Skin-Nomad's Take — At a Glance

• Smooths rough, bumpy arms and breakout-prone backs
• Three acids, AHA, BHA and PHA, with calming Centella
• A leave-on body exfoliant that stays comfortable to use

Rough, bumpy upper arms and a back that breaks out are texture problems, and a plain moisturiser has nothing to say to either. The SOME BY MI AHA BHA PHA Miracle Calming Body Lotion puts three acids to work at once, AHA on the surface, salicylic acid inside the pore and PHA doing a gentler version of both, with a Truecica Centella complex holding the irritation down. SOME BY MI built its reputation in South Korea on exactly this pairing of acids with Centella, and this is that formula scaled up for body skin.

Key Benefits

• AHA lifts the dead surface layer while salicylic acid works inside the pore: The two act at different depths, which is what rough upper arms and a congested back need at the same time. Salicylic acid is oil-soluble, so it moves into the sebum blocking the follicle rather than passing over the top of it.
• PHA is the larger molecule, and that is precisely the point: It penetrates more slowly than AHA, exfoliating with less sting, and draws water into the skin as it goes. On body skin that has only ever been washed and ignored, that combination refines texture without leaving it tight.
• Keeping the exfoliation comfortable is the job of the Truecica complex: Centella with tea tree brings down the visible redness that three acids across a large area would otherwise leave behind. It is the difference between a product used for a fortnight and one that stays in the routine.

Texture & Finish

It is a thin, fast lotion rather than a cream, and it disappears without the greasy film that would make a shirt cling. Glycerin and plant oils keep the finish soft, so freshly exfoliated skin feels supple rather than stripped.

Note: Three leave-on acids is a real dose for body skin, so skin new to acids does better easing into it than going daily from the start.

Ideal For

• Skin types: Normal, combination and oily body skin, skin prone to keratosis pilaris, and sensitive body skin introduced gradually.
• Skin concerns: Rough, bumpy upper arms, breakouts across the back, chest and shoulders, and dull or uneven tone.
• Best used by: People who have scrubbed their arms smooth for years and watched the bumps return within a week notice this most, because chemical exfoliation reaches into the follicle that a scrub only polishes over.

FAQ

Q: Should this go on damp skin or dry skin, and at what point in the day?
A: Dry skin, and in the evening. Water left on the surface dilutes the acids and spreads them unevenly across an area as large as a back, so towel off properly and give skin a couple of minutes first. Evening application also keeps a freshly exfoliated chest or pair of arms away from the strongest part of the day's sun.

Q: How is this different from a standard body lotion?
A: A standard body lotion adds water and oils to the surface and leaves the texture underneath as it found it. The SOME BY MI AHA BHA PHA Miracle Calming Body Lotion moisturises too, but its working parts are AHA, salicylic acid and PHA, which loosen and clear the dead cells and pore blockages that make skin feel bumpy in the first place. It treats rough body skin as an exfoliation problem rather than a dryness one.

Q: Will this get rid of keratosis pilaris for good?
A: No, and no topical product will. Keratosis pilaris is keratin building up around the hair follicle, and the tendency towards it is largely inherited, so the bumps come back when exfoliation stops. What a leave-on acid lotion does is keep that build-up cleared and the surrounding redness down for as long as it is in use, which in practice is what smooth upper arms look like.

Q: Do the acids make my skin more sensitive to the sun?
A: AHAs increase sun sensitivity, and body skin is no exception to that. Arms, chest and shoulders that will be uncovered want sunscreen during the day, which is worth planning for through summer in particular. The backs of the upper arms are the classic spot for this lotion and the first area a t-shirt stops covering in June.

The clever part is not the acids, which are everywhere, but the Centella sitting underneath them, because a body exfoliant only earns its place if you can stand to use it all year.
