USOLAB Bio Deep Cleansing Water — Exfoliating Toner for Large Pores, Post-Acne Marks and Dull Skin, 200ml

For large pores, blackheads, closed comedones, post-acne marks, uneven texture and dull skin.

An exfoliating toner for the step after cleansing. A cleanser works on the surface; this removes the water-soluble residue left behind and exfoliates the layer of dead cells at the same time.

It stays on the skin and is not rinsed off, so it also does the work of a toner.

The formula is built on four acids that differ in molecule size and solubility, so each one works at a different depth.

PHA (Gluconolactone) — the largest molecule of the four. Works only in the surface layer of dead cells and binds water while it exfoliates, which is why it is used on sensitive and couperose-prone skin.

LHA — a fat-soluble derivative of salicylic acid. Reaches into the pore, but penetrates slowly and stays superficial.

Mandelic Acid — the largest molecule in the AHA group and the slowest to penetrate. Works on texture, tone and post-acne marks.

BHA (Salicylic Acid) — fat-soluble, so it dissolves sebum inside the pore and clears the plug that becomes a blackhead. Anti-inflammatory.

Sodium DNA (Polynucleotides) — stimulates the growth of the skin's own collagen and elastin and supports repair after exfoliation.

Hydrolyzed Hyaluronic Acid — holds water at the surface so the skin does not feel tight afterwards.

Centaurea Cyanus (Cornflower) Flower Water — the base of the formula, in place of water. Calms irritation and settles redness.

Peptide Complex — works on elasticity and skin quality.

Suitable for dehydrated skin as well as oily. The acids here come with hyaluronic acid and cornflower water, so exfoliation does not come at the cost of moisture.

The result: clearer pores, smoother texture, an even tone and no tightness after cleansing.

How to use. Use in the evening. Cleanse first, then dampen a cotton pad and wipe the face. Avoid the eye area. Do not rinse — go straight to serum and cream. Start every other day. SPF every morning.
