The 48-Hour Protection Formula

"Started using this on the back of my head and neck after haircuts and I finally stopped getting ingrown hairs"
-
"This actually faded the marks on my underarms, my skin looks even and healthy now.”
-
"I noticed less redness the very next day. Super gentle but so effective."
Bumps Fade. Marks Clear.
With consistent use (2-4 weeks), dark marks from old ingrowns start to fade.
How It Works
Inflamed skin traps hairs and triggers hyperpigmentation. We break the cycle by calming inflammation before exfoliating.
-
Soothe
Licorice root extract calms inflammation immediately after shaving — stopping the "angry skin" response that traps hairs.
No sting. No burn.
-
Exfoliate
Triple-acid blend (BHA + AHA + PHA) dissolves dead skin cells during the 24-72 hour regrowth window — preventing follicles from blocking hairs.
PHA is the gentlest exfoliant, safe for sensitive areas.
-
Brighten
Niacinamide + licorice root inhibit melanin production. PHA resurfaces skin to bring fresh, even-toned cells to the surface.
Marks fade in 2-4 weeks with consistent use.

Finally no more bikini bumps
I used to get clusters of razor bumps and redness along my bikini line every time I shaved. It was embarrassing and painful. After using this serum daily, the difference is unbelievable, my skin looks smooth, clear, and way less irritated. I finally feel comfortable wearing swimsuits without worrying about bumps showing.

Finally something that works for my neck
I’ve had ingrown hairs on my neck and jawline for years. Almost everything I tried either burned or made it worse. I started using this right after shaving and noticed a difference within the first week. My skin felt calmer and I stopped getting new ingrowns as my beard grew back.
No stinging, no irritation, and it doesn’t feel greasy. My neck finally looks normal after shaving.

My underarms have never looked this smooth
My underarms used to stay red and bumpy no matter what razor I used. It was itchy, irritated, and made me self-conscious in sleeveless tops. After a couple weeks with this serum, the redness is gone, the bumps disappeared, and my skin feels smooth and healthy. No more hiding my arms, this is a must-have!

Solved my post-barber bumps
I always got ingrown hairs on the back of my head after haircuts. A few days later, bumps would show up every time. I started using this right after my barber visits and the bumps just stopped appearing.
It absorbs fast, doesn’t burn, and doesn’t dry my skin out. Huge difference.

Cleared up my ingrowns fast
My bikini area was always covered in ingrowns because of my thick, coarse hair. Shaving left me with irritation and dark marks that never seemed to fade. This roll-on has been a game-changer within weeks, the bumps calmed down and the spots started to lighten. My bikini line hasn’t looked this clear in years.
FAQ?
Is this safe for my bikini line?

Yes. External skin only (mons pubis, bikini line, inner thighs). Avoid mucous membranes.
Why it's safe: Contains PHA — the gentlest exfoliant recommended for sensitive skin. Patch test if nervous.
Will it burn or sting?

Tend Skin: Alcohol-based. Dries and inflames skin.

Sirencia: PHA (gentlest acid) + licorice root (soothing) + niacinamide (brightening).
