Piel que no parece IA: poros, vello y textura real

5 prompts para generar un rostro hiperrealista y sus macros — con la regla que lo cambia todo: los defectos se piden por su nombre, no con adjetivos.

POROS1
¿Qué es esto y cómo lo uso?

Objetivo

Generar un rostro que nadie identifica como IA y cuatro macros de la misma persona. La clave no es pedir más calidad: es enumerar los defectos —poros, vello, brillo desigual, asimetría— uno por uno, porque lo que no nombras no aparece.

El error que arruina el 90% de los retratos con IA

Pedir "ultrarrealista, 4K, piel perfecta".

Te devuelve una cara lisa, sin poros, con brillo de plástico. Y eso es exactamente como se ve la IA. La perfección es lo que te delata.

La regla: el defecto se pide POR SU NOMBRE

Esto me costó dos tandas de generaciones. Mis primeros macros del cuello y del hombro llevaban esta línea:

tiny natural imperfections left visible

Un adjetivo. El modelo lo ignoró y devolvió piel de catálogo. Cambió cuando dejé de describir y empecé a enumerar:

clearly OPEN PORES, visibly dilated, uneven in size · two raised moles, one darker · sun spots of different sizes · a faint pressure mark left by the shirt seam · loose threads at the fabric edge

Misma foto, mismo modelo, resultado incomparable. Si no lo nombras, no aparece.

Los seis defectos que hacen el trabajo

Estos son los que de verdad mueven la aguja. Van en todos los prompts:

Cuándo usar

  • Poros abiertos — dilatados y de tamaño desigual, en nariz, mejillas y frente.
  • Vello facial translúcido (peach fuzz) — en la mandíbula, el labio superior y el hombro, con la luz atrapándolo pelo por pelo.
  • Brillo desigual — grasa en la frente, la nariz y los pómulos; mate en el resto.
  • Asimetría — pecas irregulares, cejas con pelos en distintas direcciones, pestañas de largo desigual.
  • Enrojecimiento natural — en las aletas de la nariz, el lagrimal y el lóbulo.
  • Una imperfección concreta — un grano cicatrizando, un lunar en relieve, la marca de una costura.

$ An extreme close-up beauty portrait of a young woman, shot for a high-end skincare campaign. Her face fills most of the frame, turned three-quarters toward the camera, chin slightly lowered, looking directly into the lens with a calm, unbothered expression, lips softly parted. HER — these features must repeat identically in every later image: a young Latin American woman, 24 years old. Warm honey-toned skin with a natural golden undertone. Long dark-blonde hair with lighter sun-bleached strands around the face, pulled back loosely so that fine baby hairs escape all along the hairline and temples. Large light hazel-green eyes with a darker limbal ring. Full, naturally thick eyebrows with individual hairs going in different directions, slightly unruly at the arch. A straight nose with a very small bump on the bridge. Full lips with a defined cupid's bow. A scattering of small freckles across the nose and the tops of the cheeks, irregular and asymmetric. One tiny dark mole just above the right corner of the mouth. BEAUTY: she is strikingly beautiful in an editorial, campaign-level way — sculpted high cheekbones, a clean defined jawline, an elegant neck, symmetrical features. The face of a beauty campaign. SKIN — THIS IS THE ENTIRE POINT, render it with obsessive detail: completely unretouched. Visible open pores across the nose, the inner cheeks and the forehead. Dense translucent PEACH FUZZ covering the cheeks, the jawline and the upper lip, each fine hair catching the light. Natural dewy sheen concentrated on the cheekbones, the nose bridge and the brow bone, with matte areas between. Fine vertical texture lines on the lips and a slightly drier upper lip. Faint natural redness around the nostrils and at the inner corners of the eyes. Delicate fine lines at the outer corner of the eye. A single tiny blemish healing near the jaw. Realistic subsurface scattering — light passing through the edge of the ear and the thin skin of the eyelid. Individual eyelashes, irregular in length, some crossing. Absolutely NO airbrushing, NO skin smoothing, NO beauty filter, NO plastic finish. MAKEUP: barely there — a touch of cream blush on the cheeks, clear gloss on the lips, brushed-up brows. Skin visible through everything. WARDROBE: bare shoulders, or the collar of a soft cream cotton t-shirt at the very bottom edge of the frame. THE SET: a seamless studio background in a warm neutral greige, softly graduated from light to slightly darker, completely plain. THE LIGHT: one large soft light source high and slightly front-left, close to her, giving a soft wraparound quality with a gentle shadow under the jaw and along one side of the nose. Neutral to slightly warm white balance. No harsh contrast, no coloured gels, no rim light, no lens flare. CAMERA: 100mm macro lens at f/5.6, so the whole face stays sharp — the pores, the peach fuzz and the individual lashes are all resolved. Shot on a medium-format camera. Very fine natural grain. No shallow depth of field blur across the face, no bokeh, no colour grading. Photorealistic, indistinguishable from a real beauty campaign photograph. ABSOLUTELY NO TEXT anywhere in the image: no lettering, no logos, no watermarks, no graphics.

$ FRAMING: an EXTREME macro of the lower half of her face only — from just under the nose down to the chin, filling the entire frame. Her lips are softly parted, showing the edge of her upper teeth. Slightly angled, not straight on. WHAT MUST BE RESOLVED: the fine vertical texture lines running across both lips, the slightly drier and flakier upper lip, the wet gloss highlights sitting on the lower lip, the sharp ridge of the cupid's bow, the peach fuzz above the upper lip and along the chin, the open pores on the chin, and the tiny dark mole above the right corner of the mouth.

El ojo

Pestañas de largo desigual que se cruzan, las fibras del iris, las venitas del lagrimal y las cejas despeinadas. El más contundente de los cuatro.

$ FRAMING: an EXTREME macro of one eye only — the eyebrow above it, the eye itself and the top of the cheekbone, filling the entire frame. She is looking slightly off to the side. WHAT MUST BE RESOLVED: individual eyelashes of irregular length, some crossing over each other; the radial fibre structure of the hazel-green iris with its darker limbal ring; the fine red vessels in the white of the eye near the tear duct; the natural moisture on the waterline; individual eyebrow hairs growing in different directions, unruly at the arch; the freckles across the top of the cheekbone; the open pores below the eye; and the faint fine lines at the outer corner.

La oreja y el cuello

Poros dilatados junto a la oreja, pelitos sueltos del nacimiento, la luz atravesando el lóbulo y lunares repartidos sin orden.

$ FRAMING: an EXTREME macro of the side of her face — her ear, the hairline in front of it, the jaw and the side of the neck down to the collarbone, filling the frame. Her head is turned and slightly tilted so the neck creases naturally. THE IMPERFECTIONS THAT MUST BE VISIBLE — this is what the image is for, do not clean any of it up: - Dense translucent peach fuzz running down the jaw and the whole side of the neck, each hair lit from the side so the skin looks softly furred. - Fine baby hairs escaping along the hairline, curling in front of the ear and sticking to the skin. - Two or three soft horizontal creases where the neck bends, with the skin gathering naturally. - Clearly OPEN PORES on the cheek near the ear and along the jaw — visibly dilated, not smoothed. - A scattering of irregular freckles and two small raised moles on the neck, one of them slightly darker. - Faint natural redness on the earlobe and where the ear meets the jaw, with the skin thin enough that light passes through the lobe. - The small natural bumps and folds of the ear cartilage, and a tiny vertical crease in the tragus. - One fine vein faintly visible under the skin of the neck.

$ FRAMING: an EXTREME macro of her bare shoulder and collarbone with the very edge of her jaw at the top of the frame, filling the whole image. The soft cream cotton t-shirt has slipped off the shoulder and its fabric sits at one edge. THE IMPERFECTIONS THAT MUST BE VISIBLE — this is what the image is for, do not clean any of it up: - Fine downy hair covering the shoulder and the upper back, catching the light so the skin edge looks softly furred against the background. - Clearly OPEN PORES across the shoulder and the top of the chest — visibly dilated, uneven in size. - A dense scattering of irregular freckles and sun spots of different sizes, plus one raised mole and one small flat beauty mark. - Slightly uneven skin tone: a faint patch of natural redness over the collarbone, and marginally paler skin where the t-shirt has been sitting. - Two or three fine soft creases in the hollow of the collarbone where the skin folds. - A faint pressure mark left on the shoulder by the shirt seam. - The individual cotton fibres and the visible weave of the t-shirt where it touches the skin, with a few loose threads at the edge.

Cómo lo adaptas

Cómo usar

  1. Cambia la persona en el primer prompt: edad, tono de piel, color de ojos, pelo. Y cámbiale las marcas de identidad — las pecas, el lunar, la cicatriz.
  2. Genera el rostro y apruébalo antes de seguir. Si esa foto no convence, los cuatro macros no la salvan.
  3. Elige tus cuatro encuadres. Los míos son labios, ojo, oreja-cuello y hombro, pero funcionan igual las manos, la nuca o el empeine: donde haya piel, hay argumento.
  4. Enumera los defectos de esa zona concreta. No repitas los míos: el hombro pide manchas de sol, las manos piden padrastros y venas, la nuca pide pelitos sueltos.

Errores que te van a pasar

  • Sale con piel de cera. No enumeraste. Vuelve a la lista de los seis defectos y nómbralos uno por uno.
  • Cambia de persona entre macros. El bloque de identidad quedó corto, o no le pasaste la primera foto como base.
  • Sale demasiado bonito. Si parece anuncio de crema, no sirve. Sube el desorden: un grano, una ceja despeinada, una marca de ropa.
  • El fondo cambia entre tomas. El modelo conserva a la persona pero se reinventa el escenario. Descríbelo igual en cada prompt.
