Product Description:

Tired of stubborn blackheads, persistent breakouts, and congested pores? The Cos De Baha (S4) Serum is a high-potency treatment designed for those who need more than just a basic cleanser. Featuring a professional-grade 4% Salicylic Acid (BHA), this serum dives deep into the pores to dissolve the "glue" that binds dead skin cells and excess sebum together.

Unlike lower-strength exfoliants, the S4 serum is formulated to tackle cystic acne and deep-seated congestion while using an Aloe Vera base to help buffer the intensity of the acid.


Why It’s a Blemish-Fighter’s Favorite:

  • Extra-Strength Exfoliation: 4% BHA (Salicylic Acid) is twice the concentration of standard over-the-counter treatments.

  • Deep Pore Cleansing: Effectively dissolves oil and debris to shrink the appearance of enlarged pores.

  • Targets Blackheads & Whiteheads: Clears out existing congestion and prevents new blockages from forming.

  • Reduces Inflammation: Salicylic Acid is naturally anti-inflammatory, helping to calm the redness of active "angry" pimples.

  • Oil Control: Regulates sebum production to keep your skin matte and fresh throughout the day.


Key Ingredients:

  • 4% Salicylic Acid (BHA): An oil-soluble acid that penetrates deep into pores to treat acne and exfoliate.

  • Organic Aloe Vera Leaf Extract: Replaces water as the base to soothe and protect the skin from dryness.

  • Niacinamide (Vitamin B3): Works to fade post-acne marks and improve skin texture.

  • Chestnut Shell Extract: Provides natural tannins to help tighten pores.


How to Use (Crucial Instructions):

  1. Patch Test: Because this is a high-strength (4%) acid, always test a small area 24 hours before full application.

  2. Apply: After cleansing, apply 1–2 drops specifically to "trouble areas" or the entire face.

  3. Frequency: Start by using twice a week. Gradually increase frequency as your skin builds tolerance.

  4. Sun Protection: BHA increases sun sensitivity. You must wear SPF 30+ daily while using this serum.

  • Note: It is normal to experience a "purging" phase where deep clogs come to the surface. This typically subsides within 2–4 weeks.
