Bifida Biome Complex Ampoule

Yes, this ampoule is generally considered safe for use during pregnancy and breastfeeding. It does not contain retinoids, salicylic acid, hydroquinone, or chemical sunscreens - the main ingredients typically advised to avoid during pregnancy. The formula features pregnancy-safe ingredients like niacinamide, hyaluronic acid, peptides, and probiotics. However, as with any skincare product during pregnancy, it's recommended to consult with your healthcare provider before use.

This product should be used with caution if you have fungal acne. While Bifida Ferment Lysate itself is considered safe for fungal acne (as it's not lipid-based and doesn't feed Malassezia), the formula contains Saccharomyces Ferment Filtrate, which is a yeast-derived ferment that may potentially aggravate fungal acne in some individuals. If you're prone to fungal acne, consider patch testing first or opt for a simpler Bifida-only formula like One Thing Bifida Ferment Lysate.

Yes, this ampoule is compatible with most active ingredients. For retinol: Apply the ampoule first, let it absorb, then apply retinol. For Vitamin C (L-Ascorbic Acid): Use Vitamin C in AM and ampoule in PM, or apply Vitamin C first and ampoule after. For AHA/BHA: Use acids first on clean skin, wait 20-30 minutes, then apply the ampoule. The ampoule's barrier-supporting properties can actually help counteract potential irritation from actives.

This ampoule is suitable for all skin types, but it's particularly excellent for dry, dehydrated, sensitive, combination, and mature skin. Oily skin types also benefit from its lightweight, non-greasy texture and niacinamide content that helps regulate sebum. Those with compromised skin barriers, dullness, or early signs of aging will see the most dramatic results. The only skin type that should exercise caution is those prone to fungal acne.

Most users notice immediate hydration and skin plumpness after the first application. More significant results typically appear within 2-3 weeks of consistent use, including improved skin texture, enhanced radiance, and a "blurred" appearance to pores. Clinical studies showed 95.2% user satisfaction after 3 weeks. For anti-aging benefits like reduced fine lines and improved firmness, expect to see results after 6-8 weeks of regular use.

Apply this ampoule after cleansing and toning, as the third step in your routine. The general order is: Cleanser → Toner → THIS AMPOULE → Essence/Serum (if using additional) → Moisturizer → Sunscreen (AM only). Apply to slightly damp skin for optimal absorption. The ampoule can be used both morning and evening.

No, this ampoule has a low comedogenic rating of 1/5. The lightweight, watery-serum texture absorbs quickly without leaving a heavy or greasy residue. It does not contain common pore-clogging ingredients like heavy oils or comedogenic waxes. The formula includes niacinamide which actually helps minimize pore appearance. It's suitable for acne-prone skin, though those with fungal acne should exercise caution due to certain fermented ingredients.

The Period After Opening (PAO) is 12 months. Once opened, use within one year for optimal efficacy. The dark glass bottle helps protect the active ingredients from light degradation. Store in a cool, dry place away from direct sunlight. If the product changes color, develops an unusual smell, or separates significantly, discontinue use. With regular twice-daily application of 3-5 drops, a 50ml bottle typically lasts 2-3 months.
