Some By Mi organises its skincare into lines built around one main concern. The AHA BHA PHA 30 Days Miracle line is for oily, breakout-prone and congested skin; Yuja Niacin and Galactomyces Vitamin C are for dullness and uneven tone; Retinol Intense is for fine lines and texture; Beta Panthenol is for dry, irritated skin; and Truecica covers calming and sun protection. Pick the line that matches your main concern, then add from others as needed.
AHA BHA PHA 30 Days Miracle: for oily and breakout-prone skin
This is the line most people know Some By Mi for. It combines three types of exfoliating acids with tea tree, and it's aimed at clogged pores, excess oil and rough texture.
- What the acids do: AHA works on the surface for brighter-looking skin, BHA works inside the pore to help clear impurities, and PHA exfoliates gently while helping hold moisture. If you want a deeper explanation, read AHA vs BHA vs PHA.
AHA BHA PHA 30 Days Miracle Toner is the starting point. It contains 10,000ppm tea tree, AHA, BHA and PHA, and niacinamide, with a pH of 5.5, and is suitable for all skin types.
AHA BHA PHA 30 Days Miracle Serum adds 14.5% centella asiatica extract and 10,000ppm tea tree leaf water to the three acids. It's a step up if you want a leave-on treatment for congestion.
AHA BHA PHA 30 Days Miracle Acne Clear Foam is the cleanser in the line, with 5,000ppm salicylic acid, AHA, BHA and PHA, plus Truecica for soothing and calamine for oil care.
Who it suits: oily, combination and breakout-prone skin. Tip: you don't need every product. Using the toner, serum and cleanser together means a lot of acid, so start with one, use it a few times a week, and build up slowly.
Yuja Niacin: for dullness and uneven tone
The Yuja line is built around yuja (a citrus fruit) and niacinamide. Yuja Niacin Anti Blemish Serum is designed to help brighten skin tone, improve the look of dark spots and freckles, and give a boost of hydration.
Who it suits: anyone focused on a brighter, more even-looking complexion, including people with post-breakout marks. It pairs well with the Miracle line if you have both breakouts and marks.
Galactomyces Pure Vitamin C: for glow
Galactomyces Pure Vitamin C Glow Serum combines 75% galactomyces ferment filtrate with 3% ascorbic acid, plus niacinamide and adenosine. It's aimed at dull, uneven-looking skin and dark spots. It's a good morning serum under sunscreen if you want a vitamin C step.
Retinol Intense: for fine lines and texture
Retinol Intense Reactivating Serum contains retinol, retinal and bakuchiol, and uses Some By Mi's elastic-liposome technology. It's designed to help with the look of fine lines, uneven texture and dark spots, with a non-sticky, moisturising finish. The line also includes a Retinol Intense eye cream.
Who it suits: anyone starting to focus on ageing concerns. Use it at night, start a few times a week, and always wear sunscreen the next morning. Avoid using it on the same night as the Miracle acids when you're starting out.
Beta Panthenol: for dry, irritated skin
Beta Panthenol Repair Cream is the line to reach for when your skin feels tight, dry or sensitised. It contains panthenol, centella asiatica extract, niacinamide, allantoin and beta-glucan to hydrate, soothe and support the skin barrier.
Who it suits: dry and sensitive skin, and anyone using acids or retinol who needs a comforting moisturiser.
Truecica: for calming and sun protection
Truecica is Some By Mi's soothing ingredient complex, and it appears across several products. For daytime, Truecica Mineral Calming Tone Up Suncream SPF 50+ PA++++ combines Truecica and aloe vera with a natural tone-up effect, and is made with sensitive and irritated skin in mind.

FAQ
Is the Some By Mi Miracle line good for sensitive skin?
It contains three acids, so introduce it slowly. Start with the toner two or three times a week and pair it with a soothing moisturiser such as Beta Panthenol Repair Cream. Stop if you get ongoing stinging or redness.
Can I use the Miracle Toner and Retinol Intense together?
It's best to use them on alternate nights, especially at first, to reduce the risk of irritation.
Which Some By Mi product is best for dark spots?
The Yuja Niacin Anti Blemish Serum and the Galactomyces Pure Vitamin C Glow Serum are both aimed at uneven tone and dark spots. Daily sunscreen is essential alongside either.
How long until I see results?
Give any new routine at least four to eight weeks of consistent use.
