## How it works

Hyper Retinol EX 1.0 Serum is Isntree's concentrated serum (20ml). Niacinamide sits in the formula as the brightening and barrier workhorse of the routine, the same B3 vitamin dermo-cosmetic protocols reach for when a complexion looks dull, blotchy or prone to visible redness after cleansing. Bakuchiol is a plant-derived vitamin A alternative formulated for skin that wants a texture-renewing routine without the dryness a stronger resurfacing ingredient can bring, and it layers easily alongside other actives. The concentrated texture sinks in without a greasy residue, leaving skin feeling smoothed and hydrated without a sticky after-feel. It sits in a Korean routine as the treatment step, best layered after essence and before a moisturizer.

## How to use

1. Use the Hyper Retinol EX 1.0 Serum after toner and before moisturizer, in the evening.
2. Take 2 to 3 drops on the palm of your hands and gently pat it on your skin for maximum absorption. Apply the serum at night, after cleansing on a dry skin, before your moisturizer. For sensitive skin, test with a small amount before using it on your face.
3. Toner first so the surface is damp, then this, then about a minute before your moisturizer goes over the top.
4. Twice a day, every day. Do not stack it with a second serum of the same kind; two hydrating serums in one routine do the work of one.

## FAQ

### What is the Hyper Retinol EX 1.0 Serum?

Hyper Retinol EX 1.0 Serum is Isntree's concentrated serum (20ml), formulated as treatment step in a Korean skincare routine. It suits sensitive, dry, normal skin types, and it is sourced here as the authentic Korean-market formula rather than a US-shelf reformulation.

### How should I use the Hyper Retinol EX 1.0 Serum?

Smooth two to three drops over cleansed and toned skin morning and evening, patting gently until absorbed before a moisturizer. Working it in this order keeps the concentrated texture behaving the way Isntree formulated it to, rather than rushing straight to the next step in the routine.

### How often should I use this serum?

Morning and evening, or evening only for a stronger treatment active, worked in gradually if skin is new to it. Consistency across a full skin cycle of several weeks matters far more than an occasional use for a serum like this one, since most of its benefit shows up with steady, repeated application.

### Who is this serum best suited for?

This serum is best suited for sensitive, dry, normal, combination skin, particularly anyone dealing with dullness and an uneven-looking tone. Patch test first if skin is very reactive, even though this ingredient is gentler than a true retinoid.

### What are the key ingredients in this serum?

The formula lists Niacinamide, Bakuchiol and Retinol among its ingredients, alongside the rest of the base that carries them across the skin. Each one is named here in the exact form it appears on Isntree's own ingredient list, not inferred from the product name.
