Frequently asked questions

Yes. Men can use the Illuminating Intimate Serum on the groin crease, inner thighs and underarms, the areas where friction and shaving most often leave darker skin. Apply a thin layer to clean, dry skin once or twice a day.

Keep it on external skin only and off the genitals, and skip freshly shaved or broken skin. Patch test first, and see a doctor if darkening appears suddenly or comes with itching or pain.

Shaving can cause dark spots on the bikini line, not directly but through the razor burn, ingrown hairs and razor bumps it often leaves behind. On melanin-rich skin, each bout of inflammation can leave a flat dark mark that lasts for months.

To lower the risk, shave with a sharp razor in the direction of hair growth, use a shaving gel, don't stretch the skin, and moisturize afterward. Trimming instead of shaving close is gentler still.

To prevent razor bumps and ingrown hairs on the bikini line, stop hairs from curling back into the skin. Shave less often or trim with clippers, shave with the grain using a fresh blade, and never pluck or pick at bumps.

Two or three times a week, a gentle exfoliating lotion with low-strength lactic or salicylic acid helps free trapped hairs. Wear loose, breathable underwear. If bumps are painful, filled with pus or keep coming back, see a doctor.

To stop inner-thigh chafing, reduce the friction between your thighs. Wear anti-chafe or cycling shorts under dresses and skirts, choose moisture-wicking fabrics, and apply an anti-chafing balm or a thin layer of petroleum jelly before long walks or workouts.

Keep the area dry with a talc-free powder in hot weather, and change out of sweaty clothes quickly. Less friction means less inflammation and, over the following months, less new darkening.

Laser hair removal usually causes the least ongoing irritation on the bikini line once the course is finished, because it reduces regrowth and ingrown hairs. On dark skin it must be done with a suitable laser, such as a long-pulse Nd:YAG, by an experienced provider, or it can burn and leave marks.

Waxing causes fewer ingrown hairs than close shaving for some people, but it can inflame skin for a day or two. Trimming is the gentlest everyday option.

Vitamin C hand cream can help dark spots on the hands look less noticeable over time, especially sun spots from years of UV. Hands get a lot of sun and are washed often, so a cream with a stable vitamin C plus moisturizing ingredients works well as a leave-on step.

Apply it after washing, at least twice a day, and put sunscreen on the backs of your hands. Expect 8 to 12 weeks, and have any spot that changes checked by a doctor.

Dark knees and elbows are caused mainly by friction and pressure from leaning, kneeling and crossing your legs, which thickens the skin and builds up pigment, plus dryness and dead skin that look darker. They're more common on medium and deep skin tones and are usually harmless.

Moisturize daily with a cream containing urea or lactic acid, exfoliate gently once or twice a week, and reduce pressure. Thick, velvety darkening elsewhere, such as on the neck, is worth checking with a doctor.

Yes, vitamin C works on the body as well as the face, for dark spots on the arms, legs, chest, back and shoulders. Body skin is thicker, so lotions and creams with stable forms like tetrahexyldecyl ascorbate or sodium ascorbyl phosphate are practical for large areas.

Don't use a strong, low-pH face serum on intimate skin, which is thinner and easily irritated. Apply vitamin C daily after showering, and use sunscreen on exposed areas.
