    Why it works

    Undotted Serum is a targeted leave-on serum for skin that looks uneven, blemish-prone, dull or prone to post-blemish marks.

    Tone and blemish-prone support

    Azelaic acid and acetyl glucosamine support a more even-looking and balanced skin appearance. Skin looks clearer and more refined over time.

    Pore-care botanical support

    Willow bark extract supports the serum’s blemish-prone and pore-care profile. Skin feels fresher and more balanced.

    Hydration and comfort support

    Glycerin, betaine, saccharide isomerate, glyceryl glucoside and propanediol support water-binding hydration. Skin feels softer and more comfortable.

    Key Ingredients

    Azelaic Acid

    A targeted ingredient used for uneven-looking tone and blemish-prone skin support. In this formula, it helps skin look clearer, more balanced and more even over time.

    Willow Bark Extract

    Also listed as Salix Alba (Willow) Bark Extract, this botanical extract supports the serum’s pore-care profile. It helps skin feel fresher, more balanced and more refined.

    Acetyl Glucosamine

    A skin-conditioning ingredient used for tone and texture support. It helps support a smoother, more even-looking and cared-for skin appearance.

    Betaine

    A comfort-supporting humectant that helps balance the targeted serum format. It helps skin feel softer, more comfortable and less dry.

    How to use

    Apply after cleansing or toner as the serum step, morning and/or evening. Use before moisturiser, and before sunscreen in the morning.

    Introduce gradually, especially if skin feels sensitive, dry or reactive.

    FAQ

    What does Undotted Serum do?

    Undotted Serum is a targeted serum for skin that looks uneven, blemish-prone, dull or marked after breakouts. It uses azelaic acid to support a clearer-looking and more balanced skin appearance, while acetyl glucosamine helps support a smoother, more even-looking tone over time. Willow bark extract adds gentle pore-care support, and humectants such as glycerin, betaine and saccharide isomerate help keep the formula comfortable on the skin. This makes it useful for post-blemish marks, uneven-looking tone and skin that needs targeted support without feeling overly drying.

    Who is Undotted Serum best for?

    It is best for normal, combination and oily skin that looks uneven, blemish-prone, dull or prone to post-blemish marks. Sensitive-feeling skin can introduce it gradually and use moisturiser to support comfort.

    How does Undotted Serum help with post-blemish marks?

    Post-blemish marks can appear after a breakout when the skin looks uneven, dull or discoloured in the area where the blemish was. Undotted Serum supports this concern with azelaic acid and acetyl glucosamine, which help the skin look more even and balanced over time. Willow bark extract adds gentle pore-care support, while glycerin, betaine and saccharide isomerate help keep the serum comfortable so the skin does not feel overly dry or stripped during use. For best results, use consistently and wear sunscreen in the morning, since UV exposure can make post-blemish marks look more noticeable.

    Is Undotted Serum exfoliating?

    It should not be treated as an exfoliating serum or peel. Willow bark extract is included, but it should not be positioned as a BHA treatment. Use it as a targeted serum for clearer-looking, more balanced and more even-looking skin.

    Can I use Undotted Serum every day?

    Yes, if your skin tolerates it well. Start gradually, especially if your skin feels sensitive, dry or reactive, then increase use as needed. Use sunscreen in the morning.

    Can I use Undotted Serum with retinoids, AHA or BHA?

    Be careful when combining Undotted Serum with strong exfoliating acids, retinoids or other targeted actives. To avoid doing too much in one routine, start by using them separately: for example, Undotted Serum in the morning and retinoids at night, or Undotted Serum on nights when you are not using AHA, BHA or retinoids. If skin feels dry, tight, stinging or uncomfortable, reduce frequency and focus on moisturiser and sunscreen.

    Can I use Undotted Serum while pregnant or breastfeeding?

    Pregnancy and breastfeeding safety are not clearly supported for this product. If you are pregnant, breastfeeding or unsure, check with your healthcare provider before use.
