Facial Treatments, Product Chemistry, and Ingredients
The basic facial
Consult and analyze, cleanse, exfoliate, steam (distilled water, comfortable distance, brief duration), extract only what is ready, massage, apply a mask matched to the skin, finish with moisturizer and SPF. Massage manipulations: effleurage (gliding), petrissage (kneading), tapotement (tapping), friction, and vibration. Contraindications to massage include active infection, severe acne, recent surgery, and swelling.
Chemistry essentials
Products are solutions, suspensions, or emulsions (oil plus water held together by an emulsifier). Surfactants lift oil and debris; humectants attract water (glycerin, hyaluronic acid); emollients soften; occlusives seal. The pH scale runs 0–14; skin sits near 4.5–5.5, so high-pH soaps strip the barrier. Alpha hydroxy acids (glycolic, lactic) and beta hydroxy acid (salicylic) exfoliate; effectiveness depends on concentration, pH, and free-acid level. Retinol accelerates cell turnover and increases photosensitivity. Vitamin C is an antioxidant that degrades with light and air; niacinamide supports the barrier.
Ingredients and claims
'Natural,' 'organic,' and 'hypoallergenic' do not mean non-irritating or allergy-free. Fragrance and essential oils are common sensitizers. Preservatives are necessary in water-based products. Check comedogenicity for acne-prone clients and always patch test.
Traps
- Layering acids with retinol in one session invites barrier damage - pick one active.
- More percentage is not more results; irritation is a failure, not a sign of progress.
Rule of thumb
Apply products thinnest to thickest: cleanser, toner, serum, treatment, moisturizer, SPF.
