## Overview

Dot & Key Blueberry Hydrate 12% Barrier Boost Serum is a 30ml advanced skincare solution featuring a potent 12% Barrier Boost Complex with 20 active ingredients including 7 ceramides, niacinamide, and hyaluronic acid. Designed to penetrate 10 layers deep, it intensely hydrates, repairs the skin barrier, reduces dark spots and redness, and improves elasticity with a lightweight milky-gel texture suitable for all skin types.

## Description

Formulated with 12% Barrier Boosts Complex, a technology driven by 20 potent ingredients that work together to form an invisible protective layer at the surface level of the skin to repair & protect skin barrier while also making it resilient against external aggressors. It also locks in moisture at deeper layers of the skin to boost hydration (immediate & long-term) & further prevent water loss, thus restoring healthy skin texture & elasticity with a visible plumping effect.

Review: My skin saviour - I honestly didn’t realise how much I had messed up my skin barrier until my skin started reacting to everything. I had been quite careless with the products I was using, so finding this serum at that point felt like such a blessing. It helped get my skin back to its normal, comfortable state. I love how light it feels and how quickly it sinks in without leaving any stickiness. It has been such a good find for me, and I’m really glad I came across it when I needed it most.
Review: I recommend - I am really happy for the purchase. Thanks to desertcart I can order my stuff and get delivery on time and fast 👍👍👍

### ⭐⭐⭐⭐ A good barrier repairing serum
*by B***V on 8 November 2025*

Good product. I had a damaged nd weak skin barrier from using a lot of actives. I was using lot of actives like retinol nd benzoyl peroxide to treat my acne but bcz I had weakened skin barrier, none of them were working nd I had more acne. After I started using this product, my skin calmed down nd reduced acne forming just with 4 uses within 4 days. My skin is a lot more less oily and is becoming better. It's very moisturizing, no oiliness when applied, doesn't clog pores, no scent or fragrance nd doesn't irritate your skin. Overall a good product
