Kaine Rosemary AHA Night Serum

An overnight serum that targets texture and pores while you sleep

A night serum formulated with 9% lactic acid, 0.5% succinic acid, and 7% rosemary leaf extract. Lactic acid gently resurfaces the skin by dissolving built-up dead cells, while succinic acid works deeper to help clear blackheads from within the pores. Rosemary leaf extract soothes and hydrates, so skin stays comfortable even after exfoliation. The bouncy, high-concentration watery texture absorbs seamlessly into skin for a second-skin finish.

Clinical results after 2 weeks: visible pore improvement

In a 2-week clinical study with 21 adult participants, all four pore metrics showed improvement.

• Pore area reduced by 21.15%
• Pore density reduced by 17.03%
• Pore depth reduced by 19.25%
• Pore count reduced by 17.21%

Dermatologist-tested on sensitive skin with a non-irritating result, making it suitable even for reactive complexions.

If uneven texture is keeping your makeup from sitting smoothly

Enriched with panthenol, betaine, and allantoin to soothe and hydrate, this serum helps protect the skin barrier even as it exfoliates. Free from synthetic fragrance, synthetic colorants, parabens, phenoxyethanol, animal-derived ingredients, and mineral oil. Certified vegan by EVE VEGAN in France. For first-time use, start with once a week and gradually increase to 2–3 times per week depending on how your skin responds.

Evening Skincare Exfoliation Step

This is a night serum designed to be used after cleansing and toning, during your essence or serum step. Because it contains AHA (an exfoliating ingredient), it's formulated for evening use only. Follow with a moisturizing cream to support overnight skin renewal.

Evening Only, Build Up Gradually

With 9% lactic acid, this product must be used in the evening only. Start with once a week, then gradually increase to 2–3 times per week as your skin adjusts. Be sure to cleanse thoroughly with a cleanser the following morning.

Shake Well Before Applying Along Skin Texture

Shake the bottle well before use to mix the formula. After cleansing, pat skin dry and dispense an appropriate amount. Smooth evenly over the face, following the direction of your skin texture. The bouncy, watery serum texture absorbs seamlessly into skin.

Routine Combinations by Skin Concern

• For pores and texture: Follow this serum with a lightweight hydrating cream, and apply sunscreen thoroughly the next morning.
• For dryness concerns: Prep skin with a hydrating toner before the serum, then layer on a generous amount of moisturizing cream.
• For post-breakout marks: Use this serum 2–3 times a week, and on alternate days, give your skin a rest with a calming ampoule.

Precautions When Using AHA

AHA can increase sun sensitivity, so sunscreen is essential the following morning. Avoid using retinol or other exfoliating products on the same day to prevent irritation. While this product has been tested on sensitive skin and received a non-irritating rating, discontinue use and consult a dermatologist if you experience redness or stinging.
