Brightening Vitamin C & Saffron Serum

Sunlight Serum is formulated for all skin types, tones, and genders, including sensitive and melanin-rich skin. It's particularly loved by women whose skin has been changing with age or life stage, including perimenopause and menopause. Saffron has been used in Indian skin traditions for centuries on deeper skin tones, and the oil-soluble Vitamin C in our formula is gentler than the water-soluble version found in most serums. Please note the formula contains Sweet Almond Oil (not suitable for those with nut allergies) and essential oils, so although used in very safe concentrations, we err on the side of caution and don't recommended during pregnancy or breastfeeding; our Moonlight Serum is pregnancy-safe instead.

Most customers notice their skin looks more radiant, feels more hydrated, and shows improvement in tone within 8 to 16 weeks of daily use. For stubborn pigmentation and dark spots, allow up to 24 weeks. If you're a few weeks in and not sure whether it's working, that's completely normal. Some customers also experience a brief dry phase in the first week or two as their skin adjusts; applying to slightly damp skin usually resolves it.

Most Vitamin C serums use L-Ascorbic Acid, which is water-soluble, oxidises quickly, and can feel harsh on reactive skin. Sunlight Serum uses Ascorbyl Tetraisopalmitate, an oil-soluble form of Vitamin C that stays stable in the bottle and feels gentler on skin. The formula is also 0% water and 100% active ingredients, so every drop is doing something. It's designed to sit well under SPF and makeup without feeling greasy.

Yes, always wear SPF as the final step in your morning routine. Unlike some Vitamin C formulas, Sunlight Serum is not photosensitive, so daylight won't make your skin more reactive. Apply 2-3 drops to slightly damp skin, let it settle for a minute or two, then apply your SPF on top. You can always add more drops if your skin is on the drier side (listen to your skin). Many customers also add a drop into their foundation for a softer, more radiant finish.

Sunlight Serum has a distinctive warm, Ayurvedic scent that comes from the natural essential oils in the formula: calming Lavender, grounding Clary Sage, softly floral Ylang-Ylang, and a bright note of Orange Peel. There are no added synthetic fragrances, just the natural aromas of these botanicals coming together. For many customers, this is part of what makes the morning ritual feel intentional, like a few quiet seconds of spa before the day begins. The scent is most noticeable at first application and settles within a couple of minutes as the serum absorbs.

Despite being an oil-based formula, Sunlight Serum is designed to absorb fully into the skin rather than sit on top. The key is applying it to slightly damp skin and pressing it in gently rather than rubbing. Most customers find it sits beautifully under both SPF and makeup, and many use it as a natural primer. Some even mix a drop into their foundation for a softer, more radiant finish. If your skin feels oily, try using less; a little really does go a long way.

Yes, Sunlight Serum layers well with most skincare routines. If you use stronger actives like prescription retinoids or exfoliating acids, we recommend keeping those for the evening and using Sunlight Serum in the morning. Many of our customers pair it with our own Moonlight Serum at night, which uses Bakuchiol as a gentler alternative to retinol. If you're on prescription medication or treatment for a skin condition, it's always worth checking with your GP or dermatologist first.

We offer a 30-day money-back guarantee on individual products, even if opened. If Sunlight Serum isn't right for you, we'll make it right. Every skin is different, and we'd rather you find what works than keep something that doesn't. You can read our full returns information here.
