Honest answersto real questions.

Radiance Powder is a vitamin-based supplement designed to support skin from within. It contains Vitamin C for collagen formation, B2 and B3 for normal skin maintenance, B6 for hormonal regulation, plus prebiotics, 13 probiotic strains, and natural fibres to support gut wellness — which plays a crucial role in skin health.

Mix one scoop (approx. 10 g) with 250 ml of water, juice, or a smoothie. Stir well and drink immediately. Once daily, ideally in the morning or before meals.

Most customers report visible improvements within 4–8 weeks of consistent use. For optimal results, we recommend taking Radiance Powder daily for at least 90 days. Results vary depending on lifestyle, diet, and individual skin condition.

Yes. Radiance Powder works systemically through your gut and bloodstream. Whether your skin is oily, dry, combination, or sensitive, the vitamins and probiotics support healthy skin function from within.

Yes. Radiance Powder is 100% vegan and free from common allergens including gluten, dairy, and soy. All ingredients are plant-based and selected for purity and effectiveness.

If you are pregnant, breastfeeding, or planning to become pregnant, please consult your healthcare provider before taking any supplement.

Generally yes. If you take prescription medications or have any medical conditions, please consult your healthcare provider before adding any new supplement to your routine.

GlowScreen SPF50 is a lightweight, oil-based sunscreen with broad-spectrum UVA/UVB protection and a natural, luminous glow. No white cast. Absorbs quickly. Enriched with antioxidants (Magnolia bark, Vitamin E, Grape seed oil) that nourish your skin while protecting it.

2–3 pumps onto face and neck as the last step of your skincare routine. Wait 5–10 minutes for absorption before applying makeup. Reapply every 2 hours when in direct sun, or after swimming, sweating, or towel-drying.

Yes — beautifully. Let the oil absorb fully (5–10 min), then apply foundation. The natural glow finish actually enhances most makeup looks.

Yes. Despite being oil-based, GlowScreen is non-comedogenic — the Squalane and Ceramide NP support the barrier without clogging pores. Many of our acne-prone customers find it the only SPF that doesn't trigger breakouts.

A combination of Tinosorb S, Avobenzone, Uvinul T 150, and Uvinul A Plus — modern broad-spectrum filters that are stable, effective, and don't damage marine ecosystems. The formula contains 16 ingredients total.

The 30 ml is the full-size bottle, lasting roughly 1–2 months for daily face use. The 5 ml sample is perfect for travel, testing the product, or carrying for reapplication.

MasterCell is our cleanest serum — only 17 ingredients, with Niacinamide (Vitamin B3) as the second ingredient (= very high concentration). It strengthens the skin barrier, regulates sebum, reduces pores and pigmentation, and smooths fine lines. Synergistic with Acetyl Glucosamine which stimulates the skin's own hyaluronic acid synthesis.

Apply 2–3 drops to clean, dry skin in the morning, before sunscreen and makeup. Can also be used at night. Suitable for daily use.

Yes — they are designed to complement each other. MasterCell in the morning (barrier support, niacinamide), RetinGold at night (cell renewal, retinol). Always finish with GlowScreen SPF50 in the morning when using RetinGold.

Yes. MasterCell contains Liquorice root extract (Dipotassium Glycyrrhizate) — one of the strongest natural anti-inflammatories — plus Aloe and Panthenol. The formula is specifically formulated to calm reactive, rosacea-prone, and sensitive skin.

MasterCell does not contain retinol, retinoids, or salicylic acid. Generally considered safe during pregnancy and breastfeeding, but we always recommend checking with your gynaecologist first.

RetinGold is our night serum combining gold-bound Retinol with a multi-active acne and brightening complex. The gold protects retinol from oxidation on its journey through the epidermis, enabling deeper, more stable delivery. 36 ingredients total, targeting all four causes of acne: inflammation, sebum, hyperkeratosis, bacteria.

Evening only. 2–3 drops onto clean, dry face and neck. Pat gently. Always apply SPF in the morning — your skin becomes more photosensitive when using retinol.

RetinGold contains 5% Azelaic Acid, Salicin (Willow bark), Usnic acid (Lichen extract), Zinc PCA, and Cucumber extract — addressing comedone formation, antibacterial action, sebum regulation, and pore cleansing in parallel.

Many customers see initial improvements (smoother texture, fewer new breakouts) within 4 weeks. Brightening and reduction of post-acne marks typically takes 8–12 weeks. Use consistently.

No. RetinGold contains retinol, which is not recommended during pregnancy or breastfeeding. Switch to MasterCell during this time — it's retinol-free and pregnancy-safe.
