FAQ
  • Q. What are the common skin responses when adjusting to retinol? A. Retinol typically requires an initial adjustment period of up to 2 weeks. During this time, you may experience temporary reactions such as mild tingling, redness, or flaking. However, some people may not experience any noticeable reactions at all—this can vary depending on individual skin sensitivity. For external use only; patch test recommended prior to full use. Discontinue if irritation occurs.
  • Q. I didn’t feel any reaction after the first use. Can I apply it to my entire face now? A. In some cases, retinol reactions may appear later rather than immediately. Even if you don’t feel any discomfort at first, we recommend that you do not increase the amount or frequency of use right away. Please follow the usage guide carefully during the first two weeks.
  • Q. What should I do if my skin feels irritated? A. If you experience irritation while using the product, try reducing the frequency of use. You can also mix the serum with a soothing serum or a moisturizer to minimize discomfort.
  • Q. Is it gentle enough for long-term use? A. Yes, as long as you’ve gone through the initial adjustment phase according to the instructions and your skin is responding well without discomfort, it is suitable for long-term use.
  • Q. Should I only use this at night? A. Yes, we recommend using retinol products in your nighttime skincare routine because retinol is sensitive to light and heat. Even if you don't apply it during the day, retinol can remain active in your skin. So it's important to wear sunscreen daily during the period you’re using this product.
How to use

What makes it work

Four things worth knowing before you add it to your routine.

Concentrated where it counts

Actives

Concentrated where it counts

The active sits at a percentage high enough to do something and low enough to stay tolerable on daily use. No filler percentages for the label.

Absorbs in seconds

Texture

Absorbs in seconds

A lightweight layer that sinks in without pilling under sunscreen or makeup, so nothing in your routine has to move.

Built for mature and sensitive skin

Skin types

Built for mature and sensitive skin

Fragrance free and non-comedogenic. Suitable for dry, combination and reactive skin. Patch test first if your skin is very reactive.

Results

What to expect, honestly

Texture and hydration shift within the first two weeks. Tone and spots take longer, usually eight to twelve weeks of consistent use.

How to use it

Four steps. Same every day.

1 4

  1. Start on clean skin

    Step 1

    Start on clean skin

    Cleanse and pat dry. Leaving skin slightly damp helps the next layer spread further.

  2. Warm it between your fingers

    Step 2

    Warm it between your fingers

    Two or three drops is enough for the whole face. Warming it first makes it absorb faster.

  3. Press, do not rub

    Step 3

    Press, do not rub

    Press into the skin in upward motions. Rubbing drags at the skin and wastes product.

  4. Seal and protect

    Step 4

    Seal and protect

    Follow with moisturiser. In the morning, finish with a broad-spectrum SPF, every day without exception.

What professionals say

  • The formulations are honest. The percentages match what the label claims, and the textures are pleasant enough that people actually finish the bottle, which is most of the battle.
