Skin Type Compatibility
How well this product works for different skin types
Contains hydrating ingredients like glycerin, squalane, and sodium hyaluronate, which support moisture retention. However, as a serum, it may need to be layered with a richer moisturizer for optimal hydration in very dry skin.
Lightweight, non-comedogenic ingredients like squalane and absence of heavy oils make it suitable for oily skin. The serum texture absorbs well, but some with very oily skin may prefer more mattifying products.
Formulation is fragrance-free and contains soothing licorice extract, but vitamin C derivatives and botanical extracts can occasionally cause irritation in sensitive skin. Patch testing is recommended.
Balanced hydration from squalane and hyaluronic acid suits both dry and oily zones. Lightweight serum texture is appropriate for combination skin.
Non-comedogenic squalane and anti-inflammatory licorice extract are beneficial, but vitamin C derivatives can sometimes trigger breakouts or irritation in acne-prone individuals. Monitor for reactions.
Well-balanced, gentle formulation with hydrating and brightening ingredients is ideal for normal skin, with minimal risk of irritation or pore-clogging.
Seasonal Usage Recommendations
How to use this product throughout the year
Winter
Use the serum daily to help combat dryness and dullness from cold air and indoor heating. Layer with a richer moisturizer to lock in hydration, as squalane and hyaluronic acid support moisture retention.
Spring
Continue daily use to address post-winter uneven tone and dark spots. The lightweight formula suits changing humidity. Pair with sunscreen, as vitamin C can increase sun sensitivity and spring UV levels rise.
Summer
Apply in the morning under sunscreen to help prevent and treat sun-induced pigmentation. The serum’s lightweight, non-greasy texture is suitable for humid weather. Ensure diligent sun protection to maximize brightening effects.
Fall
Maintain use to repair summer sun damage and prepare skin for drier months. As temperatures drop, consider layering with a hydrating moisturizer to support the skin barrier and prevent moisture loss.
Enhanced Usage Instructions
Detailed usage guidance for different skin concerns and best practices
Usage by Skin Concern
Dry Skin
After cleansing, apply 1-2 pumps of the serum to slightly damp skin to maximize hydration. Follow with a rich moisturizer and facial oil if needed. The squalane and hyaluronic acid will help maintain moisture. Use morning and night for best results.
Oily Skin
Use 1 pump of serum on clean, dry skin, focusing on areas with dark spots or uneven tone. Allow the serum to absorb fully before applying a lightweight, oil-free moisturizer. Use once daily at first, increasing to twice daily if tolerated.
Sensitive Skin
Patch test before first use. Start with a small amount (half a pump) every other night, gradually increasing to nightly use as tolerated. Avoid applying to broken or irritated skin. Always follow with a gentle, fragrance-free moisturizer.
Combination Skin
Apply 1 pump to cleansed skin, concentrating on areas with hyperpigmentation or uneven tone. Use a lightweight moisturizer on oilier areas and a richer one on dry patches. Can be used morning and night if no irritation occurs.
Acne-Prone Skin
The serum is non-comedogenic, but start with once daily use to monitor for breakouts. Apply a thin layer to affected areas after cleansing. Follow with an oil-free, non-comedogenic moisturizer. Avoid layering with strong exfoliants or retinoids initially.
Usage Tips & Best Practices
Daily Use
For most skin types, apply morning and evening after cleansing and before moisturizer. Always follow with sunscreen in the morning.
Night Use
Use after cleansing and before moisturizer. Nighttime use is especially beneficial for skin repair and to avoid potential vitamin C degradation from sunlight.
Frequency
Start with once daily use, increasing to twice daily (morning and night) as tolerated. Sensitive skin may benefit from alternate day use initially.
Amount
Use 1-2 pumps (approximately a pea-sized amount) per application. Adjust based on coverage needs and skin tolerance.
Best Time
Best applied in the morning for antioxidant protection and at night for skin repair. Always follow with sunscreen during the day.
