The Ethylated Ascorbic Acid 15% Solution is an antioxidant formula that aims to even skin tone. The Squalane Cleanser is a moisturizing makeup-removing cleanser that is gentle enough for everyday use. The Caffeine Solution 5% + EGCG targets dark circles and puffiness around the eye contour.

2. Niacinamide 10% + Zinc 1%: This water-based serum contains a high 10% concentration of Niacinamide (vitamin b3) and zinc PCA. It boosts skin brightness, improves skin smoothness, and reinforces the skin barrier over time. It is suitable for all skin types and is vegan, gluten-free, and cruelty-free.

3. Soothing & Barrier Support Serum: This serum contains ingredients that help to improve several skin conditions, including acne, rosacea, and atopic dermatitis. It contains SymCalmin, which reduces itchiness and redness, and ceramides, which strengthen the skin barrier and improve skin hydration.

4. Ascorbyl Glucoside Solution 12%: This serum contains a form of vitamin C that has antioxidant protection, collagen-boosting, and hyperpigmentation-fading properties. It is useful to help active ingredients for self-tanning, anti-acne, or skin-whitening to penetrate deeper and work better.

5. Ethylated Ascorbic Acid 15% Solution: This serum is an antioxidant formula that aims to even skin tone. It contains a form of vitamin C that is stable and effective. It is suitable for all skin types and is vegan, gluten-free, and cruelty-free.

Positive aspects of these serums include their effectiveness in brightening the skin, improving skin texture, and evening out skin tone. They are also suitable for all skin types and are vegan, gluten-free, and cruelty-free. Negative aspects may include skin irritation or sensitivity to some of the ingredients.
