety of aging issues, including pigmentation, wrinkles, elasticity, and pores. 
However, even this all-purpose vitamin C can cause skin irritation when it is used more than necessary. 

Peptide, which works on a different principle from vitamin C, is the ingredient that can take effect without irritating the skin. 
Using peptide product with vitamin C product together can bring a great effect to improve various aging issues and complexion.


- After fully absorbing 「The 6 Peptide Skin Booster Serum」 product, use a vitamin C product. It helps reduce vitamin C irritation.


 ▶ Peptide and Retinol 

Retinol is effective in improving elasticity and wrinkles by filling with collagen and elastin, which are reduced due to damage in aging and premature aging, in the skin.
However, excessive use can cause dryness and irritation, so it's not recommended to use more than necessary and to use frequently.

Peptide is the ingredient that can assist this tricky retinol and take effect without irritating the skin.
Using peptide product with retinol product together can bring a great effect to improve damage in aging and premature aging issues.



- After fully absorbing 「The 6 Peptide Skin Booster Serum」 product, use a retinol product. It helps reduce retinol irritation.


▶ Peptide and Snail(Mucin)

Snail(Mucin) is a skin-friendly and beneficial ingredient because it has many ingredients that are similar to those that make up our skin. 
Not only it makes the skin healthy and has an excellent soothing and protective effect, but it is also suitable for using safely on all skin types without causing irritation.

Because peptide also gives a wide range of beneficial effects without irritating the skin, 
Using peptide product with snail product together can change your skin to the best condition.


- After fully absorbing 「The 6 Peptide Skin Booster Serum」 product, use a snail product.


▶ Peptide and Niacinamide

Niacinamide is effective for the treatment of various pigmentation mark and skin problems such as acne. 
There are several steps got through from the formation to pigmentation of melanin in the skin, and niacinamide alone can not stop all of these steps. 
This is also the same for the several steps of having skin problems. 

Peptide is an ingredient that makes up for these parts that niacinamide can not resolve and can take effect in the skin. 
Using peptide product with niacinamide product together bring a great effect to improve pigmentation and skin problems.


- After fully absorbing 「The 6 Peptide Skin Booster Serum」 product, use a niacinamide product.


▶ Peptide and Hyaluronic Acid

Hyaluronic acid, as a natural moisture component of the skin, is a mild ingredient that works well with all skin types and keeps moisturizing. 
Peptide also has a variety of effects without irritating and moisturizes the skin. 
Therefore, using peptide product with hyaluronic acid product together is even more effective for moisturizing the skin.

I absolutely love the AC Collection Calming Liquid Mild. I love that it keeps my skin acne free, but is also super moisturizing. Those two things are hard to find in a single product. It’s refreshing, cooling and you can see results quickly.

I really appreciate this blong on their website. Yes, I originally came to earn points, but I also learnt how to pair there products to be most beneficial to my skin, as well as what each of their products do. I started using their pimple patches after my friend recomended them to me since they came in goof quantity and quality at Walmart. I have been a huge fan since and I recently branched out to their skincare line to see if it could help me care for my skin. I got a set of 4, and used them twice this week and my skin has never felt this soft. So i decided to check out the website, and now I know why my skin has been so soft. I think more skincare brans should have blog sections like this where they accurately explain their products and how to use and pair them.
