SOMEBYMI AHA BHA PHA 30 Days Miracle Serum 50ml

A bi-phase calming serum that balances oil and moisture

This is a bi-phase serum with a 7:3 ratio of moisturizing oil layer to calming water layer. Shake before use to blend the two phases, allowing moisture and oil to absorb harmoniously into skin. It helps balance combination skin that's dehydrated yet oily by delivering hydration where it's needed while controlling excess sebum. Formulated with 14.5% Centella Asiatica Extract and 10,000ppm Tea Tree Leaf Water to quickly soothe sensitized skin, plus AHA (exfoliating agent), BHA (pore-clearing agent that dissolves impurities), and PHA (gentle exfoliating agent) to gently refine excess oil and dead skin buildup.

Clinically proven calming and hydration after 2 weeks

In a human application test, 2 weeks of use showed an 8.5% improvement in skin calming and a 40.91% increase in skin hydration. Non-comedogenic tested (won't clog pores), dermatologist-tested, and passed a low-irritation test with a 0.00 irritation score. Free from 20 ingredients of concern including 7 types of parabens, phenoxyethanol, and triclosan, making it safe for even sensitive skin.

Calming care for combination, acne-prone, and sensitive skin

Recommended for combination skin that needs moisture without the heaviness, acne-prone skin struggling with frequent breakouts, and sensitive skin that reacts easily to irritation. For normal to dry skin, dispense about 1/3 of the dropper; for oily skin, use about 1/4. Warm the serum between your palms, then gently press into face and neck until fully absorbed.

This is a bi-phase serum — use it after toner

In a K-beauty routine, serum comes after toner and before moisturizer. This is a bi-phase formula with separate water and oil layers, so it's important to shake the bottle well before each use to blend them together. For best absorption, apply it after prepping your skin with a cleanser and toner from the same line.

Safe for morning and evening use

Even though it contains AHA (exfoliating), BHA (pore-clearing), and PHA (gentle resurfacing), the serum format keeps the concentration gentle enough for daily use. That said, if your skin feels sensitive, stick to evening application only, and always follow up with SPF in the morning.

Adjust the amount based on your skin type

Shake the bottle well to mix the water and oil layers. For normal to dry skin, use about 1/3 of a dropper; for oily skin, 1/4 is usually enough. Warm the serum between your palms, then gently press it into your face and neck until fully absorbed.

Routine pairings by skin concern

• Dehydrated oily skin: Use this serum on its own after a lightweight toner, or finish with a light hydrating cream
• Acne-prone skin: Pair it with the toner and cream from the same line for balanced oil and moisture control
• Extra dry days: Layer a rich moisturizer over the serum to lock in hydration and prevent moisture loss

Precautions when using acid-based products

Because this contains AHA, BHA, and PHA, layering it with retinol on the same day may cause irritation. If you're new to acids, start by using it every 2–3 days and monitor how your skin responds. The formula is non-comedogenic and dermatologist-tested for sensitivity, but if you experience redness or stinging, discontinue use and consult a dermatologist.
