How This Anti-Aging Serum Benefits And Improves Your Skin

This silky, skin-smoothing anti-aging serum was created by Dr. Sanghoon Park, head of Korea's premier dermatology clinic, ID Hospital. The serum's formula draws inspiration from ID Hospital's in-office treatments to: 


-Target sagging skin, wrinkles, and areas that lack elasticity, including the neck and décolleté. 

-Reduce the appearance of fine lines, wrinkles, dullness, and uneven texture

The key ingredient in the Minus Serum is the brand's Sodium Deoxycholate Complex, which is blended with a blend of Micro-Tingling Spicules to help define and firm the appearance of skin over time.


"Minus Serum was created to sculpt and contour the face, jaw, and neckline so that my clients can now create youthful definition in the face with skincare, instead of contouring with makeup," Dr. Park says of the product.

Private Doctor Minus Serum Reviews

"Great product for dry skin. I use it every day and can say that it’s my favorite serum." - ani4kaaa


"Fantastic! I love that it gave me a firmer appearance in a short time and leaves my skin smooth an radiant every time I use it! A must-have for youthful skin when you want instant results!" - MayaCE


"Phenomenal Product! I've always been skeptical of serums as I have combination skin that tends to get oily throughout the day. Private Doctor Minus Serum is such an incredible product! After the application of this product, I am near oil free all day long. Not needing much of this serum in the slightest and working your fingertips to massage in an upwards motion is key! I thoroughly enjoy the slight tingle I feel from Private Doctor Minus Serum. Not to be alarmed by the word "tingle" as this tingle is quite gentle and relaxing. I am really enjoying this product!" - Victoriabuby


"I have been using Minus serum for about a month 2 times a day and have replaced my other serum with it. I see a noticeable brightening and my skin is softer and smoother since using. Redness and blotchiness is better as well. I love this serum. The only negative is that it is a slight bit tacky but that absorbs relatively quickly." - JenP1982
